Total lipid level in parasitized bug, Leptocoris augur, a pest of Kusum tree.

摘要

The lipid contents of the gonads (testes and ovary), muscles and haemolymph of L. augur adults parasitized by Hexamermis vishwakarma were studied. The total lipid content consisted of phospholipids, cholesterol and high density lipoprotein cholesterol. The average lipid contents of parasitized female and male adults after 5, 10 and 15 days of parasitism, and just before the emergence of the nematode were 412.2+or-30.522 and 241.0+or-18.744, 256.5+or-28.893 and 202.1+or-35.473; 194.4+or-36.974 and 116.6+or-19.981, and 116.6+or-26.260 and 132.2+or-22.272 mg/100 ml, respectively. The total lipid contents of the gonads, muscle and haemolymph of parasitized adults were significantly lower than those of the non-parasitized controls. The greatest reduction in lipid content was observed right before the emergence of the parasitic juvenile from the host body.
