福建省三明市主要森林病虫害的发生格局
Occurring pattern of the main forest pests and diseases in Sanming of Fujian Province
摘要
Abstract
Based on collection and analysis of the data in the duration from 1993 to 2007, the species composition of main forest pests and diseases in Sanming of Fujian Province was clarified, and their temporal and host distribution patterns were also discussed. Results showed that there were 21 species of the main forest pests and 11 species of the main forest diseases in Sanming, and an increasing trend in pest and disease species number was observed, in which some dangerous forest pests or diseases including Cryphonectria parasitica, Cylindrocladium scoparium, Ceratosphaeria phyllostachydis and Hylobitelus xiaoi were found. In the yearly sequence, the total occurring acreage in forest pests and diseases increased slowly by a fluctuating mode from 1993 to 2003, but rapidly increased after 2004, and then displayed a severe occurring pattern till 2007. The following four aspects, including (1)shortening of time cycle and increase of intensity in outbreak of Dendrolimus punctatus and Pantana phyllostachysae, (2)resurgence of Ceracris spp., (3)some minors pest becoming major pests e. g. Monochamus alternatus and Loudonta dispar and (4)intermittent occurrence of some dangerous pests including B.xylophilus, H.xiaoi and C.scoparium, might be the essential causes. In Sanming, pine and moso bamboo were most severely damaged by the forest pests and diseases for their largest occurring acreage and more pest species. At last, five effective models in D.punctatus, P.phyllostachysa, Ceracris spp., bamboo mites and Lecanosticta acicola were constructed, respectively, in order to forecast their next outbreak year by the gray theory.关键词
