Use of volcanic debris as physical barrier against the Philippine milk termite (Isoptera: Rhinotermitidae)

Abstract

Workers of the Philippine milk termite (Coptotermes vastator Light) were tested for their abilities to tunnel and penetrate barriers consisting of uniform and mixed particles of lahar from Mt. Pinatubo. Particle diameter in the range of 1.18 to 2.36 mm prevented C. vastator from penetrating the lahar barrier. Repellency tests showed that lahar particles were neither repellent nor toxic to C. vastator. When several sizes in the diameter range 1.18-2.36 were uniformly mixed, the resultant barrier effectively prevented penetration of the termites. Field evaluations using mixed particle sizes 1.18-2.36 mm were also effective in preventing tunneling of field colonies of C. vastator.
