Alumina powders were obtained by auto combustion method and calcined for 1 h at
temperatures ranging from 1000ºC to 1200ºC. X-ray powder diffraction analysis revealed an
overwhelming presence of γ–Al2O3 for the powder calcined at 1000ºC, while at 1200ºC only
the presence of α–Al2O3 was detected. Insecticide properties of these powders were
investigated on bean weevil (Acanthoscelides obtectus Say). Mortality of treated and
untreated male and female adults was checked in a period of 7 days. The powder calcined at
1200ºC was the most efficient, and 100% mortality of both male and female insects were
reached after 7 days of exposure. It was also observed that insecticide efficiency increased
with the increase of α–Al2O3 phase present in the powders and the female insects were less
susceptible to the powders’ toxicity in general. Scanning electron microscope analysis of the
treated adults with Al2O3 indicated that mortality of bean weevils can be related to adsorption
of the pow...ders onto their exoskeleton. Development of F1 progeny was similar for all the
powders and the number of hatched larvae was significantly reduced in comparison with the
untreated seeds, while the percentage of damaged seeds dropped from 70% to 15%. These
results suggest that relatively cheap and non-toxic α–Al2O3 powders can be considered for use
in pest control, especially in organic seed production
