This section, is dedicated to showing the reader the progress that has been made in Colombia on this topic, and aims to provide technical assistants, extension workers and coffee growers with the results of the investigations and the rationale of the recommendations of the FNC and Cenicafé on the management of coffee cultivation, in relation to the control of populations of the borer.Ĭoffee is produced in more than 50 countries in the world under a wide variety of agricultural ecosystems and agronomic practices. For this reason, the National Federation of Coffee Growers, has put a lot of effort into developing research programs for its control that allow the sustainability of Colombian coffee farming. ![]() relevant than in other parts of the world. In Colombia, the climatic conditions of the coffee zone and the different ecosystems in which coffee farming thrives make this problem even more. The coffee berry borer, Hypothenemus hampei (Ferrari), is the most serious pest that threatens coffee growing in the world, and for which coffee countries invest many economic resources in its management and control. Key words: Coffea arabica L., forest coffee, southwestern Ethiopia, insect pests, season. ![]() The present findings complement other research results meant for the conservation of remnant forest and its biodiversity especially to explore the natural enemies in these forest ecosystems. Generally, there were differences in insect pest incidence between and within forest coffee populations with regard to coffee leaf damaging insects and relatively low incidence observed compared to other coffee production systems. There is also high variation among major coffee leaf damaging insect during different seasons (rainy, rainy to dry transition, dry and dry to rainy season transition season). Among the frequently occurred and damage causing insect pests were Leucoplema doherthyi, Cryphiomystis aletreuta, coffee giant looper and Leucoptera species and had 72.20 ± 1.42, 14.41 ± 5.15, 10.73 ± 4.30 and 2.63 ± 1.24 proportion damage across forest coffee populations, respectively. Mean incidence data showed, significant different (P< 0.05) during different survey seasons within and between three forest coffee populations. ![]() Survey and damage assessment results reveal that, coffee leaf damaging insect pests in afromontane rainforests of Southwestern Ethiopia include 12 insect families from five insect orders. ![]() Based on general uniformity of forest coffee population, each forest coffee was stratified into three forest sites and 16 trees were systematically selected for leaf insect damage assessment. were conducted to investigate pest status and their damaging intensity in three (Yayu, Berhane-kontir and Bonga) forest coffee ecosystems. Accordingly, surveys on insect pest of coffee. Therefore, the present study was initiated to study the occurrence of coffee leaf damaging insect pests in the afromontane rainforest of southwestern Ethiopia. Insects are diverse and abundant in forest ecosystems, but poorly documented in afromontane rainforests in Southwestern Ethiopia where Coffea arabica L. ![]()
