Upregulation of heat shock protein genes by envenomation of ectoparasitoid Bracon hebetor in larval host of Indian meal moth Plodia interpunctella.
Effect of envenomation of ectoparasitoid Bracon hebetor was determined on the heart rate and the expression of shsp, hsc70 and hsp90 of the lepidopteran host Plodia interpunctella. Envenomated host larvae were promptly immobilized but heart rate was not changed until 4 days after envenomation. Northern hybridization showed that each hsp gene was differentially influenced by envenomation: continued high induction of shsp, gradual strong induction of hsc70, but no induction of hsp90. Our results suggest that upregulation of both shsp and hsc70 may produce potent factors that have important roles in the mechanism of host-parasitoid relationship.
