Effects of transgenic Bacillus thuringiensis maize grain on B. thuringiensis-susceptible Plodia interpunctella (Lepidoptera: Pyralidae).
Percentage survivorship, developmental time, adult body length, and sex ratio of Plodia interpunctella (Hübner) reared on field-produced grain from sixteen cultivars of maize, Zea mays L., including several transgenic Bacillus thuringiensis (Bt) Berliner hybrids and selected non-Bt isolines, were evaluated under laboratory conditions. Compared with isolines, development was delayed and survivor...
متن کاملEffects of Two Varieties of Bacillus thuringiensis Maize on the Biology of Plodia interpunctella
On the market since 1996, genetically modified plants expressing an insecticidal toxin (Cry toxin stemmed from Bacillus thuringiensis) target several lepidopteran and coleopteran pests. In this study, we assessed the impact of two varieties of Bt maize producing different toxins (Cry1Ab or Cry1Fa, respectively) on the biology of a storage pest: Plodia interpunctella (Hübner) (Lepidoptera: Pyral...
متن کاملIndividual 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 کاملcDNAs of aminopeptidase-like protein genes from Plodia interpunctella strains with different susceptibilities to Bacillus thuringiensis toxins.
Aminopeptidase N has been reported to be a Bacillus thuringiensis (Bt) Cry1A toxin-binding protein in several lepidopteran insects. cDNAs of aminopeptidase-like proteins from both Bt-susceptible RC688s and Bt-resistant HD198r strains of the Indianmeal moth, Plodia interpunctella, were cloned and sequenced. They contain 3345 and 3358 nucleotides, respectively, and each has a 3048 bp open reading...
متن کاملDevelopment of the larval ovary in the moth, Plodia interpunctella.
The morphogenesis of ovaries and the organization of germ cells within them were visualized during the larval stages of the moth, Plodia interpunctella. The germ cells were observed by utilizing confocal microscopy coupled with immuno-fluorescent staining for the alpha-crystallin protein 25 (alphaCP25). The alphaCP25 was previously shown to be specific to germ cells of pupae and adults, and thi...
متن کاملDifferent mechanisms of resistance to Bacillus thuringiensis toxins in the indianmeal moth.
Susceptibility to protoxin and toxin forms of Cry1Ab and the binding of (125)I-labeled Cry1Ab and Cry1Ac has been examined in three Plodia interpunctella colonies, one susceptible (688(s)) and two resistant (198(r) and Dpl(r)) to Bacillus thuringiensis. Toxicological studies showed that the 198(r) colony was 11-fold more resistant to Cry1Ab protoxin than to Cry1Ab activated toxin, whereas the D...
