摘　　要：为了科学施药,合理保护和利用天敌进行油桃园害虫的综合防治,用t检验法比较"518"油桃季节间和年度间害虫及其天敌的种群差异,结果表明两年春-夏季之间小绿叶蝉、桃蚜、山楂叶螨和李肖叶甲4种害虫的t值分别为0.8049、1.1449、0.0700和0.9895,t值均小于t0.05(2.26),差异均不显著;异色瓢虫、龟纹瓢虫、粽管巢蛛、八斑球腹蛛、三突花蟹蛛、草间小黑蛛、中华草蛉和黑带食蚜蝇8种天敌的t值分别为1.7014、0.9098、1.4304、0.6239、0.1545、0.0544、1.5579和0.8249,t值均小于t0.05(2.26),差异均不显著。2009年春-夏与2009年秋季之间,桃蚜的t值为38.8150,粽管巢蛛的t值为9.1706,t>t0.01(3.355),差异均极显著,异色瓢虫、三突花蟹蛛、黑带食蚜蝇的t值分别为2.3332,3.1497和2.4712,t>t0.05(2.306),差异显著;2010年春-夏与2009年秋季之间,粽管巢蛛t值为7.0763,t>t0.01(3.355),差异极显著,其余差异均不显著。采用灰色系统分析方法、生态位分析方法,对2009年及2010年春-夏季油桃园桃蚜、小绿叶蝉、山楂叶螨和李肖叶甲与其捕食性天敌在数量、时间和空间格局等方面关系进行分析,对每一种天敌对应的关联度、生态位重叠指数和相似性比例等参数标准化后相加,按照参数标准化值之和大小排序得出,2009年春-夏季小绿叶蝉前3位的主要天敌是异色瓢虫、八斑球腹蛛和龟纹瓢虫;桃蚜的主要天敌是中华草蛉、粽管巢蛛和异色瓢虫;山楂叶螨的主要天敌是草间小黑蛛、三突花蟹蛛和龟纹瓢虫;李肖叶甲的主要天敌是草间小黑蛛、八斑球腹蛛和龟纹瓢虫。2010年春-夏季小绿叶蝉的主要天敌是龟纹瓢虫、八斑球腹蛛和草间小黑蛛;桃蚜的主要天敌是中华草蛉、黑带食蚜蝇和粽管巢蛛;山楂叶螨的主要天敌是八斑球腹蛛、草间小黑蛛和龟纹瓢虫;李肖叶甲的主要天敌是草间小黑蛛、八斑球腹蛛和异色瓢虫。2009年秋季小绿叶蝉To conserve and utilize natural enemies for comprehensive control of insect pests in peach orchards,the seasonal and annual variations of population quantities of four insect pests with their natural enemies in ＂518＂ nectarine orchard were systematical investigated.The results of a paired t-testing showed that the t values of four main pest numbers,i.e.Empoasca flavescens,Myzus persicae,Tetranychus viennensis and Cleoporus Variabilis,were,respectively,0.8049、1.1449、0.0700、0.9895,whilst the t values of eight natural enemy numbers,i.e.Harmonia axyridis,Propylaea japonica,Clubiona japonicola,Theridion octomaculatum,Misumenops tricuspidatus,Erigonidium graminicola,Chrysopa Sinica,Epistrophe balteata,were,respectively,1.7014、0.9098、1.4304、0.0639、0.1545、0.0544、1.5579、0.8249 between the two spring-summer seasons of 2009 and 2010,which all are significantly lower than 2.26（t0.05 value）,indicating that no significant differences existed in the numbers of four insect pests and their natural enemies between the two spring-summer seasons in ＂518＂ nectarine orchard.The further analysis indicated that the t values of Myzus persicae and Clubiona japonicola were,respectively,38.8150 and 9.1706 with t〉t0.01（3.355）,and the t values of Harmonia axyridis,Misumenops tricuspidatus,Epistrophe balteata were,respectively,2.3332,3.1497 and 2.4712 with tt0.05（2.306）,indicating that there were significant differences in their numbers between the spring-summer season and the autumn season of 2009 in ＂518＂ nectarine orchard.Moreover,there was also highly significant difference in the numbers of Clubiona japonicola（t=7.0763,P〈0.01） between 2010 spring-summer season and 2009 autumn season in ＂518＂ nectarine orchard,whereas no significant differences existed in the others.The quantity,time and space framework of Myzus persicae,Empoasca flavescens,Tetranychus viennens,Cleoporus variabilis and their predatory natural enemies in 2009 spring-summer season and autumn season,as well as 2010 sprin
