| Abstract: | 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, 281 nm×73.5 nm of size, located individually in the center of each elliptic or oval inclusion body with 296 nm×130 nm 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 106 GB/ml of DtGV on 4th instar larvae. |
