Laboratory tests with Diadegma insulare (Cresson), a parasitoid of the diamondback moth ( Plutella xylostella (L.)), were conducted to evaluate the viability of cocoons stored at 4 ° C for varying lengths of time and also the effects of parasitism by D. insulare on the feeding rate of diamondback moth larvae. The percentage of adults emerging from cocoons declined steadily with time spent in st...

The feeding activity of Plutella xylostella in brassica crops can lead to large losses; thus, pesticides that prevent during the larval stage or metamorphosis this insect be used for its control. In study, effects two types aqueous extracts Tradescantia pallida on different life P. cycle were tested; neither extracts, which obtained by infusion and maceration, had been tested against xylostella...

Plutella xylostella (Linnaeus, 1758), the diamondback moth is an important pest in Brassicae cultivars world. However, description regarding different biological stages and information about performance parameters of P. are to survey fields design effective management. In this study, wild population was adapted on white cabbage then cauliflower, broccoli leaves were tested under laboratory cond...

The diamondback moth Plutella xylostella (Linnaeus) (Lepidoptera: Plutellidae) is one of the most destructive insect pests of cruciferous plants worldwide. Biological, ecological and genetic studies have indicated that this moth is migratory in many regions around the world. Although outbreaks of this pest occur annually in China and cause heavy damage, little is known concerning its migration....

In the first instar, the larvae enter into the leaf parenchyma and feed between the upper and lower surfaces of leaves creating mines. In the second instar, the larvae leave the mines, and from the second to the third instar, they feed on the leaves, destroying the leaf tissue except for the upper epidermis, leaving transparent “windows” in the leaves. Fourth-instar larvae feed on both sides of...

Two strains of the diamondback moth, Plutella xylostella (L.), were selected using Cry1C protoxin and transgenic broccoli plants expressing a Cry1C toxin of Bacillus thuringiensis (Bt). Both strains were resistant to Cry1C but had different cross-resistance patterns. We used 12 Bt protoxins for cross-resistance tests, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Bb, Cry1C, Cry1D, Cry1E, Cry1F, Cry1J, ...
