Abstract

Studies of oriental fruit moth (OFM), Grapholita molesta (Busck), and codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), both important pests of pome fruit, evaluated the addition of low‐intensity light‐emitting diode (LED) to delta traps baited with 3 commercial monitoring lures. Studies were conducted in 9 orchards treated with and without sex pheromone mating disruption for one or both species. OFM was monitored with a two‐part pheromone/kairomone lure (OFM Combo Dual), while CM was monitored with either a two‐part kairomone lure (CM Dual 4 K) or a sex pheromone lure (CM PH). Both pests were monitored with or without the addition of three types of a low power LED light with peak intensity at 395 (UV‐A), 458 (blue), and 516 (green) nm. The UV‐A LED was found to be the most effective among the three lights for OFM. Unexpectedly, traps with the OFM Combo Dual lure plus UV‐A LED caught similar numbers of CM as traps baited with the CM Dual 4 K and CM PH lures alone. They also caught other pest species, such as oblique banded leafroller (OBLR), Choristoneura rosaceana (Harris), and peach twig borer (PTB), Anarsia lineatella (Zeller). Interestingly, in different trials the OFM Combo Dual combined with UV‐A LED light caught significantly more OFM and/or CM females compared to the OFM Combo Dual lure without light, opening the perspective for a female‐oriented monitoring and for a “female removal” management approach of these pests. The development of inexpensive, dual‐modality traps adding a light stimulus to a pheromone/kairomone lure may reduce monitoring costs in orchards with multiple moth pests, improving the trapping efficiency.
使用双性信息素/凯洛蒙引诱剂和紫外线 A 光灯诱捕器同时有效监测 Grapholita molesta 和 Cydia pomonella(鳞翅目:蝶科)的情况
对东方果蠹(OFM)Grapholita molesta (Busck)和苹果蠹蛾(CM)Cydia pomonella (L.)(鳞翅目:Tortricidae)这两种重要的梨果害虫的研究评估了在使用 3 种商业监测诱饵的三角诱捕器中添加低强度发光二极管(LED)的效果。研究在 9 个果园中进行,对其中一种或两种害虫分别进行了性信息素交配干扰处理和未进行交配干扰处理。使用由信息素/凯洛蒙两部分组成的诱饵(OFM Combo Dual)监测 OFM,而使用由凯洛蒙两部分组成的诱饵(CM Dual 4 K)或性信息素诱饵(CM PH)监测 CM。监测这两种害虫时,可使用或不使用三种类型的低功率 LED 灯,其峰值强度分别为 395(紫外线-A)、458(蓝色)和 516(绿色)纳米。结果发现,UV-A LED 是三种灯中对 OFM 最有效的一种。出乎意料的是,装有 OFM Combo 双诱饵和 UV-A LED 的诱捕器捕获的 CM 数量与单独装有 CM Dual 4 K 和 CM PH 诱饵的诱捕器相似。它们还能捕捉到其他害虫,如斜带卷叶螟(OBLR),Choristoneura rosaceana(Harris)和桃树枝蛀虫(PTB),Anarsia lineatella(Zeller)。有趣的是,在不同的试验中,与不发光的 OFM Combo Dual 引诱剂相比,OFM Combo Dual 与 UV-A LED 灯相结合能捕捉到更多的 OFM 和/或 CM 雌虫,这为以雌虫为导向的监测和这些害虫的 "雌虫清除 "管理方法开辟了前景。开发廉价的双模式诱捕器,在信息素/凯洛蒙诱饵中加入光刺激,可降低多种蛾类害虫果园的监测成本,提高诱捕效率。
