gut symbiotic bacteria of the genus burkholderia in the broad-headed bugs riptortus clavatus and leptocorisa chinensis (heteroptera: alydidae).	the japanese common broad-headed bugs riptortus clavatus and leptocorisa chinensis possess a number of crypts in the posterior region of the midgut, whose lumen contains a copious amount of bacterial cells. we characterized the gut symbiotic bacteria by using molecular phylogenetic analysis, light and electron microscopy, in situ hybridization, and pcr-based detection techniques. restriction fragment length polymorphism analysis of 16s rrna gene clones suggested that a single bacterium dominated ...	2005	16000818
mortality factors of eggs of leptocorisa chinensis (hemiptera: alydidae) in rice fields.	to clarify factors causing mortality of leptocorisa chinensis dallas (hemiptera: alydidae) eggs in rice fields, sentinel egg masses were exposed for seven days in two rice, oryza sativa l. (poaceae), fields. an insecticide was sprayed to remove natural enemies in one-half of each field before exposing egg masses to predation. an egg mass containing 14 eggs was glued to a plastic label, and 21 egg masses each were placed in the sprayed and unsprayed control plots. during exposure, the number of h ...	2006	16686134
sexual differences in the crucial environmental factors for the timing of postdiapause development in the rice bug leptocorisa chinensis.	although the regulation of reproductive diapause by environmental factors has been extensively studied in a variety of insect orders, sexual differences in the regulation of diapause are still poorly understood. we examined the effects of environmental factors including photoperiod, temperature and food on the regulation of reproductive diapause in both sexes of the rice bug leptocorisa chinensis (dallas) (hemiptera: alydidae) in the laboratory and under natural conditions. there was no signific ...	2007	17572437
regulation of gonad development and respiratory metabolism associated with food availability and reproductive diapause in the rice bug leptocorisa chinensis.	food has an influence on many life history traits related to dormancy in insects. in our previous study with the rice bug leptocorisa chinensis (dallas) (hemiptera: alydidae), diapausing females transferred to conditions physically favorable for promoting the gonad development required food intake to resume gonad development, whereas males did not. these differences in response to food between males and females lead to two questions: (1) was diapause in the starved females completed? (2) were th ...	2008	18164027
attractant pheromone for male rice bug,leptocorisa chinensis: semiochemicals produced by both male and female.	gc profiles of the airborne volatiles produced by adult males and females of the rice bug,l. chinensis showed no qualitative chemical dimorphism. however, gc-ead experiments showed that eight of the compounds elicited strong responses in male and female antennae. ruling out alarm pheromone and compounds that were not found in the whole-body extracts of the bugs, four compounds remained to be tested as possible attractants. in field experiments, the whole mixture or tertiary blends were not attra ...	1996	24226246
