多年来,林区联手防治爆发性害虫——竹蝗,已收到了显著效果。即相邻地区的园林与林业部门共同制订防治方案,统一行动,把竹蝗的危害损失控制在最低程度。1.竹蝗的发生与环境条件密切相关一是气候条件。气候因素对竹蝗的生长发育和活动取食关系密切,一般高温干燥年份,即为蝗虫卵孵化最适宜的年份;早春回暖早,孵化亦提早,春寒多雨则推迟孵化。当气温在23~26℃,地温24~27℃时最适宜蝗卵孵化;在4—6月份降雨量在200毫米以
Over the years, the joint efforts of the forest areas to prevent and control the outbreak of pests - Zhu Zhu, have received significant results. In other words, the gardens and forestry departments in the adjacent areas jointly formulated the prevention and control plans and unified the actions to minimize the harm and loss of the bamboo locusts. 1. Bamboo locust occurrence and environmental conditions are closely related to First, the climatic conditions. Climatic factors on the growth and development of bamboo locust feeding closely related to the general high temperature drying years, that is, the most appropriate year of locust egg hatching; early spring back to early hatch also earlier, the spring cold rain is delayed hatch. When the temperature is 23 ~ 26 ℃, the ground temperature 24 ~ 27 ℃ when the most suitable locust egg hatch; in April-June rainfall at 200 mm
