Parasitization by Cotesia plutellae enhances detoxifying enzyme activity in Plutella xylostella
Pesticide Biochemistry and Physiology, 2006Insecticidal tests using diazinon showed that the mortality of Plutella xylostella larvae parasitized by Cotesia plutellae was reduced by 4.6-fold compared to that of the nonparasitized hosts. The use of chemicals with synergistic effect to insecticides in toxicity assay helps to elucidate the kind of enzyme involved in lowering insect mortality ...

Calreticulin in Cotesia plutellae suppresses immune response of Plutella xylostella (L.)
Journal of Asia-Pacific Entomology, 2015Abstract An endoparasitoid wasp, Cotesia plutellae, parasitizes young larvae of the diamondback moth, Plutella xylostella, which is a major pest in cruciferous crops. Successful parasitization requires both maternal and embryonic factors of C. plutellae, such as polydnavirus, ovarian proteins, teratocytes and venom proteins.

Fitness and inheritance of metaflumizone resistance in Plutella xylostella
Pesticide Biochemistry and Physiology, 2017The diamondback moth, Plutella xylostella (L.) has developed resistance to many types of insecticides in the field. To study inheritance and fitness cost of metaflumizone resistance, a susceptible strain of diamondback moth was continuously selected with metaflumizone during 37 generations under laboratory conditions.

Isothiocyanates Stimulating Oviposition by the Diamondback Moth, Plutella xylostella
Journal of Chemical Ecology, 2006Recognition of cabbage as a host plant for the diamondback moth (DBM) has previously been shown to depend on compounds that are extracted by soaking intact foliage in chloroform. Analysis of such chloroform extracts by open column chromatography has now resulted in the isolation of highly active fractions that elicit oviposition on treated filter ...

Genetic control of Plutella xylostella in omics era
Archives of Insect Biochemistry and Physiology, 2019AbstractDiamondback moth, Plutella xylostella (L.), is a specialist pest on cruciferous crops of economic importance. The large‐scale use of chemical insecticides for the control of this insect pest has caused a number of challenges to agro‐ecosystems.

Gut Symbionts Affect Plutella Xylostella (L.) Susceptibility to Chlorantraniliprole
Pesticide Biochemistry and PhysiologyPlutella xylostella, a globally economically important pest of cruciferous crops, has varying degrees of resistance to almost all insecticides. Insect gut microbiotas have a variety of physiological functions, and recent studies have shown that they have some potential connection with insecticide resistance.

Two neem preparations and the bitter-tasting synthetic chemical denatonium benzoate were tested in the laboratory as antifeedants against the diamondback moth, Plutella xylostella L. The effects of the three materials on Cotesia plutellae (Kurdjumov), a hymenopteran parasitoid of P xylostella, were also recorded.
