摘要
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。
A biological determination method of insect virus poison was used for determining the poison of Ld PNV in Daiyi County.The results are as follows:LC 50 =1 82×10 4 PIB/ml,the upper limit of 95% confidence is 2 41×10 4 PIB/ml,and the lower limit is 1 22×10 4PIB/ml;when the concentrations of 1 6×10 6 PIB/ml and 1 6×10 5 PIB/ml are used for infection,its LT 50 are 7.38 and 8.24 days respectively.
