Studi Keanekaragaman Arthropoda Pada Ekosistem Pertanaman Buah Naga Merah (Hylocereus Polyrhizus) Di Desa Maku Kecamatan Dolo

SUMMARY

Ade Fitri (E28119325). Study of Arthropod Diversity in the Red Dragon Fruit Plant Ecosystem (Hylocereus polyrizus) Maku Village, Dolo District. (Supervised by Dr. Ir. Abd. Wahid M.Si, and Dr. Asrul, SP,MP)

Dragon fruit (Hylocereus sp.) is one of the tropical fruits that has high economic value and contains many nutrients that are beneficial for the body. Dragon fruit is a unique fruit, because dragon fruit is produced by cacti from the genera Hylocereus and Selenicereus. This study aims to determine the Diversity Index, Dominance Index and Abundance Index in dragon fruit plantations in Maku Village, Dolo District. And it is hoped that this study can provide initial information about several arthropods that attack dragon fruit plants as an initial step in controlling them. This research was carried out in a dragon fruit plantation in Maku Village, Dolo District, Sigi Regency. Then the identification of arthropods was carried out using a microscope at the Plant Pests and Diseases Laboratory, Faculty of Agriculture, Tadulako University, and comparing using images (photo scan application). This research was carried out from August 2023 to September 2023. This research was carried out using the method used in insect observation, namely scan sampling. The method of catching insects is done with 2 methods, namely the yellow trap method and the ground trap method (Pitfall trap). The identified insects are counted for type and number and then grouped based on characteristics to determine their role such as groups of pest insects, natural enemies (predators/parasitoids). The insect index on dragon fruit plants is 1,409 individuals consisting of 26 genera/morphospecies with 23 families from 11 orders, namely Hemiptera, Hymenoptera, Coleoptera, Orthoptera, Diptera, Lepidoptera, Odonata, Blattodea, Araneae, Heteroptera, and Diploda. The percentage of Arthropods based on Ecological Roles in Dragon Fruit Plants, insects that act as predators are 45%, insects that act as pests 39%, insects that act as decomposers 10%, insects that act as bioindicators 4%, and insects that act as decomposers 2%
