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.

insects-05-00488-f005: Impact of dipping infested berries in entomopathogenic nematodes and fungi on resulting fruit fly emergence following 10 days incubation at 25 °C. Total numbers from 44 berries per treatment.

Mentions: Both the nematodes and fungi would appear to cause population decreases of D. suzukii (Figure 5). However, neither would seem to have the potential to eradicate D. suzukii. There was no marked impact on fly emergence, with populations developing as normal (Figure 5). There was no significant difference between the individual control agents or the water control (p > 0.05).
