Influence of weather factors on flight of natural enemies that captured on the light traps. The Research was carried out in the 2013 at Sukamandi rice research station of Indonesian Center for Rice Research (ICRR). Natural enemies captured on the light traps of mercury lamp ML-160 watt and CFL-20 watt, while the weather data was collected from a meteorological cage within 200 m from the light trap. The results showed that the weather factors such as evaporation, wind velocity, light intensity, air temperature, relative humidity, rainfall and temperature of soil surface at 0 cm were insignificant effect to flight of O. nigrofasciata and P. fuscipes that captured on mercury lamp 160 watt and CFL-20 watt. The temperature of soil surface at 0 cm was significant positive influence to Coccinella sp. that captured on the mercury lamp 160 watt, while the Coccinella sp. that captured on the CFL bulbs 20 watt were significant negative influenced by rainfall and relative humidity. The facts explainthat flight of Coccinella sp. were determined by environmental resultant factors between weather, lamp light capacity, and luminous power.
