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)
The orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae), is a chronic wheat pest worldwide. Adult S. mosellana engage in short-distance flight, but also exploit weather patterns for long-distance dispersal. However, little is known about the flight performance of S. mosellana, and the effects of the biotic and abiotic factors(More)
SMLS (Sitobion miscanthi L type symbiont) is a recently discovered aphid secondary symbiont. Using evidence extracted from 16S rRNA sequences, previous studies indicate that SMLS is the most widely distributed and most recently transferred secondary symbiont in Chinese Sitobion miscanthi populations. Here, we further investigated genetic diversity among(More)
BACKGROUND Neonicotinoids are widely used as seed treatments in wheat fields against the grain aphid (Sitobion avenae F.) in China. Due to the degradation of neonicotinoids in wheat plants, wheat aphids are more likely to be exposed to low concentrations of neonicotinoids over long periods. It is therefore expected that neonicotinoids, aside from acute(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 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)
Odorant binding proteins (OBPs) contribute to the remarkable sensitivity of the insect's olfactory system and play important roles in the olfactory recognition. The orange blossom midge, Sitodiplosis mosellana is a cereal specialist, and utilizes pheromone and host odorant as a cue for its mating and oviposition. However, OBP genes have not been largely(More)
The study aimed to investigate the characteristics and relationship between soil carbon and nitrogen transformation of artificial forestlands, which is one type of vegetation restoration in the mountain area of Southern Ningxia. Soil samples were collected every two months in a year from three forestlands, and the characteristics of soil organic carbon,(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)
Soil samples from different aspects (southern slope and northern slope) under the same vegetation in two typical vegetation zones (forest vegetation zone and steppe vegetation zone) of Yanhe basin in the loess hilly area were chosen and analyzed, in order to investigate the content and correlation of soil microbial biomass carbon (SMBC), soil microbial(More)
