摘要
蜀柏毒蛾Parocneria orienta Chao是柏木的一种重要害虫。1988年笔者在福建南平室内饲养和野外调查时,发现蜀柏毒蛾幼虫自然罹病死亡,经鉴定其病原为一种核型多角体病毒。该病毒尚未见报道,现将其分离、电镜观察、生物活性测定等报道如下。
In 1988, a nuclear polyhedrosis virus of Parocneria orienta Chao was isolated in Nanping, Fujian Province, China,by scanning electron microscopy. It was shown that the inclusion body was a hexahedron, with a diameter of 0.61-2.69 μm. The virus was singly embedded rod-shaped, with a size of 48—72×320—376 nm. The LC50 values for early second-instar to fifth-instar larvae were 5.455 × 10~4, 2.036×10~5 2.933 × 10~5 and 1.438 × 10~6 PIB/ml, respectively. The LT50 decreased with the increasing virus concentration.
