Chlorpyrifos is a most widely used organophosphate insecticide because of its cost effectiveness and degradable nature. However, this pesticide enters and contaminates the environment either by direct application, spray drifts or crop run off and shows adverse effect on the non-targeted organisms. Philosamia ricini (eri silkworm), one of the most exploited, domesticated and commercialized non m...

objectives: the purpose of current study was to determine the effect of phaleria macrocarpa (p. macrocarpa)fruits aqueous extract on reproductive performance of adult male rats by assessing the serum testosterone level and evaluating their libido behavior. methods and materials: eighteen male adult spraque dawley rats were divided into three groups and designated as treatment (240 mg/kg p. macr...

abstract different responses of silkworm larvae under various rearing climate condition would help to obtain better economic performance of some silkworm varities in specific climate conditions. the effect of 4 rearing climate conditions including 1) standard 2) high temperature and humidity, 3) high temperature and low humidity and 4) temperature fluctuation were investigated on the performanc...

the effect of fungicides on silkworm larvae was analyzed with regard to the fact that these beneficial insects are usually affected by fungicides, daily feeding on 1 and 2g/liter of carbendazim, a systemic fungicide, did not have significant effects on larval and pupal mortality. however the weight of the treated larvae showed considerable weight decrease up to 37% weight.. all the economic tra...

Waste silkworm pupae (SWP) generate vast resources of nutrients for livestock and poultry. In the present investigation, three days old chicks of RIR strain were allocated to five dietary treatments of silk worm pupae meal. The energy budget was prepared from calculated proximate analysis and growth performance of broiler chicks fed with different percentages of silk worm pupae. The result show...

Beyond the commonly known proteins built silk fibres—fibroin and sericin, there are almost 300 bioactive proteins in the silkworm haemolymph. The aim of this work was to present bioactive compounds obtained from the silk fibre and isolated from the body of this insect, which may be used in medical and pharmacological applications. The most important are bioactive proteins. However, the juvenile...

The silkworm infection assay is a useful method for directly evaluating the in vivo therapeutic effects of drug candidates. In the present study, 3 known trichothecenes, trichodermin, epiisororidin E, and verrucarin A, were evaluated as antifungal agents in the silkworm-Candida albicans assay. Trichodermin and epiisororidin E yielded effective therapeutic effects, while verrucarin A exhibited n...
