Effect of temperature on the development and progeny production of Glyptapanteles muesebecki (Blanchard) (Hymenoptera: Braconidae) parasitizing larvae of Pseudaletia sequax Franclemont (Lepidoptera: Noctuidae) Anais da SEB
Foerster,Luís A.; Avanci,Marion do R.F.; Doetzer,Augusta K..
The developmental time of Glyptapanteles muesebecki (Blanchard) parasitizing the armyworm Pseudaletia sequax Franclemont, and the number of pupae/host were determined at six constant temperatures ranging from 14° to 30°C. The egg + larval stages lasted from 17.8 days at 26° and 29°C to 56.4 days at 14°C, while the pupal stage ranged from 6.4 days at 29°C to 34.5 days at 14°C. G. muesebecki required 291.9 degree-days (DD) above the lower threshold of 8.9°C to complete the egg + larval development, while the pupae required 107.0 DD above 11.1°C. Development from egg to adult was completed after 397.4 DD above the lower threshold of 9.6°C. The number of pupae/host was not significantly different between 18°° and 26°C, and ranged from 86.9 at 22°C to 92.1 at...
