Predatory mites, particularly those of the Phytoseiidae family, play a key role in sustainable pest management by reducing pest populations and minimizing reliance on chemical pesticides. Amblyseius largoensis (Muma) (Acari: Phytoseiidae) is a generalist predator, with great potential for controlling noxious agricultural pests. However, large-scale rearing of A. largoensis remains a challenge due to the lack of an efficient mass-production system. This study aimed to select a factitious prey species from the order Astigmata that could support the mass-rearing of A. largoensis. Four Astigmata species (Carpoglyphus lactis L., Thyreophagus crasentiseta Barbosa, OConnor & Moraes, Tyrophagus putrescentiae Schrank, and Glycycometus aff. molitor Volgin & Akimov) were evaluated for their ability to sustain the predator's survival, development, and reproduction. Tetranychus urticae Koch, a well-established natural prey, was used as a control. Bioassays assessed the growth rates of A. largoensis when fed exclusively on each prey species. The results showed that C. lactis supported survival and reproduction rates comparable to T. urticae, with an intrinsic growth rate favorable for mass-rearing. The other prey proved unsuitable for A. largoensis mass-rearing. Additionally, C. lactis offers practical advantages as it is easy to rearing, thrives on simple and inexpensive food sources, and allows for continuous predator production. This study highlights the potential of C. lactis as a viable factitious prey for the large-scale production of A. largoensis, contributing to the diversification of biological control strategies. Future research should focus on optimizing rearing protocols and field evaluation to validate the effectiveness of A. largoensis as a biocontrol agent in tropical and subtropical regions.
捕食螨，尤其是植绥螨科的捕食螨，通过减少害虫数量和最大限度地减少对化学农药的依赖，在可持续害虫管理中发挥着关键作用。拉哥钝绥螨（Muma）（蜱螨亚纲：植绥螨科）是一种多食性捕食者，在控制有害农业害虫方面具有巨大潜力。然而，由于缺乏高效的大规模生产系统，大规模饲养拉哥钝绥螨仍然是一项挑战。本研究旨在从粉螨目中选择一种替代猎物物种，以支持拉哥钝绥螨的大规模饲养。评估了四种粉螨物种（乳果螨、厚角食酪螨、腐食酪螨和嗜甜螨）维持捕食者生存、发育和繁殖的能力。以一种常见的天然猎物二斑叶螨作为对照。生物测定评估了拉哥钝绥螨仅以每种猎物物种为食时的生长速率。结果表明，乳果螨支持的生存和繁殖率与二斑叶螨相当，其内在增长率有利于大规模饲养。其他猎物被证明不适用于拉哥钝绥螨的大规模饲养。此外，乳果螨具有实际优势，因为它易于饲养，能在简单且廉价的食物来源上茁壮成长，并能持续生产捕食者。本研究强调了乳果螨作为拉哥钝绥螨大规模生产的可行替代猎物的潜力，有助于生物防治策略的多样化。未来的研究应侧重于优化饲养方案和田间评估，以验证拉哥钝绥螨作为热带和亚热带地区生物防治剂的有效性。
