Evaluation of Coffee Hybrid Varieties Against Major Coffee Insect Pests at Teppi, Southwestern, Ethiopia

Abstract

Coffee, originated in Ethiopia is utilized in a number of ways. It is grown in more than 50 countries around the world. With cultivation, marketing, export and processing of the crop a millions of people depends on for livelihood. Insect pest is the major challenge of coffee production in Ethiopia. The insect pest evaluation of coffee hybrid variety trial was under taken during the year 2013 (2005 E.C) for the objective evaluation of coffee hybrid variety trial for insect pest tolerant at Teppi, Southwestern Ethiopia. From the evaluation, we understand that there is a correlation between insect pest attack, canopy width and number of primary branches. The other all vegetative parameters had no relationship with insect pest occurrence. Geisha is highly infected with Coffee blotch leaf minor. Geisha was susceptible to coffee serpentine leaf minor in addition to coffee blotch leaf minor. For the next coffee hybridization study the following hybrid parents were not suitable for insect tolerance: HC-1, HC-3, HC-4, HC-5, HC-7 and HC-13. For the future study, in addition to morphological parameters, the biochemical content of the leaf responsible for insect pest attraction need attention.
