<b>Interaction between natural enemies: <em>Trichogramma</em> and <em>Bacillus thuringiensis</em> in pest control</b> - DOI: 10.4025/actasciagron.v28i2.1101
Abstract
The goal of this work was to detect the possible side-effects provoked by Bacillus thuringiensis (Bt) strains on eggs parasitoids Thichogramma pratissolii and Trichogramma pretiosum. Six strains of Bt: E-3, E-10, E-15, E-16, E-19, and E-20 and Bt kurstaki were assayed in honey drop to stimulate the feeding of the parasitoids in each treatment and offered simultaneously displays with Anagasta kuehniella eggs. The experiment was maintained in a climatized chamber at 25+ 1ºC, RH 70+ 10%, and photophase of 14 hours. The longevity, the daily, the accumulated, and the total parasitism were observed. No treatments affected the longevity of both parasitoids. All treatments in T. pratissolii and E-3, E-10, E-16, and E-19 in T. pretiosum decreased the time necessary to reach 80% of parasitism. The lack of deleterious effects of Bt on these parasitoids suggests that these natural enemies can be used together in IPM programs.Downloads
