In 1977 this nuclear polyhedrosis virus was isolated from the dead larvae of Buzura suppressaria Guenee in the tea garden of "Wang Ling, Hunan. Under ordinary and phase contrast microscopes the polyhedra were seen as nearly rounded, rhombic, trigonal and hexangular particles and 1.2 to 3.6 ft in size. Under the electron microscope, the viron rods liberated from the polyhedra in 0.01 M Na.CO3 and 0.05 NaCl measured 49-63 nm by 251-282 nm. This virus belongs to subgroup A of Baculovirus.Oral administration of the virus on leaves by the larvae of the fourth and fifth instars showed the medium lethal concentration (LC50) to be 10-4.497 (787 PIB) on the fourth day, 10-5.0 (243 PIB) on the nineth day, and 10-6.251 (7 PIB) on the eleventh day. Young larvae were more susceptible to the virus and different routes of virus infection caused different mortality rate.Field test showed the mortality rate of the larvae may reach 98% after spraying with the polyhedral suspension and some infective effect on the later generations may appear.

The granulosis virus from Pieris brassicae ( PbGV ) , having passed in the larvae of Artogeia rapae, was observed under the electron microscope. Its capsules appeared oval or ellipsoidal in shape and were opaque to the electron beam. The virions were rod-shaped, slightly curved. Their envelopes had electron dense material deposited on their outer and inner surfaces. The nucleocapsids were rod-shaped, too, but not curved. The sizes of the capsules, virions and nucleocapsids were 335 - 398 × 219 - 259nm, 221 -...

The granulosis virus from Pieris brassicae ( PbGV ) , having passed in the larvae of Artogeia rapae, was observed under the electron microscope. Its capsules appeared oval or ellipsoidal in shape and were opaque to the electron beam. The virions were rod-shaped, slightly curved. Their envelopes had electron dense material deposited on their outer and inner surfaces. The nucleocapsids were rod-shaped, too, but not curved. The sizes of the capsules, virions and nucleocapsids were 335 - 398 × 219 - 259nm, 221 - 260 × 65-75nm and 245 - 283 × 51 - 62nm respectively.When PbGV was fed orally to the newly hatched larvae of Artogeia rapae, its median lethal concentration ( LC50 ) was 1.22 × 103GIB/ml. The median lethal time ( LT50 ) of the GV was shortened with the increase of the virus concentration and the decrease of the larval instar, during which the GV was fed. The most favorable temperature for the GV infection was about 25-30℃. In this temperature range, the LT50 was shortened obviously.These results have guiding significance in the application of PbGV in the biological control of Artogeia rapae and the mass multiplication of PbGV using the larvae of Artogeia rapae as the target organism.

经菜粉蝶幼虫增殖的大菜粉蝶颗粒体病毒(PbGV),其包涵体为卵圆至椭圆形颗粒,不易为电子束所透射;病毒粒子略呈杆状,稍弯曲,脂膜内外有电子致密物质沉积;核衣壳杆状,较直。病毒包涵体、病毒粒子和核衣壳的大小分别为335-398×219-259nm、221-260×65-75nm和245-283×51-62nm。 PbGV包涵体经口喂饲菜粉蝶初孵幼虫,其致死中浓度(LC_(50))为1.22×10~3GIB/ml。幼虫饲毒后,致死中时(LT_(50))随病毒浓度提高而缩短;随饲毒时虫龄的增大而延长。病毒感染寄主幼虫的最适温度约为25~30℃,在此温度范围内,LT_(50)明显缩短。
