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)....

The glossy cauliflower PI 234599 has been used in breeding programs as a source of resistance to diamondback moth, Plutella xylostella (L.), and other lepidopterous larvae, but the relationship between insect resistance and glossiness has not been clear. One way to clarify this relationship is to find glossy lines carrying different genes for glossiness and test their resistance to insects. In ...

Cinnamoyl amides isolated from Zanthoxylum armatum (Rutaceae) and their synthetic analogues were tested for their insecticidal activity against the second instar larvae of diamondback moth, Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) to determine the promising structures with insecticidal activity. Most of the test compounds showed promising activity against larvae of P. xylostella. H...

Outbreaks of diamondback moth, Plutella xylostella (L.), are being documented more frequently in many regions of the world and the causes for the outbreaks are often associated with insecticide resistance and lack of natural enemies, the latter often due to use of broad-spectrum insecticides. Growers are likely to think of insect management on an individual field basis (i.e. their fields) witho...

Understanding how inbreeding affects fitness is biologically important for conservation and pest management. Despite being a worldwide pest of many economically important cruciferous crops, the influence of inbreeding on diamondback moth, Plutella xylostella (L.), populations is currently unknown. Using age-stage-specific life tables, we quantified the inbreeding effects on fitness-related trai...

Abstract Known as the diamondback moth, Plutella xylostella L. is registered one of most important pests Brassicaceae in world. It characterized a specialized insect this family, due to specifics for feeding. However, based on reports from producers, shoots sour passion fruit extreme south Santa Catarina, were damaged by phytophagous attack. The damage plants collected and this, it was possible...

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).
