摘要
１９８５年从四川省珙县某茶场自然罹病死亡的茶刺蛾幼虫中分离到一种颗粒体病毒，该病毒为杆状，大小为２８１ｎｍ×７３．５ｎｍ，对茶刺蛾幼虫具较强的感染力，对３龄茶刺蛾幼虫的ＬＤ５０为２．６３×１０＾４ＧＢ。该病毒专一性强，用１０＾６ＧＢ／ｍｌ，的茶刺蛾颗粒体病毒防治４龄茶刺蛾幼虫的防治效果达９０％以上。
A strain of granulosis virus (DtGV) was collected in 1985 from dead nettle caterpillars (Darna trima Moore) naturally infected by virus in a tea plantation in Gongxian County, Sichuan Province. Its particle is baculiform, 281nm×73. 5nm of size, located individually in the center of each elliptic or oval inclusion body with 296nm×130nm of size. DtGV is highly infections and of high specificity to D. trima larvae, its LD50 for 3rd instar larvae was 2. 63×104 GB. 90% of control result was obtained after spraying 106GB/ml of DtGV on 4th instar larvae.
