虫情测报仪是一种新型测报工具,广泛应用于农、林业虫害监测防控工作中。2017年3—8月,在云南省玉溪市红塔山自然保护区灵照山林区应用虫情测报仪开展森林害虫灯光诱测,结果表明,虫情测报仪诱集害虫种类多,虫量大,虫峰日期明显,对鳞翅目和鞘翅目森林害虫具有较好的监测和防治作用,且使用安全方便,对天敌相对安全,防治效果显著。根据诱测结果,对金龟子类和天牛类成虫以及天蛾科、蚕蛾科绿尾大蚕蛾、枯叶蛾、尺蛾类、灯蛾类等林业害虫的发生动态及峰值进行分析,结果表明,所监测到的森林害虫种群数量不大,对该区域森林不会造成威胁。 相似文献

With the expected rising temperatures, outbreaks of insect pests may be more frequent, which can have large consequences on forest ecosystems and may therefore negatively affect the forestry sector. In order to be better able to predict where, but not if, outbreaks may occur in future we investigated the potential future (2070) geographical distribution of 30 prospective insect pest species (Coleoptera and Lepidoptera) by applying species distribution modelling. We also assessed the geographical extent to which the boreal forest in Sweden may be affected. We found that numerous species may experience large increases in their potential distribution in future, which may result in outbreaks in “new” areas. It is therefore likely that more trees will be infested by pests in future, which may have large implications for the Swedish forestry sector. 相似文献

Polyculture in crop agroecosystems has been examined in numerous studies with the aim of reducing pest populations by increasing
diversity among insect populations over those found in traditional monoculture. Resource concentration and enemies hypotheses
predict decreased pest populations in more diverse plant communities. Although results have been mixed, insect diversity has
been generally increased in polyculture over traditional monoculture. Maintaining natural insect diversity in managed forests
to limit possible pest outbreaks has been the goal in forestry systems. Increased arthropod diversity with increased tree
diversity has been observed, though fewer studies have been conducted in forestry compared to agriculture. Agroforestry holds
promise for increasing insect diversity and reducing pest problems because the combination of trees and crops provides greater
niche diversity and complexity in both time and space than does polyculture of annual crops.
