(Pinus sylvestris L.) trees were grown in open-top chambers in the presence of an elevated temperature or CO2 concentration, or both. The elevated temperature treatment was administered year-round for 3 years. The CO2 treatment was applied between April 15 and September 15 for 2 years. The photosynthetic responses of 1and 2-year-old needles to varying(More)
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)
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)
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)
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)
Lactoferrin (LF), an 80 kDa iron binding glycoprotein, was effective in the control of gray mould caused by Botrytis cinerea on tomato. LF strongly inhibited spore germination and germ tube elongation of B. cinerea in vitro, especially at 100 mg/L. When viewed by fluorescence microscopy following staining with propidium iodide, the membrane integrity of B.(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)
BACKGROUND Thiacloprid is a chloronicotinyl insecticide that is quite effective against sucking insects. In this study, when thiacloprid was applied at two different rates (normal rate 15 kg ha(-1) , double rate 30 kg ha(-1) ), the systemic distribution and residue of thiacloprid as well as its control effect against whitefly (Bemisia tabaci) were(More)
