Abstract

Fruit flies (Diptera: Tephritidae) are significant pests of fruit and vegetable crops worldwide. Despite their importance, some regions in South America remain under-researched regarding the fruit fly species that damage host plants and the parasitoids that provide their natural control. In this study, we investigated the interactions among host plants, fruit flies, and their larval parasitoids along two altitudinal gradients in Oxapampa, Pasco, a tropical Andean forest in Peru. Several samples of cultivable and non-cultivable ripe fruits were collected from ten orchards at low (800-950 m above sea level) and high (1750-1900 m above sea level) altitudes over a 2-year period. At high altitudes, we identified seven plant species hosting fruit flies. From these infested fruits, four species of Anastrepha and Ceratitis capitata emerged, while Doryctobracon crawfordii, D. areolatus, Utetes anastrephae, and Opius sp. (Hymenoptera: Braconidae) emerged from parasitizing fruit fly larvae. At low altitudes, eleven host plant species of fruit flies were identified, yielding seven Anastrepha species and parasitoids including D. crawfordii, D. areolatus, D. zeteki, and Ganaspis pelleranoi (Hymenoptera: Figitidae). We provide the first record of D. zetekii emerging from A. kulhmanni in South American sapote (Quararibea cordata), as well as the first extensive documentation of parasitoids in Anastrepha-infested fruits in Peru. Our findings enhance the limited knowledge of fruit flies and parasitoids on host plants in the Andean regions of South America, providing a baseline for future biological control practices in these environments.

秘鲁安第斯森林沿两个海拔梯度寄主植物中的果蝇(双翅目:蝗科)及其寄生蜂(膜翅目)。
果蝇(双翅目:蝗科)是世界范围内危害果蔬作物的重要害虫。尽管它们很重要,但在南美洲的一些地区,对破坏寄主植物的果蝇物种和提供自然控制的拟寄生物的研究仍然不足。在秘鲁帕斯科奥克斯帕帕热带安第斯森林中,研究了寄主植物、果蝇及其幼虫拟寄生物在两个海拔梯度上的相互作用。在2年的时间里,从海拔低(800-950米)和高(1750-1900米)的10个果园采集了若干可栽培和不可栽培的成熟果实样本。在高海拔地区,我们发现了七种寄生果蝇的植物。在这些被寄生的果实中,寄生出了小角蛾和头角蛾4种,寄生在果蝇幼虫上的有小角蛾、小角蛾、小角蛾和小角蛾等。在低海拔地区,共鉴定出11种寄主植物,包括7种蝇类和7种拟寄主植物,包括克劳弗氏蝇、微孔蝇、zeteki、pelleranoi(膜翅目:蜂科)。我们首次在南美洲的仙人掌(Quararibea cordata)中发现了zetekii d.h ulhmanni,并首次在秘鲁的anastrepha侵染的水果中发现了寄生蜂。我们的研究结果增强了对南美洲安第斯地区寄主植物上果蝇和拟寄生虫的有限认识,为未来在这些环境中的生物防治实践提供了基线。
