Transgenic cotton that has been engineered to produce insecticidal toxins from Bacillus thuringiensis (Bt) and so resist the pest bollworm (Helicoverpa armigera) widely planted in Asia. Analysis of population dynamics H. armigera 1992 2007 China indicated a marked decrease regional outbreaks this multiple crops was associated with planting Bt cotton. The study area included six provinces northern an annual total 3 million hectares 22 other (corn, peanuts, soybeans, vegetables) grown by more...
Collateral Damage Cotton crops that have been bioengineered to express the insecticidal toxin derived from Bacillus thuringiensis (Bt) carry their own insect control, particularly against cotton bollworm, and are less dependent on externally applied pesticides. Lu et al. (p. 1151 , published online 13 April) now show reduction in general pesticide use cotton-growing regions of northern China has shifted balance regional pest populations. Bt-expressing serves as a source herbivorous insects...
Abstract The rapid wide‐scale spread of fall armyworm ( Spodoptera frugiperda ) has caused serious crop losses globally. However, differences in the genetic background subpopulations and mechanisms adaptation behind invasion are still not well understood. Here we report assembly a 390.38‐Mb chromosome‐level genome derived from south‐central Africa using Pacific Bioscience (PacBio) Hi‐C sequencing technologies, with scaffold N50 12.9 Mb containing 22,260 annotated protein‐coding genes....
Since 2016, the fall armyworm (FAW) Spodoptera frugiperda has spread over extensive areas of tropics and subtropics, imperiling food security, economic progress livelihoods millions cereal farmers. Although FAW received long-standing scientific attention in its home range Americas, chemical inputs feature prominently mitigation biological control uptake is globally lagging. Here, building upon a quantitative review global literature, we methodically dissect science. Of known entomopathogens...
Development of insect resistance is one the main concerns with use transgenic crops expressing Cry toxins from bacterium Bacillus thuringiensis. Identification biomarkers would assist in development sensitive DNA-based methods to monitor evolution Bt natural populations. We report on proteomic and genomic detection reduced levels midgut membrane-bound alkaline phosphatase (mALP) as a common feature strains Cry-resistant Heliothis virescens, Helicoverpa armigera Spodoptera frugiperda when...
Toxins from the bacterium Bacillus thuringiensis (Bt) are used widely for insect control in sprays and transgenic plants, but their efficacy is reduced when pests evolve resistance. Previous work showed that mutations a gene encoding transporter protein ABCC2 linked with resistance to Bt toxins Cry1Ab, Cry1Ac or both four species of Lepidoptera. Here we compared Helicoverpa armigera (HaABCC2) between susceptible strains laboratory-selected strain >1,000-fold relative its parent strain. We...
The tobacco whitefly Bemisia tabaci is one of the most devastating pests worldwide.Current management B. relies upon frequent applications insecticides.In addition to direct mortality by typical acute toxicity (lethal effect), insecticides may also impair various key biological traits exposed insects through physiological and behavioral sublethal effects.Identifying characterizing such effects could be crucial for understanding global on pest therefore optimizing its in crops.We assessed...
Insect chemosensory proteins (CSPs) have been proposed to capture and transport hydrophobic chemicals from air olfactory receptors in the lymph of antennal chemosensilla. They may represent a new class soluble carrier protein involved insect chemoreception. However, their specific functional roles chemoreception not fully elucidated. In this study, we report for first time three novel CSP genes (AlinCSP1-3) alfalfa plant bug Adelphocoris lineolatus (Goeze) by screening cDNA library. The...
Fall armyworm has invaded China and colonized its populations in tropical sub-tropical regions of South since December 2018. Chemical spray been widely used to control the pest, which shall lead resistance evolution. In this research, we collected five pest from Yunnan, Hainan, Tibet, Fujian China, tested their susceptibilities pyrethroid, organophosphorus, oxadiazine, diamide, antibiotics other types insecticides (14 totally) laboratory. Based on susceptible baseline published previous...
Mutualistic associations between symbiotic bacteria and their hosts are common within insect systems. However, viruses often considered as pathogens even though some have been reported to be beneficial hosts. Herein, we report a novel densovirus, Helicoverpa armigera densovirus-1 (HaDNV-1) that appears its host. HaDNV-1 was found widespread in wild populations of H. adults (>67% prevalence 2008 2012). In larval populations, there clear negative interaction nucleopolyhedrovirus (HaNPV),...
The fall armyworm (FAW), native to the Americas, has rapidly invaded whole of Southern China since January 2019. In addition, it can survive and breed in key maize- rice- growing area Yangtze River Valley. Furthermore, this pest is also likely continue infiltrating other cropping regions China, where food security facing a severe threat. To understand potential infestation newly-invaded FAW from Valley, we simulated predicted possible flight pathways range populations using numerical...
Significance Crops genetically engineered to produce insecticidal proteins from the bacterium Bacillus thuringiensis (Bt) kill some major pests and reduce use of insecticide sprays. However, evolution pest resistance Bt decreases these benefits. We report a strategy for combating by crossing transgenic plants with conventional non-Bt then sowing second-generation seeds. This yields random mixture within fields three-quarters that protein one-quarter does not. An 11-y field study in China...
In December 11, 2018, the fall armyworm (FAW), Spodoptera frugiperda invaded China and has since impacted local maize, sorghum other crops. Here, we draw on laboratory experiments to show how different host crops (i.e., sorghum, wheat rice) artificial diet affect larval growth adult reproduction of one FAW strain. Larval affected development duration, pupation rate, survival emergence rate pupae, S. fecundity. attained slowest (19.4 days) fastest (14.1 diet, with larvae attaining 99.6%...
The fall armyworm (FAW), Spodoptera frugiperda, is a newly invasive, widespread agricultural pest in China. Understanding the suitability of main field crops Chinese system as host for this polyphagous herbivore especially important making control strategy. Here, after FAWs were fed three oil-bearing (oilseed rape, soybean and sunflower) planted China resultant population parameters compared using age-stage, two-sex life table method, survival larvae on was significantly lower than that...
Insects provide critical ecosystem services such as biological pest control, in which natural enemies (NE) regulate the populations of crop-feeding herbivores (H). While H-NE dynamics are routinely studied at small spatiotemporal scales, multiyear assessments over entire agrolandscapes rare. Here, we draw on 18-year radar and searchlight trapping datasets (2003–2020) from eastern Asia to (i) assess temporal population trends 98 airborne insect species (ii) characterize associated interplay....

The vegetative insecticidal protein Vip3Aa from Bacillus thuringiensis (Bt) has been produced by transgenic crops to counter pest resistance the widely used crystalline (Cry) proteins Bt. To proactively manage resistance, there is an urgent need better understand genetic basis of Vip3Aa, which largely unknown. We discovered that retrotransposon-mediated alternative splicing a midgut-specific chitin synthase gene was associated with 5,560-fold in laboratory-selected strain fall armyworm,...
