BACKGROUND
The evaluation of lethal and sublethal effects is of great importance for a complete assessment of the total impact of chemical compounds upon pest populations and the development of management strategies. In this study, we evaluated the lethal and sublethal effects of different synthetic and botanical products on the broad mite Polyphagotarsonemus latus (Banks), a major pest of Capsicum annuum L. and other crops.
RESULTS
Abamectin had the highest lethal effect on P. latus, followed by spiromesifen, azadirachtin, neem oil and nitrogen fertiliser + citric acid. The sublethal effects of the products were indicated by the influence on mite population growth, affecting the numbers of females, males, larvae, pupae and eggs. Furthermore, a negative instantaneous rate of increase in P. latus and repellent effects were observed.
CONCLUSION
The lethal and sublethal effects of abamectin, spiromesifen, azadirachtin and neem oil significantly affect P. latus population growth, as well as causing repellence to this mite on C. annuum, and they should be considered in the integrated pest management of this mite. © 2017 Society of Chemical Industry.
背景
评估致死和亚致死效应对于全面评估化合物对害虫种群的总影响以及制定管理策略非常重要。在这项研究中，我们评估了不同合成和植物产品对辣椒和其他作物上的重要害虫茶黄螨（Polyphagotarsonemus latus）的致死和亚致死效应。
结果
阿维菌素对茶黄螨的致死效果最高，其次是螺虫乙酯、印楝素、苦皮藤素和氮肥+柠檬酸。产品的亚致死效应表现为对螨类种群增长的影响，影响雌螨、雄螨、幼螨、蛹和卵的数量。此外，还观察到茶黄螨的瞬时增长率为负，以及驱避作用。
结论
阿维菌素、螺虫乙酯、印楝素和苦皮藤素的致死和亚致死效应对茶黄螨种群增长有显著影响，并且对辣椒上的这种螨类有驱避作用，因此在这种螨类的综合虫害管理中应予以考虑。 © 2017 英国化学学会。
