    Struktur Komunitas Hymenoptera Parasitoid Pada Ekosistem Sayuran dan Vegetasi Non-Crop di Sumatera Barat

    No full text
    Hymenoptera parasitoids have an important role in agroecosystem because of their ability in suppressing pest population. Their presences in the field are seen as the key to agricultural ecosystem. Their presence can be influenced by the availability of non-crop vegetation. Some adult Hymenoptera parasitoids require food in the form of pollen and nectar of wild flowers to ensure effective reproduction and longevity. The objective of this research is to study Hymenoptera parasitoid communities in vegetable field and non-crop vegetation at Alahan Panjang and Kayu tanduak agricultural landscapes. Insects were sampled by two trapping techniques (farmcop and sweep net) in one lines of transect for each landscape. Total of 62species from 19 families of Hymenoptera parasitoid were collected invegetable field and non-crop vegetation at Alahan Panjang and Kayu Tanduak landscape. Landscape structure affected the species richness, diversity and evenness of Hymenoptera parasitoid invegetable field and non-crop vegetation

    Understanding how the landscape structure affect the interaction between crops, pests and their natural enemies is a complex problem that can significantly impact on the success or failure of insect biological control. Hymenoptera parasitoids are particularly important natural enemies because of their great diversity and effectiveness as agents of biological control. The objective of this research is to study the diversity of Hymenoptera parasitoid on some vegetables and rice ecosystem in West Sumatera. Hymenoptera parasitoids were sampled using three trapping techniques (farmcop, insect net and yellow pan trap). Species accumulative curves, Jackknife-1 estimator, and indices of diversity were applied to analyze the data. Results indicated that there were 1522 specimen consist of 22 families and 148 species of Hymenoptera parasitoid on agricultural ecosystem in west Sumatera. Braconidae and Ichneumonidae were dominant Hymenoptera parasitoid family in vegetables ecosystem. Contrast, Mymaridae, Diapriidae, and Eulophidae were dominance of Hymenoptera parasitoid famili in rice ecosystem. Diversity of Hymenoptera parasitoid was influenced by the landscape structure. Species richness and diversity were higher in polyculture ecosystem than monoculture
