Toxicological evaluation of some botanical oils on biochemical aspects in the Indian meal moth Plodia interpunctella HB. (Lepidoptera: Pyralidae)

Abstract

The biochemical changes in the haemolymph of Plodia interpunctella larvae treated with sublethal concentrations of two volatile oils and three fixed oils were studied. All oil treatments increased the levels of haemolymph lipids and protein but decreased their carbohydrate contents. However, electrophoretic assays on the haemolymph of the treated larvae revealed the presence of additional protein patterns due to oil treatments. The metabolic features of both oils are considered having juvenilizing action, where some morphogenetic abnormalities in treated larvae as well as developed pupae and adults were observed.

KEY WORDS: Plodia interpunctella, biochemistry, morphogenetic
