THE EFFECT OF SCORPION VENOM ON THE MOULTING ACTIVITY OF LARVAE OF THE BEETLE TROGODERMA GRANARIUM

Injection of sublethal doses of venom from the scorpion Leiurus quinquestriatus H. et E. into starved diapausing larvae of Trogoderma granarium results in additional larval moults. When the injected larvae were subjected to diapause‐terminating conditions (leading to pupation) by transfer to test tubes containing fresh food, the injection of venom sharply decreased the number of pupal moults and increased the number of larval moults.
