After the eradication <strong>of</strong> Macrotermes <strong>and</strong> Odontotermes colonies, activities <strong>of</strong><br />
Hypotermes were observed. This species is known to be beneficial, as Hypotermes<br />
termites cause no damage to rubber trees, eat fallen leaves <strong>of</strong> rubber trees to make<br />
organic manure, <strong>and</strong> s<strong>of</strong>ten the soil physically.<br />
Our bait formulations containing <strong>molybdenum</strong> <strong>and</strong> <strong>tungsten</strong> compounds utilize as<br />
active ingredients metal elements distributed on the earth <strong>and</strong> are not possessed with<br />
residual toxicity as organic chlorine-based termiticides, proving promising as a new<br />
termiticide. Especially, applications <strong>of</strong> the <strong>baits</strong> to rubber plantations suffering severe<br />
damages do a lot for the social welfare <strong>and</strong> their early practical use is expected.<br />
