Abstract

Calotropis gigantea is a drought-resistant and salt-tolerant plant native to Sri Lanka with medicinal and ecological values. Although C. gigantea is widely distributed in Sri Lanka, information on insects associated with the plant is lacking. The objective of the study is to identify insect fauna of C. gigantea. Surveys were conducted in all provinces of Sri Lanka from December 2014 to June 2015 and insects of C. gigantea and their biotic associations were documented. Twelve morphospecies of phytophagous pests, six species of pollinators, and fourteen species of occasional visitors were documented. Their incidence/ abundance varied widely, spatially, and temporally. Dacus persicus and Paramecops farinosus were highly damaging, monophagous pests while Sphaeroderma sp. was widespread. Xylocopa spp. were the most abundant pollinators. Occasional visitors have belonged to six orders and their diversity was very high. The study provides information on the insect fauna associated with C.gigantea as the initial record from Sri Lanka.
