Abstract:

Investigations of the response of diapausing and nondiapausing (normal) larvae of Plodia interpunclella (Hübner), showed that the diapausing larvae were very sensitive to hydrogen cyanide (HCN), although not differing significantly in toxicity response from the normal larvae. Methyl bromide (MB) was more toxic to normal than to diapausing larvae. HCN depressed overall respiration in both larvae, but MB accelerated CO₂ output of the diapausing form, lending support to the view that the respiration of the diapausing larvae is probably through pathways alternate to the triearboxylic acid cycle.
