BIO-ECOLOGY OF H.HAMPEI IN COFFEE PLANTATION IN SUMBUL AND SIDIKALANG DISTRICTS, NORTHERN OF SUMATERA, INDONESIA.

Coffee berry borer (Hypothenemus hampei Ferr.) can be controlled using attractant trap which comes from the leaves and bark of coffee beans. The purpose of this study was to determine Bio-ecology of coffee berry borer (CBB), Hypothetamus hampei and ability to extract and rind of coffee as an attractant for imago fruit borer coffee with different levels of concentration. This research was conducted in the district and sub-district Sumbul and Sidikalang from August 2016 to October 2016. The results showed Bio-ecology of H. hampei pests that can be observed from the development of the egg, pupa and imago of H.hampei in Sidikalang and Sumbul, Dairi. Attractant trap of chlorogenic acid from leaves and bark of the coffee fruit is most effective in controlling the pest CBB in the field of ten repetitions recorded from 7 replicates very significant, consisting of the S3, S4, S6, S7, S8, S9 and S10 (p <0:00 -0.02) in Sumbul and Sidikalang. Developments of H. hampei affected by temperature and the availability of the coffee fruit. Factors influencing the development of H. hampei namely; continuous supply of fruit from generation to generation; the shade is too dense resulting in high humidity; and fulfilled the host plant consisting of Tephrosia sp, Centrosoma sp, Oxicanthus sp. The use of attractants chlorogenic acid leaves and rind of coffee pest control of CBB (H.hampei) is one effort in keeping the coffee commodity Dairi, North Sumatra.
