| population dynamics of sesamia inferens on transgenic rice expressing cry1ac and cpti in southern china. | genetically modified insect-resistant rice lines containing the cry1ac gene from bacillus thuringiensis (bt) or the cpti (cowpea trypsin inhibitor) gene developed for the management of lepidopterous pests are highly resistant to the major target pests, chilo suppressalis (walker), cnaphalocrocis medinalis (guenée), and scirpophaga incertulas (walker), in the main rice-growing areas of china. however, the effects of these transgenic lines on sesamia inferens (walker), an important lepidopterous r ... | 2008 | 19036217 |
| screen of bacillus thuringiensis toxins for transgenic rice to control sesamia inferens and chilo suppressalis. | transgenic rice to control stem borer damage is under development in china. to assess the potential of bacillus thuringiensis (bt) transgenes in stem borer control, the toxicity of five bt protoxins (cry1aa, cry1ab, cry1ac, cry1ba and cry1ca) against two rice stem borers, sesamia inferens (pink stem borer) and chilo suppressalis (striped stem borer), was evaluated in the laboratory by feeding neonate larvae on artificial diets containing bt protoxins. the results indicated that cry1ca exhibited ... | 2010 | 20452358 |
| baseline sensitivity of lepidopteran corn pests in india to cry1ab insecticidal protein of bacillus thuringiensis. | genetically engineered corn (bt corn) expressing bacillus thuringiensis berliner insecticidal protein cry1ab is a biotechnological option being considered for management of lepidopteran corn pests in india. as a resistance management practice it was essential to determine the sensitivity of multiple populations of the stalk borer chilo partellus (swinhoe), pink borer sesamia inferens (walker) and the cob borer helicoverpa armigera (hübner) to cry1ab protein through bioassays. the insect populati ... | 2010 | 20602522 |
| transgenic rice plants expressing a fused protein of cry1ab/vip3h has resistance to rice stem borers under laboratory and field conditions. | six transgenic rice, oryza sativa l., lines (g6h1, g6h2, g6h3, g6h4, g6h5, and g6h6) expressing a fused cry1ab/vip3h protein, were evaluated for resistance against the asiatic rice borer, chilo suppressalis (walker) (lepidoptera: crambidae), and the stem borer sesamia inferens (walker) (lepidoptera: noctuidae) in the laboratory and field. the bioassay results indicated that the mortality of asiatic rice borer and s. inferens neonate larvae on six transgenic lines from seedling to filling stage w ... | 2010 | 20857760 |
| evaluating the non-rice host plant species of sesamia inferens (lepidoptera: noctuidae) as natural refuges: resistance management of bt rice. | although rice (oryza sativa l.) lines that express bacillus thuringiensis (bt) toxins have shown great potential for managing the major lepidoptera pests of rice in southern china, including sesamia inferens, their long-term use is dependent on managing resistance development to bt toxins in pest populations. the maintenance of "natural" refuges, non-bt expressing plants that are hosts for a target pest, has been proposed as a means to minimize the evolution of resistance to bt toxins in transge ... | 2011 | 22251655 |
| the complete mitochondrial genome of the rice moth, corcyra cephalonica. | the complete mitochondrial genome (mitogenome) of the rice moth, corcyra cephalonica stainton (lepidoptera: pyralidae) was determined as a circular molecular of 15,273 bp in size. the mitogenome composition (37 genes) and gene order are the same as the other lepidopterans. nucleotide composition of the c. cephalonica mitogenome is highly a+t biased (80.43%) like other insects. twelve protein-coding genes start with a typical atn codon, with the exception of coxl gene, which uses cga as the initi ... | 2012 | 23413968 |
| differential expression patterns in chemosensory and non-chemosensory tissues of putative chemosensory genes identified by transcriptome analysis of insect pest the purple stem borer sesamia inferens (walker). | a large number of insect chemosensory genes from different gene subfamilies have been identified and annotated, but their functional diversity and complexity are largely unknown. a systemic examination of expression patterns in chemosensory organs could provide important information. | 2013 | 23894529 |
| antenna-predominant and male-biased csp19 of sesamia inferens is able to bind the female sex pheromones and host plant volatiles. | insect chemosensory proteins (csps) are proposed to capture and transport hydrophobic chemicals across the sensillum lymph to olfactory receptors (ors), but this has not been clarified in moths. in this study, we built on our previously reported segment sequence work and cloned the full length csp19 gene (sinfcsp19) from the antennae of sesamia inferens by using rapid amplification of cdna ends. quantitative real time-pcr (qpcr) assays indicated that the gene was expressed in a unique profile, i ... | 2014 | 24361960 |
| binding site concentration explains the differential susceptibility of chilo suppressalis and sesamia inferens to cry1a-producing rice. | chilo suppressalis and sesamia inferens are two important lepidopteran rice pests that occur concurrently during outbreaks in paddy fields in the main rice-growing areas of china. previous and current field tests demonstrate that the transgenic rice line huahui 1 (hh1) producing a cry1ab-cry1ac hybrid toxin from the bacterium bacillus thuringiensis reduces egg and larval densities of c. suppressalis but not of s. inferens. this differential susceptibility to hh1 rice correlates with the reduced ... | 2014 | 24928872 |
| antennal transcriptome analysis and comparison of olfactory genes in two sympatric defoliators, dendrolimus houi and dendrolimus kikuchii (lepidoptera: lasiocampidae). | the yunnan pine and simao pine caterpillar moths, dendrolimus houi lajonquière and dendrolimus kikuchii matsumura (lepidoptera: lasiocampidae), are two closely related and sympatric pests of coniferous forests in southwestern china, and olfactory communication systems of these two insects have received considerable attention because of their economic importance. however, there is little information on the molecular aspect of odor detection about these insects. furthermore, although lepidopteran ... | 2014 | 24998398 |
