摘要
:1 998年 1～ 1 2月每月下旬 ,对皖南敬亭山茶场栗 -茶间作、梨 -茶间作、3行密植和单行条植茶园节肢动物群落的调查表明 :植食性昆虫种数分别占各类型茶园总物种数 51 .9%、53.6%、54.4 %和 56.6% ,个体数依次占各类茶园总个体数 92 .0 %、93.5%、93.6%和 95.0 % ;捕食性昆虫和捕食螨种数则分别占 1 1 .3%、1 0 .0 %、9.8%和 1 0 .9% ,个体数占 2 .0 %、1 .1 %、2 .0 %和 1 .5% ;寄生性昆虫种数占 9.2 %、9.1 %、9.3%和 9.3 % ,个体数占 1 .8%、1 .1 %、1 .8%和 1 .3 % ;蜘蛛种数占 2 4 .7%、2 0 .1 %、2 2 .4 %和 1 9.4 % ,个体数占 3.5%、3.4 %、2 .1 %和 1 .8%。 4类茶园中的优势类群都是鳞翅目、同翅目、膜翅目、双翅目和蜘蛛目。月平均丰富度 ( S)和多样性指数 ( H′)大小顺序 :栗 -茶间作 ( S=74 ,H′=1 .33)、梨 -茶间作 ( S=4 9,H′=1 .2 4 )、3行密植 ( S=31 ,H′=1 .0 3)和单行条植茶园 ( S=2 3,H′=0 .89)。主成分分析揭示了群落稳定性的大小 :栗 -茶间作 >梨 -茶间作 >3行密植 >单行条植茶园。
Surveys to arthropod communities in chestnut-tea intercrop, pear-tea intercrop, 3 row close planting and single row planting tea gardens were conducted.The results showed that: (1) Phytophagous pest species number to total species number in percentage was 51.9 % , 53.6 %, 54.4 % and 56.6 %, respectively in the above four cultivation styles,and the individual number to total individual number in percentage was 92.0 %, 93.5 %, 93.6 % and 95.0 %. (2) Predatory species number to total species number in percentage was 11.3 % , 10.0 % , 9.8 % and 10.9 % and the individual number was 2.0 % ,1.1 %, 2.0 % and 1.5 % . (3) Parasitic insect species number was 9.2 %, 9.1 % ,9.3 % and 9.3 % and individual number were in turn 1.8 %,1.1%,1.8 % and 1.3 %.(4) Spider species number was 24.7 %, 20.1 %, 22.4 % and 19.4 % and individual number was in turn 3.5 % , 3.4 %, 2.1 % and 1.8 %. Dominant groups within the four types of tea gardens were Lepidoptera, Homoptera, Hymenoptera, Diptera and Arancida. Average richness (S)and diversity indices(H′)per month took on the following order: chestnut-tea intercrop(S=74, H′=1.33) > pear\|tea intercrop(S=49, H′=1.24)>3 row close planting (S=31, H′=1.03)> single row planting tea gardens(S=23, H′=0.89). Principal component analysis indicated that community stability was in the order: chestnut\|tea intercrop >pear\|tea intercrop>3 row close planting > single row planting tea garden.
