On the Granulosis of Hyphantria cunea DRURY
Japanese journal of applied entomology and zoology, 1969 アメリカシロヒトリの顆粒病の病徴について記載した。顆粒体から分離したウイルス粒子は桿状で300∼350×50∼65mμの大きさであった。罹病幼虫の脂肪組織細胞の細胞質内に顆粒体とウイルス粒子が認められた。顆粒病ウイルスと核多角体病ウイルスの病原性はほぼ同じで,両ウイルスを混合して接種した場合も大差なかった。アメリカシロヒトリの顆粒病ウイルスはカイコ幼虫に対して病原性を示さなかった。

Development of novel betabaculovirus (HycuGV-Hc1) as a biopesticide (HycuGV-TR61) and its efficacy on the fall webworm, Hyphantria cunea Drury (Lepidoptera: Erebidae) larvae [PDF]
, 2023 BackgroundThe aim of this study was to develop an oil formulation from a local betabaculovirus. Hyphantria cunea Drury (Lepidoptera: Erebidae) granulovirus (HycuGV-Hc1) was isolated from the infected larvae to test its efficacy on the pest.

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives
Insect Science, Volume 33, Issue 2, Page 599-617, April 2026.The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects
Insect Science, Volume 33, Issue 2, Page 724-743, April 2026.Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Entomological Research, Volume 56, Issue 4, April 2026.ABSTRACT Pine aphids are notoriously destructive sap‐sucking pests of pine trees worldwide. We investigated the biocontrol efficacy of Bacillus velezensis CE100 through cuticle‐degrading enzymes, which degrade the cuticular structure of insect pests.

Virus Diseases of Hyphantria cunea DRURY
Japanese journal of applied entomology and zoology, 1966 1959年と1965年の第2世代のアメリカシロヒトリに核多角体病の大発生が認められた。多角体の大きさは1∼2μで形は6面体と4面体のものがあった。真皮,脂肪組織,気管皮膜などの細胞核内に多角体が形成された。感染初期の細胞では核の中央部に染色質の塊りがありこの部分に桿状ウイルス粒子(360×30mμ)が多数認められた。核の周辺部ではウイルス粒子は2∼14本の束になっており,これらの束を包みこんだ多角体が散在していた。感染末期には核全体が多角体で充満し,ついには細胞が崩壊した。6面体と4面体の多角体を作るウイルスの間に干渉が認められ,4面体ウイルスの方が6面体ウイルスより増殖速度が早いと考えられた。アメリカシロヒトリの核多角体病ウイルスはカイコ幼虫に対して病原性を示さなかった ...
