RED WEAVER ANTS, KERENGGA
Weaver ants may be red or green. The type we encounter in Malaysia is similar to the one in Thailand, the Red Weaver Ant.
Ants bite and Thailand’s Red Weaver Ants (Oecophylla smaragdina) are no exception. These red weaver ants are territorial and aggressive. When the ants bite you will certainly know about it. Rarely will you escape with just one ant bite as their amazing communication system can quickly gather a whole army to deal with your intrusion.
Thailand’s red weaver ants have definitely adopted the principle of ‘bite first, ask questions later’. Although weaver ants bite, they have a unique feature which gives them their name. The weaver ants bind leaves together using a “silk’ from their larvae, to form nests in which they care for their ant eggs.

Shooting borers with ants
By HILARY CHIEW
The mahogany is much sought after for fine furnishings because of its clear grain and beautiful reddish hue. The hard timber can resist rot and damage by termites, thus enhancing its commercial value. However, the tree is vulnerable to attack by the shoot borer. After almost eight decades of research spanning 23 countries, a sound pest management solution is still elusive, but the latest research by the Forest Research Institute of Malaysia may bring cheer to the timber industry.
TELL-TALE SIGN: The brownish substance on the terminal bud of the mahogany tree is the frass or secretion of the shoot borer’s larvae.
Ants to the rescue?
One of the proposed methods to control the shoot borer involves the use of natural enemies, including ants, according to a research paper, A preliminary study on the prospects for biological control of the mahogany shoot borer by ants, of which Lim is the lead author.
“A survey was conducted to determine if the presence of these ants had a deterrent effect on the occurrence of shoot borers on the trees,” says Lim who led the three-year IRPA (Intensive Research in Priority Areas) project which ended recently. Assisted by fellow entomologist Dr Laurence Kirton, Lim carried out the study in a plantation of one-year-old K. ivorensis located within a plantation near Slim River, Perak. The project received the support of plantation owner Lim Sun Heng of Maju Aik Sdn Bhd who is excited over the potential of the experiment.

STRAIGHT UP: Mahogany trees with straight stems like this one are the dream of mahogany entrepreneurs. But when larvae of mahogany shoot borers destroy the buds of the trees, the trees grow with deformed stems, which lower their economic value.
