Evaluation of Select Ornamental and Small-Fruit Plants for Host-Suitability of the Spotted-Wing Drosophia (Swd)
Southern Horticultural Research
2013 Annual Report
1a.Objectives (from AD-416):
The objective of this cooperative research is to conduct life-history analysis of the new and invasive insect pest, the Spotted-Wing Drosophila (SWD) to determine if key ornamental and small-fruits grown in the southern USA may be susceptible to economic damage.
1b.Approach (from AD-416):
A variety of locally grown, common ornamental species will be examined to determine if Spotted-Wing Drosophila (SWD) is causing damage to plant structures. In particular, dogwoods, roses, and other common small-fruit species grown (esp. blue berry cultivars) in the Tennessee Valley will be examined. Adult monitoring traps will be deployed to determine if and when SWD are present in a given area. If SWD is detected, then standard life-history analysis will be performed for the infected plant(s). Special emphasis will be to determine if the infected host is a suitable reproductive host for SWD.
This project is currently just beginning. A PhD graduate student has been identified at Tennessee State University (TSU) to work on this SCA. The student has made visits to the ARS laboratory in Poplarville, MS and the Priciple Investigator (PI)is in monthly contact with the TSU professor via phone and email conversations.
