Objective: The study was conducted to evaluate cardioprotective effect of silk cocoon (Abresham) Bombyx mori (B. mori) on isoprenaline-induced myocardial infarction. This study deals with the cocoons, which is called Abresham in the Unani system of medicine. It is one of the 64 drugs which Avicenna has mentioned in Avicenna’s tract on cardiac drugs and used in the treatment of cardiovascular di...

Reproductive efficiency of economic insects and its rearing performances are greatly affected by hormonal activities together with the environmental and cultural practices. Two different hormones were selected for tropical application on muga silkworm (Antheraea assamensis Helfer) to study their effect on the overall rearing performances. JH-III (Juvenile hormone) in three different concentrati...

The dietary nutritional management influences the rearing and commercial parameters of the silkworm. When silkworms were fed with mulberry leaves fortified with aqueous leaf extract of O. sanctum in the second instar, a positive response with respect to larval and commercial parameters were noticed. Highest larval weight in three instar viz third (1.341g/10 worms),fourth(5.434g/10),while in the...

Silkworm metamorphosis is governed by the intrinsic and extrinsic factors. One key intrinsic factor is the temporal electrical firing of the neuro-secretory cells of the dormant pupae residing inside the silk cocoon membrane (SCM). Extrinsic factors are environmental like temperature, humidity and light. The firing pattern of the cells is a function of the environmental factors that eventually ...
