Effect of feeding mulberry silkworms with leaves of different cultivars and hybrids on silk gland activity and yield of cultivated cocoons

Abstract

During the agrotechnics of mulberry silkworm care by farms, clusters and specialized farms engaged in cocooning in our country, the nutritious feed given to the mulberry silkworm during its youth is used in the season of medicating agricultural crops. The purpose of the research was to investigate the causes of mulberry silkworm diseases resulting from poisoning in several districts of the Tashkent region, including Orta Chirchik, Lower Chirchik, Piskent, Yangiyol, Chinoz, Bostanliq, and Ohangaron. The results showed that the weight and volume of the silk gland were higher in the experimental variants, ranging from 1550-1650 mg and 1.55-1.63 cm3, respectively, compared to the comparative variant, where the weight and volume were 1470-1480 mg and 1.45-1.48 cm3, respectively. The difference in weight and volume was found to be 6.9-11.5% and 6.5-10.1%, respectively, lower than the experimental variants.
