采用昆虫病毒毒力生物测定方法［１］，以舞毒蛾 ２ 龄幼虫为对象，对大邑株舞毒蛾核型多角体病毒毒力进行测定，其 Ｌ Ｃ５０ ＝ １８２×１０４ Ｐ Ｉ Ｂ／ｍ ｌ，９５％ 置信限上限为 ２４１×１０４ Ｐ Ｉ Ｂ／ｍ ｌ，下限为 １２２×１０４ Ｐ Ｉ Ｂ／ｍ ｌ；用浓度 １６×１０６ Ｐ Ｉ Ｂ／ｍ ｌ 和 １６×１０５ Ｐ Ｉ Ｂ／ｍ ｌ 进行感染， 其 Ｌ Ｔ５０分别为 ７３８ 天、８２４ 天。
The virulence of the Gypsy moth nuclear polyhedrosis virus in Dayi was determined by the virulence bioassay of insects [1]. The second instar larvae of Gypsy moth were used to determine the virulence of the Gypsy moth nuclear polyhedrosis virus. The L C50 was 1.82 × 104 P I B / m l, the upper 95% confidence limit is 241 × 104 P I B / m l, the lower limit is 1 2 2 × 104 P I B / m l; 6 × 105PIB / ml infection, the L T50 were 7 38 days, 8 24 days.
