Alumina powders were synthesized by citrate/nitrate autocombustion method with
different citrate/nitrate molar ratios (0.5, 0.8 and 1.2). XRD analysis of the powders
calcined at 1200 °C for 1 h showed only the presence of α–Al2O3 phase. Particle size of
the powders determined by SEM analysis varied from nano- and submicron size of
several µm. The powders were mixed with grains of bean to examine their insecticide
effect against bean weevil (Acanthoscelides obtectus Say, 1831). Mortality of insects
after seven days of exposure was the highest for the powder synthesized at 1.2 molar
ratio, which contained the highest portion of submicron particles. This suggested that
lager amount of citric acid could prevent higher degree of particles agglomeration.
Mortality cause of insects is assumed to be related to the degree of powder coverage of
the insects’ exoskeleton. The same powder also provided the best efficiency in
suppressing the emerge of F1 generation and seed protection eve...n at lower
concentrations.
