Individual and Combined Effects of Bacillus Thuringiensis and Azadirachtin on Plodia Interpunctella Hübner (Lepidoptera: Pyralidae)
The Indianmeal moth, Plodia interpunctella Hübner (Lepidoptera: Pyralidae), is a major stored product pest that is found throughout the world. In this study, the effect of oral exposure to Bacillus thuringiensis (Berliner) subsp. kurstaki (Bacillales: Bacillaceae) and azadirachtin was evaluated in third instar P. interpunctella under laboratory conditions. The median lethal concentration (LC50)...
متن کاملPreliminary study on biology and feeding capacity of Chelisoches morio (Fabricius) (Dermaptera:Chelisochidae) on Tirathaba rufivena (Walker)
BACKGROUND Chelisoches morio (Fabricius) (Dermaptera:Chelisochidae) is an important predator of Tirathaba rufivena (Walker) (Lepidoptera:Pyralidae). For better use of the natural enemy, a biological study on C. morio was conducted, particularly its developmental duration, survival, fecundity and sex ratio. And the feeding capacity of C. morio against T. rufivena was also studied under laborator...
متن کاملThe joint action of destruxins and botanical insecticides (rotenone, azadirachtin and paeonolum) against the cotton aphid, Aphis gossypii Glover.
The joint action of destruxins and three botanical insecticides, rotenone (Rot), azadirachtin (Aza) and paeonolum (Pae) against the cotton aphid, Aphis gossypii, was bioassayed. In laboratory experiment, several synergistic groups of destruxins with botanical insecticides were found by means of Sun's Co-toxicity Coefficients (CTC) and Finney's Synergistic Coefficient (SC). The best synergistic ...
متن کاملAnalysis of Host Plant Resistance in Some Genotypes of Maize against Chilo Partellus (swinhoe) (pyralidae: Lepidoptera)
Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...
متن کاملSequential Sampling Plans for Use in Timing Insecticide Applications for Control of European Corn Borer (Lepidoptera: Pyralidae) in Potato
J. Econ.Entomol.89(6): 1468-1476 (1996) ABSTRACT Sequential sampling plans were developed for use in recommending control of European corn borer, Ostrinia nubilalis (Hiibner), in potato, Solanum tuberosum L., fields based on the distribution of damaged stems. Likelihood ratio tests indicated that the betabinomial distribution (aggregated) provided a better fit than the binomial (random) when th...
