- Abstract
Juvenile hormone pesticides can cause chronic poisoning of silkworm (Bombyx mori), causing great economic losses to producing eggs of silkworm. To know whether spraying water in mulberry orchard can reduce the effect of juvenile hormone pesticide on the producing parent eggs of silkworm, mulberry tree was sprayed with water for 30 minutes every afternoon at the degree that the whole plant was wet and all the leaves were dripping water, from the beginning of the grandparent silkworm of F1 hybrid out of the warehouse to the end of cocooning. The 12 strains of grandparent silkworm of F1 hybrid were raised by mulberry leaves picked after spraying water treatment at the beginning of silkworm rearing, and the effects of mulberry leaves fed with water spraying on the body weight, instar course, cocoon formation rate, mating rate and oviposition of Bombyx mori were investigated. Test results indicated that after feeding the mulberry leaves treated with water spraying, the development process, healthy pupa rate, cocoon quality, mating rate and egg quality of the 12 strains of grandparent silkworm of F1 hybrid were affected to different degrees, and the egg quality score and healthy pupa rate were affected obviously. The degree of influence was as follows: Yunxia 4A>Yunxia 4B>Yunkang 1 ZhongA>Yunkang 1 ZhongB>Yunkang 1 Ri B>Haoyue A>Yunxia 3B>Haoyue B>Yunkang 1 Ri A>Yunxia 3A>Jingsong B>Jingsong A. Therefore, in silkworm areas contaminated by juvenile hormone pesticides, producing parent eggs of silkworm in summer with more rain and in autumn with water spraying could reduce the breeding risk of juvenile hormone pesticides and improve the breeding coefficient.
