SILKWORMS (BOMBYX MORI L.) REARING USING ARTIFICIAL DIET DURING THE SUMMER

The purpose of the research is to investigate new methods of silk worms rearing for a longer period during the year. To accomplish our main goal, we used artificial diet for silkworms rearing during the summer. The tasks of our research were to apply an artificial diet from the first to the third instars, and in the fourth and instars we used mulberry leaves. There is a trend showing that the hatchability in September is higher than in July and August. The average values ofthe pupation rate and larval period duration also remained relatively high in September. Considering the fresh cocoon yield by one box of eggs, we found that the lowest values are in August and the highest - in September again. Based on the results obtained, it can he concluded that the rearing of the silkworms using artificial diet in the young instars is most appropriate in September. It is economically viable, leads to greater employment and to increasing of the income of sericulture farmers.
