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.

f04_01: Sex ratio of flies that emerged from fruits of Carica papaya pulverized with different concentrations of Cabralea canjerana fruits and seed extracts, obtained with ethyl acetate and ethanol, in four distinct periodsHigh quality figures are available online.

Mentions: The different extracts influenced the proportion of individuals of each sex in different ways. Overall, the sex ratio (Figure 4) was skewed. Females prevailed in the treatments using higher concentrations of the extracts obtained with ethyl acetate. Males, by contrast, were more abundant when the ethanolic extract of fruits was used. These effects were kept throughout the 72-hr period.
