The relationship between the biological characteristics of Citrus fruit flies and temperature

YU Li-ping,XU Nan-chang  
In order to control the spread and hazard of small fruit flies effectively,the outdoor breeding test was engaged from 2009 to 2010.The results show that there is a high correlation relationship between the biological characteristics of small fruit fly and the temperature.The temperature influences the pre-spawning length and the time of the spawning significantly.While the average temperature is in the range of 20.3-29.9℃,the period from the adults'first mating to the last mating prolonged with the increasing of temperature.In different temperature period the spawning time and number of ovum for each of the adults are different,and the larval duration shortens with the increasing of temperature.The adults are not sensitive to low temperature and can't survive through the winter,and its emergence rate decreases while the temperature increases.Above will provide scientific basis for small fruit fly prevention and control technology research and forecasting of citrus,and consequently ensure the safety of citrus production and the rural stability in Quzhou.
