摘　　要：对实验室内盆栽晚香玉(PolianthestuberosaL.)叶部害虫进行调查和防治,并对温室内地栽晚香玉花序害虫发生情况进行调查。确定害虫的种类有:为害叶部的害虫为二斑叶螨(TeytanychusurticaeKotch)及桃蚜(MyzuspersicaeSulzer),为害花序部的害虫为花蓟马(Fran kliniellaintonsaTrybom)、黄胸蓟马(ThripshawaiiensisMorgan)和棉铃虫(HeliothisarmigeraHubner)。调查结果表明:为害晚香玉的害虫种类较多,二斑叶螨及蓟马为害较大,二斑叶螨发生的虫口密度为76.43～86.53头 盆。蓟马发生的虫花率为78.45%,花斑率为73.68%,严重影响了晚香玉正常的生长及鲜切花生产的质量和数量。防治试验应用了清源保和乐斯苯两种药剂。结果表明:两种药剂的防治效果无明显差异。清源保600倍液防治效果达96.32%～100.00%,乐斯苯1000倍液防治效果达95.51%。清源保600倍液防治二斑叶螨既经济,又有效,是一种有效的环保型药剂。The foliage pests of tuberose potted in laboratory and cultivated in greenhouse were investigated.The variety of pests was identified as Tetranychus urticae and Nyzus persicae that endangered the leaves.Frankiniella intonsa Trybom,Thrips hawarrensrs Morgan and Heliothis armigera Hubner harm large quantity of cutting flowers among the pests investigated. The number of tetranychus urticae existed in a pot was 76.43 to 86.53. The percentage of thrips observed on flowers was 78.45% and the speck hurt by thrips was 73.68%.The pesticides Kingbo and Losben were used to eliminate the pests. There were no significant difference between the effect of Kinbo and Losben. The results of elimination show that the death rate of pests was 96.32%～100.00% after Kinbo was sprayed and 95.51% when Losben had been used. The pesticide Kinbo diluted to 600 times was not only effective but also economic to eliminate the pests and had hardly any contaminations to environment.
