采用定点监测、分级调查法对云南河口1.2万hm^2香蕉受褐足角胸叶甲(Basilepta fulvipesMotschulsky)的危害情况进行了研究。结果表明:褐足角胸叶甲发生、危害每年有3次以上的高峰期分别为4~5、7~8月和10月、12月至翌年3月为发生、危害的最低期;东部褐足角胸叶甲发生、危害最重,其次是西部及中南部;海拔高度和气候与褐足角胸叶甲的发生危害关系密切,海拔越高,危害率、危害指数越低,雨热同季、高温高湿比较有利于种群繁殖与发生危害。防治试验初步结果表明,参试的3种杀虫剂均有较好的防治效果,其中45%的马拉硫磷(跳丙)乳油1 000倍较好,在抽蕾初期防治可取得较好的防治效果,后期则效果降低或无效。
採用定點鑑測、分級調查法對雲南河口1.2萬hm^2香蕉受褐足角胸葉甲(Basilepta fulvipesMotschulsky)的危害情況進行瞭研究。結果錶明:褐足角胸葉甲髮生、危害每年有3次以上的高峰期分彆為4~5、7~8月和10月、12月至翌年3月為髮生、危害的最低期;東部褐足角胸葉甲髮生、危害最重,其次是西部及中南部;海拔高度和氣候與褐足角胸葉甲的髮生危害關繫密切,海拔越高,危害率、危害指數越低,雨熱同季、高溫高濕比較有利于種群繁殖與髮生危害。防治試驗初步結果錶明,參試的3種殺蟲劑均有較好的防治效果,其中45%的馬拉硫燐(跳丙)乳油1 000倍較好,在抽蕾初期防治可取得較好的防治效果,後期則效果降低或無效。

Occurrence and damage banana Basilepta fulvipes were studied by the methods of fixed monitoring and classification investigate in twelve thousands banana of Hekou.the Results show that the banana was damaged by Basilepta fulvipes year-round but damage peak more than three times each year.That respectively is April to May,July to August and October.Banana is least affected by the Basilepta fulvipes in December to march the next year.From the occurrence and damage extent all area,the banana of eastern is most serious affected by Basilepta fulvipes,followed by western and center south is more lighter than others places.Occurrence and damage banana Basilepta fulvipes are associate with the elevation's height and climate factors.The higher elevation,its damage index and damage rate is the lower.In other words,occurrence and damage banana Basilepta fulvipes associate with high temperature and high humidity environment.Control experimental results show that the experimental three insecticides are effective for controlling banana Basilepta fulvipes,45% of mlathion EC of 1000 times is the best.Among the three Insecticides,insecticides may provide a good control effects for Basilepta fulvipes in of banana female flower bloom,otherwise,the control effect may be reduced or control failure.
