苹果蠹蛾（CM）和东方果树蠹蛾（OFM）是世界范围内非常重要的果园害虫，特别是在澳大利亚的维多利亚，这两个物种都损害梨果。个别CM和OFM已成功地控制信息素介导的交配中断，但治疗梨果与完全注册率的两个人的手应用分配器CM和OFM可能是不经济的种植者。在喷洒杀虫剂的地块中进行的三个季节的田间试验一致表明，设计用于破坏CM和OFM的双Isomate C/OFM TT分配器与Isomate CTT和Isomate OFM罗索分配器分别单独应用于梨中以控制CM和OFM一样有效。双和个体物种分配器减少蛾捕获和水果损害到类似的程度。结果表明，采用Isomate C/OFM TT双药剂联合防治梨CM和OFM比单独使用药剂更经济，因为双药剂的价格和施用成本约为单独药剂的一半。
Codling moth (CM) and oriental fruit moth (OFM) are very important orchard pests worldwide, and particularly in Victoria, Australia, where both species damage pome fruit. Individually CM and OFM have been controlled successfully by pheromone-mediated mating disruption, but treatment of pome fruit with full registered rates of two individual hand-applied dispensers for CM and OFM could be uneconomical for growers. Field trials conducted over three seasons in plots sprayed with insecticides consistently demonstrated that dual Isomate C/OFM TT dispensers, designed to disrupt both CM and OFM, were as effective as Isomate CTT and Isomate OFM Rosso dispensers applied individually in pears for control of CM and OFM respectively. The dual- and individual-species dispensers reduced moth catches and fruit damage to a similar degree. The results suggest that combined control of CM and OFM in pears by applying dual Isomate C/OFM TT dispensers at the full-recommended rate of 500 dispensers per hectare will be more economical than use of individual species dispensers, because the price and application cost of dual dispenser is about half that for individual dispensers.
