中文摘要：
为评价有机茶和无公害茶的茶园管理及多种茶园生境对茶尺蠖及其主要天敌密度的影响，利用栽培和生境调控技术抑制茶尺蠖、扶植天敌，于2002年7月至2003年7月选皖南有机、无公害和普通茶园各1个，7～10天1次，分别查10样方的茶尺蠖、2种绒茧蜂和6种蜘蛛密度，每样方为1m^2茶丛，依次查得茶尺蠖总数为227、8733和4769头，绒茧蜂总数为67、465和281头，蜘蛛总数为1669、1150和1077头。2004年10月至2006年9月选绍兴有机、有机转换、无公害和普通茶园各1个，每月查10样方，平均每月茶尺蠖分别为0．9、1．4、1．4和1．9头，绒茧蜂为10．1、12．3、11．5和10．4头，蜘蛛为9．3、9．5、9．4和9．9头。2005—2006年5天1次查得西湖龙井茶叶原产地10个茶园生境之间，茶尺蠖、绒茧蜂或蜘蛛密度差异均达显著水平（P〈0．05）。绍兴4个、龙井原产地10个茶园中绒茧蜂皆紧密跟随茶尺蠖。
英文摘要：
In order to evaluate the impact of the farming methods and the various habitats of tea gardens on population density of tea geometrids Ectropis oblique and its main natural enemies, and to make use of cultivating techniques and habitats regulation to restrict tea geometrids and to assist its natural enemies, a survey of tea geometrids and its main enemies, two species Apanteles and six species of spiders, from ten plots, one plot being 1 m2 tea clump, respectively from an organic tea garden （O）, a non-pollution tea garden （N） and a common tea garden （C） was conducted in the southern Anhui Province from July of 2002 to July of 2003, at intervals of 7 - 10 days. The results showed that the total population of tea geom- etrids was 227 （0）, 8733 （N） and 4769 head （C）. The total population of braconid wasps was 67, 465 and 281 head （C）. And the total population of spiders was 1669, 1150 and 1077 head （C）. Another survey of tea geometrids, the two species of braconid wasps and the six species of spiders, from ten plots, respectively from an organic tea garden （ O）, an organic conversion tea garden （OC）, a non-pollution tea garden （N） and a common tea garden （C） was completed in Shaoxing City, Zhejiang Province from October of 2004 to September of 2006, at intervals of one month. The results showed that the average population per month ： tea geometrids＇ was 0.9 （ O）, I. 4 （ OC）, I. 4 （N） and I. 9 head （ C）, braconid wasps＇was I0. I （O）, 12.3 （OC）, 11.5 （N） and 10.4 head （C）, and spiders＇was 9.3 （O）, 9.5 （OC）, 9.4 （N） and 9.9 head （C）. The difference in population of tea geometrids, braconid wasps or spiders from ten tea garden habitats locating in the famous ＂Xihulongjing Tea＂ original production area （ Hangzhou, Zhejiang）, which were investigated from the year of 2005 to 2006 at intervals of 5 days, was distinct with the significance level of P 〈 0.05. In the four tea gardens in Shaoxing or in ten tea garde
