In plantations and seed orchards, spacing could play a
significant role in insect diversity and abundance. Hamphrey
et al. (1999) reported that diversity of syrphids (hoverflies) in
open canopy stands, which are characterized by high levels of
understory, is greater than in dense closed canopy stands. They
suggested that the open stands with diverse understory provide
a greater source of adult food and suitable breeding sites for
syrphids. In addition, Fermon et al. (2000) reported that the
species richness and diversity indices of butterflies in liberation
thinning (broader spacing) are higher than those in monodominant
tree plantations. We believe that our results from this
study of teak are in agreement with results from these other teak
studies. We found higher species diversity and abundance of
