Invasion of termite, M. gilvus, on peper mounds and effect on the growth of pepper was studied at Natar Experimental Garden in Lampung during 1986-1987. The study was carried out by opening the mounds of pepper with various types of plant support. Food preference of termite was observed by offering wood of "dadap duri" (Erythrina indica), "kapok" (Ceiba pentandra), "dadap licin" (Erythrina lithosperma), "gamal" (Glyricidia maculata), "lamtorogung" (Leucaena leucocephala), "mendaru" (Urandra corniculata) and pepper stem (Piper nigrum) to live on. Results showed that the invasion of the termite occurred on each block where pepper grow on mounds. Average number of mounds damaged by M. gilvus was 53,21 percent, with an intensity of 40.60 percent, resulting in stunted growth of the pepper. The termite of M. gilvus invaded the mounds planted with "kapok", "mendaru", "dadap licin", and "gamal" as pepper support, causing approximately 50-57.50 percent, damage. Actually its preference, i.e: "dadap duri", "kapok", "dadap licin", pepper stem, "gamal", "lamtorogung", and "mendaru" and the volume of wood consumed in a 5 month period was 106.67, 33.50, 33.17, 20.33, 19.50, 13.83 and 1.17 cm3 respectively
