Abstract: DE LAS ALAS, JEREMIE M. April 1999. Survey of Insect Pests and Diseases Associated with Soursop in Cavite and Batangas. Thesis, Bachelor of Science in Agriculture major in Crop Protection, Entomology, Department of Crop Protection, College of Agriculture, Forestry, Environment and Natural Resources, Cavite State University, Indang, Cavite. Adviser: Dr. Evelyn Oquias Singson. A survey of insect pests and diseases associated with soursop was conducted at the Cavite State University and Banilad, Nasugbu, Batangas. Six insect pests, four natural enemies and two diseases were found associated with soursop in Cavite. On the other hand, two insect pest, three natural enemies and three diseases were observed in Banilad, Nasugbu, Batangas. In both study sites, Stephanitis typicus, Leptocentrus manilaensis, and Drosophila melanogaster were the common pests. The coccinelid predator, Chilocorus circumdatus, was observed in both study sites. The most prevalent and damaging disease of soursop was dry rot. The population fluctuation of the insect pest was recorded and correlated with environmental factors. Correlation analysis showed an inverse relationship between pest population and rainfall and relative humidity in Cavite. However, in Batangas, only rainfall showed linearity with insect pests.
