西花蓟马(Frankliniella ococcuentalis)是园艺作物的害虫,包括商业草莓(Fragaria x ananassa)。控制是具有挑战性的,因为某些种群对杀虫剂有抗药性,在草莓中,现在依赖于生物控制的应用。然而,这种方法并不总是成功的。生物控制的优势种群压倒生物控制。我们研究了是否有针对性的光谱修改包层材料可以减少F的数量。五种紫外线衰减塑料膜材料在三个6周的半场隧道实验中进行了测试,实验中含有草莓植物。将实验室培养的寄生虫引入隧道中,并记录随后在草莓花中发育的数量。限制对作物的UV-A辐射显著减少了成虫和幼虫的数量。草莓花中的仙人掌。与UVopen(对照)薄膜相比,在UV 350、UV 370、UV 400和UV 430衰减薄膜中,花中成虫(和幼虫)的数量分别减少了42(47)%、54(41)%、70(73)%和82(73)%。然而,没有观察到任何损害草莓果实的膜处理。有时候草莓里的数字。减少F.在作物中使用化学农药可能会使其他非化学控制策略的使用更加成功。
Frankliniella occidentalisis a pest of horticultural crops, including commercial strawberry (Fragaria x ananassa). Control is challenging because certain populations are resistant to insecticides and, in strawberry, now relies on the application of biocontrols. However, this approach is not always successful ifF. occidentalispopulations overwhelm biocontrols. We investigated whether targeted spectral modifications to cladding materials could reduce numbers ofF. occidentalis, in strawberry flowers.Five UV‐attenuating plastic‐film materials were tested in three, 6‐week, semi‐field tunnel experiments containing strawberry plants.F. occidentaliswere introduced into tunnels from a laboratory culture and subsequent numbers that developed in strawberry flowers were recorded.Limiting UV‐A radiation to the crop significantly reduced the numbers of adult and larvalF. occidentalisin strawberry flowers. The numbers of adult (and larvae) in flowers were reduced by 42 (47)%, 54 (41)%, 70 (73)%, and 82 (73)% in UV350, UV370, UV400, and UV430‐attenuating films, respectively, compared with the UVopen (control) film. However, no damage to strawberry fruits was observed regardless of the film treatment.Incorporating UV‐attenuating films as tunnel cladding can suppressF. occidentalisnumbers in strawberry. Reducing populations ofF. occidentalisin crops is likely to enable the more successful use of other non‐chemical control strategies.
