| characterization of adelphocoris suturalis (hemiptera: miridae) transcriptome from different developmental stages. | adelphocoris suturalis is one of the most serious pest insects of bt cotton in china, however its molecular genetics, biochemistry and physiology are poorly understood. we used high throughput sequencing platform to perform de novo transcriptome assembly and gene expression analyses across different developmental stages (eggs, 2(nd) and 5(th) instar nymphs, female and male adults). we obtained 20 gb of clean data and revealed 88,614 unigenes, including 23,830 clusters and 64,784 singletons. thes ... | 2015 | 26047353 |
| the genome sequence of a novel rna virus in adelphocoris suturalis. | the complete genome of a novel virus found in adelphocoris suturalis was determined by rna-seq and named adelphocoris suturalis-associated virus 1 (asv1). asv1 has a single-stranded rna genome of 10,845 nucleotides in length and contains five putative open reading frames (orfs). orf1 encodes a polypeptide of 2592 amino acids (aa) and contains four conserved domains: a viral rna methyltransferase domain, an ftsj-like methyltransferase domain, a viral rna helicase domain and an rna-dependent rna p ... | 2017 | 28108803 |
| evidence of female-produced sex pheromone of adelphocoris suturalis (hemiptera: miridae): effect of age and time of day. | after the reduction in the use of broad-spectrum insecticides, adelphocoris suturalis (hemiptera: miridae) has become an important pest of transgenic cotton, gossypium hirsutum l., in china. a. suturalis is a highly mobile insect, moving rapidly in and out of crop fields, and traps baited with sex pheromones may be useful in monitoring and controlling its numbers. however, little is currently known regarding the chemical communication based on sex pheromones by this species. to use the synthesiz ... | 2011 | 21882682 |
| a transgenic strategy for controlling plant bugs (adelphocoris suturalis) through expression of double-stranded rna homologous to fatty acyl-coenzyme a reductase in cotton. | plant bugs (miridae species), which are sap-sucking insects, have emerged as major pests of cotton in china. most miridae species are not sensitive to commercial bacillus thuringiensis (bt) cotton, resulting in significant economic losses and an increased application of insecticide, which eventually may compromise the future of bt cotton. we demonstrate that fatty acyl-coa reductase (asfar) plays an essential role in the reproduction of the bug adelphocoris suturalis. down-regulation of asfar ex ... | 2017 | 28608990 |
| early-season host switching in adelphocoris spp. (hemiptera: miridae) of differing host breadth. | the mirid bugs adelphocoris suturalis (jakovlev), adelphocoris lineolatus (goeze) and adelphocoris fasciaticollis (reuter) (hemiptera: miridae) are common pests of several agricultural crops. these three species have vastly different geographical distributions, phenologies and abundances, all of which are linked to their reliance on local plants. previous work has shown notable differences in adelphocoris spp. host use for overwintering. in this study, we assessed the extent to which each of the ... | 2013 | 23527069 |
| transgenic bt cotton expressing cry1ac/cry2ab or cry1ac/epsps does not affect the plant bug adelphocoris suturalis or the pollinating beetle haptoncus luteolus. | the widespread cultivation of transgenic bt cotton makes assessing the potential effects of this recombinant crop on non-target organisms a priority. however, the effect of bt cotton on many insects is currently virtually unknown. the plant bug adelphocoris suturalis is now a major pest of cotton in southern china and the beetle haptoncus luteolus is one of the most ancient cotton pollinators. we conducted laboratory experiments to evaluate the toxicity of the bt cotton varieties zmsj, which exp ... | 2017 | 29247941 |
| comparative mitogenomic analysis of mirid bugs (hemiptera: miridae) and evaluation of potential dna barcoding markers. | the family miridae is one of the most species-rich families of insects. to better understand the diversity and evolution of mirids, we determined the mitogenome of lygus pratenszs and re-sequenced the mitogenomes of four mirids (i.e., apolygus lucorum, adelphocoris suturalis, ade. fasciaticollis and ade. lineolatus). we performed a comparative analysis for 15 mitogenomic sequences representing 11 species of five genera within miridae and evaluated the potential of these mitochondrial genes as mo ... | 2017 | 28791201 |
| knockdown of a metathoracic scent gland desaturase enhances the production of (e)-4-oxo-2-hexenal and suppresses female sexual attractiveness in the plant bug adelphocoris suturalis. | insect sex pheromones (sps) are central to mate-finding behaviour, and play an essential role in the survival and reproduction of organisms. understanding the roles, biosynthetic pathways and evolution of insect chemical communication systems has been an exciting challenge for biologists. compared with lepidoptera, little is known about the mechanisms underlying pheromone biosynthesis in hemiptera. in this study, we isolated and characterized two new desaturase-like genes, termed asutdes1 and as ... | 2017 | 28621451 |
| odorant-binding and chemosensory proteins identified in the antennal transcriptome of adelphocoris suturalis jakovlev. | adelphocoris suturalis jakovlev (hemiptera: miridae) is an insect pest that causes severe agricultural damage to cotton and many other important crops. in insects, olfaction is very important throughout their lifetime. there are two groups of small soluble proteins, named odorant binding proteins (obps) and chemosensory proteins (csps), which are suggested to participate in the initial biochemical recognition steps of insect olfactory signal transduction. in this study, a total of 16 obps (12 cl ... | 2017 | 27085212 |
| phylogeographic structure of cotton pest adelphocoris suturalis (hemiptera: miridae): strong subdivision in china inferred from mtdna and rdna its markers. | phylogeographic patterns of some extant plant and vertebrate species have been well studied; however, they are poorly understood in the majority of insects. the study documents analysis of mitochondrial (coi, cytb and nd5) and nuclear (5.8s rdna, its2 and 28s rdna) data from 419 individuals of adelphocoris suturalis, which is one of the main cotton pests found in the 31 locations in china and japan involved in the study. results show that the species is highly differentiated between populations ... | 2015 | 26388034 |
| morphology and chemical analysis of the metathoracic scent glands system in adelphocoris suturalis (hemiptera: miridae). | the morphological structure of the metathoracic scent glands (mtgs) in adelphocoris suturalis was observed by utilizing scanning electron microscope (sem). also, the secretions of mtgs in male and female were analyzed by using gas chromatography-mass spectrometry (gc-ms). the result showed that the mtgs comprised a reservoir and paired lateral glands, which are connected to a reservoir by duct. the mtgs belong to the diastomian type. a usually depressed channel extends from opening downward the ... | 2014 | 25527598 |
| de novo analysis of the adelphocoris suturalis jakovlev metathoracic scent glands transcriptome and expression patterns of pheromone biosynthesis-related genes. | adelphocoris suturalis jakovlev is a major cotton pest in southern china. metathoracic scent glands (mtgs) produced pheromones that play an important role in survival and population propagation of this species, and also show great potential for pest control. up to the present, there is little information that underlined the molecular basis of the pheromone biosynthesis of this bug. it is essential to clarify genes involved in the production of pheromone components, and also in the regulation of ... | 2014 | 25194898 |
| diapause induction in apolygus lucorum and adelphocoris suturalis (hemiptera: miridae) in northern china. | with widespread planting of bt cotton and an associated reduction in the use of broad-spectrum insecticides, the mirid bugs apolygus lucorum (meyer-dür) and adelphocoris suturalis jakovlev (hemiptera: miridae) become major pests of cotton in northern china in recent years. both species overwinter as diapausing eggs that may enhance ability to survive the cold winter. the effects of photoperiod and temperature on diapause induction in a. lucorum and a. suturalis were investigated under laboratory ... | 2012 | 23321109 |
| effects of transgenic bt cotton on the population density, oviposition behavior, development, and reproduction of a nontarget pest, adelphocoris suturalis (hemiptera: miridae). | transgenic cotton has shown great promise for the control of target pest insects; however, frequent outbreaks of nontarget pest mirids has been recorded in recent years in northern china. to test the hypothesis that transgenic cotton contributes to nontarget pest outbreaks, we studied the impact of transgenic bt cottons (both bt and bt + cpti) on the fitness of nontarget pest adelphocoris suturalis jakovlev. no significant differences were detected between population densities of a. suturalis in ... | 2010 | 22127190 |
