TEMPERATURE DEPENDENT DEVELOPMENT RATES OF PARASITOID, HABROBRACON HEBETOR, DIRECTLY FED ON BACILLUS THURINGIENSIS VAR. KURSTAKI

The interaction of temperature and directly ingested Bacillus thuringiensis (Bt), on the developmental rates of the parasitoid Habrobracon hebetor progeny was investigated using Corcyra cephalonica 4th instar larvae as host. Development rates increased with temperature rise. Regression analysis revealed highly significant (p .05) was not a good fit of the equation. Although r- values were overall lower and regression showed no significant fit of the equation for larval periods, significantly higher development rate was observed towards higher temperatures. However, rates during pupal period and total lifecycle showed highly significant (p
