Abstract

Understanding the effects of acaricides on predatory mites is essential for integrated pest management programs. Neoseiulus barkeri (Hughes) (Acari: Phytoseiidae) has been proved as a key predator of pest sucking insect pests in different crops scenarios. As a pyrrole insecticide with a new mode of action, the compatibility between chlorfenapyr and predatory mites has been rarely reported. In this study, the acute and persistent toxicity of the acaricide chlorfenapyr on the predatory mite N. barkeri fed on Tetranychus cinnabarinus (Boisduval) were assessed after direct exposure in laboratory conditions. The results of toxicity test reveal that chlorfenapyr had a higher bioactivity to T. cinnabarinus than N. barkeri. To further determine the long-term toxicity of chlorfenapyr on the biological agent N. barkeri, the sublethal effects of next generation were carried out after maternal exposure to MFRC and 1/2 MFRC. These two treatment levels prolonged the developmental time of larva, protonymph and deutonymph and reduced the longevity, oviposition days (OP), and adult pre-oviposition period (APOP) and total pre-oviposition period (TPOP) of adults. It is worth noting that although MFRC and 1/2 MFRC reduced the predation of N. barkeri to T. cinnabarinus and slowed down the population development of N. barkeri, there was a significant growth trend in the population of N. barkeri and which showed a good control effect on T. cinnabarinus. The results provide valuable information for implementing biological and chemical control strategies in integrated pest management of T. cinnabarinus.

虫螨腈对巴氏新绥螨生物学性能的毒力影响（蜱螨亚纲：植物绥螨科）

了解杀螨剂对掠食性螨的影响对害虫综合管理计划至关重要。巴氏新绥螨（newseiulus barkeri, Hughes）（蜱螨亚纲：植物绥螨科）已被证明是不同作物环境下吸虫害虫的主要捕食者。虫螨腈作为一种新型的吡咯类杀虫剂，与掠食性螨的配伍性报道较少。本研究在实验室条件下，评价了杀螨剂氯虫腈对以朱砂叶螨为食的barkeri捕食性螨的急性和持续性毒性。毒力试验结果表明，虫螨腈对朱砂螨的生物活性高于巴氏奈瑟菌。为了进一步确定氯虫腈对巴氏奈瑟菌的长期毒性，研究了母体接触MFRC和1/2 MFRC对下一代的亚致死效应。这两个处理水平均延长了幼虫、原淋巴细胞和双淋巴细胞的发育时间，降低了成虫的寿命、产卵日数（OP）、成虫的产卵前期（APOP）和总产卵前期（TPOP）。值得注意的是，虽然MFRC和1/2 MFRC减少了巴氏奈瑟螨对朱砂奈瑟螨的捕食，减缓了巴氏奈瑟螨种群的发展，但巴氏奈瑟螨种群仍有显著的增长趋势，对朱砂奈瑟螨具有良好的防治效果。研究结果为朱砂小蠹害虫综合治理中实施生物化学防治策略提供了有价值的信息。

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.
