Plutella xylostella L. is a most serious of insect pest for cruciferous or Brassica crops throughout the world. The common name of this insect pest is the Diamondback Moth (DBM). Plutella xylostella L. is an oligophagous insect which is feed on the group of botanically plants within the single plant family. This insect has become major serious problem to the crops because it easily and rapidly ...

Granuloviruses are widespread pathogens of Plutella xylostella L. (diamondback moth) and potential biopesticides for control of this global insect pest. We report the complete genomes of four Plutella xylostella granulovirus isolates from China, Malaysia, and Taiwan exhibiting pairs of noncoding, homologous repeat regions with significant sequence variation but equivalent length.

The diamondback moth (DBM), Plutella xylostella (L.), costs the Chinese economy US$0.77 billion annually, and considerable research has focused on its biology, ecology, and management. Much of this research has been published locally and is inaccessible outside China. Since 1990 Brassica vegetable production has increased 20-fold and production practices have intensified, but losses continue to...

The genus Plutella was thought to be represented in Australia by a single introduced species, Plutella xylostella (Linnaeus), the diamondback moth. Its status as a major pest of cruciferous crops, and the difficulty in developing control strategies has motivated broad-ranging studies on its biology. Prior genetic work has generally supported the conclusion that populations of this migratory spe...

A proteomic study was conducted to investigate physiological factors affecting feeding behaviour by larvae of the insect, Plutella xylostella, on herbivore-susceptible and herbivore-resistant Arabidopsis thaliana. The leaves of 162 recombinant inbred lines (Rils) were screened to detect genotypes upon which Plutella larvae fed least (P. xylostella-resistant) or most (P. xylostella-susceptible)....

A novel cDNA clong encoding a cytochrome P450 was screened from the insecticide-susceptible strain of Plutella xylostella (L.) (Lepidoptera:Yponomeutidae). The nucleotide sequence of the clone, designated CYP6BF1, was determined. This is the first full-length sequence of the CYP6 family from Plutella xylostella (L.). The cDNA is 1661bp in length and contains an open reading frame from base pair...

Wolbachia spp. are endosymbiotic bacteria that infect around 50% of arthropods and cause a broad range of effects, including manipulating host reproduction. Here, we present the annotated draft genome assembly of Wolbachia strain wAus, which infects Plutella australiana, a cryptic ally of the major Brassica pest Plutella xylostella (diamondback moth).

Insecticide resistance and concomittant field failure to control the diamondback moth (DBM), Plutella xylostella were first recorded in 1968 in Punjab. Studies carried out in different states like Tamil Nadu, Karnataka, Madhya Pradesh, Punjab, indicate that fenvalerate, quilnalphos and monocrotophos resistance are now ubiquitous in Plutella xylostella. In Tamil Nadu, the discriminating dose tec...

The Bacillus thuringiensis subsp. israelensis cytolytic protein Cyt1Aa was found to be toxic to an insecticide-susceptible laboratory population of Plutella xylostella. Cry1Ac-resistant populations of P. xylostella showed various degrees of resistance to Cyt1Aa. Cyt1Aa/Cry1Ac mixtures showed a marked level of synergism in the Cry1Ac-resistant populations.
