| Summary: | Termites are cellulose-eating soil fauna which is important in the tropics.
This insect which lives in colonies has diversity and high population abundance.
It plays an important role in decomposition, nutrient turnover and processes in
the soil. In Wanagama forest, there are several stands with different
environmental characteristics that affect the diversity of subterranean termites
species. The aim of the study was to know the diversity and abundance of
subterranean termites in the stand of Tectona grandis, Acacia mangium,
Eucalyptus sp.
The study was conducted in July 2013 (dry season), in plot 17
Wanagama. Subterranean termites sampling was done with a combination of
transect surveys methods and plot methods. As much as 2 transects were made in
each stand, with 6 plots on each transect. The measurement of environmental
factors consisted of soil moisture content, moisture content of litter, litter
thickness, light intensity, temperature, pH ( H2O ) of land, basal area, and ground
cover diversity .
The study found 5 species of subterranean termites (Hypotermes sp. A.,
Odontotermes longignathus, Macrotermes gilvus, Microtermes insperatus,
Pericapritermes semarangi) from 2 subfamilies (Macrotermitinae dan
Termitinae). Those 2 subfamilies were from 1 family (Termitidae). The more litter
thickness and dead wood existence caused the abundance of subterranean termites
in T. grandis stand (8.433 n/ha) was more than the one in Eucalyptus sp. stand
(6.333 n/ha) and A. mangium stand (2.267 n/ha) for the existence of litter and dead
wood can be a microhabitat that affects termites activity to nest and find its food.
Meanwhile, the more varied plant diversity and the more amount of soil and litter
moisture content could make the termites diversity in Eucalyptus sp. (1,275),
more than the one in A. mangium stand (1,169) and T. grandis stand (1,031). A
forest which had more varied plant and more water supply was the ideal habitat
for termites life because it could keep moisture condition favored by termites. |
