Worker ants from a particular species of African ants have potent venom that can paralyze and kill termites from a distance, according to a study published Dec. 14 in the online journal PLoS ONE. The research, conducted using a species called Crematogaster striatula, showed that chemicals the worker ants emit from their stinger have three functions: they attract nearby nestmates; repel alien ants; and paralyze and kill termites. While the first two effects require the ants to come into...

Inbreeding Could Be Key Cause Of Bed Bug Infestations

As bed bug populations spread throughout the United States, scientists at ASTMH meeting release new research on their biology and behavior New research on the bed bug's ability to withstand the genetic bottleneck of inbreeding, announced Dec. 6 at the American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting, provides new clues to explain the rapidly growing problem of bed bugs across the United States and globally. After mostly disappearing in the US in the 1950s, the...

Pollution growing particularly in the Baltic Sea region according to study Europe's streams will in future be more heavily polluted with insecticides than before. This is the conclusion of a study by the Helmholtz Centre for Environmental Research (UFZ) for which scientists compared the situation of 1990 with climate and land use change scenarios in 2090. The risks for streams caused by the use of insecticides in agriculture will increase significantly in many regions of Europe, and...

U.S. Department of Agriculture (USDA) scientists are showing Arizona cotton growers how to reduce their dependence on broad-spectrum insecticides by controlling sweetpotato whiteflies with greener alternatives. Some Arizona growers continue to combat whiteflies with broad-spectrum insecticides that wipe out a number of insects, despite the availability of sprays that specifically target whiteflies. Steve Naranjo, a scientist with USDA's Agricultural Research Service (ARS), and Peter...

Bed Bug Insecticide Resistance Mechanisms Identified

Bed bugs, largely absent in the U.S. since the 1950s, have returned with a hungry vengeance in the last decade in all 50 states. These insects have developed resistance to pyrethroids, one of the very few classes of insecticide used for their control. A research team at Virginia Tech has discovered some of the genetic mechanisms for the bed bug's resistance to two of the most popular pyrethroids -- deltamethrin and beta-cyfluthrin. The discoveries will accelerate efforts to understand the...

Improper use of insecticides by individuals looking to kill bedbugs resulted in 80 illnesses and one fatality over a three-year period, according to a Centers for Disease Control and Prevention (CDC) report released on Thursday. The CDC study included data from 12 states, only seven of which -- California, Florida, Michigan, New York, North Carolina, Texas and Washington -- reported illnesses that resulted from bedbug insecticides. Most of the cases originated from New York City, "the home...

When wireworms feast on potatoes, the results aren't pretty: The spuds' surfaces are left punctured, pitted and unappealing. For the past few years, U.S. Department of Agriculture (USDA) scientists and their colleagues have sought a solution in the form of spuds with genetic resistance to the worms, with special attention focused on two wild potatoes from Chile and Bolivia: Solanum berthaultii and S. etuberosum. Previous studies showed that the wild potatoes resisted Colorado potato...
