Viability of Cabralea canjerana extracts to control the South American fruit fly, Anastrepha fraterculus.

Magrini FE, Specht A, Gaio J, Girelli CP, Migues I, Heinzen H, Sartori VC, Cesio V - J. Insect Sci. (2014)

Bottom Line: Ethyl acetate extracts were the most active ones and showed the effect of both dose and time elapses after application on the insects.Low doses caused male abundance, but at higher concentrations the effect was reversed.These encouraging results showed that the C. canjerana extracts have great potential as new tools to be used in integrated pest management programs to protect fruits against A. fraterculus.

Mean percent antifeedant activity on Anastrepha fraterculus adults offered an artificial diet containing extracts in the concentration of 5 mg/mL and choice of (1) fruit ethyl acetate; (2) fruit ethanol; (3) seed ethyl acetate; (4) seed ethanol. High quality figures are available online.

f03_01: Mean percent antifeedant activity on Anastrepha fraterculus adults offered an artificial diet containing extracts in the concentration of 5 mg/mL and choice of (1) fruit ethyl acetate; (2) fruit ethanol; (3) seed ethyl acetate; (4) seed ethanol. High quality figures are available online.

Mentions: Three extracts showed good antifeedant activity towards A. fraterculus adults (Figure 3). The ethyl acetate fruit and seed extracts as well as the ethanolic fruit extract showed 66–57% antifeedant activity, whereas the ethanolic seed extract extracts had a 44% antifeedant activity. This antifeedant effect could be related to the toxicity observed for the ethyl acetate extracts. As the insects died, the antifeedant effect calculation shifts to higher values.
