1999年 1 2月～ 2 0 0 0年 1月在皖南 2个林场马尾松林中各设立 2块样地 ,每月调查 1次。查得马尾松树上 1 2目、35科共 62种昆虫和蜘蛛 ,益害物种数之比为 1 .2 6,益害个体数之比为 0 .62。天敌种数稍多于害虫。优势目是双翅目、同翅目、鞘翅目、鳞翅目、膜翅目和蜘蛛目。植食性、捕食性、寄生性昆虫和蜘蛛的物种数分别为 30、8、1 0和 2 0。冬季少数生物还在活动 ,月间的总物种数和总个体数有所波动。常年放菌治虫的戴公山林场益害比和多样性指数稍大于滥用农药的麻姑山林场。马尾松树树上和树皮下是昆虫和蜘蛛重要的越冬场所。
From January 1999 to February 2000, two plots were set up in each of the two Pinus massoniana forests in southern Anhui, and once a month. A total of 62 species of insects and spiders belonging to 12 orders and 35 families in Masson pine were investigated. The ratio of beneficial species was 1.26, and the ratio of beneficial individuals was 0.62. Natural enemies slightly more than the number of pests. The dominant species are Diptera, Homoptera, Coleoptera, Lepidoptera, Hymenoptera and Araneae. Species of herbivorous, predatory, parasitic insects and spiders were 30, 8, 10 and 20, respectively. Winter few living things are still active, the total number of species during the month and the total number of individuals fluctuate. Perennial fungous Dai Gongshan forest damage ratio and diversity index slightly larger than the abuse of pesticides Ma Gu Shan farm. Under the trees and under the bark of the pine trees are important wintering places for insects and spiders.
