    in different time and the nectar compositions. The results showed that O. corniculata could extend longevity and improve fecundity of T. chilonis significantly. T. repens could extend longevity and improve fecundity of T. chilonis, but there was no significant difference between T. repens-fed treatment and water-fed treatment. The test of nectar content showed that O. corniculata flowers had the highest nectar content from 14:00 to 16:00. T. repens flowers were basically in bloom for 24 h, but O. corniculata flowers were only open in the daytime. After 20:00, O. corniculata flowers were all closed. O. corniculata flowers contained a mass of nectar content and could significantly improve parasitic wasp biological fitness. Furthermore, O. corniculata flowers were only blooming during the daytime, which indicated that O. corniculata does not benefit moths. In conclusion, O. corniculata could be utilized as a potential nectar resource plant in rice-based agroecosystem.
