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.

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.

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 ...

[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 ...

Improving biocontrol of Plutella xylostella (L.)
2004The workshop on improving biocontrol of Plutella xylostella was held over 2 days during the symposium of the same name held in October 2002 in Montpellier France. Fifty workers from 19 countries participated and formed 5 breakout groups. The backgrounds of the participants were varied.

Abstract An endoparasitic wasp, Cotesia plutellae, inhibits pupal metamorphosis of diamondback moth, Plutella xylostella. The parasitized larvae extended their larval stage about 2 days at 25°C and died after escape of wasp larvae for pupation. We set up a hypothesis that the wasp parasitization inhibits juvenile hormone (JH) degradation, which leads

[Thermal tolerance of diamondback moth Plutella xylostella].
Ying yong sheng tai xue bao = The journal of applied ecology, 2013Diamondback moth Plutella xylostella is a worldwide important pest on cruciferous vegetables. Critical thermal maximum (CTMax) is often used as an index for the thermal tolerance of insects. By the method of dynamic heating, this paper measured the CTMax of P.

Egg parasitoids of Plutella xylostella in South China
2004In South China 5 species of Trichogramma and Trichogrammatoidae parasitoids have been found to attack diamondback moth, Plutella xylostella (L.), (DBM) eggs at an ecological farm where non chemical control measures such as B. thuringiensis and pheromone traps have been used since 1994.
