오리엔탈과실파리(Bactrocera dorsalis)는 주요 검역 대상으로 지정된 해충이다. 이 해충에 대한 고감도 모니터링과 진단 기술이 초기 방역 처리에 요구된다. 본 연구는 오리엔탈과실파리를 유인하여 치사시킬 목적으로 메틸유제놀과 생물농약을 혼합한 왁스형 방출기를 제작하였다. 본 연구는 또한 5종의 주요 검역 과실파리(오리엔탈과실파리, 오이과실파리, 퀸즐랜드과실파리, 말레이시아과실파리, 지중해과실파리)에 대한 PCR 진단프라이머를 개발하였다. 이상의 모니터링용 왁스방출기과 분자진단기술을 말레이시아 코타키나발루 지역에서 실증 시험하였다.

Oriental fruit fly, Bactrocera dorsalis, is one of the serious pests of fruit throughout the world. Two regional populations (Bangladeshi and Malaysia) were collected using methyl eugenol lure and one laboratory population was obtained from Thailand. Three populations were compared in cytochrome b (CYB) cytochrome oxidase I (COI) sequences. COI sequences were highly homologous. However, CYB sequences were polymorphic and used to discriminate these regional populations by a phylogenetic analysis. In CYB phylogeny analysis, Malaysia and Thailand populations were clustered and Bangladeshi population was separated

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 Kunans National University have collected the samples of oriental fruit fly in East Asian countries, Vietnam, Philippines, Myanmar, China, Cambodia, India and Nepal. 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).
