The reproductive traits of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) were investigated and analyzed by different analytical methods. Simple statistical analysis showed relatively higher mating rates maintained from 21:00 to 2:00, thereafter dropping to a minimum at about 18:00. Mating rates were affected by female and male age. Mating was most likely to take plac...

Environ. Entomol. 19(5): 1566-1571 (1990) ABSTRACT The dispersal and survival of neonate diamondback moth larvae, Plutella xylostella (L.), were measured on normal bloom susceptible 'Round-Up' cabbage and a resistant genotype descended from glossy cauliflower, PI 234599. During the first 24 h after hatching, neonate P. xylostella dispersed more rapidly and initiated fewer mines on the resistant...

Insect herbivores often have higher densities on host plants grown in monocultures than those in diverse environments. The underlying mechanisms are thought to be that polyphagous insects have difficulty in selecting food or oviposition sites when multiple host plants exist. However, this hypothesis needs to be extensively investigated. Our field experiments revealed that the population of the ...

Plants are attacked by a broad array of herbivores and pathogens. In response, plants deploy an arsenal of defensive traits. In Brassicaceae, the glucosinolate-myrosinase complex is a sophisticated two-component system to ward off opponents. However, this so-called "mustard oil bomb" is disarmed by a glucosinolate sulfatase of a crucifer specialist insect, diamondback moth, Plutella xylostella ...

the previous record of diadegma anurum (thomson) as a parasitoid of diamondback moth, plutella xylostella (l.) (lep.: plutellidae), from iran has just been a misidentification of diadegma semiclausum (hellen).

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...

J. Econ. Entomo!. 89(6): 1364-1371 (1996) ABSTRACT The concentration-mortality responses of 6-8 populations of Plutella xylostella (L.) from leaf-dip bioassays were compared with the mortality of larvae caused by residues of ' field applications of Badllus thuringiensis subsp. kurstaki Berliner (Javelin Wettable Granules 6.4% [AI]), and mortality of larvae in 3 diagnostic concentrations of Jave...

Thermal sensitivity is a crucial determinant of insect abundance and distribution. The way it is measured can have a critical influence on the conclusions made. Diamondback moth (DBM), Plutella xylostella (L.) (Lepidoptera: Plutellidae) is an important insect pest of cruciferous crops around the world and the thermal responses of polyphagous species are critical to understand the influences of ...
