The drosophilid fly Drosophila suzukii is an invasive pest that has recently started threatening fruit production in Europe. In contrast to many other fruit flies, D. suzukii is able to lay eggs in ripening and mature fruits where larvae develop, rendering fruits unmarketable. This preference for ripening fruit requires pest control shortly before harvest, implying a high risk of residues on the fruit if synthetic insecticides are used. As the current management practices largely rely on chemical control, the need for alternative solutions has emerged. Here, we review the studies published up to now on the efficacy of natural compounds against D. suzukii. Several natural compounds were identified that act as repellents, contact or ingestion toxicants, fumigants, ovicides or oviposition deterrents. The most promising compounds of each group were (i) essential oils (EOs) such as the EO of thyme or its major ingredient thymol which repelled flies from fresh fruits for at least 24 h; (ii) Leptospermum ericoides and L. scoparium EOs, which expressed contact toxicity at a LD50 < 1.2 μg/fly; (iii) the combination of erythritol and sucrose, which was a potent ingestion toxicant against adults and (iv) a chitinase from Euphorbia characias against larvae (both of the latter two resulted in 100% mortality); (v) the EO ingredients perilla aldehyde, geranial and neral showed the highest insecticidal activities as fumigants (LC50 < 1.52 mg/l air for males and 2.6 mg/l air for females) and (vi) powdered sulphur was reported to be the most efficient oviposition deterrent, reducing the number of eggs deposited into the fruits by 76%. To enable a wider use of the natural compounds in sustainable agriculture, more information on (i) potential effects on non-target organisms, (ii) field performance and (iii) life cycle analyses results is currently needed.

用于控制果蝇铃木的天然化合物。回顾

果蝇蝇果蝇是一种入侵性害虫,最近开始威胁到欧洲的水果生产。与许多其他果蝇相反,D。suzuk ii能够在幼虫发育的成熟果实中产卵,从而使果实无法销售。这种对果实成熟的偏爱要求在收获前不久进行害虫防治,这意味着如果使用合成杀虫剂,则水果上残留的风险很高。由于当前的管理实践很大程度上依赖于化学控制,因此出现了对替代解决方案的需求。在这里,我们回顾了迄今为止发表的有关天然化合物对铃木D.效力的研究鉴定出几种天然化合物,可作为驱避剂,接触或摄入的有毒物质,熏蒸剂,杀卵剂或产卵抑制剂。每组中最有前途的化合物是(i)精油(EOs),如百里香EO或其主要成分百里酚,它们可以驱除新鲜水果中的果蝇至少24小时;(ii)Leptospermum ericoidesL. scoparium EOs,在LD 50  <1.2μg/蝇时表现出接触毒性;(iii)赤藓糖醇和蔗糖的混合物,这是对成年人有效的食入毒物;以及(iv)大戟属的几丁质酶对抗幼虫(后两者均导致100%的死亡率);(v)EO成分紫苏醛,香叶醛和神经醛作为熏蒸剂具有最高的杀虫活性( 雄性LC 50 <1.52 mg / l空气和雌性2.6 mg / l空气),并且(vi)据报告粉状硫是最有效的产卵威慑力,可将沉积在水果中的卵数减少76%。为了使天然化合物在可持续农业中得到更广泛的使用,目前需要有关(i)对非目标生物的潜在影响,(ii)田间表现和(iii)生命周期分析结果的更多信息。
