Journal ArticleDOI
RNA interference-mediated knockdown of a cytochrome P450, CYP6BG1, from the diamondback moth, Plutella xylostella, reduces larval resistance to permethrin
TL;DR: Results indicate that the overexpressed CYP6BG1 participate in enhanced metabolism of permethrin, thereby, resistance and RNA interference-mediated gene silencing by dsRNA droplet feeding is adopted.
Journal ArticleDOI
Identification and characterization of ace1-type acetylcholinesterase likely associated with organophosphate resistance in Plutella xylostella
TL;DR: In this paper, a second copy of the ace2-type DBM AChE gene was cloned and characterized, and the deduced amino acid sequence showed the highest homology to ace1, and was determined in fact as the predominant ACHE in DBM compared to the ace 2-type with 13 to 250fold higher transcription levels depending on different tissues.
Journal ArticleDOI
Selections for fenpyroximate resistance and susceptibility, and inheritance, cross-resistance and stability of fenpyroximate resistance in Tetranychus urticae Koch (Acari: Tetranychidae)
Mário Eidi Sato,Tadashi Miyata,Marcos Zatti da Silva,Adalton Raga,Miguel Francisco de Souza Filho +4 more
TL;DR: F Frequencies of fenpyroximate resistance decline significantly in the absence of selection pressure, under laboratory conditions, however, the rate of decline is not high.
Journal ArticleDOI
Synergism of enzyme inhibitors and mechanisms of insecticide resistance in Bemisia tabaci (Gennadius) (Hom., Aleyrodidae)
C. Y. Kang,G. Wu,Tadashi Miyata +2 more
TL;DR: The results suggest that the resistance to organophosphates in B. tabaci was associated partly with AChE insensitivity, which might provide a plausible explanation for the improvement in insecticide toxicity by the three enzyme inhibitors.
Journal ArticleDOI
Identification of permethrin-inducible cytochrome P450s from the diamondback moth, Plutella xylostella (L.) and the possibility of involvement in permethrin resistance
TL;DR: Insect cytochrome P450 monooxygenases (P450s) are important enzymes involved in catalysis of many reactions leading to insecticide resistance, and inducibility of the isolated P450s at the transcript level, specifically the overexpressed ones were analyzed and correlated with permethrin toxicity.
