The investigation on Epilachna varivestis defoliation of Phaseolus vegetables was carried out at Chimaltenango in Guatemala high land area in September, 2004. The degree of defoliation on the green bean strain of P. vulgaris was little (11 plants per 1200 plants) and no damage on the black bean strain in the field of ICTA (Instituto de Ciencia y Tecnologia Agricolas). E. varivestis defoliation was 3-18.9% at Phaseolus fields of farms in Chimaltenango, where the rate of parasitized larvae (mummies) was 46.7%. Pupa of the tachinid fly was found from mummy collected in Chimaltenango. The mean number of eggs per egg mass was 40.3 (mini=27, max=50). A few adults with the variable spot pattern of the elytra were found and were observed to copulate with the normal type.
