Abstract
In a survey involving the abundance of the parasites ofLeucoptera meyricki Chesq. in relation to the height of the canopy level from 4 sites (altitudes 1524–1676 m) 10 hymenopterans were reared. Of these 7 were parasites and 3 hyperparasites. The mines from which most parasites emerged were collected at 90, 150 and 210 cm above the ground. Capped and uncapped canopies provided different ecosystems for mine colonization by parasites, althoughL. meyricki infestations occurred at all height levels within the canopy. The most abundant parasite species at all sites wereAchrysocharella ritchiei Ferriere,Zagrammosoma variegatum Masi,Pediobius coffeicola Ferrière andAgeniaspis sp.
Résumé
A l'occasion d'un inventaire de l'abondance des parasites deLeucoptera meyricki Ghesq. selonla hauteur de la couronne des caféiers dans 4 sites (altitudes de 1 524 à 1 676 m), 10 hyménoptères ont été élevés. 7 d'entre eux sont parasites, les 3 autres hyperparasites. Les mines larvaires d'où la plupart des parasites fut obtenue ont été récoltées à 90, 150 et 210 cm au-dessus du sol. Les couronnes taillées et non taillées constituent des écosystèmes différents pour la colonisation des mines par les parasites, bien que les infestations parL. meyricki se produisent à tous les niveaux de la couronne. Les parasites les plus abondants dans tous les sites furentAchrysocharis ritchiei Ferrière,Zagrammo soma variegatum Massi,Pediobius coffeicola Ferrière etAgeniaspis sp.
