1980年10月在安徽省舒城县采集茶蚕虫尸,分离出一株茶蚕颗粒体病毒。小区试验及大面积防治示范表明:茶蚕颗粒体病毒防治茶蚕,致病死亡速度与气温密切相关;防效不受夏季较高气温影响,而受秋季较低气温影响;每亩剂量为100—200mg,气温低于20℃以200mg为宜;对各代虫体均有较好防治效果,为75.5—97.5％;防治适期以卵盛孵期至2龄前幼虫为宜。气温低于20℃时,病毒与低剂量杀虫双混用有明显的增效作用,增效18.8％,缩短死亡期6天,病毒对天敌安全,后效作用明显,1—3年内,感病死亡率为40—56.4％。
October 1980 in Shucheng County, Anhui Province collected tea silkworm worm, isolated from a tea silkworm virus. Community trials and large area prevention and control demonstration showed that: Tea silkworm particles prevent and cure tea silkworm, pathogenic death rate and temperature are closely related; control effect is not affected by the higher summer temperatures, but by the lower temperature in autumn; the dose per acre 100 -200mg, the temperature is below 20 ℃ to 200mg is appropriate; generations of parasites have better control effect, 75.5-97.5%; When the temperature is lower than 20 ℃, the synergistic effect between the virus and the low-dose insecticidal double-mixed is obvious, with a synergistic effect of 18.8% and a shortened death period of 6 days. The virus is safe to natural enemies and the aftereffect is obvious. Within 1 to 3 years, The mortality rate is 40-56.4%.
