ants are appreciated for their control of pests in plantation crops. However,
the ants ? nest building may have negative impacts on trees. In this study we tested
the effect of ant densities and nest building on the leaf performance of mango trees.
Trees were divided into three groups: trees without ants, trees with low and trees with
high ant densities. Subsequently, the total number of leaves, the proportion of leaves
used for nest construction, and tree growth was compared between these groups. The
percentage of leaves used for nests was between 0.42-1.2 % (mean = 0.7%±0.02) and
the total number of leaves and tree growth was not significantly different between
trees with and without ants. Further, leaf performance was compared between shoots
with and without ant nests and between leaves in or outside ant nests. The number
of leaves and lost leaves per shoot, leaf size
, leaf
condition (withered), leaf longevity
and hemipteran infection was compared between groups. In the dry season nest-shoots
held more leaves than shoots without nests despite nest-shoots showed more lost
leaves. Leaves in nests were smaller than other leaves, more likely to wither and more
often infested with scales. However, smaller nest-leaf size was probably due to the ants ?
preference for young leaves and the higher incidence of withering resulting as leaves in
nests cannot fall to the ground. In conclusion, the costs associated to ant nests were low
and did not affect the overall number of leaves per tree nor tree growth.Oecophylla
