本研究的目的是确定食果幼虫的寄生蜂种类，并描述三营养相互作用，涉及野生水果，食果昆虫和它们的天敌Adolpho杜克森林保护区（RFAD）（马瑙斯，AM，巴西）。收集在四个1平方公里的象限的角落里的RFAD。野生水果是在森林内的通往每个收集区的小径和环绕象限的小径上收集的，每侧距离小径最多5米。将果实放置在塑料容器中，容器上覆盖有薄织物，底部有蛭石层，以允许苍蝇或寄生虫出现。采集到7种茧蜂，分布于Opiinae中：Doryctobracon areolatus（Szepligeti，1911），Utetes anastrephae（Viereck，1913）和Opius sp.，Alysiinae：本文报道了Anastrephae（Muesebeck，1958）、Phaenocarpa carripa Wharton and Carrejo，1999、Itera delicata Papp，1969和Asobara sp.方斑矛茧蜂是最常见的，寄生的蝇类数量最多，幼虫在取食威氏微囊藻果实时的寄生率最高。采到的拟盾甲藻分别属于Aganaspis nordlanderi Wharton，1998和A. pelleranoi（Brethes，1924）.所有15个三栖组合都是巴西亚马逊地区的新记录。苹果园是苹果幼虫寄生蜂的重要自然宿主。
This study aimed to identify parasitoid species of frugivorous larvae and to describe the tritrophic interactions involving wild fruits, frugivorous insects and their natural enemies at Adolpho Ducke Forest Reserve (RFAD) (Manaus, AM, Brazil). Collections were performed in four 1 km 2 quadrants in the corners of the RFAD. The wild fruits were collected inside the forest in access trails leading to each collection area and in trails that surrounded the quadrants, up to five metres from the trail on each side. The fruits were placed in plastic containers covered with thin fabric, with a vermiculite layer on the base to allow the emergence of flies or parasitoids. Seven Braconidae species were collected, distributed among Opiinae: Doryctobracon areolatus (Szepligeti, 1911), Utetes anastrephae (Viereck, 1913), and Opius sp., and Alysiinae: Asobara anastrephae (Muesebeck, 1958), Phaenocarpa pericarpa Wharton and Carrejo, 1999, Idiasta delicata Papp, 1969, and Asobara sp. Parasitism rates by braconids and figitids are presented. Doryctobracon areolatus was the most frequent, parasitizing the highest number of fly species, and showing the highest parasitism percentage in larvae feeding on Micropholis williamii fruits. The collected figitids belong to Aganaspis nordlanderi Wharton, 1998 and A. pelleranoi (Brethes, 1924). All 15 tritrophic associations are new records for the Brazilian Amazon region. The RFAD is an important natural reservoir of frugivorous larvae parasitoids.
