Effects of a commercial neem (Azadirachta indica) extract onStreblote panda larvae



Biological effects of a commercial formulation of azadirachtin, AlignTM, were assessed onStreblote panda Hübner [1820] (Lasiocampidae) first instars by means of choice and nochoice bioassays. Survival, development, and food consumption were recorded. The product tested did not show clear antifeedant effects, but produced dose-dependent larval mortality. All treatments resulted in significant inhibition of growth, presumably through endocrine regulatory effects. At higher doses assayed the product appears to have direct toxic effects. Our results suggest that AlignTM may be used in IPM programs forS. panda and should be evaluated for efficacy under field conditions.
