DYNAMICS OF COLONIZATION AND GYNE PRODUCTION BY MONOMORIUM-PHARAONIS (L) (HYM, FORMICIDAE) IN BRAZIL

Abstract

The colonization characteristics of two neighboring populations of Monomorium pharaonis in human structures in Brazil were compared. No differences in the seasonality of colonizations into fixed trap nests between the two populations were found. However, one population had higher frequencies of colonizations with accompanying queens than the other. This resulted in the other population producing new queens at a higher frequency than the other. There was a clumping of colonization attempts at specific points, which shows that colonization may be predictable. These findings may be of importance in control programs for M. pharaonis in structures.
