Effects of a gel bait on the suppression of noxious Crematogaster rogenhoferi Mayr, 1879 (Formicidae: Myrmicinae) in Sri Lanka

Crematogaster rogenhoferi Mayr, 1879 in a home garden in Sri Lanka was reported to cause health hazards and an investigation was conducted from February to November in 2016 to list the tree species bearing its nests and to record the nest structure, nest intensity and colony demography for the evalu...
