Abstract

The organic constituents of haemolymph (proteins, carbohydrates) play an important role in biochemical processes underlying growth and development of insects. The biochemical parameters and activity of enzymes was estimated in haemolymph of silkworm, B. mori from first day to sixth day of fifth instar which were fed with mulberry leaves treated with pesticides. The total protein content in haemolymph was found significantly decreased in pesticide treatments from first day to sixth day of fifth instar. The total carbohydrate content in the haemolymph was found significantly increased from first day to sixth day in all the treatments. The results indicated that, novluron 10EC and chlorfenapyr 10SC were highly toxic even after waiting period

Keywords

Silkworm, haemolymph, protein, carbohydrate, pesticides, novluron

Conclusion

The study revealed that pesticide exposure significantly decreases total protein content while increasing total carbohydrate content in the haemolymph of silkworms. Treatments with carbofuron, dimethoate, novluron, azadirachtin, fenazaquin, dinotefuron, and chlorfenapyr notably reduced protein levels, whereas carbohydrate levels were elevated across all treatments
