RNA INTERFERENCE OF TWO ACETYLCHOLINESTERASE GENES IN Plutella xylostella REVEALS THEIR DIFFERENT FUNCTIONS

open access: closedArchives of Insect Biochemistry and Physiology, 2012
Acetylcholinesterase (AChE, EC 3.1.1.7) is an important enzyme with a typical function of degrading the neurotransmitter acetylcholine. Although two ace genes were reported in Plutella xylostella, their function differences remain largely unknown. The chemically synthesized siRNAs (si‐Pxace1 and si‐Pxace2) were injected into the second instar larvae to

Novel genetic factors involved in resistance to B acillus thuringiensis in P lutella xylostella

open access: closedInsect Molecular Biology, 2015
Abstract The widespread and sustainable exploitation of the entomopathogen Bacillus thuringiensis ( Bt ) in pest control is threatened by the evolution of resistance. Although resistance is often associated with loss of binding of the

A point mutation in the glutamate‐gated chloride channel of P lutella xylostella is associated with resistance to abamectin

open access: closedInsect Molecular Biology, 2015
Abstract The diamondback moth, Plutella xylostella , is a global pest of cruciferous vegetables. Abamectin resistance in a field population of P. xylostella was introgressed into the susceptible Roth strain. The resulting introgression

Diadegma insulare development is altered by Plutella xylostella reared on water‐stressed host plants

open access: closedJournal of Applied Entomology, 2015
AbstractNatural enemies of herbivores function in a multitrophic context, and their performance is directly or indirectly influenced by herbivores and their host plants. Very little is known about tritrophic interactions between host plants, pests and their parasitoids, particularly when the host plants are under any stress.

Geographical variation of Plutella xylostella (Lepidoptera: Plutellidae) populations revealed by mitochondrial COI gene in China

open access: closedJournal of Applied Entomology, 2014
AbstractThe diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is one of the most serious pests for cruciferous vegetable growers worldwide. To determine the relations of local and regional populations, we performed a mitochondrial COI gene analysis of eight P. xylostella populations from different locations in or around the Qinling

Temperature‐sensitive fitness cost of insecticide resistance in Chinese populations of the diamondback moth Plutella xylostella

open access: closedMolecular Ecology, 2015
AbstractAlleles conferring a higher adaptive value in one environment may have a detrimental impact on fitness in another environment. Alleles conferring resistance to pesticides and drugs provide textbook examples of this trade‐off as, in addition to conferring resistance to these molecules, they frequently decrease fitness in pesticide/drug‐free ...

A single type of cadherin is involved in B acillus thuringiensis toxicity in P lutella xylostella

open access: closedInsect Molecular Biology, 2015
Abstract Cadherins have been described as one the main functional receptors for the toxins of the entomopathogenic bacterium, Bacillus thuringiensis ( Bt ).
