Understanding Cycles of Pests and Diseases and Their Interaction with the Environment

For farmers, successful use of cultural disease and insect pest management methods to prevent and/or avoid problems before they occur depends on an understanding of pathogen and pest life cycles and also how their development may be affected by weather conditions.  In this workshop, vegetable disease and insect pest management experts will discuss life cycles of key disease pathogens and insect pests affecting vegetables both above and below-ground. They will also explain how growers may use this information to implement certain cultural management practices that help to prevent or avoid disease and pest problems, and how changes in weather can affect disease and pest development. The workshop will conclude with a session on selection and application of organic insecticides for use in vegetables. Continue reading

UK scientists identify important biological marker to control insect pests

by Katie Pratt, University of Kentucky

A University of Kentucky research team led by entomologist Subba Reddy Palli discovered a protein that plays a critical role in the effectiveness of RNA interference in beetles. This finding could improve the efficiency of this pest control technology and help manage resistance.

RNA interference, RNAi, is a process where RNA molecules constrain gene expression. It is very efficient in insects belonging to the order Coleoptera, which includes a variety of major pests such as the corn rootworm, Colorado potato beetle, pine weevil, powderpost beetle, Asian longhorned beetle and emerald ash borer. However, it has varying levels of efficiency in other insects. Continue reading

APHIS adds all of Minnehaha County, areas in Lincoln County, and areas in Turner County in South Dakota to the regulated areas for the emerald ash borer, Agrilus planipennis

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is adding all of Minnehaha County in South Dakota and areas north of Highway 18 in Lincoln County and north of Highway 18 and east of Highway 19 in Turner County in South Dakota to the list of regulated areas for the emerald ash borer (EAB). APHIS is taking this action in response to the expansion of EAB in these areas.

To prevent the spread of EAB to other states, the attached Federal Order outlines specific conditions for the interstate movement of EAB-regulated articles from the quarantined area. Specifically, the interstate movement of EAB-host wood and wood products from the quarantined areas is regulated, including firewood of all hardwood species, nursery stock, green lumber, waste, compost, and chips of ash species.

Atrazine Human Health Risk Assessment Now Available for Public Comment

Today, the Environmental Protection Agency is releasing the atrazine draft human health risk assessment for public comment. The assessment identifies potential risks to children who crawl and play on lawns sprayed with atrazine and to workers who apply atrazine and/or enter treated fields after application.

Atrazine is one of the most widely used agricultural pesticides in the United States. It is used to control broadleaf and grassy weeds on corn, sorghum, and sugarcane, and to a lesser extent on residential lawns and golf courses. In the assessment, EPA reviewed all available scientific data, including published toxicity and epidemiology literature. The assessment uses multiple lines of evidence and methodologies that reflect current science. Continue reading

Research targets insect pests of pulse crops

Around the world, pulse crops–such as beans, peas, chickpeas, and lentils–are an important staple in the modern food supply, and their cultivation is growing in the United States and many other Western countries. As in any agricultural system, though, pulse crops can fall victim to a wide range of insect pests.

Pulse crop growers facing pest management challenges will soon have a new set of resources to tap into with the July issue of the Annals of the Entomological Society of America. The issue features a special collection with nine articles on pulse crop insect pests and management strategies. Continue reading
