Preliminary Screening of Potential Control Products against Drosophila suzukii.

Cuthbertson AG, Collins DA, Blackburn LF, Audsley N, Bell HA - Insects (2014)

Bottom Line: Highest mortality (68%) was achieved following direct application of TA2674.Entomopathogenic agents (nematodes and fungi) tested appeared to reduce fly population development (ranges of 34-44% mortality obtained) but would seem unable to eradicate outbreaks.The potential of the tested products to control D. suzukii is discussed.

ABSTRACT
The first recording of Drosophila suzukii in the UK occurred in the south of England during August 2012. Since then sticky traps have continued to record the presence of individuals. Several products (both chemical and biological) were investigated for their efficacy against different life-stages of the pest. Both direct and indirect exposure to control products was assessed. Spinosad, chlorantraniliprole and the experimental product, TA2674, showed excellent potential as control agents when used as either a pre- or post-dipping treatment for blueberries with mortalities of 100%, 93% and 98% mortality, respectively, being achieved following pre-treatment. Direct spray application of all products tested had limited impact upon adult flies. Highest mortality (68%) was achieved following direct application of TA2674. Entomopathogenic agents (nematodes and fungi) tested appeared to reduce fly population development (ranges of 34-44% mortality obtained) but would seem unable to eradicate outbreaks. The potential of the tested products to control D. suzukii is discussed.

Mentions: Drosophila suzukii used in the experiments originated from wild specimens from Northern Italy, collected in the autumn of 2012. Specimens were imported into the UK under a specific license required for importing non-indigenous invertebrates [13]. A colony was initiated within the secure Insect Quarantine Unit at the Food and Environment Research Agency, York, within bug-dorm (280 mm × 280 mm × 280 mm; Watkins and Doncaster, Leominster, UK) insect cages at 25 °C, 65% r.h. and 16:8 h L:D regime (Figure 2). The insects were maintained on a mixture of Drosophila diet (Blades Biological, Cowden, UK) and organic blueberries (Figure 3A–C).
