Abstract
The Oak tsar silkworm, Antheraea proylei is an economically importantinsect. This silkworm and its host plant have become prone to attack ofnumerous pests, predators and microbial diseases. In order to procurehealthy cocoon and better yield, it needs to be protected. The lipid contentin the healthy full grown larval haemolymph, silk glands and food leaves of Antheraea proylei Jolly has been determined by extraction withchloroform and methanol following a standard method. The lipid contentin the larval haemolymph varies from 65.69 to 67.21 mg/ml with a meanvalue of 66.54+0.151 and 0.1430 to 0.1436 mg/mg fresh weight in the silkglands with a mean value of 0.1433+0.00006. While the lipidcontent in the food leaves, Quercus serrata ranges from 0.0232 to 0.0264mg/mg dry weight with a mean value of 0.0249+0.00038. The multiple correlation coefficient of silkglands on haemolymph and food leaves was found to be R²= 72.0% and significant at 5% level.
