The Used of Attractants from Coffee at Various Heights Traps to Control Coffee Berry Borer and Quality Test of Coffee Berry

Abstract

The coffee plant is a commodity that is widely grown in Toba Regency, Province of North Sumatera. Coffee berry borer (CBB) Hypothenemus hampei (Coleoptera: Scolytidae) is an essential pest in coffee plants which can reduce the quantity and quality of coffee fruit up to 50%. This research was to study the use of attractants derived from extract coffee bean and outer skin (pericarp) at various height traps to control CBB in Parsaoran Sibisa Village, Lumban Julu District, Toba Regency. This research method uses a factorial randomized block design with two treatments and three replications. For the first factor is the type of attractants (aqua-des, coffee beans and pericarp). The second factor is the height of the trap (0.5; 1.0 and 1.5 m). The results showed that the interaction of attactant type and trap height had no significant effect, but the attractiveness of coffee beans significantly affected CBB population trapped. The attractant of coffee beans caught 16.40 adults, 6.57 adults pericarp and 0.04 adults of distilled water. The best trap height is at 0.5 m with 8.50 adults followed by a height of 1.0 m and 1.5 m each with 8.28 adults and 6.24 adults.
