| identification of a sex pheromone of the chrysanthemum lace bug corythucha marmorata (hemiptera: tingidae). | although the nymphs of corythucha marmorata form clusters on the undersides of host plant leaves, as frequently observed for hemiptera, the adults are scattered in the vicinity of the nymph population. by investigating the biological activities of volatile secretions from the adult, we found that the secretions activated male mounting behaviour. a chemical analysis revealed that borneol was a common component of the secretions from both sexes. the absolute configuration of the natural product wa ... | 2017 | 28779116 |
| parallel environmental factors drive variation in insect density and plant resistance in the native and invaded ranges. | geographic variation in the traits of a species is shaped by variation in abiotic conditions, biotic interactions, and evolutionary history of its interactions with other species. we studied the geographic variation in the density of the lace bug, corythucha marmorata, and the resistance of tall goldenrod solidago altissima to the lace bug herbivory in their native range in the united states and invaded range in japan. we conducted field surveys and reciprocal transplant experiments to examine w ... | 2017 | 28771704 |
| alarm pheromone activity of nymph-specific geraniol in chrysanthemum lace bug corythucha marmorata against adults and nymphs. | the exotic insect pest corythucha marmorata (uhler) is increasingly spreading in japan using the weed solidago canadensis l. as a major host plant. the nymphs form colonies on the backs of leaves where they crowd together; however, aggregation does not occur in the adults. when an individual nymph is crushed using a needle tip and further the needle tip covered with the nymph's bodily fluids is moved slowly toward the center of the crowd, the surrounding nymphs display an escape behavior and the ... | 2015 | 26594742 |
