Survey For Spotted-Wing Drosophila (Diptera: Drosophilidae) In The Five-County Nursery Production Region Of Middle Tennessee, Usa, Karla M. Addesso, Jason B. Oliver, Paul A. O'Neal

Agricultural and Environmental Sciences Faculty Research

Through global trade, spotted-wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), a native of Southeast Asia, has spread to at least 3 other continents since 2008. Initial reports of the fly in new regions often are associated with damage in agriculture fields, but the fly may be present in the landscape for years before populations reach a level at which they become a pest in fruit production. In 2012, spotted wing drosophila was reported in blueberry fields in eastern Tennessee, USA, for the first time. In order to determine whether the fly was established in middle Tennessee, we conducted landscape surveys …

Evaluation Of Disinfectants To Prevent Mechanical Transmission Of Viruses And A Viroid In Greenhouse Tomato Production, Rugang Li, Fulya Baysal-Gurel, Zaid Abdo, Sally A. Miller, Kai-Shu Ling

Agricultural and Environmental Sciences Faculty Research

Background

In recent years, a number of serious disease outbreaks caused by viruses and viroids on greenhouse tomatoes in North America have resulted in significant economic losses to growers. The objectives of this study were to evaluate the effectiveness of commercial disinfectants against mechanical transmission of these pathogens, and to select disinfectants with broad spectrum reactivity to control general virus and viroid diseases in greenhouse tomato production.

Methods

A total of 16 disinfectants were evaluated against Pepino mosaic virus (PepMV), Potato spindle tuber viroid (PSTVd), Tomato mosaic virus (ToMV), and Tobacco mosaic virus (TMV). The efficacy of each disinfectant to …
