Abstract

At Alemaya in eastern Ethiopia, tef (Eragrostis tef) was found to be attacked by a complex of seven shootfly species, five species belonging to the family Chloropidae and two to Muscidae. Atherigona hyalinipennis (Diptera: Muscidae) was economically the most important species in the shootfly complex of the crop. It caused 42–58% damage to growing panicles in different varieties of tef, which resulted in an estimated loss of 378–522 kg/ha. The average incubation period of eggs, developmental periods of larvae and pupae of A. hyalinipennis were 3.0, 12.7 and 9.6 days respectively, and the total life cycle was completed in less than a month in the laboratory. Larval parasitism by Neotrichoporoides nyemitawus ranged from 6.7 to 18.5%. Peak activity of A. hyalinipennis in the region was in August to September.

Résumé

On a remarqué qu'à Alemaya, à l'Est de l'Ethiopie, le teff (Eragrostis tef) était attaqué par un complexe de sept espèces de mouches des pousses dont cinq espèces de la famille des Chloropidae et deux autres appartenant à la famille des Muscidae. Parmi ces insectes, Atherigona hyalinipennis (Diptera: Muscidae) était économiquement l'espèce la plus importante. Il causait de 42 à 58% de dégâts aux panicules en croissance au sein de différentes variétés de teff, avec des pertes de rendement estimées à 378–522 kg/ha. La durée moyenne de la période d'incubation des oeufs, la durée de développement larvaire et nymphal de A. hyalinipennis étaient de 3, 0, 12, 7 et 9 jours respectivement, tandis que le cycle biologique était bouclée à moins d'un mois dans les conditions de laboratoire. Le taux de parasitisme par les larves de Neotrichoporoides nyemitawus se rangeait de 6, 7 à 18,5%. Le pic d'activité de A. hyalinipennis dans la région étudiée, était situé d'août à septembre.
