Trapping and development of degree day model for Missouri Berry Crops
Spotted wing drosophila (Drosophila suzukii Matsumura) is an important pest of berry crops like strawberry, brambles (raspberry, blackberry, others), elderberry, blueberry, cranberry (including lingonberry), and Ribes (currant and gooseberry). The insect is important because, unlike other drosophilids, it can directly damage soft fruit crops by laying its eggs in the berries and fruits that can go undetected during its initial damage. Degree-day models have been incorporated in the successful management of many key pests of small and tree fruits such as codling moth (Borchert et al. 2004, Jones et al. 2013), plum curculio (Akotsen-Mensah et al. 2011), and brown marmorated stink bugs (Nielsen et al. 2008, 2016), but this has not been done for SWD in Missouri. A trap-based predictive model is an important pest management tool that could be used to detect and predict SWD early activity in the field to help in the timely application of insecticides (Drummond et al. 2019, Kamiyama et al. 2020). The phenology and seasonal patterns of SWD were investigated during 2021-2022 in several research and grower farms in Missouri. A relationship between trap numbers and degree day accumulation during the period was examined using logistic and Weibull functions to predict the activity of SWD. The results showed a logistic function as a better predicting function for the SWD phenology. The results are discussed based on the reliability of the model in predicting SWD seasonal activities.

Speakers

Clement Akotsen-Mensah
State Extension Specialist-IPM @Lincoln University
Dr. Clement Akotsen-Mensah is the State IPM specialist at Lincoln University Cooperative Extension and Research of the College of Agriculture, Environmental and Human Sciences. He has a Ph.D. (2010) in Entomology from the Department of Entomology and Plant Pathology, Auburn University, Alabama. His main research is to develop Integrated Pest Management solutions, particularly, for small-scale farmers in Missouri. His research uses different approaches to identify and evaluate traps and attractants for pest monitoring, use of trap crops to manipulate insect behavior, develop predictive models, screen insecticide and integrate different tactics for major pests of agricultural importance. He has broad understanding of IPM tactics utilized across multiple cropping systems demonstrating his ability to conduct and translate research concepts and findings to varied stakeholder groups.
Caroline Foba
Extension Associate @Lincoln University
Dr. Foba is an Extension Associate for Integrated Pest Management (IPM) at Lincoln University, Missouri. She assists the State Extension Specialist in conducting basic and applied research on system-level IPM tactics for small scale, limited-resource, and socially underprivileged vegetables and small fruit growers in Missouri. She also assists in developing and disseminating new information to growers and other stakeholders. Additionally, Foba assists in teaching and supervision of students, writing and editing of grants, peer-reviewed articles, guide sheets, and facts sheets, and preparing posters and presentations for events. Foba has a keen interest in agricultural research and extension which is crucial for sustainable global food security. She is open to people who can inspire and challenge her to reach her professional goals.
