Brief Project Summary:
In recent years we have observed a resurgence on the populations of bean leaf beetles (BLB), the expansion of the brown marmorated stink bug (BMSB) in western Kentucky in 2020, and the increased presence of grape colaspis (GC) beetles and three-cornered alfalfa hoppers (TCAH). This proposal will continue evaluating the efficacy of single and double mode of action insecticides for the management of BLB and stink bugs; and the secondary pests cited above. BMSB is an invasive species that has more tolerance to pyrethroids that endemic stink bugs, and the TCAH caused an outbreak in Butler Co. in 2020. Studies will be conducted at the Research and Education Center in Princeton and through visits...

Project Summary

In recent years we have observed a resurgence on the populations of bean leaf beetles (BLB), the expansion of the brown marmorated stink bug (BMSB) in western Kentucky in 2020, and the increased presence of grape colaspis (GC) beetles and three-cornered alfalfa hoppers (TCAH). This proposal will continue evaluating the efficacy of single and double mode of action insecticides for the management of BLB and stink bugs; and the secondary pests cited above. BMSB is an invasive species that has more tolerance to pyrethroids that endemic stink bugs, and the TCAH caused an outbreak in Butler Co. in 2020. Studies will be conducted at the Research and Education Center in Princeton and through visits to at least 4 different commercial fields in Central and Western KY. Also, foliage tissue and beans will be collected from at least ten commercial fields located in several counties that mainly represent soybean acreage in KY. Samples will be collected at least 3 times (V3, R5, and seeds after harvest), all they will be outsourced for virus analysis to determine the infection rates of pod mottle virus. All this information from studies and virus analyses will be summarized and delivered to end users using printed, digital media and in growers and professional meetings.

Project Objectives

1. Assess the impact of insecticide sprays for key (BLB and BMSB) and emerging (Grape colaspis and TCAH) pest during early and late development stages of soybeans in replicate plot tests. 2. Evaluate abundances of insects discussed above in commercial soybean fields and detect the presence of bean pod mottle virus in early and late developmental stages of the plants. 3. Transfer all information generated in this study to end users through the use of digital, printed and extension conferences.

Project Deliverables

Deliver all information obtained in this proposal to different audiences through presentation in local, regional, and national meetings. Publish online/printed articles and videos published in Kentucky Pest News Blog and UKY Soybean newsletter. A peer-reviewed publication after a second year of research. Train a young field applied entomology to an agricultural worker. Report to KSB.

In recent years we have observed a resurgence on the populations of bean leaf beetles (BLB), the expansion of the brown marmorated stink bug (BMSB) in western Kentucky in 2020, and the increased presence of grape colaspis (GC) beetles and three-cornered alfalfa hoppers (TCAH). This proposal will continue evaluating the efficacy of single and double mode of action insecticides for the management of BLB and stink bugs; and the secondary pests cited above. BMSB is an invasive species that has more tolerance to pyrethroids that endemic stink bugs, and the TCAH caused an outbreak in Butler Co. in 2020.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
