Evidence of a Sexual Life Cycle in Sugarcane Aphid
1) While sugarcane aphids are generally considered to reproduce via viviparity without sexual forms, some literature reports observations of oviparous adults, sexual reproduction, and eggs.
2) A sexual life cycle could help explain how sugarcane aphids rapidly shifted to infesting sorghum.
3) Historical reports describe oviparous morphs appearing after the 16th generation under average temperatures of 17.7°C and photoperiods of 11:13-10:14 hours, with eggs found on sorghum and Miscanthus plants.
What is the Baseline Susceptibility of Aphids to Transform and Sivanto Prime?
This document summarizes research establishing baseline data on the susceptibility of sugarcane aphids to the insecticides Transform (sulfoxaflor) and Sivanto (flupyradifurone). Leaf dip bioassays were conducted in 2014-2015 at multiple locations. The results found sulfoxaflor to be slightly more toxic to sugarcane aphids than flupyradifurone. Toxicity levels varied regionally but were not correlated between the two insecticides. Sulfoxaflor susceptibility decreased slightly from 2014 to 2015. Continued monitoring is needed to track potential shifts in insecticide susceptibility over time.
Developing a sampling plan for sugarcane aphid in sorghum
This document discusses developing a sampling plan for sugarcane aphid in sorghum. There is currently no efficient, user-friendly sampling system to determine sugarcane aphid density and evaluate if treatment thresholds have been met. The authors and collaborators from multiple states aim to characterize the seasonal distribution of sugarcane aphid within sorghum fields and plants. They will develop sequential and binomial sampling protocols, validate the protocols using natural infestations, and create a decision-making tool for sugarcane aphid management. The work is funded by a USDA NIFA grant.

También cubre sus enemigos naturales, el umbral de decisión para el control químico, y los insecticidas registrados para su control.
Confirming the Documented Graminous Host Range for Sugarcane Aphid
The document summarizes research identifying and verifying documented graminous hosts of the sugarcane aphid (Melanaphis sacchari) through a literature review and container study. The container study tested 35 grass species and found persistent sugarcane aphid populations on pearl millet, sorghum, Johnson grass, broom corn, and sudangrass. Non-persistent populations were found on large crabgrass, jungle rice, barnyardgrass, Japanese millet, napiergrass, sugarcane, and corn. The sugarcane aphid failed to feed on oats, rye, wheat, rough barnyardgrass, annual ryegrass, and switchgrass. The discussion
Antibiosis to SCA in Pl 550610 and SCA-Greenbug Interactions
The document summarizes research on the interactions between sugarcane aphid (SCA) and greenbug aphid (GB) on susceptible and resistant sorghum plants. It finds that:
1) A resistant sorghum variety (PI 550610) reduced the survival and development time of both SCA and GB nymphs, eliminating the developmental advantage of SCA.
2) On susceptible plants, co-infestation of SCA and GB had mixed effects - improving GB reproduction but decreasing SCA reproduction. On resistant plants, co-infestation harmed both species.
3) The research suggests plant resistance and aphid interactions can change from commens

This document discusses policies and strategies for using information and communication technologies (ICTs) to reduce rural poverty in Africa. It recommends that governments adopt policies to increase rural access to ICT facilities and prioritize applications that support rural development goals. Successful country examples integrate ICT strategies into poverty reduction plans and prioritize initiatives that connect rural communities, support agriculture and resource management, and create public access points. However, challenges remain around limited infrastructure, investments, and private sector involvement in rural areas. Overcoming these challenges could help countries meet their Millennium Development Goals by empowering rural communities through ICT access.

This document discusses the effects of different source and streamer datum correction techniques on seismic image quality and resolution. It focuses on analyzing the advantages and disadvantages of three techniques - bulk static shift, intermediate static shift, and dynamic correction using NMO - on both real and synthetic deep tow seismic datasets. Statistical and spectral analysis is used to assess the differences between the techniques and determine the optimum method. While the dynamic correction yields superior results, the improvement is not significant enough to warrant changing from the currently used bulk static correction. However, as acquisitional advances continue to be made, it will be important to keep investigating optimum datuming methods to ensure high quality final images.
Scope and aims of physiotherapy
Physiotherapy scope i.e. areas and fields where it is used.
Who is a physiotherapist, how does he/she diagnose and give treatment.
Case study of iconic director
Alfred Hitchcock was known for using dark lighting, shadows, and black and white filters in his films, especially thrillers, which commonly employ dark lighting to build tension. He also favored bold, bright opening titles unlike typical thriller titles. Additionally, Hitchcock often shot scenes in empty outdoor settings like fields or isolated buildings to create a sense of mystery and isolation. Some of his most famous films include Psycho, Rear Window, Vertigo, and Dial M for Murder.

This document summarizes research on the impact of different adjuvants on the efficacy of Transform and Sivanto for controlling sugarcane aphids. The research involved field trials in multiple states comparing the insecticides alone and with various adjuvants. The results showed that adjuvants did not significantly improve control of sugarcane aphids compared to the insecticides alone. Yield was also not significantly increased by any treatment. The document concludes that adjuvants did not enhance control in these trials and makes suggestions for future research such as comparing aerial and ground applications.
Refugees and migrant workers
Migrants choose to leave their home country for economic opportunities elsewhere and are free to return, while refugees flee persecution and risk of harm. Refugees have rights including not being returned somewhere they face danger and access to public services. The main drivers of migration are economic hardship and opportunity, while war, unrest, and disasters spur refugees. Both groups contribute benefits like filling jobs and economic growth, but migrants face challenges with conditions, culture, education.
Human rights
The document discusses the international legal framework protecting the right to health for refugees and migrants. It explains that refugee law and international human rights law both establish rights to health. Refugee law requires countries to provide lawfully staying refugees access to social services like health care equivalent to nationals. The International Covenant on Economic, Social and Cultural Rights and International Covenant on Civil and Political Rights establish rights to health and non-discriminatory access to health services. However, migrants still face barriers to realizing these rights in practice due to discrimination, social attitudes, and legal status restrictions.
Fivay Athletics Jan 18-23
The document lists various sporting events for boys and girls soccer, basketball, and wrestling taking place from January 18-23. It schedules boys soccer and basketball games against Hudson and Nature Coast at home on the 18th, with additional boys soccer, basketball, and wrestling matches through the 23rd, including district tournament games for boys soccer at Ridgewood and a wrestling dual tournament on the 23rd.
Combination of Harvest Aids with Insecticides
- The document examines the combination of harvest aids (glyphosate, sodium chlorate) and insecticides (Transform) to control sugarcane aphids in grain sorghum at harvest.
- Field trials showed that sodium chlorate significantly reduced aphid populations on flag leaves within 3 days, while glyphosate did not. Applying an insecticide with a harvest aid further reduced aphid numbers and no aphids remained after 13 days.
- No mechanical issues occurred during harvest and grain yields were not significantly different between treatments. Further research is needed to determine action thresholds for harvest aid application and how long aphids remain on plants after treatment.
Local Air Quality Management (LAQM) and Cleaner Air for Scotland (CAFS)
Local air quality is currently managed through the local air quality management (LAQM) system established by the Environment Act 1995. This system involves local authorities reviewing air quality, declaring air quality management areas if standards are not met, and taking action. The Cleaner Air for Scotland (CAFS) strategy aims to develop LAQM and ensure air quality impacts are considered in regional decision making. Several options were discussed for better aligning LAQM and CAFS, including reinterpreting existing legislation, updating guidance to incorporate CAFS requirements, or changing legislation, but no clear preferred approach was identified. Input from others is sought on the best way forward.
DSL简介
DSL is a computer language specialized to a particular application domain, in contrast to a general-purpose language (GPL) that is broadly applicable across domains. There are several common ways to implement a DSL, including using parsers to convert DSL scripts into semantic models or abstract syntax trees that can then be used to generate executable code. DSLs allow expressing solutions to problems in a particular domain in a simpler and more natural way than GPLs.
