none Ephestia kuhniella; HYMENOPTERAN-PARASITES; Bracon hebetor; Parasite diapause response to blood diet & photoperiod Bracon hebetor; BLOOD-DIET; Lepidopteran host; DIAPAUSE-; Photoperiod & blood diet from lepidopteran host impact; LEPIDOPTERAN-HOSTS; Ephestia kuhniella; Parasite diapause response to blood diet; PHOTOPERIOD-; Diapause response. Photoperiodic induction of diapause in adults and the influence of diet have been demonstrated. Females of B. nebetor fed in laboratory on either honey or honey and hemolymph of the host (the caterpillars of Ephestia kuhniella). When insects were reared under short-day photoperiods, the hemolymph consumption resulted in a shift of the critical photoperiod by nearly 1 hour and lowered percentage of diapause.
