Effect of nutritional supplements treated Quercus serrata leaves on life cycle and economic traits of oak tasar silkworm (Antheraea proylei)

Devi S, Ankita, Poonam and Rana A

The experiment entitled “Effect of nutritional supplements treated Quercus serrata leaves on life cycle and economic traits of Oak tasar silkworm (Antheraea proylei)” was conducted during April 2024 to June 2024 at experiential site, Central Research and Training Institute, Chauntra, district Mandi, Himachal Pradesh with the objectives viz., to study the effect of nutritional supplements treated Q. serrata leaves on life cycle, growth parameters and economic traits of oak tasar silkworm (A. proylei). Three types of artificial diets; Artificial diet1 (vitamin C - complex @ 1%), Artificial diet2 (protein @ 1%), Artificial diet3 (vitamin B - complex @ 1%) and fourth was the control (natural diet) were used for rearing of Oak tasar silkworm (A. cnproylei). Formulated diets were compared with natural diet and the observations on life cycle, growth parameters and economic traits were recorded. The study revealed that amongst the three formulated artificial diets, artificial diet2 (Q. serrata leaves treated with protein @ 1%) was found to be promising for all the five larval stages of silkworm and selected for further studies. Life cycle parameter of instar like larval duration (46.44 days), pupal duration (12.75 days), moth emergence (94.11%) and growth parameters like larval length (87.84 mm), larval breadth (188.26 mm), larval weight (21.28 g), cocoon weight(6.99 g) as well as economic traits like silk filament length (1164.28m) were significantly maximum in T2 treatment (Q. serrata leaves treated with protein @ 1%) followed by T1treatment (vitamin C - complex @ 1%) and T3 treatment (vitamin B - complex @ 1%). The lowest larval duration, pupal duration, larval length and breadth in fifth instar larvae ((39.16 days, 9.20 days, 84.22 mm and 18.56 mm, respectively) was recorded in untreated control. Lowest larval weight (17.08 g) and silk filament length (891.78 m) in fifth instar was also observed in larvae feeding on untreated Q. serrata leaves.
