Enhanced Longevity And Species-Specific Resistance To Malathion Of Adult Mediterranean Fruit-Flies, Melon Flies, And Oriental Fruit-Flies Fed On Diets With Hydrolyzed Protein

Abstract Mortalities of laboratory‐reared adult Mediterranean fruit flies, melon flies, and oriental fruit flies fed hydrolyzed protein were less than those fed whole protein or no protein. Dosage mortalities of these species treated with malathion showed differential toxicities for each species similar to the diet‐specific longevity relationships. Species‐specific sex differences in laboratory mortalities of adult flies were noted: male Mediterranean fruit flies lived longer than females; female melon flies and female oriental fruit flies lived longer than males.
