Herbivore range expansion triggers adaptation in a subsequently-associated third trophic level species and shared microbial symbionts

Scientific Reports, 2019
Invasive species may change the life history strategies, distribution, genetic configuration and trophic interactions of native species. The diamondback moth, Plutella xylostella L., is an invasive herbivore attacking cultivated and wild brassica plants ...

Conjugative Transfer of Disease‐Encoding Plasmid Variants in Serratia spp. Alter Production of Enzymes and Virulence Properties

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Analysis of plasmid transconjugants relative to plasmid‐free and plasmid‐carrying Serratia spp. demonstrates erratic disease phenotypes and reduced fitness. Transconjugants also show reduced ability to degrade substrates associated with virulence, supported by transcriptomic data.

Report of the parasitoid wasp, Cotesia plutellae (Hym.: Braconidae), from Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2008
This paper reports the occurrence of the hymenoterous parasitoid of the diamondback moth larvae in Iran. One species of Braconidae, Cotesia plutellae (Kurdjumov), was collected from larvae of Plutella xylostella (L.) (Lep.: Plutellidae). This parasitoid,

Cecropins from Plutella xylostella and Their Interaction with Metarhizium anisopliae

PLOS ONE, 2015
Cecropins are the most potent induced peptides to resist invading microorganisms. In the present study, two full length cDNA encoding cecropin2 (Px-cec2) and cecropin3 (Px-cec3) were obtained from P. xylostella by integrated analysis of genome and transcriptome data.

Protogyny in Diamondback Moth, Plutella xylostella (Lepidoptera: Yponomeutidae).

Japanese journal of applied entomology and zoology, 1997
農家のキャベツ圃場で採集したコナガの蛹を20°Cの恒温器内で羽化させ,雌雄の羽化消長を比較した。雌の蛹の羽化までに要した日数の中央値は雄の蛹のそれより1∼2日小さかった。15°C, 20°Cおよび25°Cの三つの恒温条件下でキャベツを餌として120頭ずつ個体飼育し,雌雄の発育の経過を比較した。卵期および幼虫期には雌雄差は認められなかったが,蛹期には雌雄差が認められた。この結果,卵∼羽化までの発育期間には雌雄差が認められた。11月10日(第1グループ)と11月30日(第2グループ)に産下されたコナガの卵を圃場内の百葉箱内で個体飼育したところ,第1のグループは1月5日∼1月18日に,第2のグループは2月13日∼2月27日に羽化した ...
