  • Title: The development of the endoparasitoid Venturia canescens in Bt-tolerant, immune induced larvae of the flour moth Ephestia kuehniella.
    Author: Rahman MM, Roberts HL, Schmidt O.
    Journal: J Invertebr Pathol; 2004; 87(2-3):129-31. PubMed ID: 15579322.
    Abstract:
    We examined the survival and development of the endoparasitoid Venturia canescens in a Bt-tolerant laboratory strain of the flour moth Ephestia kuehniella, in which Bt-tolerance has been shown to be associated with an inducible elevation of the insect's immune response. The results indicate the elevated immune status associated with Bt-tolerance does not confer cross-protection against parasitism by V. canescens. No significant difference was observed in the rate of emergent wasps from parasitised Bt-tolerant and Bt-susceptible hosts. In addition, wasps from Bt-tolerant hosts had longer development times and were larger than wasps from Bt-susceptible hosts.
