Ants associated with the mealybugs of coffee.

Abstract

The 9 species of ants reported in association with mealybugs [Pseudococcidae] on coffee from the Coorg district of Karnataka and the Wayanad district of Kerala, India, are Crematogaster sp., Tapinoma melanocephalum, Anaplolepis longipes, Oecophylla smaragdina, Myrmicaria brunnea, Technomyrmex albipes, Paratrechina longicornis, Acropyga sp. and Plagiolepis sp. The nature of their associations with mealybugs and each other is discussed, and it is suggested that the presence of Acropyga (which chases away Plagiolepis) may be a strong reason for the lower incidence of mealybugs in Coorg, and its absence in Wayanad may be responsible for the heavy incidence of mealybugs there.
