Abstract

Many species of fungi under the order Entomophorales are important pathogens of arthropods often resulting in high mortalities and natural control of field populations of insects and mites. Recognizing the presence of these fungi may aid in developing better management strategy to control these pests. This paper is a review of the various studies on Philippine Entomopthorales. Early and recent identification of entomopathogenic fungi was done in collaboration with foreign scientists. A total of 19 species under 9 genera are now included in the record of Philippine Entomophthorales. Of these species, the most common are Neozygites fresenii (Nowakowski) Remaudiere and Keller infecting aphids and Zoophthora radicans (Brefeld) Batko infecting several insect species. Six species under Batkoa, Entomophthora, Furia, and Neozygites are cited as recently described. Batkoa (Entomophaga) bukidnonensis (Villacarlos and Widing) Villacarlos is a new combination. The potential of Batkoa amrascae and N.fresenii as biological control agents was discussed in relation to their biological characteristics. Epizootiology of these species was also described together with N.heteropsyllae, Z.radicans, Pandora blunkii (Lakon and Zimm.) Humber. Weather conditions and host density affect the occurrence of epizootics in the insect population. Entomophthorales are highly-density-dependent; hence, they remain unnoticed when the insect population is low. Two isolates of N.fresenii differ in their virulence to certain aphid species and in the length of their capillicondiophore. The possibility of using the latter character to identify these isolates, together with other future research based on information presented, is discussed.
