Background Multiple mutations in the voltage-gated sodium channel have been associated with knockdown resistance (kdr) to DDT and pyrethroid insecticides a major human disease vector Aedes aegypti. One mutation, V1016G, confers pyrethroids, but different substitution same position V1016I alone had no effect. In pyrethroid-resistant Ae. aegypti populations, is often linked another F1534C, which only Type I pyrethroids including permethrin (PMT), not II deltamethrin (DMT). Mosquitoes carrying...
Neonicotinoids have been widely used to control pests with remarkable effectiveness. Excessive insecticides led serious insect resistance. Mutations of the nicotinic acetylcholine receptor (nAChR) are one reasons for neonicotinoid resistance conferred in various agricultural pests. Two mutations, V65I and V104I, were found nAChR β1 subunit two neonicotinoid-resistant aphid populations. However, specific functions mutations remain unclear. In this study, we cloned identified four subunits...
The intensification of environmental pollution and the destruction ozone layer has increased amount ultraviolet (UV) radiation reaching surface daily, which resulted in great selective pressure for plants insects biosphere. UV light stress can seriously affect growth development insects, such as retardation, fecundity weakening, life span shortening. Protective detoxification enzymes, are two important adaptive enzyme systems play a dominant role regulating insect response to stress. On...
Insecticides are widely used to control pests in agriculture and insect vectors that transmit human diseases. However, these chemicals can have a negative effect on nontarget, beneficial organisms including bees. Discovery deployment of selective insecticides is major mission modern toxicology pest management. Pyrethroids exert their toxic action by acting voltage-gated sodium channels. Honeybees bumblebees highly sensitive most pyrethroids, but resistant particular pyrethroid,...
Surface-enhanced Raman spectroscopy (SERS) is considered to be a powerful analysis tool for the detection of molecules due its ultra-high sensitivity and non-destructive nature. Here, we introduce new type hybrid SERS substrate, where gold nanorods are assembled on structured support containing top dielectric grating, spacer mirror. Compared with conventional metal nanoparticle assemblies flat support, our substrate shows an approximately 30-fold enhancement in signal. Numerical simulations...
Background Volatile pyrethroid insecticides, such as transfluthrin, have received increasing attention for their potent repellent activities in recent years controlling human disease vectors. It has been long understood that pyrethroids kill insects by promoting activation and inhibiting inactivation of voltage-gated sodium channels. However, the mechanism repellency remains poorly controversial. Methodology/Principal findings Here, we show transfluthrin repels Aedes aegypti a hand-in-cage...
Introduction: Gene expression analysis by reverse transcription quantitative polymerase chain reaction (qRT-PCR) has been widely used in research including insects. The selection of appropriate reference genes is the key to obtaining accurate and reliable results from qRT-PCR. However, studies on stability Megalurothrips usitatus remain lacking. Methods: In this study, qRT-PCR was analyze candidate M. usitatus. levels six gene were analyzed. GeNorm, NormFinder, BestKeeper, ΔCt treated with...
Among various host plants, Spodoptera frugiperda primarily infests corn.Once the long-term regional colonization,if larvae feed on sweet waxy corn and fresh for a long time, what is rhythm of adults? Can using serve as functional plant? There are no reports this at present. To aid in development effective prevention control measures, Zhengdan 958 Zhenghuangnuo were utilized representatives normal laboratory. S. was fed these two types leaves over nine generations, establishing lineage...
As a major invasive pest in China, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) has caused great damage to crops. Hymenopteran parasitoids, especially the braconid wasps, play crucial roles depressing populations. However, there was little information about ideal storage of parasitoids achieve their mass-rearing. Here, we identified dominant parasitoid S. frugiperda, Microplitis manilae (Ashmead) (Hymenoptera: Braconidae), Hainan province China with field parasitism rate...
The effectiveness of pyrethroid insecticides is seriously threatened by knockdown resistance (kdr), which induced in insects inherited single-nucleotide polymorphisms the voltage-gated sodium channel (VGSC) gene. VGSC's L1014F substitution results classic kdr mutation, found many pest species. Other substitutions L1014 locus, such as L1014S, L1014C, L1014W, and L1014H, were also reported. In 2022, a new amino acid substitute L1014S Blattella germanica was first discovered China. We modified...
The bacterial artificial chromosome (BAC) system is widely used in isolation of large genomic fragments interest. Construction a routine BAC library requires several months for picking clones and arraying BACs into superpools order to employ 4D-PCR screen positive BACs, which might be time-consuming laborious. major histocompatibility complex (MHC) cluster genes involved the vertebrate immune system, classical avian MHC-B locus minimal essential one, occupying 100-kb region. In this study,...
Nanotransfer printing (nTP) technology can generate highly functional three-dimensional (3D) nanostructures in a low-cost and high-throughput fashion. Nevertheless, the fabrication yield quality of transferred are often limited by merging surface patterns replica stamps during transfer printing. Here, an nTP was developed to fabricate large-area crack-free 3D multilayer nanostructures. Instead directly depositing materials on patterned flexible stamp conventional nTPs, we straightforwardly...

ABSTRACT The damage caused by Megalurothrips usitatus , a common pest, has significantly affected the Chinese vegetable industry. inappropriate application of chemical pesticides M. to become highly resistant conventional insecticides. Glutathione S‐transferase (GST), known for its multifunctional properties, contributes detoxification and antioxidation. It enhances insects' adaptability facilitating elimination lipid peroxidation products resulting from pyrethroid This research employed...
Transgenic cotton has shown great promise for the control of target pest insects; however, frequent outbreaks nontarget mirids been recorded in recent years northern China. To test hypothesis that transgenic contributes to outbreaks, we studied impact Bt cottons (both and + CpTI) on fitness Adelphocoris suturalis Jakovlev. No significant differences were detected between population densities A. unsprayed nontransgenic 2007, 2008, 2009. difference preferred oviposition site or egg production...
Abstract Spodoptera frugiperda invaded China in the end of 2018 and has caused severe damage to maize other crops. Several S. naturally parasitized by nematodes were observed Hainan Province, China. The morphological characteristics based on results scanning electron microscopy indicated that nematode belongs family Mermithidae. Additionally, coding sequences for 18 S 28 rDNA amplified from genome, phylogenetic analysis revealed Ovomermis sinensis , a known entomoparasitic nematode. Our...
