Aphid species found on citrus in Ogan Komering Ilir District, South Sumatra, Indonesia

Abstract

Abstract Citrus is an economically valuable plantation crop and has high market opportunities. In Southeast Asia, Indonesia is the second largest citrus importer after Malaysia, with an import volume of 160,254 tons; however, various obstacles limiting the cultivation of citrus plants cannot be separated from pests that can affect citrus quality and reduce citrus production. One of the obstacles is insect attacks such as aphids. Therefore, this study aims to determine the species of aphids in citrus. This research was conducted from May to June 2023 in Ogan Komering Ilir Regency using a direct observation method in the field. Observations were made on the parts attacked by aphids and symptoms of attack. The results showed that three species from 1 family of aphids were found. The species found were Toxoptera aurantii, Toxoptera citricidus, and Toxoptera citricola from the Aphididae family. The highest species found in the study was T. aurantii, with 861 individuals, and the lowest species found was T. citricola, with 29 individuals. Aphid species were found mainly on Citrus microcarpa and least on Citrus grandis.
