| sex pheromone desaturase functioning in a primitive ostrinia moth is cryptically conserved in congeners' genomes. | (e)-11- and (z)-11-tetradecenyl acetate are the most common female sex pheromone components in ostrinia moths. the ?11-desaturase expressed in the pheromone gland (pg) of female moths is a key enzyme that introduces a double bond into pheromone molecules. a single ?11-desaturase of ostrinia nubilalis, onubz/e11, has been shown to produce an ~7:3 mixture of (e)-11- and (z)-11-tetradecenoate from the substrate tetradecanoate. in contrast, the sex pheromone of ostrinia latipennis, a primitive speci ... | 2011 | 21444802 |
| variation in mitochondrial coii gene sequences among two species of japanese knotweed-boring moths, ostrinia latipennis and o. ovalipennis (lepidoptera: crambidae). | the ostrinia latipennis group contains two species, o. latipennis (warren) and o. ovalipennis ohno. these two species commonly utilize perennial knotweeds (fallopia spp.) as their host plants, which are serious invasive weeds in europe and north america. ostrinia latipennis is widely distributed across north-east asia including japan whereas o. ovalipennis is restricted to north japan (hokkaido is.) and highland areas of central japan (nagano prefecture in honshu is.). to estimate the phylogenet ... | 2006 | 16768812 |
| leaf epicuticular wax chemicals of the japanese knotweed fallopia japonica as oviposition stimulants for ostrinia latipennis. | extraction, fractionation, and gas chromatography-mass spectrometry analyses guided by bioassays have shown that n-alkanes and free fatty acids in leaf epicuticular wax of the japanese knotweed fallopia (reynoutria) japonica stimulate oviposition in the far-eastern knotweed borer, ostrinia latipennis (lepidoptera: crambidae). n-alkanes made up 48.1% of the total amount of epicuticular wax, and their carbon chain length was in the c(16)-c(33) range, with n-nonacosane (n-c(29)) most abundant, foll ... | 2006 | 16586039 |
| physiological adaptation of the asian corn borer ostrinia furnacalis to chemical defenses of its host plant, maize. | a number of gramineous plants such as maize contain cyclic hydroxamic acids (chx) that are toxic to many herbivores. among the ostrinia species found in japan, the asian corn borer ostrinia furnacalis is the only one that utilizes maize, a gramineous plant. we used o. furnacalis and two congeners, ostrinia scapulalis and ostrinia latipennis, to obtain insights into the physiological adaptation of o. furnacalis to chx. when an artificial diet containing a low concentration (0.3mg/g diet) of chx w ... | 2010 | 20435041 |
