The adaptability of the commercial seeds of silkworm (Bombyx Mori L) on different altitude preservation

Abstract

The selection of silkworm seeds is critical when we are going to start a sericulture business that must be by the environmental conditions, especially the climate. This research aims to look at the response of silkworm seeds which are preserved on two different altitudes from the seed sources in South Sulawesi and Central Java. The seeds preservation, started from hatching eggs to become cocoons, is done at an altitude of 120 meters above sea level (Soppeng Regency) and 700 meters above sea level (Enrekang Regency). Preservation procedures are carried out by the standard operating procedures for maintaining silkworms. The preservation procedure is carried out based on the standard operating procedure for preserving silkworms. The results show that the duration of local C301 PPS seeds is 1.5 - 2 days longer than CRT and C301 CRT BS09 at two different altitude locations. Adaptation of the three seeds based on the hatchability of eggs and the durability of larvae meet the standard commercial seed at different altitude preservation results. The C301 PPS seeds have better solid quality than the other two seeds at two different altitude locations. The cocoons characteristics (shape, color, and texture) and larvae (larvae color and pattern) and relatively the same at two different altitude locations.
