Testing the potential of entomopathogenic nematodes in attract-and-kill and autodissemination approaches in the control of Queensland fruit fly, Bactrocera tryoni.

ABSTRACT:

Background

Many studies have demonstrated that tephritid fruit fly larvae are highly susceptible to entomopathogenic nematodes (EPNs) and may become infected as they enter the soil to pupate. However, the susceptibility of adult tephritids and their suitability as EPN targets have been less studied. We performed laboratory assays with 12 Australian EPN strains of Heterorhabditis bacteriophora, Heterorhabditis indica and Heterorhabditis zealandica in adults of the Queensland fruit fly, Bactrocera tryoni. Infective juveniles were delivered in a yeast hydrolysate solution that is attractive to flies. We also measured the flight ability of adults up to 3 days after treatment.

Result

Flies that consumed the EPN-yeast preparation experienced 72.8-84% mortality. Between 33.5% and 4
