摘要
研究了美洲斑潜蝇种群数量与气象要素之间的关系 ,统计分析表明 :美洲斑潜蝇种群数量与气温、降水量、相对湿度均呈指数相关 ,并达到极显著水平 ,而与日照时数无关。逐步回归分析表明 :美洲斑潜蝇种群数量的自然对数与气温关系最密切 ,偏相关系数为 - 0 5 92 ;其次是相对湿度 ,偏相关系数为 - 0 2 77 。
Relationship between the number of Liriomyza staivae and the Meteorological factors were studied in this paper.The results of statistics showed that the number of Liriomyza staivae was found to be highly significant correlated with temperature,precipiation and relative humidity,but it was not correlated with sunshine duration.Stepwise regression analysis indicated that the Natural Logarithmic of the number of Liriomyza staivae was negatively correlated with temperature, r=-0.592 ** , the next was relative humidity, r=-0.277 ** .
