ABSTRACT
Data are presented, from the literature, 1) on the occurrence of insect-pathogenic viruses and protozoa on Lobesia botrana (Denis and Schiffermueller) and Eupoecilia ambiguella (Huebner), 2) on the beneficial effect on Lobesia larvae and adults of grapes infected in the laboratory with Botrytis cinerea Pers., 3) on the occurrence of diapause in Lobesia under summerlike conditions, and 4) on the suitability of host plants other than the grapevine for larval growth. The possible effects of those conditions and/or factors and of certain cultural practices on berry moth population density are discussed within the frame of integrated pest control in vineyards.
