Abstract BACKGROUND: Helicoverpa armigera (Hübner) is one of the most important pests in many countries. Spinosad used widely for control pests, but there sparse information available regarding its sublethal effects on H. . Here, authors attempt to investigate spinosad order reveal negative, non‐lethal impact insecticides this pest. RESULTS: The toxicity against was determined under laboratory conditions by oral exposure late second‐instar larvae compound. 48 h LC 50 and 72 values pest were...
A simple and effective method was established for separation characterization of flavonoid constituents in Radix Astragali (RA) by combination ultra-high-pressure liquid chromatography with LTQ-Orbitrap tandem mass spectrometry (u-HPLC-LTQ-Orbitrap-MSn). For three major structural types flavonoids, the proposed fragmentation pathways diagnostic fragment ions isoflavones, pterocarpans isoflavans were investigated to trace isoflavonoid derivatives crude plant extracts. Based on systematic...
The cotton bollworm, Helicoverpa armigera (Hübner) is one of the most serious insect pest species to evolve resistance against many insecticides from different chemical classes. This has evolved pyrethroid across its native range and becoming a truly global after establishing in South America having been recently recorded North America. A chimeric cytochrome P450 gene, CYP337B3, identified as mechanism for fenvalerate cypermethrin. Here we show that this common around world with at least...
Aedes albopictus (Skuse) is an important vector of chikungunya, dengue, yellow fever and Zika viruses. In the absence anti-viral medication with limited availability a commercial vaccine for public health use, control remains effective means reducing Aedes-borne disease morbidity. Knowledge about genetic mutations associated insecticide resistance (IR) prerequisite developing rapid diagnosis, distribution frequency IR conferring information making smart decisions.Partial DNA sequences domain...
BACKGROUND: Helicoverpa armigera (Hübner) causes severe losses in many crops including cotton. Cytochrome P450s play crucial roles the metabolism of important compounds various organisms. The authors attempt to identify new cytochrome P450 genes and investigate their expression profile xenobiotic response order understand nature this pest. RESULTS: A novel cDNA (CYP9A17), encoding a protein 531 amino acid residues, was isolated from H. armigera. CYP9A17 is typical microsomal P450, showing...
To isolate and characterize a methyl parathion (MP)-mineralizing bacterium, to elucidate the degradative pathway of MP localize responsible degrading genes.A bacterial strain, designated B2, capable mineralizing was isolated from MP-polluted soil. Analysis 16S rRNA gene sequence phenotypic analysis suggested that strain B2 had close relationship with Ochrobactrum anthropi. could totally degrade four metabolites [p-nitrophenol (PNP), 4-nitrocatechol (4-NC), 1,2,4-benzenetriol (BT)...
Insecticide resistance is a model phenotype that can be used to investigate evolutionary processes underlying the spread of alleles across global landscape, while offering valuable insights into solving problems resistant pests present human health and agriculture. Pyrethroids are one most widely classes insecticides world-wide they exert their toxic effects through interactions with voltage-sensitive sodium channel (Vssc). Specific mutations in Vssc (kdr, kdr-his super-kdr) known cause...
Increased insecticide detoxification mediated by cytochrome P450s is a common mechanism of resistance. Although Cyp6a2 has been observed to be overexpressed in many 4,4'-dichlorodiphenyltrichloroethane (DDT)-resistant strains Drosophila melanogaster, how regulated and whether its overproduction confers DDT resistance remain elusive.Molecular analysis identified five alleles (Cyp6a2(Canton) (-S-1) , Cyp6a2(Canton) (-S-2) Cyp6a2(91-C) Cyp6a2(91-R) Cyp6a2(Wisconsin) (-) (WD) ) from four D....
We report a transposase gene (tnpA) upstream of the opdA phosphotriesterase Agrobacterium radiobacter P230, as well inverted repeats indicative insertion sequences, flanking two genes. Both tnpA and resemble Tn610 transposon from Mycobacterium fortuitum. Two additional putative open reading frames separate with inferred translation products similarity to proteins encoded on Geobacillus stearothermophilus IS5376 transposon. To test proposition that these genes were contained transposon, an...
Background The German cockroach, Blattella germanica, is an important insect pest that transmits various pathogens mechanically and causes severe allergic diseases. This has long served as a model system for studies of biology, physiology ecology. However, the lack genome or transcriptome information heavily hinder our further understanding about cockroach in every aspect at molecular level on genome-wide scale. To explore identify unique sequences interest, we subjected B. germanica to...
