摘要

我们进行了实验室生物测定，以评估噻虫嗪作为谷物保护剂对Ⅳ级和Ⅴ级成虫的功效。对五种浓度（0.1、0.5、1、2 和 4 ppm）和四种商品（小麦、玉米、水稻和大麦）进行了评估。在接触噻虫胺 7、14 和 21 天后记录死亡率，在接触噻虫胺 65 天后评估后代产量。噻虫嗪在浓度较高时更有效，是最易感的品种。令人惊讶的是，在大多数受测商品中，成虫数量为 154.3 头/瓶时，后代产量最高，而在百万分之 2 和百万分之 4 的浓度下，没有观察到后代产量。总之，噻虫嗪可以对小麦、玉米、水稻和大麦中的主要储藏产品昆虫种类提供足够的控制水平。

Efficacy of thiamethoxam against Sitophilus oryzae, Tribolium confusum and Rhyzopertha dominica: The effect of commodity and dose rate

Laboratory bioassays were conducted to evaluate the efficacy of thiamethoxam as a grain protectant against Sitophilus oryzae, Tribolium confusum and Rhyzopertha dominica adults. Five concentrations (0.1, 0.5, 1, 2, and 4 ppm) and four commodities (wheat, maize, rice, and barley) were evaluated. Mortality rates were recorded after 7, 14, and 21 d and progeny production was assessed 65 d after exposure. Thiamethoxam was more effective at higher concentrations and S. oryzae was the most susceptible species. Surprisingly, the highest progeny production was recorded for S. oryzae with 154.3 adults/vial, while no progeny production was observed for T. confusum at 2 and 4 ppm in most of the commodities tested. To conclude, thiamethoxam can provide an adequate level of control against major stored-product insect species in wheat, maize, rice and barley.

期刊介绍： The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics: -Abiotic damage- Agronomic control methods- Assessment of pest and disease damage- Molecular methods for the detection and assessment of pests and diseases- Biological control- Biorational pesticides- Control of animal pests of world crops- Control of diseases of crop plants caused by microorganisms- Control of weeds and integrated management- Economic considerations- Effects of plant growth regulators- Environmental benefits of reduced pesticide use- Environmental effects of pesticides- Epidemiology of pests and diseases in relation to control- GM Crops, and genetic engineering applications- Importance and control of postharvest crop losses- Integrated control- Interrelationships and compatibility among different control strategies- Invasive species as they relate to implications for crop protection- Pesticide application methods- Pest management- Phytobiomes for pest and disease control- Resistance management- Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
