摘要

Ficus deltoidea, commonly known as Mas Cotek, is a member of the Moraceae family and originates from Southeast Asia. With 13 documented varieties, it engages in obligate mutualism with the fig wasp (Agaonidae). This study delves into the mutualistic relationship between F. deltoidea and its pollinators, explicitly focusing on Blastophaga sp. fig wasps found in F. deltoidea var. deltoidea, within the Ficus genus. The research explores the host specificity of Blastophaga sp. from var. deltoidea across seven different F. deltoidea varieties, aiming to see the degree of specificity on this fig wasp. The methodology entails thoroughly examining figs and interactions with fig wasps in pot-maintained trees where a donor male tree was surrounded by seven other varieties. Findings reveal that Blastophaga sp. from var. deltoidea demonstrates a tendency for host sharing, accessing not only var. deltoidea but also var. angustifolia, var. trengganuensis, var. bilobata, var. kunstleri, and var. motleyana. These findings challenge traditional assumptions of strict host specificity and emphasize the intricate nature of mutualistic interactions within the Ficus species. This research provides valuable insights into the dynamics of gene flow mediated by pollinators, stressing the necessity for further molecular characterization to deepen our understanding of the mechanisms underlying these interactions.
