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 ...

Proteomic analysis of parasitized Plutella xylostella larvae plasma
Journal of Insect Physiology, 2008Insects use their innate immunity to defend themselves against foreign invaders, such as microorganisms, nematodes and parasites. Cotesia plutellae, an endoparasitoid wasp that parasitizes the diamondback moth Plutella xylostella, uses several strategies to attack the host immune system, such as injection of viruses, venom, and serosal membrane-derived

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.

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.

Function of PxGrp78 in the Reproduction of Plutella xylostella
Archives of Insect Biochemistry and PhysiologyABSTRACTGlucose‐regulated protein 78 (Grp78), a crucial molecular chaperone in the endoplasmic reticulum, has been extensively investigated in vertebrates. However, its functional exploration in insects remains limited. This study cloned the full‐length cDNA sequence of Grp78 in Plutella xylostella (L.), which is 2583 bp long.

[Bioactivity of Myoporum bontioides extracts to Plutella xylostella].
Ying yong sheng tai xue bao = The journal of applied ecology, 2006The bioactivity of Myoporum bontioides extracts to Plutella xylostella was studied with IIPC as evaluated index. The results showed that petroleum ether and chloroform extracts had a higher activity than ethyl acetate and alcohol extracts. At 0.01 gDW x ml(-1), the ODR of petroleum ether and chloroform extracts was 84.69% and 79.90%, and 76.47% and 45 ...

Plutella xylostella (diamondback moth).
2021Abstract The diamondback moth (DBM) is one of the most studied insect pests in the world, yet it is among the 'leaders' of the most difficult pests to control. It was the first crop insect reported to develop resistance to microbial Bacillus thuringiensis insecticides, and has shown resistance to almost every insecticide, including the most ...

The Diamondback Moths : Plutella xylostella and Plutella australiana
Plutella xylostella is the most significant pest of brassicaceous crops worldwide and is estimated to cost up to US$6.9 billion a year in yield losses and management expenses. It is an important pest in Australia where it was recently shown to exist in sympatry with the newly discovered cryptic species, Plutella australiana. P.openaire +3 more sources
Two Pseudogenes of Cotesia plutellae Bracovirus in Parasitized Diamondback Moth, Plutella xylostella
Journal of Asia-Pacific Entomology, 2007Abstract It has been proposed that two novel genes have been found in Cotesia plutellae bracovirus (CpBV) based on the results of a full genome sequencing project. The putative open reading frame (ORF) of CpBV-DBL1 encodes 644 amino acids with one intron, while that of CpBV-DUF1 does 646 amino acids with four introns.
