摘要
添加萤光素钠、６５６Ｌ乳化剂等的ＥｐＮＰＶ制剂，其四号和五号配方对茶毛虫的ＬＣ＿７０分别为４．４２×１０￣５ＰＩＢ／ｍｌ和１．７５×１０￣６ＰＩＢ／ｍｌ，与同浓度病毒悬液比，毒力系数（１）分别为４．３９和１．１１；用五号配方５～６×１０￣７ＰＩＢ／ｍｌ可比同浓度ＮＰＶ悬液提高防效１１．２％，在７００ｈａ茶园应用平均防效达８０％以上，经济效益１３０５元／ｈａ；安全性检测表明，对人畜均安全无害。
The Nuclear Polyhedrosis Virus(NPV)preparation of No. 4 and No. 5 formulae added with fluorescein sodium. 656L emulsifier for controlling the larvae of teatussock moth Euproclis pseudoconspersa was made. The contents of LC_70 in them are 4.42×10￣5 PIB/ml and 1.75×10￣6 PIB/ml. and the toxic coefficients are 4.39 and 1.11 respectively. The control effect on the larvae of tea tussock moth is improved with 11.2% by using the No. 5 preparation of 5- 6×10￣7 PIB/ml compared with NPV suspension at the sameconcentration. The economic benefit is 1305 yuan/ha. The determination of security showedthat the preparation is harmless for man and animal.
