reproductive parameters and ovipositional preference of plutella xylostella were assessed on some mutant genotypes of canola (rgs 8-1, rgs 10-2, rgs 8-13, zar 9-9 and talaye 8-3) and their cultivars (rgs, zar, talaye) under greenhouse condition (21 ± 6 °c, 65 ± 10 rh and a photoperiod of 16l: 8d h). comparison of the reproductive parameters on rgs and its mutant genotypes revealed that mutant g...

Many parts of the Calotropis gigantea plant are known to contain bioactive compounds, but leaves most. This study aimed determine toxicity and antifeedant activity C. against Plutella xylostella. The was carried out from November 2019 July 2020. Toxicity tested using leaf dipping spraying methods. Antifeedant a no-choice test choice test. Identification compound composition extract at Integrate...

The larval midgut of diamondback moth, Plutella xylostella, is a dynamic tissue that interfaces with a diverse array of physiological and toxicological processes, including nutrient digestion and allocation, xenobiotic detoxification, innate and adaptive immune response, and pathogen defense. Despite its enormous agricultural importance, the genomic resources for P. xylostella are surprisingly ...

Cytochrome P450 monooxygenases are present in almost all organisms and can play vital roles in hormone regulation, metabolism of xenobiotics and in biosynthesis or inactivation of endogenous compounds. In the present study, a genome-wide approach was used to identify and analyze the P450 gene family of diamondback moth, Plutella xylostella, a destructive worldwide pest of cruciferous crops. We ...

Yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata, was evaluated as a trap crop for diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in cabbage, Brassica oleracea L. variety capitata, in 2003 and 2004. In 2003, the numbers of P. xylostella larvae found in field plots of cabbage alone were 5.2-11.3 times higher than those on cabbage plants in plots that included cab...

Glucosinolates are plant secondary metabolites used in plant defense. For insects specialized on Brassicaceae, such as the diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), glucosinolates act as "fingerprints" that are essential in host plant recognition. Some plants in the genus Barbarea (Brassicaceae) contain, besides glucosinolates, saponins that act as feeding deterrents ...

The levels of resistance to the insecticides cartap, deltamethrin and metamidophos were evaluated for three populations of the Diamondback Moth Plutella xylostella (L.) from the Federal District, Brazil in laboratory bioassays. The larvae of DBM showed levels of resistance to deltamethrin between 4 and 47 fold relative to a susceptible laboratory strain. The level of resistance to metamidophos ...

Although effects of thermal stability on eggs have often been considered in vertebrates, there is little data thermal stability in insect eggs even though these eggs are often exposed in nature to widely fluctuating ambient conditions. The modularity of development in invertebrates might lead to compensation across life cycle stages but this remains to be tested particularly within the context ...

The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), highly prefers to oviposit on yellow rocket, Barbarea vulgaris (R. Br.) (Cruciferae) var. arcuata , despite larvae not being able to survive on it, suggesting it may have potential as a trap crop. In a no-choice greenhouse experiment, P. xylostella laid 28% more eggs on B. vulgaris than on cabbage. Within the B. vulgaris...

The diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), is an important insect pest of cruciferous crops. Understanding its preference patterns can lead to more efficient management methods, such as trap Several strains P. were used test whether there differences in oviposition a four-choice setting, on abaxial versus adaxial leaf surfaces 28 different plant species, and substr...
