山东省气象条件对一代玉米螟的影响

利用1976-2005年一代玉米螟盛期卵量、玉米成灾面积与气象因子进行相关性分析，结果表明一代玉米螟的发生发展主要与温度、湿度气象因子有关。其中普查盛期一代玉米螟卵量与5月下旬平均气温呈显著负相关； 玉米受灾面积与5月上旬-中旬平均最低气温及6月上旬平均最高气温呈显著正相关。

Influence of Meteorology on the First Generation of Corn Borer in Shandong Province

Based on the amount of eggs of the first generation of corn borer, the damage area of corn and the related meteorological conditions in Shandong province from 1976 to 2005, two factors affecting the occurrence of the first generation of corn borer were analyzed and the liner related equation was established. The results showed the amount of eggs of the first generation of corn borer was negative correlation with the average temperature of the end of May, and the damage area of corn was correlation with the lowest air temnerature nf the lst ten-days of May to Mid-May, and highest air temperature of the lst Ten-days of June.
