云南香料烟害虫种类及发生规律研究

STUDY ON THE SPECIES COMPOSITION AND OCCURRENCE OF PESTS IN ONENTAL TABACCO FIELDS

通过6 a系统调查,在云南省香料烟主产区烟田内共发现7目31科88种昆虫和野蛞蝓、灰巴蜗牛2种软体动物危害云南冬春香料烟。其中重要害虫是烟蚜(Myzus persicaeSu lzer)、棉铃虫(Heliothis arm igeraHübner)、烟草夜蛾(Heliothis assultaGuenèe)、烟草盲蝽[Cyrtopeltis tenuis(Reuter)]、野蛞蝓(Agriolimax agresfisL innaeus)、小地老虎(Agrotis ypsilonRottemberg)、东方蛄蝼(G.orientalisBurm e ister)、小长蝽[Nysius ericae(Sch illing)]等7种。烟蚜、野蛞蝓、小地老虎均为香料烟和烤烟上的重要害虫,在发生危害时期上较一致。棉铃虫、烟草夜蛾在香料烟上危害损失较大,而在烤烟上危害较轻。东方蝼蛄和小长蝽是香料烟上的主要害虫,在烤烟上发生较少,烟草盲蝽和金龟子在香料烟上发生较少,却又是烤烟的主要害虫。

In a six-year investigation carried out in tobacco fields in Yunnan, a total of 88 insect species belonging to 31 families, 7 ordens , and 2 kinds of mollusc were found in the oriental tobacco fields. The pest species which were widespread and caused great damage to the tobacco crops are Myzu persicae Sulzer, Heliothis armigera Hubner. H. assulta Guenee, Cyrtopeltis tenuis （ Reuter） , Agriolimax agresfis Linnaeus, Agrotis ypsilon Rottemberg, G. orientalis Burmeister and Nysius ericae （Schilling）, M. persicae, A. agresfi and A. ypsilon were dominant insect pests in both oriental and cured tobacco fields and they occurred on the tobacco plants almost simultaneously. H. armigera and H. assulta attacked mainly the oriental tobacco plants while G. orientalis and N. erieae fed mainly on cured-tobacco crops.
