Diversity of Fruit Flies on Three Varieties of Mango in Kuningan Regency, West Java, Indonesia

Abstract

Fruit flies (Bactrocera spp.) are the major pests on mangoes that constrain the efforts to increase the production and quality of mangoes, causing yield losses of up to 100%. Kuningan Regency is one of the largest mango-producing areas in West Java. However, there is no study about the species of fruit fly in the mango plantation at Kuningan Regency, West Java. This study aimed to fruit fly inventory on Gedong Gincu, Arumanis, and Cengkir mangoes. The research used a survey method and was analyzed using descriptive analysis. Purposive sampling was used to determine mango samples by randomly selecting fruits that were attacked by fruit flies from mango fields owned by farmers, wholesalers, and markets in Sukadana Village, Ciawigebang District, Kuningan Regency, West Java. The samples were taken to the Plant Pest Laboratory at Universitas Padjadjaran for incubation till the appearance of imago. The findings showed that the Bactrocera dorsalis complex consisted of B. dorsalis, B. carambolae, and interspecific crosses. The fruit fly diversity index was considerably low (0.21<H‘<0.53). B. dorsalis was determined to be the predominant species in all mango variety and locations, with a value of 95.12%.
