Abstract:

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+10.6752x2-3.4696x3-4.9768x4-0.1259x5-0.3897x7, R=0.7851××. Whether it can be used as a monitoring tool for field populations still need to be further studied.
