Location: Southern Insect Management Research
2021 Annual Report
Accomplishments
1. Efficacy of Beauveria bassiana and other biocontrol agents for control of the tarnished plant bug and other insect pests. Microbial insecticides are an important component of many insect pest management programs. ARS researchers in Stoneville, Mississippi, quantified the impact of the native strain NI8 on feral populations of tarnished plant bugs and its possible impact on beneficial arthropods. Continuation of laboratory and field experiments has determined mortalities and estimate lethal doses of potential microbial insecticides including the native Delta strain NI8 and the commercial strain GHA on feral tarnished plant bug populations and southern green stink bug on cotton and soybean were completed and prepared for publication. These studies will impact the development of non-chemical control methods used in cotton integrated pest management systems across the southern United States.
