In conservation agriculture, slugs are considered significant pests and their monitoring is a key option in the integrated pest management framework. Together with molluscicide applications, predators such as ground beetles can offer a tool for slug control in the field. Through the evaluation of slug and ground beetle monitoring strategies, this work compared their presence in conventional and conservation agricultural plots. The invasive Deroceras invadens was the dominant slug species to occur in all sampling periods. Among Carabidae, Poecilus cupreus and Pterostichus melas were the most abundant species, and Bembidion spp., Brachinus spp., and Harpalus spp. were also common. Beer-baited pitfall traps, whatever their alcoholic content, caught more slugs and ground beetles than wooden boards used as shelters. Slugs were more abundant in conventional plots than in conservation plots, possibly due to the lower presence of natural enemies such as ground beetles. Despite possible impacts on Carabidae, beer-baited pitfall traps should be considered a useful tool for slug monitoring and for the planning of molluscicide applications. Soil management such as minimum- or no-tillage and the presence of cover crops are important elements influencing both slug and ground beetle presence, possibly playing a key role in the maintenance of natural enemy populations.

在常规和保护性农业生态系统的可持续虫害控制框架内,对ug虫的监测及其对地面甲虫群落的影响。

在保护性农业中,被认为是重要的害虫,其监测是病虫害综合治理框架中的关键选择。与杀虫剂一起使用,诸如甲虫之类的捕食者可以为野外的控制提供工具。通过评估of和地面甲虫的监测策略,这项工作比较了它们在常规农田和保护性农田中的存在。在所有采样期间,入侵的Deroceras入侵是主要的类。在金龟科中,Poecilus cupreusPterostichus melas是最丰富的物种,Bembidion spp。,Brachinus spp。和Harpalus spp。也很常见。啤酒诱饵陷阱,无论其酒精含量如何,都比用作庇护所的木板捕获了更多的和地面甲虫。与自然保护区相比,常规土地上的含量更高,这可能是由于天敌(例如地甲虫)的存在率较低。尽管可能会对Carabidae造成影响,但应将啤酒诱饵陷阱诱捕器视为对进行监测和规划杀虫剂应用的有用工具。少耕或免耕和覆盖作物等土壤管理是影响和地面甲虫存在的重要因素,可能在维持天敌种群方面发挥关键作用。
