The ladybird and the green lacewing have shown potential for use in augmentative biological control of mealybug pests in greenhouse crops. In the context of combining these predators within an integrated pest management system, the risk of negative intraguild interactions between both predators was evaluated in a laboratory setting. Different life stages of either predator were confronted in petri dish arenas containing a leaf, and after 24 h the incidence and direction of intraguild predation (IGP) was recorded for each combination. The effect of adding nymphs or eggs as extraguild prey on the level of IGP was also studied. IGP was frequently observed between the two predator species and was asymmetrical in favour of in most cases. The presence of extraguild prey reduced the number of IGP events between the predators to a similar extent. The relevance of the observed intraguild interactions for the combined use of these predators in protected cultivation is discussed.
瓢虫和草蛉已显示出在温室作物中对粉虱害虫进行增殖性生物防治的潜力。在将这些捕食性天敌组合纳入综合害虫管理系统的背景下，在实验室环境中评估了两种捕食性天敌之间负面种内互作的风险。在含有一片叶子的培养皿试验场中，使任一捕食性天敌的不同生命阶段相互接触，24小时后，记录每种组合的种内捕食（IGP）发生率和方向。还研究了添加若虫或卵作为种外猎物对IGP水平的影响。在两种捕食性天敌物种之间经常观察到IGP，并且在大多数情况下是不对称的，有利于[此处原文缺失信息]。种外猎物的存在使捕食性天敌之间的IGP事件数量减少到类似程度。讨论了观察到的种内互作对这些捕食性天敌在设施栽培中联合使用的相关性。
