三亚市桉树枝瘿姬小蜂监测模型研究

通过对海南省三亚市桉树枝瘿姬小蜂数量调查,并结合6个关键气候因子,运用SAS9.0进行回归分析,得到了桉树枝瘿姬小蜂监测模型：y=0.549 3＋0.000 6x1＋0.269 3x3＋0.415 6x4-0.612 2x5-0.023 1x6。该模型表明桉树枝瘿姬小蜂数量与月降雨总量、月平均最高温度、月平均最低气温、月平均温度和月平均相对湿度有极显著相关性,而与月日照时数无显著相关性。其中月降雨总量是影响桉树枝瘿姬小蜂数量的主要气候因子,其次为月平均温度、月最低平均温度与月最高平均温度。

Monitoring Model for Leptocybe invasa Fisher et La Salle in Sanya

The quantity of Leptocybe invasa Fisher et La Salle in Sanya was investigated.A monitoring model was established for the quantity of Leptocybe invasa Fisher et La Salle based on six key climatic factors and regression analysis with SAS9.0 program.It was y=0.549 3＋0.000 6x1＋0.269 3x3＋0.415 6x4-0.612 2x5-0.023 1x6.The model showed that there was a very significant correlation between quantity of Leptocybe invasa Fisher et La Salle and five climatic factors such as total rainfall per month,monthly average maximum temperature,monthly average lowest temperature,monthly average temperature,and monthly average relative humidity.The quantity of Leptocybe invasa Fisher et La Salle was not significantly associated with total sunlight time per month.Total rainfall per month was the main climate factor which influenced the quantity of Leptocybe invasa Fisher et La Salle.
