first steps to improve cotton crop management in thailand.	thai cotton growers yearly face serious pest problems consisting of heavy infestation associated with resistance to pesticides leading to expensive and harmful pest control practices. thanks to a multi discipline research work carried out from 1991 to 1996, a decision-oriented model for cotton crop management was developed and compared to farmers' practices during the 1988 cotton growing season 1998 in klang hat district, thailand. this model, based on plant monitoring, involved a new cotton cul ...	2001	12425063
development of controlled release formulations of carbofuran and imidacloprid and their bioefficacy evaluation against aphid, aphis gossypii and leafhopper, amrasca biguttula biguttula ishida on potato crop.	controlled release (cr) formulations of carbofuran and imidacloprid were prepared employing polyvinyl chloride and carboxymethyl cellulose (cmc) and their bioefficacy was evaluated against the aphid, aphis gossypii and leafhopper, amrasca biguttula biguttula ishida on potato crop. the cr formulations of carbofuran and imidacloprid provided better or equal control of the pests than commercial formulations. cmc-based formulation provided a superior control of both the pests. the imida-cmc, which s ...	2011	21806462
comparative studies on the effects of bt-transgenic and nontransgenic cotton on arthropod diversity, seedcotton yield and bollworms control.	the effectiveness of commercial bt-cotton in pest management, influence on arthropod diversity, natural enemies, and toxin flow in the insect fauna under field conditions were studied keeping in view the need to assess bioefficacy and biosafety of bt-transgenic cotton. there were no significant differences in oviposition by helicoverpa armigera on bt-transgenic and non-transgenic cottons (9.2 versus 9.6 eggs plants(-100)), while the numbers of h. armigera larvae were significantly more on non-tr ...	2013	24006809
impact of neonicotinoid seed treatment of cotton on the cotton leafhopper, amrasca devastans (hemiptera: cicadellidae), and its natural enemies.	neonicotinoid seed treatments suppress populations of pest insects efficiently and can enhance crop growth, but they may have negative effects on beneficial arthropods. we evaluated the effects of either imidacloprid or thiamethoxam on the abundances of a sucking pest, the cotton leafhopper (amrasca devastans), and its arthropod predators under field conditions. we also evaluated the impact of seed treatment on transgenic cotton plant growth, with pests and natural enemies present or absent.	2016	26436945
the toxicity of flonicamid to cotton leafhopper, amrasca biguttula (ishida), is by disruption of ingestion: an electropenetrography study.	the cotton leafhopper, amrasca biguttula, is one of the most destructive pests of cotton in asia. this species is thought to cause damage by injecting enzymatic saliva into various, presently unknown, cotton tissues and ingesting the resulting macerate. flonicamid is a novel systemic insecticide used to control the cotton leafhopper; however, its mode of action is unknown.	2017	27990759
patterns of genetic differentiation among populations of amrasca biguttula biguttula (shiraki) (cicadellidae: hemiptera).	cotton leafhopper, amrasca biguttula biguttula (shiraki), a serious sucking insect pest of cotton and vegetables is present throughout south and southeast asia. genetic differentiation within a. biguttula biguttula populations collected from 16 cotton growing areas of punjab, pakistan, was examined by sequencing the barcode region of the mitochondrial cytochrome oxidase subunit 1 (coi) gene. the dendrogram obtained by neighbour joining analysis of coi sequences confirmed the presence of single s ...	2017	28980839
mitochondria coi-based genetic diversity of the cotton leafhopper amrasca biguttula biguttula (ishida) populations from india.	amrasca biguttula biguttula (ishida), the cotton leafhopper, is a polyphagous insect pest of asia and southeast asian countries. we sequenced a mitochondrial coi gene fragment from 67 individuals of cotton leafhopper collected from 7 major cotton growing states of north, central, and south india. genetic divergence analysis of leaf hopper population across india confirmed the presence of single species. thirty haplotypes, in total, were determined across different regions of india. while populat ...	2018	28116945
selection of housekeeping genes and demonstration of rnai in cotton leafhopper, amrasca biguttula biguttula (ishida).	amrasca biguttula biguttula (ishida) commonly known as cotton leafhopper is a severe pest of cotton and okra. not much is known on this insect at molecular level due to lack of genomic and transcriptomic data. to prepare for functional genomic studies in this insect, we evaluated 15 common housekeeping genes (tub, b-tub, ef alpha, gadph, ubicf, rp13, ubiq, g3pd, vatpase, actin, 18s, 28s, tata, etf, sod and cytolytic actin) during different developmental stages and under starvation stress. we sel ...	2018	29329327
