The influence of attractant from coffe bean and outer skin of coffee to imago of coffee berry borer Hypothenemus hampei Ferr. (Coleoptera: Curculionidae) on the field

One of Environmentally friendly control of H. hampei is using the coffee attractant based on the content of organic volatile compounds (kairomone). The objective of this study was to determine the effect of coffeebean extracts and fruit peels as attractants on the traps of trapped female H. hampei . The study was conducted at the Small holders Coffee Plantation in Sukanalu Village, Barus Jahe District, Karo Regency, North Sumatra Province, Indonesia from May July 2018. The experiment was designed as Split Plot Design which consists of 2 factors. The first factor was the types of attractant (the attractant of coffee bean extract and the extraction of coffee pods ), while the second Factor was the concentration of attractants ( without attractants, 10%, 30% and 50% ) . The results showed that the best attractant was coffee bean extract with a concentration of 30% (99.59 adult). While 50% coffee fruit skin attractant can control H. hampei ( 60.91 adult) . The results also showed that type and concentration attractant, as well the interaction of both influences were very significant on the number of females of H. hampei trapped.
