Abstract:Here we report the pathogensis process of Helicoverpa armigera larvae infected with
Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus(HaSNPV)using H.E staining and
immunohistoc hemistry with an tibody against polyhedrin.The fourth instar Helicoverpa armigera larvae ..., Abstract

DNA of Syngraphafalcifera nuclearpolyhedrosis virus D—clone(Sfa-D clone)was extracted
and digested by three kinds of restriction endonuclease.W e calculated its molecular weight an d measure
its melting temperature.G+C% .virus particle an d polyhedrin were purified.The structural ..., Abstract

The polyhedrin gene of the Heliothis armigera single nucleocapsid nucleopolyhedrovirus (HaSNPV) was localized by Southern blot hybridization with a probe from the Autographa cali-fornica MNPV (AcMNPV) polyhedrin gene. Nucleotide sequencing showed the open reading frame of the HaSNPV polyhedrin gene ..., Abstract

MbNPV ,SeNPV and SINPV are important biological agents for three noctuid insects Mamestra brassicae, Spodoptera exigua and Spodoptera litura, respectively. The genomic DNAs from these NPVs were analysed by restriction and dot hybridization. The results showed that they have different restriction ..., Abstract

The polyhedrin gene of Prodenia lituea nuclear polyhedrosis virus(PlNPV) was mapped on the PlNPV DNA HindⅢ-A fragment by Southern-blot hybridization with the AcNPV DNA EeoRI-Ⅰ fragment as probe under 35℃ hybridization conditions. Then, two probes were prepared from PINPV DNA HindⅢ-A and PINPV ..., Abstract

Polyhedra were extracted from the cadavers of Heliothis armigera infected with VHA-273 strain of Heliothis armigera nuclear polyhedrosis virus. Observation under electron microscope showed that the polyhedra consisted of mNPV (90%) and sNPV(10%). The purity of polyhedrin purified by serial ..., Abstract
