Abstract

Several Arthropod pests have been collected and identified on coffee, Coffea arabica. L. in Ethiopia, but only a few are economically important. Based on the plant part the pests feed on, they can be categorized as flower and flower bud feeders, leaf feeders, berry (fruit) feeders, twig and branch feeders borers and stem (trunk) borers.

Antestia, Antestiopsis intricata (Ghesquiere) Carayon and blotch leafminer, Leucoptera Caffeina (Washbourn) are the two most important pests feeding mainly on young fruits and leaves respectively.

Studies made regarding biology, feeding habits, population dynamics and natural enemies (parasitoids and predators) of Antestia are described. The buildup of this insect starts in March and reaches its peak around May/June although slight variations have been observed in various coffee growing areas. Young berries are the most preferred part of the plant. Antestia eggs 45–50% are attacked mainly by three species of parasistoids of which Asolcus suranus (Nixon) was found to be the most important.

Résumé

Plusieurs prédateurs d'arthropodes ont été prélevés et identifiés sur le café (Coffea arabica L.) en Ethiopie. Peu seulement ont une importance économique. Suivant les parties de la plante, sur lesquelles ils se nourissent, on classe ces ravageurs en: mangeurs de fleurs, de bouton de fleurs, de feuilles, de baies (fruits), de brindilles, de branches et en perceurs de tiges (troncs). Antestia-Antestiopsis intricata (Gherquiere et Carayon) et Leucoptera caffeina sont les deux ravageurs les plus importants. Ils se nourissent principalement des jeunes fruits, ou respectivement des feuilles. Leur biologie, leur régime alimentaire et la dynamique de leur population ont été étudiés. La description des ennemis naturels (parasites et prédateurs) de Antestia est présentée. L'accumulation de ces insectes commence en mars et atteint son maximum entre mai et juin, bien que nous avons observé des petites variations dans différentes régions de plantation de café. Les jeunes baies sont la partie préférée de la plante. 45–50% des oeufs d'Antestia sont attaqués principalement par trois espèces de parasitoids. Nous avons déterminé qu'Asolcus suranus (Nixon) est l'espèce la plus importante.
