Abstract: MADRAZO, RACHEL S. Influence of Temperature and Relative Humidity to Coffee Pests and their Natural Enemies Undergraduate Thesis, Bachelor of Science in Agriculture major in Crop Science, Cavite State University, Indang, Cavite, June 2019. Adviser: Dr. Evelyn O. Singson. The study was conducted at two locations: Non-shaded and shaded areas at the National Coffee Research Development and Extension Center (NCRDEC). This study was conducted for 10 months, from June 2018 to March 2019. This study aimed to: identify the different insect pests and natural enemies of coffee in non-shaded and shaded areas in the coffee plantation; determine infestation rate of coffee pests in non-shaded and shaded areas; and determine the effect of temperature and relative humidity on coffee pests and their natural enemies The insect pests collected and observed belong to order Hemiptera (green coffee scale and aphids). Coleoptera (beetles), Lepidoptera (butterflies and moths), Orthoptera (grasshopper), and Diptera (flies). Meanwhile, natural enemies commonly belong to order Hymenoptera (Wasps) and Coleoptera (Malaysian lady beetle). Infestation rate of common insect pests show that Coffee berry borer is higher in non-shaded area while coffee green scale is higher in shaded area. The result of the study show that temperature has significant influence on the number of insect pests. The statistical analysis reveal that for every increase per unit of temperature, there is a double increase in species of the insect pests. However, relative humidity is not an indicator of population of natural enemies and insect pests
