Abstract

Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae) is an effective biocontrol agent used against whiteflies, thrips, and spider mites in crops. This study assessed the effects of an acaricide of abamectin + bifenazate mixture on the life tables of native (NP) and acaricide-resistant (S6) populations of A. swirskii under controlled conditions in growth chambers set to 28 ± 1 °C, 80 ± 5 % relative humidity, and a 16:8 h light:dark photoperiod. The S6 population, with 25-fold resistance to abamectin+bifenazate, was developed from NP through six selections. Life history and population growth parameters were analyzed under untreated and acaricide-treated conditions at the recommended concentration. Under untreated conditions, developmental durations were similar between S6 and NP, but S6 females had longer lifespans, higher fecundity, and longer oviposition periods. The intrinsic rate of increase (r), net reproductive rate (R₀), and finite rate of increase (λ) were not significantly different between S6 and NP. Under acaricide-treated conditions, S6 females had longer lifespans and oviposition periods, with significantly higher fecundity. The reproductive parameters R₀, r, and λ were higher in S6 than NP. These results suggest that resistance to abamectin and bifenazate did not negatively impact the fitness components of A. swirskii, providing valuable insights for integrated pest management (IPM) programs.

实验室条件下威氏钝绥螨与抗阿维菌素和联苯肼种群的年龄、阶段、两性生命表分析

威氏钝绥螨（Amblyseius swirskii Athias-Henriot）是一种有效的生物防治剂，用于防治作物中的白蝇、蓟马和蜘蛛螨。本研究在28±1℃，80±5%相对湿度，16:8 h光照周期的条件下，研究了杀螨剂阿维菌素+联苯肼混合剂对威氏小蠊原生种群（NP）和抗螨种群（S6）生命表的影响。S6群体对阿维菌素+联苯肼耐药25倍，由NP经过6次选育而成。在推荐浓度下，分析了未处理和杀螨剂处理条件下的生活史和种群生长参数。在未经处理的条件下，S6和NP的发育持续时间相似，但S6雌性寿命更长，繁殖力更高，产卵期更长。内在增长率(r)、净繁殖率（R0）和有限增长率（λ）在S6和NP之间无显著差异。在杀螨剂处理的条件下，S6雌虫的寿命和产卵期更长，繁殖力显著提高。S6的繁殖参数R0、r和λ均高于NP。这些结果表明，对阿维菌素和联苯肼的抗性并未对黄纹田鼠的适合度成分产生负面影响，为害虫综合治理（IPM）计划提供了有价值的见解。

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.
