Larval survival and development of susceptible and resistant Ostrinia nubilalis (Lepidoptera: Pyralidae) on diet containing Bacillus thuringiensis
Agricultural and Forest Entomology 7 (1), 45-52
Abstract: 1 - Larval survival and development of Dipel-susceptible and -resistant strains of European corn borer, Ostrinia nubilalis (Hübner), were assayed using diets incorporating low doses of a commercial formulation of Bacillus thuringiensis var. kurstaki Berliner (Dipel ES).
2 - Larval mortality, growth and development, pupation rate and pupal weight were not significantly different between Dipel-susceptible and -resistant strains when larvae were reared on a nontoxic control diet.
3 - Larval mortality of Dipel-resistant larvae did not significantly change as Dipel concentration increased at the tested concentrations, whereas mortality of Dipel-susceptible larvae increased dramatically as Dipel concentration increased.
4 - Larval development was significantly delayed when larvae were fed diets containing low doses of Dipel.
5 - Pupation rate and pupal body weight declined as Dipel concentration increased but it decreased faster for the susceptible strain than for the resistant strain.
