| 摘 要： | 本研究系统调查了红栀子Gardenia iasmitmnides Ellis园中主要害虫与天敌种类及其田间发生动态，发现红栀子主要害虫有咖啡透翅天蛾Cephorwdes hylas L.日本龟蜡蚧Ceroplastes japoruicus Green，茶长卷叶蛾Homona magnanima Diakonoff,小灰蝶Deuabrix eryx L．；主要天敌有螟虫长距茧蜂Macrocentrus linearisNees，草蛉Chrysopa corneaSephens,赤眼蜂Trichogramma spp。田间种群动态调查结果表明：4、5月，几种害虫的发生量呈上升趋势，6、7月咖啡透翅天蛾的发生先上升后下降；而日本龟蜡蚧的发生则稳步上升；小灰蝶和茶长卷叶蛾先下降然后上升达到一个相对稳定水平。8月，除小灰蝶的发生是呈上升的趋势外．另外三种主要害虫的发生呈下降的趋势。草蛉在田间稳定增长，螟虫长距茧蜂的发生有波动，但总体上呈上升趋势。赤眼蜂在7月前有一定波动，7月后稳定上升。

| Abstract: | Species of main pests and their natural enemies in Gardenia jasminonides Ellis field were investigated and their field dynamic occurrence was examined in this research. Major pests were Cephonodes hylas L., Ceroplastes japonicus Green, Homona magnanima Diakonoff, and Deudorix eryxL., Macrocentrus linearis Nees, Chrysopa carnea Stephens and Trichogramma spp.were the main natural enemies. In Aprial and May the field occurance of the main pest increased gradually. In June and July, the population of C.hylas raised first and then descent; and C.japonicus had a stable rising trend; the population of H.magnanima and D.eryx descent first and then rising to a relatively stable level. In August only the numbers of D.eryx raised. In field C.carnea raised gradually all the time. The occurance of M.linearis fiuctuatcd slightly. The population of Trichogramma spp. fluctuated before July but following rised stable. |
