Toxicity of Bacillus thuringiensis ß-exotoxin to three species of fruit flies (Diptera : Tephritidae)
Journal of Economic Entomology 92 (5), 1052-1056
Abstract: The current study describes toxic effects of the Bacillus thuringiensis ß-exotoxin toward 3rd instars of 3 fruit fly species: Anastrepha ludens (Loew), A. obliqua (Macquart), and A. serpentina (Wiedemann). The ß-exotoxin was highly toxic to all 3 species tested, with LC₅₀ values calculated as 0.641, 0.512, and 0.408 µg/cm² of filter paper used to expose the larvae, for A. ludens, A. obliqua, and A. serpentina, respectively. Exposure to ß-exotoxin was associated with an increase in the incidence of deformed pupae. The adult survivors from ß-exotoxin treatments showed no negative effects in terms of their longevity, fecundity, or egg eclosion (fertility). We conclude that the ß-exotoxin may have potential as a control agent for fruit fly pests.
