| description | The Indian meal moth, Plodia interpunctella (Hübner) is a widespread and serious pest of
stored products. The aim of this study was to evaluate the effectiveness of Bacillus
thuringiensis var. kurstaki, and its synergistic effect with caffeine, in the control of P.
interpunctella. The minimum and maximum lethal concentrations (LC) of B. thuringiensis for
first instar larvae control, respectively were 65 ppm and 7500 ppm. The LC50 for the first instar
stage of larvae was 637.87 ppm. When first instar larvae are fed a diet which contained LC50 of
both B. thuringiensis and caffeine, an increased synergistic interaction in terms of mortality
was found. The mixture of minimum effective concentrations of 65 ppm bacteria and 4000
ppm of caffeine have resulted in 95% mortality after 144 h, whereas caffeine and bacteria alone
caused 10% and 20% mortality, respectively. |
