BACKGROUND Many insects enter a developmental arrest (diapause) that allows them to survive harsh seasonal conditions. Despite the well-established ecological significance of diapause, the molecular basis of this crucial adaptation remains largely unresolved. Sitodiplosis mosellana (Gehin), the orange wheat blossom midge (OWBM), causes serious damage to(More)
Surveys based on the density of the adult wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), were conducted at ground level and at heights between 10 and 75 m in Xushui county (39.02 °N, 115.65 °E), Hebei province, China, in 2011. The HYSPLIT-4 model was used to analyze the possible dispersion trajectories and distances of S. mosellana(More)
The scarab beetle, Anomala corpulenta Motschulsky, is a metallic iridescent species that selectively reflects left-circularly polarized light and possesses a brilliant metallic green appearance. We hypothesized that A. corpulenta use the green circularly polarized signal for conspecific communication, specifically sexual signaling and mate selection. To(More)
The wheat midge, Sitodiplosis mosellana, is an important pest in Northern China. We tested the hypothesis that the population structure of this species arises during a range expansion over the past 30 years. This study used microsatellite and mitochondrial loci to conduct population genetic analysis of S. mosellana across its distribution range in China. We(More)
Geostatistis methods were adopted to analyze the spatial pattern of Sitodiplosis mosellana (Diptera: Cecidomyiidae) at its different development periods and of its egg parasitoids mixed population (Tetrastichus sp. and Platygaster error; Hymoneptera: Eulophidae and Platygastridae). The aggregated spatial arrangements for S. mosellana cocoon, adult, and(More)
