黄色粘胶板诱杀柑桔木虱成虫田间试验初报

黄板对柑桔木虱诱杀率最高的月份是7月，诱杀率最高90.52%、最低6.13%,平均55.82％；8月诱杀率最高38.66%、最低3.90%,平均19.75％；11月诱杀率最高9.52％、最低0、平均4.36％。诱杀率与日平均气温、日最高气温、日最低气温呈极显著正相关，温度越高，诱杀率越高；与挂黄板后的天数呈显著负相关。黄板对柑桔木虱的诱杀率比较低，不能用来作为防治工具。以2天前的日均日照时数x1、日均气温x2、日均最高气温x3、日均最低气温x4、日均降雨量x5、日均降雨天数x6、悬挂黄板天数x7为自变量，以诱杀率反正弦平方根代换值为因变量，进行逐步回归分析，建立的数学模型如下：诱杀率y=-20.5213+10.6752x2-3.4696x3-4.9768x4-0.1259x5-0.3897x7，R=0.7851**，是否可以作为一种监测田间种群数量的工具，还有待于进一步研究。

Field Trial Preliminary of Trapping Adult Citrus Psylla with Yellow Trap

The highest trapping rate month of citrus psylla with Yellow Trap is July. The highest rate is 90.52%, the lowest rate is 6.13%,the average rate is 55.82%. In August, the highest rate is 38.66%, the lowest rate 3.90%, the average rate 19.75%. In November, the highest rate 9.52%, the lowest rate 0, the average rate is 4.36%. Trapping rate has significant positive correlation with daily mean temperature, daily maximum temperature and daily minimum temperature. The higher the temperature the higher the trapping rate. However, the trapping rate has negative correlation with the days after hanging yellow glue board. The trapping rate of citrus psylla with yellow glue board is lower, and can not be used as control tool. Using average daily sunshine hours X1, average daily temperatures x2, average daily maximum temperature x3, average daily minimum temperature x4, average daily rainfall x5, daily rainfall days x6, hoisted yellow plate number of days x7 as independent variables, and the trapping rate of arcsine square root of the substitution value dependent variable. Employing stepwise regression analysis to establish mathematical model： Trapping rate y =-20.5213 ＋ 10.6752 x2-3.4696 x3-4.9768 x4-0.1259 x5-0.3897 X7, R=0.7851＊＊. Whether it can be used as a monitoring tool for field populations still need to be further studied.
