BACKGROUND Imidacloprid has been a major neonicotinoid insecticide for controlling Aphis gossypii (Glover) (Homoptera: Aphididae) and other piercing-sucking pests. However, the resistance to imidacloprid has been recorded in many target insects. At the same time, cross-resistance of imidacloprid and other insecticides, especially neonicotinoid insecticides,(More)
BACKGROUND Fluopicolide, a novel benzamide fungicide, was registered for control of oomycete pathogens, including Phytophthora capsici. In this study, fluopicolide (5% SC) was applied in soil at rates of 1.5, 3 and 6 L ha(-1) [the normal (ND), double (DD) and quadruple dosages (QD) respectively] to investigate its transportation behaviour and control(More)
Eastern Inner Mongolia of China is a typical ecotone between sandy forests and steppe. Little is known about the effect of overgrazing on carbon loss from soil in semiarid steppe and sandy forests of the north of China. The soil carbon parameters were measured in a 10,000 ha natural reserve in eastern Inner Mongolia of China (43°30′–43°36′N,(More)
PURPOSE The purpose of this study was to investigate the effectiveness of intravitreal bevacizumab injections combined with tunable argon yellow laser photocoagulation as a treatment for adult-onset Coats' disease. METHODS We consecutively treated 3 patients suffering from Coats' disease diagnosed in adulthood with a combination of intravitreal(More)
Presynaptic 5-HT(2A) receptor modulation of glutamate release from rat cerebrocortical nerve terminals (synaptosomes) was investigated by using the 5-HT(2A/2C) receptor agonist (+/-)-1-[2,5-dimethoxy-4-iodophenyl]-2-aminopropane (DOI). DOI potently inhibited 4-aminopyridine (4AP)-evoked glutamate release. Involvement of presynaptic 5-HT(2A) receptors in(More)
BACKGROUND Spinosad is increasingly used in pest management programmes, and resistance to it has been detected in recent years. However, there is no report on the susceptibilities of field populations of Helicoverpa armigera (Hübner) from China. Furthermore, the impact of spinosad on metabolic enzymes in this pest remains unknown. RESULTS Four populations(More)
Myostatin is a well-known negative regulator of skeletal muscle growth. Inhibition of myostatin activity results in increased muscle mass. Myostatin propeptide, as a myostatin antagonist, could be applied to promote meat production in livestock such as pigs. In this study, we generated a transgenic mouse model expressing porcine myostatin propeptide under(More)
BACKGROUND Helicoverpa armigera (Hübner) is one of the most important pests in many countries. Spinosad is used widely for the control of pests, but there is sparse information available regarding its sublethal effects on H. armigera. Here, the authors attempt to investigate the sublethal effects of spinosad on H. armigera in order to reveal the negative,(More)
The fitness cost of spinosad resistance was investigated in the cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). Laboratory experiments were conducted to compare relative fitness of H. armigera between the spinosad-susceptible and -resistant strains. During the experiments, the average development periods of the resistant strain were(More)
