蚜虫是世界上许多农作物的主要害虫蚜虫的增强生物防治中最重要的捕食者之一。成年雌性非常有效地在相对长的范围内（最多45 m）定位蚜虫侵染，并在蚜虫菌落附近或内部沉积卵。捕食性幼虫是蚜虫通才，以几种重要的农业蚜虫为食。这种生物防治剂在农业系统中的成功使用取决于几种生物和非生物因素。在生物因素中，蚜虫种类，植物结构，种间竞争和公会内捕食可能会严重影响捕食者的种群动态。关键的非生物条件包括日长（高于防止滞育的关键阈值），作物交配点的可用性，温度（高于15°C以便产卵），空气相对湿度（70％以上）和化up场所的可用性。尽管已经报道了自然发生或释放种群的开放田间作物取得了一些成功，但商业释放主要用于受保护的作物。优化的出苗箱结合了为成年人提供食物来源，与温室环境中最近发生的技术进步相结合，对田间作物营养生态学的洞察力以及对遗传变异性的探索，被提议作为改善收养和功效的未来方向的蚜虫在作物保护中的作用。©2018年化学工业协会

Optimizing aphid biocontrol with the predator Aphidoletes aphidimyza, based on biology and ecology

Aphidoletes aphidimyza is one of the most important predators used in the augmentative biological control of aphids, key pests of many crops worldwide. Adult females are very efficient in locating aphid infestations over a relatively long range, up to 45 m, and deposit eggs near or within aphid colonies. The predatory larvae are aphid generalists preying on several agriculturally important aphid species. The successful use of this biocontrol agent in agricultural systems depends on several biotic and abiotic factors. Among biotic factors, aphid species, plant structure, interspecific competition and intraguild predation may significantly impact the predator´s population dynamics. Key abiotic conditions include day lengths (above a critical threshold to prevent diapause), availability of mating sites in the crop, temperature (above 15 °C to enable egg laying), air relative humidity (above 70%) and availability of pupation sites. Although several successes have been reported in open field crops with naturally occurring or released populations, commercial releases are primarily used in protected crops. Optimized emergence boxes combining provisioning of food sources for the adults, integration with the technological advances that occurred in the greenhouse environment lately, insights into the nutritional ecology in open field crops and exploration of the genetic variability are proposed as future directions to improve adoption and efficacy of A. aphidimyza in crop protection. © 2018 Society of Chemical Industry
