Invasive Species.pptx
Invasive species are non-native organisms that cause harm to the environment, economy, or human health. They spread rapidly and outcompete native species due to a lack of natural predators. Common modes of transmission include shipping, boats, wood/soil transport, release of pets/ornamentals, and climate change. Invasive species directly prey on, outcompete for resources, or introduce diseases to native wildlife. They can also indirectly impact ecosystems by altering habitats and food webs. Several invasive plant and animal species from around the world are provided as examples, including their origin, spread, and impacts.
Myoporum Thrips Integrated Pest Management
The myoporum thrips is an invasive pest from New Zealand that is damaging and killing Myoporum plants in California landscapes. It feeds and lives within curled and distorted new growth of susceptible Myoporum species. Monitoring for females on new growth and tapping or shaking plants are effective detection methods. While beneficial insects help control the pest, severe infestations require systemic insecticides. Applying dinotefuran around tree trunks can control the thrips without harming other plants or beneficials as much as other application methods.

Analysis revealed greater populations in the West side and variation among species in different mountain phases. Pteridophytes are abundant and diverse, playing important ecological roles. They thrive between 700-2000m but are threatened by deforestation, with over half considered vulnerable, endangered or threatened. Conservation efforts are needed to address loss of pteridophyte species and habitats from human activities like settlement, industries and tourism.
Giant african snail
The Giant African Snail is a highly invasive pest species native to East Africa. It has spread globally due to accidental and intentional human transport, and is now established on every continent except Antarctica. As one of the world's largest land snails, it consumes over 500 plant species, threatens agriculture and ecosystems, and can carry diseases transmissible to humans. Despite eradication efforts that have cost over $1 million, it remains a persistent invader difficult to control without herbicides or biological controls that may harm other species. Strict prevention of further transport and release is the most effective strategy for limiting its ongoing global spread and impacts.
Giant african snail
The Giant African Snail is a highly invasive pest species native to East Africa. It has spread globally and is known to consume over 500 types of plants. As an introduced pest, it threatens agriculture and ecosystems. Some key points:
- It was first introduced outside of Africa in 1847 in India and has since spread globally except Antarctica.
- In the US it was first found in California in the 1940s and cost $1 million to eradicate in Florida after being introduced as pets in the 1960s.
- It consumes a wide variety of crops and can carry diseases dangerous to humans. Control methods have had limited success and prevention of spread is most effective.

Seminar on Forest and Plant Health (abstracts) 2018Natural Resources Institute Finland (Luke) / Luonnonvarakeskus (Luke)
This document contains summaries of several presentations for the Seminar on Forest and Plant Health on November 7th, 2018 at the Natural Resources Institute Finland in Viikki, Helsinki.
The first presentation provides an overview of the invasive forest pathogen Fusarium circinatum, which causes disease in over 60 pine species. It discusses the pathogen's spread pathways and risk areas, as well as management strategies like prevention, clear-cutting of infested forests, and resistance breeding.
The second presentation reports on a study finding that rust-infected Norway spruce cones in seed orchards are more often infested by the spruce coneworm moth compared to non-rust infected cones, lowering seed quality and quantity.Invasive impact of prosopis juliflora on wildlife conservation and livelihoods
Impact of Prosopis julifora on Conservation of Biodiversity and Livelihoods.
Invasive species are flora and fauna whose introduction into a habitat disrupts the native eco-system. P. juliflora is a shrub or small tree native to Mexico, Central and northern South America. It has shown itself to be a very competitive invader, notably in frost-free arid and semi-arid natural grasslands, both in its native country and in particular, where it is introduced. Prosopis as a genus is treated as one of the world's most detrimental invasive plant species, and P. juliflora is by far the common invasive species. This has led to the proclamation of P. juliflora as an invasive and/or deleterious weed in many African countries notably Ethiopia and Sudan, Pakistan and other Asian countries, Australia and also in South Africa. In further sub-tropical regions such as in Australia and southern Africa, however, it is much less prevalent than additional invasive Prosopis species such as P. glandulosa and P. velutina (the Invasive Species Compendium, also P. pallida with which P. juliflora is often confused). P. juliflora was extensively introduced and planted as a fuel and fodder species, particular during fuelwood programmes in the 1980s, and the seed is spread widely by grazing, wild animals and humans too.
An analysis of the International Union for the Conservation of Nature Red List refers to invasive species as the second most common threat associated with species that have gone completely extinct, and are the most common threat associated with extinctions of amphibians, reptiles and mammals. Majority of endangered wild animals risk projected extinction in coming years through adverse effects caused by Prosopis juliflora. It is a nitrogen-fixing and very drought and salt-tolerant species, which can rapidly out-compete other vegetation. The thorniness and bushy habit of P. juliflora enable it to quickly block paths and make whole areas impenetrable. The specie poses diverse adverse effects to animals as well as endangered wildlife, and sensitization about conservation should be enacted.

Plant Biodiversity Enhances Bees and Other Pollinators in Agro Ecosystems.pptx
In summary, exploring entomology aspects related to plant biodiversity and its impact on pollinators in agro ecosystems highlights several key points. Entomologists study pollinator diversity and foraging behavior influenced by plant diversity. They also assess habitat preferences and health, examining how access to diverse floral resources impacts pollinator populations. Moreover, entomologists investigate pesticide impacts, quantify pollinator contributions to crop pollination, and explore plant diversity's role in supporting natural pest control and climate change resilience. Entomology contributes to conservation by promoting pollinator-friendly practices and educating stakeholders. Overall, these aspects provide a comprehensive understanding of the relationship between plant biodiversity and pollinators, informing sustainable agriculture and biodiversity conservation efforts.
O18 Tooley
This document summarizes the ecology, biogeography, and epidemiology of three devastating Phytophthora species: P. infestans, P. cinnamomi, and P. ramorum. P. infestans causes late blight of potato and tomato and was responsible for the Irish Potato Famine. It has two mating types and long-lived resting structures that allow it to spread over long distances. P. cinnamomi has a very broad host range of over 1000 species and caused major damage to chestnut and eucalyptus forests. It produces thick-walled chlamydospores that allow long-term survival in soil. P. ramorum causes sudden oak
Eucalyptus Redgum Lerp Psyllid Integrated Pest Management
Eucalyptus Redgum Lerp Psyllid Integrated Pest ManagementSchool Vegetable Gardening - Victory Gardens
The redgum lerp psyllid was introduced to California from Australia in 1998 and has since spread throughout the state. It feeds on eucalyptus trees by sucking sap from leaves. Nymphs cover themselves in a white waxy shell called a "lerp". High populations can cause leaf drop and damage trees. A parasitic wasp from Australia provides biological control. Integrated pest management includes cultural practices like irrigation and fertilization to reduce tree stress, as well as monitoring populations and using insecticides sparingly to protect natural enemies.Invasive alien species
The document discusses two invasive alien species: Liriomyza trifolii (American serpentine leaf miner) and Ceratitis capitata (Mediterranean fruit fly). L. trifolii originated in North America and has a wide host range of over 29 plant families. It can develop up to 32 generations per year in tropical areas. C. capitata is native to sub-Saharan Africa and has spread globally through the transport of infested fruits. As a highly polyphagous species, its larvae develop in many fruits including citrus, mangoes, and coffee. Standard control methods for both pests include the use of insecticides and sterile insect techniques.
Papaya ring spot disease
- Papaya ringspot virus (PRSV) has severely impacted Hawaiian papaya production twice since 1937, reducing production by 94% within 12 years after a new strain was introduced in the 1950s. Commercial growers have had to relocate production areas multiple times as the virus spread.
- PRSV exists in two pathotypes - PRSV-P which infects papaya and some cucurbits, and PRSV-W which infects cucurbits but not papaya. Both are transmitted by mechanical means and aphids. Symptoms include mosaic patterns, leaf distortion, and ringspot patterns on fruit.
- The introduction of transgenic resistant papaya varieties in 1998 helped resuscitate the Hawaiian papaya

Regulatory plant pathology rev10.ppt
This document discusses regulatory plant pathology and the spread of plant diseases globally. It summarizes several plant diseases and insects that have spread between continents due to global trade and movement of plant materials. It then outlines the various international, regional, federal, and state organizations that regulate the movement of plants and plant pests, including the International Plant Protection Convention (IPPC) and the North American Plant Protection Organization (NAPPO). It also provides details on regulations in the US, the Plant Protection Act, and the roles of the USDA and Department of Homeland Security in inspecting imports and preventing the introduction of invasive plant pests.
Nematodes 1
A computer-based key for identifying 30 genera of plant parasitic nematodes is described. The key uses Lucid software and is multi-access rather than dichotomous, allowing users to choose observable characters without being limited by couplet structure. Character states like stylet length and shape, body size and shape, and tail morphology are used. Images help non-specialists identify specimens. The key aims to aid identification of nematodes in New Zealand for management and biosecurity purposes.
Key of lepidoptera
This document presents a matrix key for identifying families, subfamilies, and tribes of Lepidoptera (moths and butterflies) found in Canada. It summarizes the key's development based on examination of over 1600 specimens covering approximately 85% of Canadian Lepidoptera genera. The key uses 73 observable external morphological characters to narrow identifications to 222 taxon groups, allowing identification of most microlepidoptera and providing a starting point for macrolepidoptera. It is intended to provide non-experts with a reliable identification tool using only a dissecting microscope.
Diptera
The document summarizes key information about flies in the insect order Diptera. It notes that Diptera have one pair of wings, with the hindwings reduced to halteres. They undergo complete metamorphosis from egg to larva to pupa to adult. As adults, they are usually strong fliers and have large, multifaceted eyes. The order is divided into the suborders Nematocera and Brachycera. Larvae generally lack legs and have chewing mouthparts, while adults feed on liquids and some transmit diseases. Both beneficial and damaging species are discussed.
Lepidoptera key
This document provides a key to identify families of Lepidoptera (butterflies and moths) found in the southwestern United States. It outlines distinguishing characteristics such as whether they are diurnal or nocturnal, presence of frenulum on hindwings, wing pigmentation, antennae features, leg morphology, and markings. The families are grouped by morphological characteristics with the most common ones that will be seen in the field highlighted in bold and marked with an asterisk.
Key words atherigona
This document summarizes a study on the mechanisms of resistance to the sorghum shoot fly, Atherigona soccata, in sorghum. The study evaluated different components of resistance (antixenosis, antibiosis, tolerance) in resistant and susceptible sorghum genotypes under field and greenhouse conditions. Key findings include: 1) Resistant genotypes experienced lower deadheart formation, produced more productive tillers, and insects fed on resistant genotypes had longer larval periods and lower survival rates. 2) Physico-chemical traits like leaf glossiness and trichome density were associated with resistance while chlorophyll content and leaf wetness were associated with susceptibility. 3) Deadheart formation, eggs on leaves, leaf gloss

Since its discovery in the 1980’s, RPW has spread from its native southeast Asia, to every major geographical area, inhabiting many different climates and farming systems. RPW was absent from the Americas until August 2010, when this pest was first detected in the U.S., in Orange County, California. This beetle is not found in Hawaii! DAMAGE AND DETECTION: RPW larvae bore in the soft tissue, tree crown, upper part of the trunk, and the base of petioles in their host plants, causing wilting of crown and leaves. Later infestation detection shows the occurrence of tunnels on the trunk and at the bases of leaf petioles, and through the presence of excrement and brown viscous liquid, which oozes from these tunnels (EEPO 2008, Murphy & Briscoe 1999). Other signs of infestation include “gnawing” sounds and a fermented odor. DESCRIPTION: RPW are large beetles averaging 1.5 inches in length.

RPW may be mistaken for the New Guinea sugarcane weevil, as the sugarcane weevil also attacks palms, especially native Pritchardia spp. RPW is much larger in size than the sugarcane weevil, which reaches only to about a ½ inch in length. RECORDED HOSTS: IMPORTANCE OF PEST: Throughout the world, RPW is a major economic pest, devastating crops of coconut, sage, date, and oil palms (Murphy & Briscoe 1999). In Hawaii, the arrival of RPW would lead to the deterioration of the islands’ economic and cultural palm production. Environmental consequences are also of particular concern, as native palm species may be extremely susceptible to this alien pest. In addition, RPW can be a major safety concern for urban landscaping. Infestations of RPW can lead to palms falling over, possibly leading to injury.
