摘要
云南地理与气候环境特殊,高温干旱地区以红蜘蛛和桑蓟马危害严重,世代重叠,为害时间长,连续干旱少雨便有爆发成灾的可能;同一地区,一年中随着气候变化,降雨分布也将影响到该地区虫害的发生格局。由于云南有"雨便成冬"的特点,在桑树生长期如雨量充沛,普发性害虫红蜘蛛、桑蓟马为害受抑制,反之虫害上升。因此。
Yunnan has a special geographical and climatic condition, so the pests in the arid area with high temperature are mainly red spider and Pseudodendrothrips mori which damaged the plants there for a very long time, and the successive droughts have made the pests attack possible; in the same area, with the annual climate change, the precipitation will also affect the outbreak of the pests attack in this area. Because of the special weather condition in Yunnan that it will become very cold after it rained, it will restrict the outbreak of the common pests as red spider and Pseudodendrothrips mori if it rains a lot, and vise versa. Therefore, the climate change will curb the pests attack.
