The presence of two species of Neozygites (Zygomycetes: Entomophthorales) in the Philippines is documented. Epizootics due to Neozygites fresenii (Nowakowski) Remau diere and Keller were observed on Aphis craccivora Koch populations on Gliricidia sepium (Jacq.) Steud. and string beans, Vigna sesquipedalis Fruw., and on A. citricola van de Goot infesting Mikania cordata (Burm.f.) B.C. Rob., both in 1994, in ViSCA, Baybay, Leyte. Also in 1994, epizootics due to N. fumosa (Speare) Remaudiere and Keller were also observed on the mealybug, Coccidohystrix insolita (Green) infesting eggplant (Solanum melongena L.) in Inopacan and later on unidentified mealybugs on Sida rhombifolia L. Epizootics of both N. fresenii and N. fumosa resulted to drastic reduction in the aphid and mealybug populations. Enhancing the occurrence of these fungi may have potential in the biological control of these pests
