Abstract

Citrus is a horticultural fruit commodity that is in great demand by the public. Citrus has a high economic value, in the form of fresh or processed fruit. Dekopon citrus is a mandarin sweet citrus that has no seeds. The citrus is a hybrid of kiyomi and ponkan developed in Japan in 1972. Dekopon citrus tastes sweet, is large in size and has a bump at the base of the fruit. The bump is a characteristic that distinguishes it from other citrus. This study aims to determine the species diversity of phytophagous arthropods and natural enemies on dekopon citrus plants in Pulau Semambu Village, Ogan Ilir, South Sumatra. The research was conducted from September to November 2024. The research was conducted using the census method in citrus plants in Semambu Island village. The results showed that there were 14 species of arthropods found in dekopon citrus plants. The 14 species consisted of 9 phytophagous insects, 2 predator species, 2 spider species and 1 pollinator. Phytophagous found were Geomyza tripunctata, Trialeurodes vaporariorum, Aphis spiraecola, Anoplocnemis phasiana, Sanurus flavovenosus, Lawana candida, Planococcus citri, Scopula parodites and Phyllocnistis citrella. Predators found were Cheilomenes sexmaculata, Halmus chalybeus, Oxyopes macilentus, Phintella vittata and pollinator insects found were Amata huebneri. The species diversity index value in dekopon citrus plants shows 1.72, the species dominance index value shows 0.34, the species evenness index value shows 0.65. The average intensity of pest attack on dekopon citrus plants is around 38.5%.
