''Lymantria dispar'' multicapsid nuclear polyhedrosis virus or LdMNPV is a well-known and spectacular viral infection of gypsy moths (''Lymantria dispar'') which causes infected larvae to die and disintegrate. Infected larvae climb to the top of the tree during the day and die. The larvae then melt or disintegrate, falling on the foliage below where they infect more larvae. While it possesses many common and technical names, it is often referred to as Gypchek. Gypchek is an insecticide which uses the virus to control the gypsy moth population. Because the virus only infects ''Lymantria dispar'', it has proven safe for use with other insects including ants, bees and non-target lepidopteran species. Studies into its safety have found no toxicity or mortality concerns except for some irritation resulting from ocular doses administered to rabbits. The gene responsible for the behavior of infected larvae has been found to be egt (codes ecdysteroid UDP-glucosyltransferase), with protein tyrosine phosphatase (PTP) playing a role in the infection of brain tissue. Due to the virus's effect on the infected larvae, various reports of 'zombie caterpillars' popularized the virus at the time of the discovery of the egt gene. == Virus name== Since it was first recorded, LdMNPV has been host to numerous common names, taxonomical names, and acronyms. It was first reported in 1891, as 'Wipfelkrankheit'.〔Insect Pathology, Fernando E. Vega, Harry K. Kaya, 2012〕〔(【引用サイトリンク】 title=Wipfelkrankheit : modification of host behaviour during baculoviral infection )〕 Wipfelkrankheit is German for "tree top disease". "Tree top disease" is also used in English,〔 another common term, 'wilt disease' has been in use for over a century.〔 The term 'flacherie', a name which refers to an entirely different disease was once identified as this virus. Another antiquated term, "caterpillar cholera" was also used early in the 20th century.〔 The virus has also been referred to as ''Borralinivirus reprimens''.〔The Gypsy Moth: Research Toward Integrated Pest Management, United States Department of Agriculture, 1981〕 It has many modern names, including 'gypsy moth nucleopolyhedrosis virus',〔(【引用サイトリンク】 title=Gypsy Moth Nucleopolyhedrosis Virus )〕 ''Lymantria dispar'' MNPV,〔 ''Lymantria dispar'' multinucleocapsid nuclear polyhedrosis virus,〔 ''Lymantria dispar'' nuclear polyhedrosis virus,〔 ''Lymantria dispar'' nucleopolyhedrovirus,〔〔(【引用サイトリンク】 title=LdNPV )〕 and ''Lymantria disper'' nuclear polyhedrosis virus,〔 with varying acronyms attached or unattached including LdMNPV,〔 and LdNPV.〔〔 Currently, as by taxonomy, the viral species is known as ''Lymantria dispar'' multicapsid nuclear polyhedrosis virus.〔(Uniprot Taxonomy )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lymantria dispar multicapsid nuclear polyhedrosis virus」の詳細全文を読む スポンサード リンク
