摘　　要：根据1984-2005年草地螟发生发展与同期气象资料,分析草地螟发生发展的气象条件。结果表明:草地螟都在进入5月以后始见,且主要集中在5月,春季相邻两旬平均最低气温在8℃以上时,草地螟就会始见;草地螟始见后温度仍对草地螟的发展起着重要作用,环境平均温度在23℃以下时,温度越高,对害虫发展越有利,超过23℃后温度越高对草地螟发展的抑制作用越大。从7月中旬开始降水对草地螟始盛起抑制作用,降水多,草地螟始盛明显延迟。蒸发量对向日葵草地螟发展一直有抑制作用。同时,利用气象资料和对应的草地螟发生发展观测资料建立了预测模式。Making use of a correlation calculation and contrast analysis according to 1984-2005 loxoszege stictialis occurrence development and same period weather data,the weather condition when loxoszege stictialis occurrence were obtained.The results showed that: loxoszege stictialis was found after April,and mainly in May,continuous two ten days in spring when average lowest air temperature was higher than 8℃.After loxoszege stictialis appear,temperature also had some affect on the development of the loxoszege stictialis.When daily mean temperature was lower than 23℃,the higher temperature would benefit the development of pests,when daily mean temperature was higher than 23℃,the higher temperature would refrain the development of loxoszege stictialis.Since mid-July,precipitation would limit the development of loxoszege stictialis,more precipitation would greatly delay the boom of loxoszege stictialis.Evaporation showed some refrains to the development of the sunflower loxoszege stictialis.The forecasting model was build up by using the weather data and observed data of the occurrence and development on the loxoszege stictialis.
