| 摘 要： | 为探明在冬种豇豆的整个生育期内,为害豇豆的蓟马种类及各种蓟马的种群消长情况,于2014—2016年在海南三亚开展了冬种豇豆的蓟马种类和数量的调查。结果表明:为害豇豆的蓟马有4种,即豆大蓟马、花蓟马、棕榈蓟马和黄胸蓟马;其中,豆大蓟马与棕榈蓟马在豇豆的整个生育期内均可为害,花蓟马与黄胸蓟马仅在花期发生。豆大蓟马为豇豆蓟马的优势种,其发生高峰期在豇豆的盛花期;其次是花蓟马,其数量在豇豆生长后期逐渐增加;棕榈蓟马的数量在豇豆花期虽有所增加,但始终维持在较低水平;黄胸蓟马仅偶尔出现,且数量极少。为了解新型杀虫剂对豇豆蓟马的防效,采用喷雾法,开展了豇豆蓟马的田间药效试验。试验结果表明:在参试的5种新型药剂中,乙基多杀菌素和苦参碱对豇豆蓟马具有较好的防效,药后3天防效分别为79.14%和62.14%,高于对照药剂啶虫脒的防效。药后7天,所有参试药剂对豇豆蓟马的防效均不理想,除了乙基多杀菌素,其余药剂防效均小于50%。在参试的药剂中,乙基多杀菌素、苦参碱对豇豆蓟马具有较好的防效,可以与啶虫脒轮换使用,用于豇豆蓟马的田间防治。

| Abstract: | To investigate the thrips species on the cowpea Vigna unguiculata and to explore the population trends of various kinds of thrips throughout the winter growing season of cowpea, the thrips species and number were surveyed weekly from 2014 to 2016 in Sanya, Hainan Province. The investigation indicated that there were four kinds of thrips: Megalurothrips usitatus (Bagnall), Frankliniella intonsa (Trybom), Thrips palmi Karny and Thrips hawaiiensis Morgan attacked cowpea. M. usitatus and T. palmi occured throughout the winter growing season of cowpea crop, when F. intonsa and T. hawaiiensis occurred only in flowering phase. M. usitatus was the dominant thrips species, and its occurrence peak appeared in the full bloom stage. F. intonsa was the second important thrips, and its quantity increased gradually in the later growth stage of cowpea. Though T. palmi increased in the bloom stage, it was still at a low level. T. hawaiiensis occurred occasionally, and was few in number. Field trials were carried out to evaluate the control efficiencies of new insecticides against thrips during the cowpea full bloom stage. The result indicated that spinetoram and matrine showed better control efficiency than acetamiprid (control) on thrips, and the control efficiencies of spinetoram and matrine were 79.14% and 62.14% respectively at 3 days after spraying (d.a.s.). But the control efficiencies of all treatments excepted spinetoram were less than 50% at 7 d.a.s.. These findings suggest that spinetoram and matrine were considered as optimal pesticides among the five new insecticides for managing thrips, which could be used in alternation with acetamiprid to control thrips in cowpea. |
