The results on determining the mode of suitable brushing-rearing silkworm in technological process “rear and product F1 level variety of silkworm”.
Curently, in the production of sericultural, requirement of F2 level seed eggs for sericultural production is high. To satisfy the requirement of F2 level seed egg production, the quantity of F1 level silkworm reared per stage is quite much. Meanwhile the rearing establishment and F1 level seed egg multiplication establishment in whole country still rear silkworm following the process: Brush of hatched larvae and rear silkworm in single egg brood. This courses higher in cost of rearing silkworm. It is not only waste of labour and material but also decrease effective economy of rearing silkworm. The results of research determined that the mode of brushing-rearing silkworm by 2 egg broods per pile will bring the highest effective economy. The economic and technical target is approximate the formula control (brusing-rearing silkworm by single egg brood). This mode saved 99,500 - 141,500 VND per egg brood on lobour and mulberry leaves.
