Summary

​This presentation will help consultants, growers, and other practitioners in the soybean growing regions of the U.S. and Canada learn more about the spread and potential impact of brown marmorated stink bug (BMSB) on soybean. BMSB, a native species of Asia, was first identified in the U.S. in 2001 in Allentown, PA. It has since spread throughout much of the U.S. and in the mid-Atlantic states is causing near catastrophic levels of damage to many horticultural crops including fruits, vegetables, wine grapes, and others. It is also been documented as a pest of soybean, especially in Maryland, and is spreading south and westward. This presentation will provide images of BMSB injury to soybean pods, seed, and the ‘stay-green’ condition in fields; preliminary results of in-field distribution studies and field cage studies to measure impact to soybean; limited results of insecticide effectiveness studies; and preliminary management recommendations. By the end of this presentation, the practitioner should know more about BMSB’s current distribution in U.S. soybean, how to identify soybean injury symptoms, preliminary field scouting procedures, and preliminary control recommendations.

About the Presenter

Ames Herbert Jr.​ Ames Herbert, Jr., develops (research 25%) and implements (Extension 75%) programs to improve management of insect pests of soybean, peanut, cotton, and small grains that reduce reliance on pesticides yet maintain crop quality and profitability. He works collaboratively with grower and industry groups, Extension agents, and university and agency personnel and provides leadership to departmental, college, VCE, and university committees and programs. Currently, he is the State IPM Coordinator and Extension Project Leader for the Department of Entomology. Projects include research with use of soybean leaf area (LAI) to assess insect defoliation and aid in management decisions, evaluation of GMO insect-resistant cotton varieties and development of new thresholds for hemipterous pests of cotton, evaluation of peanut cultivars and tobacco thrips management practices for limiting incidence and losses to tomato spotted wilt virus, survey and management of stink bug species in soybean, survey and assessment of native stink bug egg parasitoid species, and research on efficacy of insecticide seed treatments for control of early season insect pests of cotton, small grain and soybean.​
