This research project is collecting data on past pest invasions in both Australia and New Zealand, in order to identify common patterns in plant biosecurity pests.
Our project focuses on modern remote sensing technologies for surveillance and monitoring organisms that threaten plant biosecurity across broad spatial scales.
This document discusses the development of a national fruit fly research, development and extension plan in Australia. It notes that fruit flies significantly impact the horticulture industry, costing over $270 million annually. It outlines that a national strategy and implementation plan have already been developed. A writing group is creating a 20-year RD&E plan to support a coordinated national approach to managing fruit flies. Regional workshops were held between June and August 2015 to identify research priorities. The goal is to reduce treatment costs, improve fruit fly control programs, and facilitate domestic and international trade of Australian horticultural products.
Three years of research to date have produced a robust, accurate, sensitive detection tool and sampling strategy for the damaging apid-like insect phylloxera (Daktulosphaira vitifoliae), which feeds on grapevine roots
Invasive pests and pathogens can have devastating and unpredicted impacts on native ecosystems. The threat that Puccinia psidii (myrtle/eucalyptus/guava rust) posed to Australian industries was well recognised, but until its introduction in 2010, there was scant consideration of the impacts this disease may have on endemic Myrtaceous plant species and associated communities in native environments. Since its detection in Australia, the distribution and host range of P. psidii has rapidly expanded and entire species and plant communities are now under threat.
The research being undertaken into myrtle rust has enabled improved species selection for production and retail nurseries, and for urban tree planting.
The document discusses the development and deployment of genome-informed diagnostic protocols for plant pathogenic bacteria by the Plant Biosecurity Cooperative Research Centre (PBCRC). The PBCRC has developed and validated laboratory and field diagnostic protocols to discriminate bacteria at the pathovar level using genome sequencing and bioinformatics. It has also trained scientists in plant bacteriology and engaged end-users in field testing and validation of new diagnostic technologies and protocols.
The Australia-Africa Plant Biosecurity Partnership has brought together plant biosecurity professionals in ten African countries and established linkages with Australian researchers, helping
to reduce pest and disease impacts in sub-Saharan Africa. At the outset of this initiative, diagnostic skills were identified as a priority area in connecting Australian expertise with Africa and improving surveillance capability, post-entry quarantine, early warning and phytosanitary certification. This presentation will briefly examine the application of improved diagnostic skills in African Plant Protection Organisations and the longer term relationships that have been established with Australian mentors.
This multifaceted project is seeking to protect the grains industry by improving the robustness and efficiency of the pest management and plant biosecurity system.

Long distance natural (wind-assisted) dispersal of exotic plant pests and pathogens into Australia, is a very real and underestimated, biosecurity risk.
This document summarizes a presentation on using next generation sequencing (NGS) to improve virus and viroid detection for plants in post-entry quarantine (PEQ). Current PEQ diagnostic methods are slow and can miss pathogens. The presentation describes how NGS allows rapid and reliable detection of viruses without prior knowledge. A project found viruses in 68% of plant samples tested using NGS compared to traditional methods. NGS could reduce PEQ time from over 2 years to 6-12 months. Industry representatives expressed support but want more validation before fully adopting NGS for high-stakes pathogen testing and certification schemes. The project aims to provide more evidence and training to facilitate adoption of NGS for improving plant biosecurity.
This document discusses improving biosecurity for Australia's winter cereal industry. It summarizes that current post-entry quarantine regulations are inadequate and represent an unacceptable biosecurity risk. It has identified high priority exotic viruses as quarantinable risks based on national threat assessments. Diagnostic tests have been developed for 14 priority viruses that could be introduced through imported seed or other pathways. Recommendations include implementing improved post-entry quarantine protocols for cereals and adopting standard operating procedures for virus screening at the border.
The development of insect resistance to the key fumigant phosphine is driving renewed interest in the development of alternatives. One such alternative is the use of low oxygen atmospheres that are usually created through the generation of nitrogen. However, the costs of nitrogen generation have
been a longstanding barrier to the adoption of the low oxygen atmospheres in agricultural storages such as grains.
The research team has taken advantage of recent advances in the cost of nitrogen generation (membrane technology) to assist industry overcome operational barriers to uptake of the
technology.
This document summarizes a research project studying the molecular response of tephritid fruit flies to sublethal stresses. The project aims to:
1) Identify the molecular pathways activated in fruit flies exposed to heat, cold, radiation, and parasitic infection stresses.
2) Construct a regulatory network of stress response genes in two key fruit fly pests.
3) Validate specific genes' roles in stress response through functional assays.
The goal is to develop more effective and environmentally friendly postharvest treatments for controlling fruit flies, providing benefits to the horticulture industry, government pest management strategies, and researchers.
An optimal surveillance system is one where the available sampling resources are allocated in time and space to best achieve detection objectives. This project aims to develop new methods for designing optimal surveillance systems that properly account for organism biology, trapping or sampling efficacy, and landscape characteristics.
Here we update on fundamental systematics research and the development of new potential molecular markers to improve on current diagnostic tools. We also link these molecular tools with physical specimens, documenting the range of morphological variation so as to greatly improve on available resources used to diagnose fruit flies in the field as part of surveillance programmes or at border interceptions.
The Global Eradication and Response Database (GERDA) summarises incursion response and eradication programmes from around the world. The purpose of GERDA is to determine which characteristics lead to the success or failure of eradication programmes.
This document discusses the development of a protocol for detecting the grape pest phylloxera using quantitative PCR (qPCR) in soil samples. The objectives are to create a sampling and detection method that is accurate, sensitive, cost-effective and can be applied to other pests. It aims to obtain endorsement to incorporate the qPCR method into the national phylloxera management standard. The research aims to benefit the wine industry through improved surveillance and early detection of phylloxera, as well as regulators and researchers.
There are many facets involved in the development of biogeochemical markers that might enable the geographic origins of fruit flies to be distinguished.
Using growing degree days for pest management by p.manikandanblacken323
This document discusses using growing degree days (GDD) for pest management in agriculture. GDD is a measure of heat accumulation that farmers can use to estimate the growth stages of crops, weeds, and life stages of insects. GDD is calculated based on daily maximum and minimum temperatures compared to a base temperature, usually 10°C. Tracking GDD is more accurate than calendar timings alone for determining current insect activity and development. The document provides examples of specific GDD thresholds for pest development and control, noting that timing pest management strategies based on insect GDD can be more precise than calendar methods.
This project has developed new ‘Smart’ Spore and Insect Trapping systems for target(s) surveillance referenced to GPS and climate data (temp, wind direction, RH), or wireless data transmission for improved compatibility to rapid and accurate downstream diagnostics.
Myrtle rust (Puccinia psidii) is an invasive fungus native to South America that was first detected in Australia in 2010. It has spread rapidly along the east coast, and is currently recorded in sites as far north as the Northern Territory and south to Tasmania.
In order to better understand myrtle rust extent and impacts in Australian native and managed landscapes, a survey was sent to national parks, botanical gardens, councils, natural resource
managers, nurseries and forestry agencies in all states where the fungus is present (NT, QLD, NSW, VIC and TAS). The survey revealed that Myrtle rust is widespread in NSW and QLD gardens and streets as well as in native vegetation.
Radioactive pollution is defined as the increase in the natural radiation levels caused by human activities. The human activities that can release radiation involve activities with radioactive materials such as mining, handling and processing of radioactive materials, handling and storage of radioactive waste, as well as the use of radioactive reactions to generate energy nuclear power plants , along with the use of radiation in medicine e.g. X rays and research. Dr Sangeeta Gautam | Vijay Aithekar "An Review Article on Radioactive Pollution" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-5 , August 2019, URL: https://www.ijtsrd.com/papers/ijtsrd26373.pdfPaper URL: https://www.ijtsrd.com/chemistry/other/26373/an-review-article-on-radioactive-pollution/dr-sangeeta-gautam
Up until mid-2016, citizen science uploads to the Atlas of Living Australia (ALA) included c. 400 bug species, and c. 1,000 beetle species. Given the short time period (c. 3 years) over which most of these records have accumulated, this represents a considerable reporting effort. The key question from a plant biosecurity context is how this level of reporting translates to the detection and reporting of
exotic insect pests in the event of an incursion.
This document summarizes a research project that aims to develop accurate and rapid diagnostic tools for detecting exotic bacterial plant pathogens through genome-informed design. The project is developing PCR and LAMP-based diagnostics for key pathogens like Erwinia amylovora and Xanthomonas citri. Field-deployable tools like LAMP and RPA are also being validated for "smart surveillance" directly in the field. The diagnostics and training provided by this research will benefit biosecurity agencies, diagnostic laboratories, and the horticultural industry by facilitating early detection and a rapid response to incursions.
This document discusses the use of genome-informed diagnostics to better inform biosecurity decisions for managing Pseudomonas syringae pv. actinidiae (Psa), the bacterial disease affecting New Zealand's kiwifruit industry. It provides details on the current situation of managing Psa over the past 6 years, the control efforts in place including a national pest management plan and R&D program, and the trade and economic consequences of estimated losses of nearly $1 billion over 15 years. It also notes the necessity of diagnostic tests to differentiate Psa strains to maintain important trade.
Biosecurity issues impact on key crops and environmental values across NZ and Australia. A key outcome for the project team will be the ability of indigenous communities, and relevant regulatory authorities and industries, to better manage the social, environmental and economic impacts of biosecurity threats, and to participate in biosecurity strategies through improved bicultural engagement models that build empowerment and ownership in indigenous communities and their response to those threats. The teams have developed an engagement model adapted to the indigenous peoples and their communities of each country.
Modern biocontrol agents and biofertilizers provide alternatives to pesticides and synthetic fertilizers with benefits including fewer available pesticides, a wider range of biocontrol agents, and improved formulations. Biofertilizers can fix nitrogen, mobilize phosphorus and micronutrients, and help plants tolerate stresses like heat, cold, and drought. Soluble silicon is also effective for stress tolerance and synergizes with biocontrol agents. Effective registration and commercialization of products requires screening to find adapted, powerful strains and ensuring proper formulations, spore counts, and viability.
Trees go through a life cycle starting as a seed that grows into a seedling and then a tree. As a tree it will grow flowers that become fruit. There are over 100,000 types of trees worldwide. Trees are plants as they do not move and get their food through photosynthesis rather than hunting for it like animals. Trees can grow in many places including forests, jungles, backyards and parks as long as they have sun, soil, water and a warm environment. Their bark protects the inside and trees stand upright due to their strong root system.

Biological control of plant pathogens using beneficial microorganisms like Trichoderma spp. fungi is an alternative to chemical pesticides. Trichoderma controls pathogens through antibiosis, nutrient competition, and mycoparasitism. Successful biocontrol requires a highly effective strain that can compete, persist, and colonize plants without being pathogenic. The strain must also be producible at large scale and remain viable after formulation. Trichoderma is commonly used as a biocontrol as it is present in soil and able to colonize plant roots, protecting against diseases through mycoparasitism and inducing host resistance.
10 lecture 1 principles of disease managmentZulfa Ulinnuha
1. The document discusses principles of plant disease management, including strategies to exclude pathogens before infection or treat plants after infection occurs.
2. It describes concepts like disease cycles, epidemiology, and the disease triangle that influence management approaches. Polycyclic diseases require reducing infection rate while monocyclic diseases focus on reducing initial inoculum.
3. Successful management combines strategies like sanitation, resistant varieties, and fungicides to manipulate the disease triangle and limit disease development over time.
The document discusses various training methods used to equip employees with necessary skills and knowledge. It describes on-the-job training methods like coaching and mentoring which involve learning on the job from managers. Off-the-job methods like vestibule training, role playing and lectures are conducted away from the workplace to allow full concentration on learning. Both approaches have advantages like cost-effectiveness and allowing specialized training, and disadvantages such as disruption to work or requiring skilled trainers. The goal of training is to increase productivity, safety, and employee satisfaction through continual skills development.
Art is a creative expression that stimulates the senses or imagination according to Felicity Hampel. Picasso believed that every child is an artist but growing up can stop that creativity. Aristotle defined art as anything requiring a maker and not being able to create itself.
This document discusses integrated plant management strategies for billbug control and Poa annua control at The Rim Golf Club in Payson, Arizona. It outlines the use of degree day models to time applications of chemical and biological controls based on insect and plant development. Specific techniques mentioned include using degree days to guide the timing of chlorpyrifos and clothianidin applications for billbug adult and larvae control between 280-1485 growing degree days. It also discusses using a degree day model between 400-1400 days to target seedhead production in Poa annua and control methods like herbicides and a Xanthomonas bacteria.

Total Greenhouse Management® 6 years implementation in 10 ha glasshouse area ...Christina Papaioannou
This document summarizes a 6-year case study of whitefly management in a 10-hectare greenhouse in Northern Greece. The study utilized an integrated pest management approach considering principles of environmental sustainability, food safety, and market demands. Key factors for effective whitefly management included high hygiene status, adequate scouting levels, targeted chemical applications, proper introduction of predatory mites like Macrolophus caliginosus and Euseius eremicus, and quickly addressing any issues like broken insect nets. With the total greenhouse management approach, the grower was able to balance economic results, consumer safety, and business sustainability.
What is an optimal spray threshold which results in optimal yield protection?Jennifer Blackburn
1) Researchers conducted field experiments across 5 states and 6 locations to determine optimal spray thresholds for protecting sorghum yield from aphid damage.
2) Results showed that economic thresholds varied by location but generally ranged from 30-135 aphids per leaf. Lower thresholds were recommended for more susceptible hybrids or under hot/dry conditions favoring aphid increase.
3) Next steps include investigating surrogate measures for estimating aphid loads, effects of plant stage and health, hybrid sensitivity, and natural enemies to refine economic thresholds.
The document provides an overview of genetically modified organisms (GMOs) including what constitutes a GMO, procedures that do not result in GMOs, key duties regarding contained use of GMOs, risks associated with GMOs, classification of GMOs, and what to do in the event of a spill in a containment level 2 laboratory. It defines GMOs and discusses bacterial expression systems used to produce proteins of interest from gene inserts. It also outlines the risk assessment approach and regulations for working with GMOs.

New breeding tool i.e. speed breeding (indoor plant breeding technique)to enhance the life cycle of crop. The concept involves exposing plants to an inordinate amount of light in a close green house environment in an efforts to speed up the growing process and produce new generation of seeds in a much quicker fashion
Implementation of Protected Cultivation Technologies pramodrai30
This presentation discusses various low-cost protected cultivation technologies for farmers. It begins with an introduction to protected cultivation and its benefits over traditional open-field cultivation. It then describes several low-cost structures in detail, including low-cost natural ventilated greenhouses, multipurpose greenhouses, shade net structures, and detachable roof greenhouses. For each structure, it provides dimensions, materials used, environmental controls possible, suitable crops and seasons. It concludes that these low-cost protected structures allow year-round cultivation and higher yields compared to traditional practices.
This document summarizes different modeling methods for predicting insect population dynamics under varying environmental conditions. It discusses three main types of temperature-based models: degree day models, nonlinear models, and distribution delay models. Degree day models assume development is based on thermal time units but do not account for individual variation. Nonlinear models use exponential or logistic functions to model temperature effects but have limited applicability. Distribution delay models account for variation in development times. The document recommends future models incorporate additional environmental factors and individual variability to improve prediction accuracy.
The document discusses methods for producing clean planting material of banana and plantain through in vitro culture. It describes techniques for virus elimination including meristem culture, thermotherapy, and chemotherapy. Meristem culture is most effective for phloem-associated viruses like BBTV but less so for viruses in meristematic domes like CMV. Thermotherapy depends on virus type and has an unknown mode of action. Chemotherapy has been tested with various compounds and is more effective against CMV. A combination of techniques like meristem culture and thermotherapy can achieve high elimination rates of viruses like CMV and BSV. Challenges remain regarding fully cleaning viruses from plant material.
Evaluation of Biocontrol agents against Lasiodiplodia theobromae causing Infl...IOSR Journals
This study evaluated the biocontrol potential of Trichoderma viride and Aspergillus niger against Lasiodiplodia theobromae, the causal agent of inflorescence blight disease in cashew. In dual culture tests, both T. viride and A. niger significantly inhibited the growth of L. theobromae compared to the control. A. niger exhibited the highest inhibition, reducing pathogen growth by 74.7% in one technique. In a second technique, T. viride showed the strongest antagonism, limiting pathogen growth by 90.5%. The study suggests that both tested biocontrol agents, particularly A. niger, have potential for managing inflorescence

The document discusses biosafety and genetic engineering. It defines biosafety as protecting health and the environment from modern biotechnology. The Convention on Biological Diversity and Cartagena Protocol on Biosafety established frameworks for regulating risks from living modified organisms. Genetic engineering differs from traditional breeding by allowing transfer of genes across species barriers and precise introduction of single genes. Safety assessments of genetically modified foods examine potential allergenicity, toxicity, and nutritional impacts. Overall biosafety requires case-by-case scientific evaluation of risks and benefits.

There are several risks that need to be considered for pests and disease in the closed ecological environment of the AgriPOD greenhouse system. Key pests include rats and mice (risk level 2), aphids (risk level 3), and fruit flies (risk level 3-4). Disease risks can be mitigated by maintaining proper hygiene, humidity, water quality, and growing conditions for hydroponic plants. Overall, the enclosed nature of the AgriPOD system helps reduce pest and disease risks compared to a traditional greenhouse. Proper protocols, trained staff, and integrated pest management strategies can help avoid, eliminate, and mitigate the identified risks.
Avoidance from Dengue by Microencapsulated with Vetiver root Essence with mos...ijtsrd
Objective: This study was conducted to design the textile structured dress of knitted materials with mosquito repellent behavior using micro-encapsulated Vetiver root extract on a fabric to prevent from Dengue.

Computer models and software are used to forecast pest attacks and identify pests based on weather data, pest population data, and crop information. Weather-based models use degree-days and temperature thresholds to predict pest development. Simulation models use mathematical descriptions of pest biology. Remote sensing, GPS, and GIS integrate spatial data to map pest distributions. Examples provided include models for locusts, corn borers, rice pests, and apple/potato pest software. Accurate forecasts allow timely pest management decisions like spraying or varietal selection.
CRISPR/Cas9 has potential applications for genetic engineering in plants. It allows for efficient and targeted mutagenesis. Researchers disrupted the RIN gene in tomatoes using CRISPR to inhibit fruit ripening as a proof of concept. CRISPR was also used to interfere with viral replication and reduce symptoms of viral infection in plants by targeting conserved regions of viral genomes. While promising, CRISPR gene editing raises regulatory concerns and potential off-target effects require further exploration.
The document discusses plant disease forecasting. It provides information on:
1. The principles of disease forecasting are based on the nature of the pathogen, environmental effects on pathogen development, host response to infection, and grower activities.
