| Abstract: | Queensland fruit fly ('Q-fly'), Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), is the most destructive insect pest of horticultural crops in Australia. The sterile insect technique (SIT) has attracted significant interest for sustainable management of Q-fly through the mass rearing and release of sterile flies. Cost-effective diets are required to rear Q-flies for SIT. Wheat germ oil (WGO) is the main source of fatty acids and vitamins in gel larval diets that are used to rear Q-fly but is an expensive ingredient. With the aim of reducing WGO cost in gel larval diet, we assessed performance of Q-flies reared on diets that varied in WGO content. Q-fly larvae were reared on two diets that differed mainly in yeast composition ('gel diet 2006' and 'gel diet 2009') and contained 0, 0.03, 0.07, 0.11, 0.15, or 1% WGO to identify reduced concentrations of WGO (and hence cost) without compromising productivity or quality. Diets containing WGO outperformed diets without WGO in development rate, pupal number, adult emergence, percentage of fliers, rate of fliers, and fecundity. Concentrations of 0.11% and above provided full benefit in gel diet 2006 (original formulation 0.15%), and concentrations of 0.15% (original formulation 1.0%) and above provided full benefit in gel diet 2009, and for both diets, a concentration-dependent decline in fly performance resulted from lower doses. Savings can be made in gel diets for mass rearing of Q-fly without compromising productivity by reducing WGO concentration. |
