Comprehensive analysis of the overexpressed cytochrome P450-based insecticide resistance mechanism in Spodoptera litura.

Journal of Hazardous Materials, 2023
Cytochrome P450s play critical roles in the metabolic resistance of insecticides in insects. Previous findings showed that enhanced P450 activity was an important mechanism mediating indoxacarb resistance, and multiple P450 genes were upregulated in ...

Inducible Gut-Specific Carboxylesterase SlCOE030 in Polyphagous Pests of Spodoptera litura Conferring Tolerance between Nicotine and Cyantraniliprole.

Journal of Agricultural and Food Chemistry, 2023
Insecticides tolerance in herbivorous arthropods is associated with preadaptation to host plant allelochemicals. However, how plant secondary metabolites activate detoxifying metabolic genes to develop tolerance remains unclear.

Functional analysis of UDP-glycosyltransferase genes conferring indoxacarb resistance in Spodoptera litura.

Pesticide Biochemistry and Physiology, 2023
UDP-glycosyltransferase (UGT) is the major detoxification enzymes of phase II involved in xenobiotics metabolism, which potentially mediates the formation of insect resistance.

CYP321A Subfamily P450s Contribute to the Detoxification of Phytochemicals and Pyrethroids in Spodoptera litura.

Journal of Agricultural and Food Chemistry, 2023
Although the induction of cytochrome P450 monooxygenases involved in insect detoxification has been well documented, the underlying regulatory mechanisms remain obscure. In Spodoptera litura, CYP321A subfamily members were effectively induced by exposure

Monitoring and characterization of field‐evolved resistance to diamide insecticides in Spodoptera litura collected from eastern China

Journal of applied entomology, 2023
Spodoptera litura is a notoriously destructive pest, which infests horticultural plants and economically important crops worldwide. Several generations of diamide insecticides have been used to combat S.

Biodegradable Electrospun Fibers as Sustained-Release Carriers of Insect Pheromones for Field Trapping of Spodoptera litura (Lepidoptera: Noctuidae).

Pest Management Science, 2023
BACKGROUND Insect pheromones are highly effective and environmentally friendly, and are widely used in the monitoring and trapping of pests. However, many researchers have found that various factors such as ultraviolet light and temperature in the field ...

Nuclear receptors potentially regulate phytochemical detoxification in Spodoptera litura.

Pesticide Biochemistry and Physiology, 2023
Phytochemicals are a class of potential pesticides for pest control. Our previous studies have demonstrated that the development of Spodoptera litura is suppressed by two phytochemicals, flavone and xanthotoxin. Generally, phytochemical is metabolized by

Role of the epsilon glutathione S-transferases in xanthotoxin tolerance in Spodoptera litura.

Pesticide Biochemistry and Physiology, 2023
Spodoptera litura, a polyphagous lepidopteran pest, demonstrates a remarkable capacity to adapt to varying host plants by efficiently detoxifying phytochemicals. However, the underlying mechanism for this adaptation is not well understood. Herein, twenty

Inducible Cytochrome P450s in the Fat Body and Malpighian Tubules of the Polyphagous Pests of Spodoptera litura Confer Xenobiotic Tolerance.

Journal of Agricultural and Food Chemistry, 2023
Cytochrome P450 plays vital roles in detoxifying xenobiotics. In this study, SlCYP340A and SlCYP340L expression in the Spodoptera litura fat body and SlCYP332A1, SlCYP6AB12, SlCYP6AB58, SlCYP6AB59, and SlCYP6AN4 expression in the Malpighian tubules were ...

In vitro biosynthesis of volicitin in Spodoptera litura

Insect Biochemistry and Molecular Biology, 2005
Volicitin [N-(17-hydroxylinolenoyl)-L-glutamine] and N-linolenoyl-L-glutamine, originally identified in the regurgitant of Spodoptera exigua, induce damaged corn leaves to release volatile compounds which enable parasitic wasps to locate host caterpillars.
