| phylogeography of the rice spittle bug (callitettix versicolor) implies two long-term mountain barriers in south china. | south china is a region of remarkable topographic complexity. however, the impact of climate fluctuations in the pleistocene on the local fauna and especially insects has not been extensively studied. we integrated mitochondrial dna (mtdna) and microsatellite data of the rice spittle bug, callitettix versicolor, to determine the genetic structure, potential biogeographic barriers, and historical demography of this species. the mtdna data revealed two distinct lineages (western and eastern) congr ... | 2016 | 27927096 |
| identification of a self-regulatory pheromone system that controls nymph aggregation behavior of rice spittlebug callitettix versicolor. | nymphs of many spittlebug species are known to aggregate in one spittle mass, a behavior which greatly benefits the survival of the developing nymphs. little is known, however, about the precise mechanisms that induce and regulate aggregation. here, we investigated the aggregation behavior of nymphs of the rice spittlebug callitettix versicolor, and analyzed the chemical composition of spittle masses. | 2015 | 25987889 |
