摘要

以前曾在斑马毛虫 Melanchra（原名 Ceramica）picta Harris 的幼虫体内发现过一种杆状病毒。为了进一步确定这种病毒的特征，对两个分离物--Melanchra picta nucleopolyhedrovirus-185（MepiNPV-185）和 MepiNPV-600 进行了全面测序。对基因组序列的分析表明，这两个分离株都属于阿尔法巴库洛病毒（Alphabaculovirus maconfiguratae）种，同时也是柏树军虫（Mamestra configurata Walker）的阿尔法巴库洛病毒（Alphabaculovirus）种。在生物测定中，MepiNPV-600 对黑毛虫（Trichoplusia ni Hübner）幼虫的致病力相对较低。MepiNPV 很可能是由 M. configurata 和 M. picta 幼虫之间的跨种转移产生的，这两种幼虫经常同时出现。

An alphabaculovirus from the zebra caterpillar, Melanchra picta Harris, is an isolate of species Alphabaculovirus maconfiguratae

A baculovirus had been previously identified in larvae of the zebra caterpillar, Melanchra (formerly Ceramica) picta Harris. To further characterize this virus, two isolates, Melanchra picta nucleopolyhedrovirus-185 (MepiNPV-185) and MepiNPV-600, were fully sequenced. Analysis of the genome sequences revealed that both isolates are members of alphabaculovirus species Alphabaculovirus maconfiguratae, along with alphabaculoviruses of the bertha armyworm, Mamestra configurata Walker. MepiNPV-600 displayed relatively low virulence against larvae of Trichoplusia ni Hübner in bioassays compared to other T. ni-pathogenic alphabaculoviruses. MepiNPV likely arose from a cross-species transfer between M. configurata and M. picta larvae, which often occur together.

期刊介绍： The Journal of Invertebrate Pathology presents original research articles and notes on the induction and pathogenesis of diseases of invertebrates, including the suppression of diseases in beneficial species, and the use of diseases in controlling undesirable species. In addition, the journal publishes the results of physiological, morphological, genetic, immunological and ecological studies as related to the etiologic agents of diseases of invertebrates. The Journal of Invertebrate Pathology is the adopted journal of the Society for Invertebrate Pathology, and is available to SIP members at a special reduced price.
