Reduced expression of the P-glycoprotein gene PxABCB1 is linked to resistance to Bacillus thuringiensis Cry1Ac toxin in Plutella xylostella (L.).

Pest Management Science, 2020
BACKGROUND Rapid evolution of pest resistance has seriously threatened the sustainable use of Bacillus thuringiensis (Bt). The diamondback moth, Plutella xylostella (L.), is the first pest to develop resistance to Bt biopesticides in the open field ...

Two Pseudogenes of Cotesia plutellae Bracovirus in Parasitized Diamondback Moth, Plutella xylostella

Journal of Asia-Pacific Entomology, 2007
Abstract 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.

Proteomic Analysis of Parasitization by Cotesia plutellae against Diamondback Moth, Plutella xylostella

Journal of Asia-Pacific Entomology, 2005
Abstract Parasitization by an endoparasitoid wasp, Cotesia plutellae, against diamondback moth (DBM), Plutella xylostella, is fostered by maternal and embryonic factors such as polydnavirus, venom, and teratocyte. Genome of C. plutellae bracovirus (‘CpBV’) possessed at least 19 DNA segments, which ranged from 6.8 to over 30 Kb in size and were not ...

CRISPR/Cas9-mediated knockout of both the PxABCC2 and PxABCC3 genes confers high-level resistance to Bacillus thuringiensis Cry1Ac toxin in the diamondback moth, Plutella xylostella (L.).

Insect Biochemistry and Molecular Biology, 2019
Rapid evolution of resistance by insect pests severely jeopardizes the sustainable utilization of biopesticides and transgenic crops that produce insecticidal crystal proteins derived from the entomopathogenic bacterium Bacillus thuringiensis (Bt ...

Identification of key residues of carboxylesterase PxEst-6 involved in pyrethroid metabolism in Plutella xylostella (L.).

Journal of Hazardous Materials, 2020
The long-term and excessive use of insecticides has led to severe environmental problems and the evolution of insecticide resistance in insects. Carboxylesterases (CarEs) are important detoxification enzymes conferring insecticide resistance on insects ...

[Bioactivity of Myoporum bontioides extracts to Plutella xylostella].

Ying yong sheng tai xue bao = The journal of applied ecology, 2006
The 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 ...
