Oriental fruit flies (Bactrocera dorsalis) are one of the most important pests in horticulture worldwide. The distribution information of this species is not easy to be found as it is scattered in many forms of publications such as books, journals, and research reports. The study was conducted by collecting data from various resources, analyzing the information, and interpreting the results. As a result, B. dorsalis was confirmed to be distributed in a total of 82 countries, and the distribution status of each country is presented by dividing it into present (widespread, localized, few occurrences, under eradication) and absent (eradicated, confirmed by survey, intercepted only, invalid presence record). This review is very useful for biologists, entomologists, as well as practitioners of plant protection.

The oriental fruit fly, Bactrocera dorsalis (Hendel), has potential of serious damage to various vegetables or fruits, especially genus of Citrus, such as mandarin orange and tangerine in Korea, where its larvae do damages. Animal and Plant Quarantin Agency of Korea and Animsl Systematics Laboratory of Kunsans National University have collected the samples of oriental fruit fly in East Asian countries, Vietnam, Philippines, Myanmar, China, Cambodia, India Nepal and Laos. To confirm genetic differences and structure of B. dorsalis population samples collected from those countries, we analyzed 192 individuals from 28 locations over 7 countries using 15 microsatellite loci. In total samples, number of different alleles, number of effective alleles and Shannon's Information Index were 6.421±0.364 (standard error, SE), 3.664±0.137 (SE) and 0.902±0.030 (SE), respectively. Grand means (±SE) of observed and expected heterozygosity over all loci and populations were 0.534 (±0.018) and 0.597 (±0.017), respectively. Among all populations, Fst values ranged from 0.016 to 0.705 with averaging 0.194 (±0.026).
