The research was conducted to determine Chromium (VI) toxicity in population Bombyx mori. The synthetic wastewater used to irrigate soil to evaluate the impact of pH (4 to 8) at 100 mg/L and initial Chromium (VI) concentrations (25 mg/L to 300 mg/L) at 5 pH in its bioaccumulation in B. mori foodchain.  By using atomic absorption spectrophotometer (AAS) analysis the amount of Chromium (VI) determined in soil, mulberry plants, B. mori larvae, silk glands and silkworm feces. The results showed that local cobalt pollution can be indicated by using B. mori as a template as its body length, body weight and the mortality rate were found to be strongly related to Chromium (VI) concentration. Higher the Chromium (VI) amount in mulberry leaves causes more toxicity to B. mori population. At 300 mg/L Cr (VI) concentration and pH 4 there was maximum deposition of Chromium (VI) in soil, mulberry plants, B. mori larvae, faeces and silk glands from the synthetic effluent. The maximum deposition was 123.5±0.03 mg/kg, 89.76±.031 mg/kg, 23.31±0.019 mg/kg, 41.32±0.069 mg/kg and 35.67±0.04 mg/kg observed respectively.

The effect of quality mulberry leaf Morus cathayana on nutrition index of silkworm Bombyx mori L. have been conducted . This research was Completely Randomized Design (CRD) by two treatments. The first treatment was mulberry plant that cultivated on soil with Urea, TSP and NPK fertilizers and the second was the plants were not fertilized l. Each treatment was replicate 20 times. The results showed that the addition of Urea, TSP and NPK fertilizer on mulberry has effect (p<0,05) on increasing of the growth rate (GR) of instar III, the consumption rate (CR) of instars III and V, and efficiency of conversion of ingested food (ECI) of instar III and V. In addition, approximate digestibility (AD) of instar III, IV were 20%, 7%, 24%, 40% and then V was 51%, 15%, 21% and 70% respectively.

Sericulture is a commerce that involves the cultivation of mulberry plant species, the raising of silkworms, and the manufacture of silk. It is a sustainable, eco-friendly, and agricultural focused commerce. It is one of the largest employment industries, and it has played a significant role in rural opportunities and financial progress. The silkworm is the greatest mulberry assessor since different mulberry   types differ in numerous characteristics. Criteria for assessment have been created using a bioassay of silkworm larvae. The impact of a specific mulberry variety on a certain silkworm hybrid may be assessed based on growth/development, survival, and eventually cocoon generation, which directly influences silk productivity.
