Viruses alter plant biochemistry in order to manipulate visiting aphids into spreading infection University of Cambridge researchers have shown that viruses use aphids as pawns, discouraging the insects from permanently settling on already-infected crops and using this forced migration to spread infection to healthy vegetation. Aphids are sap-sucking insects that attack many different types of plants and are major transmitters of crop-infecting viruses. By altering plant biochemistry,...

A new, open-access article (DOI: 10.1603/PM10016) in the Journal of Integrated Pest Management describes the biology and ecology profiles of the soybean aphid (Aphis glycines Matsumura), an insect pest which can reduce soybean yields by $2.4 billion annually if left untreated. The authors review the invasion history and distribution of the soybean aphid, as well as its biology and the feeding damage it causes. Biological control, host plant resistance, and other factors affecting soybean...

University of Illinois researchers identified the top pathogens, pests and weeds affecting soybean production in a recent article in Food Security. Soybean aphid, soybean rust, soybean cyst nematode, Sclerotina stem rot and the exotic pathogen, red leaf blotch, were featured as some of the top biotic constraints that may affect soybean production now and in the future. "Enormous potential exists to increase future soybean production," said Glen Hartman, U of I professor of crop sciences and...

Consumers shouldn't assume that, because a product is organic, it's also environmentally friendly. A new University of Guelph study reveals some organic pesticides can have a higher environmental impact than conventional pesticides because the organic product may require larger doses. Environmental sciences professor Rebecca Hallett and PhD candidate Christine Bahlai compared the effectiveness and environmental impact of organic pesticides to those of conventional and novel reduced-risk...

Research entomologist Louis Hesler takes readers along as he and others search for types of ladybugs that were once common but have become extremely rare in eastern North America I was frustrated. I had been searching for years for the so-called "lost ladybugs," but hadn't found any. It was 2008, and only a few had been found by anyone in the last three decades, although they were once common in many areas, especially crop fields such as wheat and alfalfa. There are actually hundreds of kinds...

University of Illinois researchers recently identified a new soybean aphid biotype that can multiply on aphid-resistant soybean varieties. Soybean aphids are the No. 1 insect threat to soybean production in the North Central region of the United States. Last year, aphid infestation on soybean was high enough that many growers had to spray their fields to control aphids. Despite this, many aphids survived and took flight last fall causing a public nuisance. Migrating soybean aphids have...

Swarms of ladybugs are causing problems for many Americans this season, and even pest control workers are not immune to being bugged. "Every night when I get home and it's dark, I turn on the lights and I have them to greet me. A lot of them," Gene Scholes, entomologist for Reliable Pest Solutions in Quincy, Illinois, told the Associated Press. Scholes uses his household vacuum cleaner to eliminate the massive ladybug swarms. Experts claim that ladybugs form larger swarms on warm days after...

U.S. scientists seeking to avoid using pesticides in controlling soybean aphids are considering genetically modifying soybeans to prevent aphid damage. Iowa State University Professors Bryony Bonning and Allen Miller say if their research is successful, soybeans will carry in-plant protection from aphids, similar to the way genetically modified corn now keeps the European Corn Borer from reducing corn yields. The researchers said their goal is to support development of technologies with...

Two Iowa State University researchers are examining a new method of controlling soybean aphids without the use of chemical pesticides. Bryony Bonning, professor of entomology, and Allen Miller, professor of plant pathology and director of the Center for Plant Responses to Environmental Stresses, are looking at a way to genetically modify soybeans to prevent damage from aphids. If the research is successful, soybeans will carry in-plant protection from aphids, similar to the way genetically...

 This year farmers in the Midwest are growing a new variety of soybeans developed by University of Illinois researchers that has resistance to soybean aphids. However, in addition to the resistant plants, U of I researchers also discovered a new soybean aphid which is not controlled by this resistance.Soybean aphids made their first appearance in North America in the summer of 2000, resulting in tremendous crop losses for farmers. U of I researchers began immediately searching for a...
