Species composition of herbivorous insects and ants on trees in the plantations of durian Durio zibethinus and citrus fruits Citrus amblycarpa in Tarakan Island of Borneo Species composition of herbivorous insects and ants on trees in the plantations of durian Durio zibethinus and citrus fruits Citrus amblycarpa in Tarakan Island of Borneo 大河原, 恭祐 79132 70283091 Rahim, Abdul 89098 Ohkawara, Kyohsuke 89099 70283091 70283091 herbivorous insects ant community durian citrus plantation In the tropics, the specific insect communities are observed in the fruit plantations as one form of agroforestry systems. The information on the communities of herbivorous insects as pests and ants as pest-control agents could be useful in facilitating effective management of plantations. Durian Durio zibethinus and citrus fruits Citrus amblycarpa are traditionally grown as agricultural products in the North Kalimantan region of Borneo, though the information on herbivorous insects and ants remains scant. In this study, we assessed the species composition and densities of herbivorous insects and ants inhabiting on trees in the plantations of durian and citrus fruits in Tarakan Island of North Kalimantan. From 2016 to 2017, 55649 individuals of herbivores comprised of 61 species and 64360 ant workers comprised of 25 species were collected by treebeating sampling on 59 durian and 63 citrus trees in three plantation sites (A-C). In citrus fruit trees, aphid Toxoptera citridida was dominant in the herbivore communities. While, in durian trees, more than 80% of herbivores was occupied by various herbivore groups, leaf beetle, moth, mealybug, psyllid and leafhopper. In ants, more than 60% of ants collected in each site was occupied by three species Tapinoma melanocephalum, Technomyrmex albipes, and Oecophylla smaragdina. NMDS analyses showed the patterns of classification in herbivorous insect and ant communities were similar: the groups in site C could be classified, independent on the groups in site A and B. Probably, it may be caused by the environmental factors in site C. Otherwise, the characteristics of herbivores community are possibly affected by any interactions with ants, resulting in the association among the structures of herbivore and ant communities. Our data could provide useful information for the pest control activities in the plantations of durian and citrus fruits in North Kalimantan. departmental bulletin paper Institute of Science and Engineering, Kanazawa University 2019 VoR application/pdf The Science Reports of Kanazawa University 63 45 58 The Science Reports of Kanazawa University 2433-040X https://kanazawa-u.repo.nii.ac.jp/record/49557/files/Sci_Rep63-004.pdf https://doi.org/10.24517/00055869 http://hdl.handle.net/2297/00055869 https://kanazawa-u.repo.nii.ac.jp/records/49557 eng http://scirep.w3.kanazawa-u.ac.jp/ http://scirep.w3.kanazawa-u.ac.jp/
