Two Bacillus thuringiensis(Bt)-resistant strains of the Indianmeal moth, Plodia interpunctella,
lack a major gut proteinase that activates Bt protoxins. The absence of this enzyme is …

Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model
organism for the study of generalized insect development, and an important pest of stored …

The Colorado potato beetle is one of the most challenging agricultural pests to manage. It
has shown a spectacular ability to adapt to a variety of solanaceaeous plants and variable …

To investigate gene expression in Tribolium castaneum exposed to Beauveria bassiana,
reference genes for qPCR were evaluated. Of these, β-actin, α-tubulin, and RPS6 were not …

The microbe Bacillus thuringiensis (Bt) produces crystals that contain insecticidal crystal
proteins (ICPs) used to control many major pests. ICPs are degraded by proteases from a …

Insect resistance to the Cry toxins of Bacillus thuringiensis (Bt) has been examined previously
using a number of traditional biochemical and molecular techniques. In this study, we …

Proteinase activities were compared in soluble and membrane fractions of guts obtained from
larvae of Bacillus thuringiensis-resistant and -susceptible Ostrinia nubilalis. Overall, serine …

Cry toxins produced by the bacterium Bacillus thuringiensis are effective biological
insecticides. Cadherin-like proteins have been reported as functional Cry1A toxin receptors in …

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 (…

Efficient cellulolytic enzymes are needed to degrade recalcitrant plant biomass during ethanol
purification and make lignocellulosic biofuels a cost-effective alternative to fossil fuels. …
