Quantitative estimation of total cholesterol level in different tissue of parasitized bug, Leptocoris augur Fabr, a pest of Kusum tree, Schleichera oleosa lour


Kumkum

Leptocoris augur is a pest of kusum plant (Schleichera oleosa), which in turn is a host of lac insect. The bug is parasitized by a mermithid nematode, Hexamermis vishwakarma, which naturally checks rapid built-up of bug population. The present work reports the results of cholesterol content in different tissue such as Gonads (i.e., testes and ovaries), muscles and haemolymph of parasitized bugs. The total extracted cholesterol was estimated by the method of Annino (1976) and Frings, etal, (1972). The concentration of total cholesterol in control bug (L. augur) was very high in the haemolymph as compared to that of the parasitized bugs. The cholesterol content of fat body and muscles of L. augur (host) was diminished by H. vishwakarma infections. This increasing trend in cholesterol level was observed before the emergence of parasitic juvenile from the host body in female and male bugs. The cholesterol level in haemolymph increased by the mermithid parasitism in reproductive organs of both the sexes. But, in gonads the average level of cholesterol was also found to be depleted as the parasitism advances as compared to control one.
