Abstract

Silkworm rearing has high economical value for producing silk material and other beneficial biological materials such as enzyme, antibacterial agent, and antioxidant. For those purposes, it is important to continuously support high quality feed in the silkworm rearing.This study was aimed to evaluate study the growth of silkworm Bombyx mori fed with artificial diet containing different resources of protein (blood meal or soybean meal). The experiment used completely randomized design 5 five treatments artificial feed formulas and 20 repetitions. Each experiment unit consisted of 1 larvae that was reared individually and given different feed. Formula A: 100% blood meal (BM); B: 75%  (BM) + 25% soybean meal (SM); C: 50% (BM) + 50% (SM); D: 25% (BM)+ 75% (SM); and E: 100% SM. Parameters measured were the feed consumption/larvae, opproximate digestibility, ECI (efficiency of conversion of feed ingested), ECD (efficiency conversion of feed digestibility), and body weight gain in fourth and fifth of the larvae instar. Oxygen consumption were measured on the fifth day of the fifth instar before meal and one hour after meal. The result showed that resource of protein did not significantly affect the parameters on the fourth instar, but significantly affected on the fifth instar larvae. Increment of soybean meal in artificial diet increasing oxygen consumption, and resulted decreassing of ECI and ECD value on the fifth instar larvae.

Abstract

Wild silkworm (Attacus atlas) has high economic value. There is a problem in rearing wild silkworm Attacus atlas, the emergence of males and females imagoes are not the same. The aim of this research was to study the survival lifetime and the sperm of the male imago. This research used randomized design experiment, with two treatments of storage temperature (room temperature 27 °C and cool storage temperature 5 °C) and eight repetitions. Survival of male imago, sperm survival, and imago body weight had been measured. The results showed that cool temperature (5 °C) could to extend significantly (P<0,01) the survival lifetime of male imago and the sperm of male imago A. atlas up to 11.5 ± 0.7 days. There is a positive correlation between body weight and lifetime of male imago of wild silkworm A. atlas, so the lifetime of male imago is predicable from their body weight.
