New soybean pest: Trochanter mealybug

Infestations of the trochanter mealybug (Pseudococcus sorghiellus, in the Order Hemiptera, Suborder Homoptera, Superfamily Coccoidea and Family Pseudococcidae), an unarmored scale insect, were first identified in Midwestern soybean crops in 2008.  They can be found on the roots of soybeans that appear to be suffering from potassium deficiency (yellowing of the leaves).

Andrew Bent honored by Am. Phytopathological Society

Dr. Andrew F. Bent, a faculty member in the UW-Madison department of Plant Pathology, is the 2009 winner of the Noel Keen Award for Research Excellence in Molecular Plant Pathology from the American Phytopathological Society.

This award recognizes contributions to "the understanding of molecular aspects of host-pathogen interactions, plant pathogens or plant-associated microbes, or molecular biology of disease development or defense mechanisms."

Dr. Bent's current research is focused on:

• Leucine-rich repeat (LRR) structure/function, and plant detection of bacterial flagellin
• Study and manipulation of disease resistance in soybean
• Previously unidentified biochemical responses of plants to pathogen infection
