Effects of Main Meteorological Factors on the Population Fluctuation of Loxostege sticticalis:Lepidoptera: Pyralidae)in Habahe County

【Objective】 To explore the relation between the main meteorological factors to the population fluctuation of Loxostege sticticalis.【Method】During the period of 2015 and 2016 the systematic analysis of the effects of the main meteorological factors on the population dynamics of L. sticticalis in the Habahe County was carried out.【Result】The population of L. sticticalis reached the peak between mid-June and mid-July. The regression analysis indicated that the average temperature, maximum and minimum temperature, relative air humidity, precipitation and sunshine hours were the main meteorological factors affecting the population fluctuation of L. sticticalis. The increase of maximum temperature and minimum temperature limited the increase of L. sticticalis.【Conclusion】The average temperature and relative humidity in Habahe County during June and August are conducive to the growth and development of L. sticticalis, and therefore L. sticticalis is the most rampant during this time.
