【摘要】 根据宁夏枸杞红瘿蚊在不同湿度沙土和壤土内的出土率试验结果,确定了不同土壤类型的枸杞红瘿蚊孵化出土的适宜土壤水分条件。根据枸杞红瘿蚊羽化出土后的危害率与气象条件的关系,建立了田间危害程度的气象关系模型和指标。结果表明,该模型对枸杞红瘿蚊羽化后的危害高峰期模拟、判断准确,但对夏末以后的预测检验存在一定误差。更多还原

【Abstract】 Based on the experiment results of feeding Jaapiella sp.with different soil moisture in the sand and clay soil,the suitable soil moisture indexes of Jaapiella sp.eclosion under different soil types were obtained.According to the relationship between Jaapiella sp.of eclosion hazard rate and its meteorological conditions,the models and meteorological indexes of field hazard degree were set up.The result showed that all the models and indexes were correct when hazard summit period simulating after the Jaapiella sp.eclosion,but not accuracy of prediction test at the end of summer.更多还原
