        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, is highly polyphagous pest that damages over 400 plant species, including commercially grown crops and fruits. It was first described in Taiwan and has since invaded Japan and China. In 2021, B. dorsalis was reported on Jeju Island in the Republic of Korea (ROK). To investigate its origin and understand its colonization pathway in ROK, the genetic characteristics were analyzed by using mitochondrial genes. The study analyzed the haplotypes and genetic differences among populations oriental fruit flies collected from Southeast Aisa, including Thailand, Taiwan, and Vietnam. The mitochondrial genes cytochrome oxidase subunit I (COI) and cytochrome B (CytB) were used for the analysis. The results showed that B. dorsalis had high levels of haplotype diversity among species. No major haplotype was found among populations. The present study enhances our understanding of the haplotype diversity of B. dorsalis in neighboring countries of ROK. This will expand our knowledge of the source of origin and invasive pathway for B. dorsalis.

        Fruit Flies (Diptera: Tephritidae) are polyphagous, highly invasive pests in which female adults lay eggs under the skin of fruit and larvae damage the fruit. Among them, the Oriental Fruit Fly, Bactrocera dorsalis (Hendel) was first reported in Taiwan and is distributed throughout much of Southeast Asia, including Vietnam, as well as on the African continent and in the Pacific region. In order to prevent the introduction of pests into country, the Animal and Plant Quarantine Agency has designated them as prohibited pests and is conducting surveillance and investigation on their occurrence. The experimental countries were Taiwan and Vietnam, and statistical analysis was conducted based on the number of B. dorsalis caught by setting up traps for about 8 months. Methly eugenol (ME; 4-allyl-1,2-dimethoxy-benzene) is a widely distributed natural plant and is used because it strongly attracts males of B. dorsalis. The experiments aimed to verify the effect of attractant formulations (liquid, solid, wax) and traps (Delta trap, Lynfield trap, Steiner trap) on B. dorsalis.

        The oriental fruit fly, Bactrocera dorsalis, is one of important agricultural pests that attack a wide range of fruits and vegetables. Adult female can cause direct damage by laying eggs under the skin of fruits and vegetables. The eggs hatch into larvae that feed in the decaying flesh of the agricultural crops. Damaged fruits and vegetables quickly become inedible or dropto the ground. We investigated the oviposition characteristics of B. dorsalis on twelve fruits and seven vegetables. B. dorsalis marked the oviposition places on every crop tested. B. dorsalis laid eggs into the fruits and vegetables except lemon and passionfruit. We examined the adult emergence from infested crops.

        노랑비취알락하늘소(가칭)의 제주 유입과 정착을 보고하는 논문에서 오리엔탈과실파리에 대하여 “제주지역에 유입되어 현재 발견되고 있 다”라고 잘못된 인용을 하고 있는 것이 발견되었다. 다행히도 해당 문장이 빨리 발견되어 “제주지역에 유입될 가능성이 있는”으로 수정되었다. 이 를 계기로 검역적으로 민감한 해충의 국내분포여부에 대하여 기술하는 경우 매우 신중하게 검증해야할 필요가 있음을 연구자들에게 강조하고자 한 다. 클라이멕스 모델의 저온 스트레스 지수로 추정한 결과 오리엔탈과실파리는 2022~2023년 겨울 제주에서 생존이 불가능한 것으로 예측되었다. 그러나 노랑비취알락하늘소는 2023년 겨울 영하의 기온을 겪고 월동후 여름철 발생이 확인되었으며 정착에 성공한 것으로 판단된다.

        본 연구는 국내 금지급 과실파리인 오리엔탈과실파리(Bactrocera dorsalis)에 대한 유전적 변이를 분석하였다. 이를 위해 오리엔탈과실파리 가 자생하는 대만 지역을 대상으로 2019년 동일한 시기(3일간: 7월 30일~8월 1일)에 서로 다른 세 지역(타이페이, 타이중, 카오슝)에서 과실파리류를 채집하여 나이 변이 및 미토콘드리아 서열 변이를 각각 비교하였다. 세 지역에서 채집된 오리엔탈과실파리는 1,085마리로서 메틸유제놀 유인제에 모두 유인되었으며, 큐루어 유인제에는 30마리의 오이과실파리(Zeugodacus cucurbitae) 및 1마리의 타우과실파리(Bactrocera tau)만 채집 되었다. 단백질먹이 유인제에는 총 6마리가 포획되었으며 이 가운데 오리엔탈과실파리는 1마리가 포함되었으며 나머지는 오이과실파리였다. 오리 엔탈과실파리 수컷의 머리에는 테린이 포함되었으며 나이가 증가함에 따라 각 머리에는 32 μg에서 59 μg까지 테린 함량이 증가하였다. 대만 세 지역의 수컷 집단들은 테린 양에 차이를 나타냈으며, 카오슝 집단이 타이페이와 타이중 집단에 비해 적은 테린 양을 보유하였다. 이들 세 지역 사이에 유전적 거리가 RAPD (random amplified polymorphic DNA)를 이용하여 분석되었으며 타이페이 집단이 타이중 및 카오슝 집단들과 차이를 나타내는 것으로 나타났다. 유전적 변이는 미토콘드리아의 cytochrome oxidase I (CO-I)과 NADH dehydrogenase I (ND-I)을 각각 비교 하였다. CO-I 영역 가운데 360개 염기서열을 비교한 결과 7.8%의 염기서열 변이를 나타냈다. ND-I 영역을 비교한 결과 213개 염기서열 가운데 6.6%의 염기서열 변이를 보였다. 이들 변이 서열을 대만 지역에 발생하는 오리엔탈과실파리의 특이적 SNP (single nucleotide polymorphism) 마커로 개발하는 데 추천한다.

        In the 21st century, the risk of the exotic pest being invaded is increasing due to the rise of trading activities. Oriental fruit fly, Bactrocera dorsalis (Diptera: Tephritidae), has been considered to very destructive invader as it is highly intrusive and has a wide host range. In this study, 2,299 samples were collected from 88 locations in 12 countries by quarantine and investigation. Among them, 608 individuals (including B. correcta) were used for COI DNA barcoding analysis based on Neighbor Joining method with P-distance model. Population genetics analysis was conducted for 510 individuals selected from 47 locations of 12 Southeast Asian countries using 15 microsatellite loci. The barcoding analysis resulted in that any clade was not clustered according to a geographical isolation but indicated geographically mixed populations. Population genetics analysis showed shared genetic structure between neighboring countries across borders. Genetic structure of most Korean quarantine groups was more similar to that of Taiwan, China and Thailand in the order of appearance than other countries.

        The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. The effects of temperature on stage-specific development were investigated at eight constant temperatures (13.0, 14.4, 16.2, 19.5, 23.8, 27.7, 31.8 and 34.8℃). Stage-specific lower developmental thresholds and thermal constants were determined using linear regression. The lower and higher temperature threshold (TL and TH) were estimated using the Sharpe-Schoolfield-Ikemoto (SSI) model. The daily adult emergence frequency of B. dorsalis was estimated in relation to adult age and temperature. Thermal performance was compared among B. dorsalis populations from different locations in Taiwan.
