Abstract

Canopy ants were examined in terms of a number of species and species composition between in high
and low disturbance sites of lowland tropical rainforest at Ton Nga Chang Wildlife Sanctuary, Songkhla
province, Thailand, from November 2001 to November 2002. A permanent plot of 100x100 m² was set up and divided into 100 sub-units (10x10m²) on each study site. Pyrethroid fogging was two monthly applied
to collect ants on three trees at random in a permanent plot. A total of 118 morphospecies in 29 genera
belonging to six subfamilies were identified. The Formicinae subfamily found the highest species numbers
(64 species) followed by Myrmicinae (32 species), Pseudomyrmecinae (10 species), Ponerinae (6 species),
Dolichoderinae (5 species) and Aenictinae (1 species). Myrmicinae and Ponerinae showed a significant
difference of mean species number between sites (P<0.05) while Formicinae and Myrmicinae also showed a
significant difference of mean species number between months (P<0.05). However, there were no interactions
between sites and months in any subfamily.
