Wheat's genetic resistance to Hessian flies has been failing, but a group of Purdue University and U.S. Department of Agriculture scientists believe that other plants may soon be able to come to the rescue. The Purdue and USDA research team developed a method to test toxins from other plants on Hessian fly larvae. The test simulates the effect of a transgenic plant without the lengthy and costly procedures necessary to actually create those plants. "For years, people have tried to...

Many of the genes that allow wheat to ward off Hessian flies are no longer effective in the southeastern United States, and care should be taken to ensure that resistance genes that so far haven't been utilized in commercial wheat lines are used prudently, according to U.S. Department of Agriculture and Purdue University scientists. An analysis of wheat lines carrying resistance genes from dozens of locations throughout the Southeast showed that some give little or no resistance to the...

Resistant wheat plants stave off attacks by Hessian fly larvae by essentially destroying the fly's midgut and its ability to absorb nutrients, according to a study by Purdue University and the U.S. Department of Agriculture. Hessian fly larvae midguts "“ similar to human intestines "“ were observed in three different feeding situations. Larvae on susceptible plants had normal midgut function. Those that were given nothing to eat showed no damage to the midgut, though they starved....

Agricultural inspectors say a shipment of Chinese fencing infested with caterpillars led to other invasive pests in U.S. imports from the same supplier. The caterpillars were discovered several months ago at the port of Seattle, the Seattle Times reported. Customs and Border Protection inspectors said they were present in unusual numbers. They were everywhere, said Luca Furnare, one of the inspectors. Usually you might actually see a few. But there were so many of them in this case they...
