此项研究工作是在非隔离的禁用杀虫剂的商品果园进行的。目的是为了控制苹果蠹蛾[Cydia pomonetla(L)]梨小食心虫〔Grapholithamolesta(Busck)];苹小食心虫〔 GPrunivora( Walsh)];红带卷叶蛾〔 Argyrotaeina velut-lnana(Walker)];蔷薇卷叶蛾[Choristoneura rosaceana( Harris)]和 三条卷叶蛾(Pandemis Limitata(Robinson)];利用性外激素(sex Pheromon,亦称性信息素)诱捕器对这六种害虫进行混合诱捕(Mass traping),在高、低两种诱捕密度下,果实遭受这六种害虫的为害愈来愈烈,卷叶蛾类的为害超出了商品化果实生产所能忍受的程度。在混合诱捕的高、低密度和控制处理中虽然可看出果实的为害程度上有明显的差异,但是这些差异并非是使用性外激素诱捕器混合诱捕的结果. 1976—1979年Madsen和Carty等数人已报道过用性外激素诱捕苹果蠹蛾的控制研究,在这个研究中使用诱捕器密度为5—44个/公顷,结果证明混合诱捕作为控制种群的方法尚欠完善。经研究表明,在小的果园(孤立的)苹
The research was carried out in non-isolated, insecticide-prohibited commercial orchards. The purpose is to control Cydia pomonetla (L)] Grapholithamolesta (Busck); GPrunivora (Walsh); Argyrotaeina velut-lnana (Walker) Choristoneura rosaceana (Harris)] and Pandemis Limitata (Robinson)]. The traps of these six pests were traced using the sex pheromone trap, At both trapping densities, the fruit is harmed by these six pests and the damage of leaf roller moths exceeds the level that commercial fruit production can tolerate. While looking at the high, low density and control of hybrid trapping, However, these differences are not the result of mixed trapping using a pheromone trap. Several people, Madsen and Carty et al., Reported the control of codling moth by sexual pheromones from 1976 to 1979 The study, which used a trap density of 5-44 pcs / ha in this study, showed that hybrid trapping was poorly controlled as a method of controlling the population. Studies have shown that in small orchards (isolated)
