With an ultimate aim of producing more and better quantity and quality of silk (a natural protein fiber) and to expand the areas for its production country wise regions, many strains have been introduced date to date.

Abstract Experimental studies have shown that individual wildfowl can shorten or skip moulting if the time between breeding and wintering is short; however, in wild birds are scarce. We tracked nine Common Shelducks Tadorna tadorna during seasons determined flightless based on typical movement patterns. found different patterns for two late-breeding females, suggesting they skipped shortened mo...
The realisation that arthropod moulting and metamorphosis are controlled by juvenile hormones led researches to suggest that such chemicals might be used both against plant pests and animal parasites (Robbins, 1972; Connat, 1988; Dryden, Neal, Bennette, 1989). As the naturally occurring juvenile hormones are unstable compounds in the environment, hundreds of synthetic preparations are prepared ...
