Contribution of Diurnal and Nocturnal Insects to the Pollination of Jatropha curcas (Euphorbiaceae) in Southwestern China

摘要: Jatropha curcas L. (Euphorbiaceae) is being increasingly planted worldwide, but questions remain regarding its pollination biology. This study examined the contribution of diurnal and nocturnal insects to monoecious J. curcas, through floral biology, ecology, foraging behavior potential pollinators. Nectar production both male female flowers peaked in morning, declined afternoon, rapidly bottomed during night all their anthesis days. The visitors are bees flies, moths. Flowers received significantly more visits by than insects. Through bagging or day exclusion, we compared fruit seed caused Both were successful However, exposed only produced less fruits those visitors. Thus, pollinators contribute at site.
