Abstract

This research was carried out in Beiwali Village, Bajawa District, Ngada Regency. The aim of
this research was to identify the types of pest insects, symptoms of damage caused by pests, the
population of pest insects on arabica S795 coffee plants in Beiwali Village, Bajawa District,
Ngada Regency. The method used in this research is a survey method. The types of data
collected are primary data and secondary data. Primary data was obtained by conducting
interviews with farmers at the research location and direct observation of arabica S795 coffee
plants and using traps in the form of coptan attractants and yellow traps, while secondary data
including rainfall, temperature and air humidity were obtained from the research location
villages and other agencies. The pest insects obtained were collected, grouped and put into

with symptoms of fruit slowly turning yellow and black sooty mold appearing. Meanwhile,
Aphis gossyipii was found in colonies under plant shoots which were below the surface of the
leaves but no signs of significant damage were found. The pest insect populations found were:
Hypothenemus hampei with a total of 184 individuals, Planococcus citri with a total of 166
individuals and Aphis gossyipii with a total of 32 individuals. The highest percentage of damage
intensity was caused by Hypothenemus hampei with a cumulative average of 14.13%, which was
included in the mild category. The cumulative average intensity of damage by Planococcus citri
was 0.88%, which was included in the mild category, while there was no damage to Aphis
