Until now, only two species of Dichaetomyia Malloch have been recorded in the Korean fauna. In this study, we report two unrecorded species for the first time in Korea. External photographs, key to Korean species and taxonomic information are presented herein.

Helina Robineau-Desvoidy (어리가시집파리속, 신칭)은 집파리과(Muscidae) 가시집파리아과(Phaoniinae)에 속하는 큰 분류군 중 하나 로 전세계에 540여종이 기록되어 있다. 그러나 한국에서는 아직까지 기록이 이루어진 바가 없으며, 이번 연구를 통해 한국미기록속 Helina Robineau-Desvoidy 및 미기록종 H. deleta (Stein, 1914), H. evecta (Harris, 1780), H. subpubiseta Xue, 1986을 처음으로 보고한다. 또한, 분류 학적 정보, 형태학적 사진 및 검색표를 작성하였다.

파리목(Diptera) 집파리과(Muscidae)에 속하는 토마토어리줄기집파리(Atherigona orientalis)는 열대·아열대 지역에서 분포하며 고추, 토마토 등 기주 특이성이 없어 여러 식물에 흔히 발견되는 해충이다. 현재까지 우리나라 작물에 피해는 보고되지 않았으나 국외 사례로 볼 때 우리나라 작물에서도 큰 피해를 유발할 것으로 예상되어 식물방역법상 관리해충으로 지정하여 관리하였다. 2016년 경상북도 의 성군에서 첫 국내 분포가 보고되었다. 우리는 이 종의 지역별 분포 현황 등을 확인하기 위하여, 2017년 4월부터 10월까지 전국 각지에 트랩을 설치하여 분포 조사를 실시하였다. 조사결과 총 2,601개체가 전국적으로 조사되어 국내에 널리 분포하고 있음이 확인되었다.

The repellency to female Stomoxys calcitrans (L.) of 21 essential oils alone or in combination with Calophyllum inophyllum nut oil (tamanu oil) was examined using a skin bioassay. Results were compared with those following treatment with the commonly used repellent DEET (N,N-diethyl-3-methylbenzamide). As judged by the protection time (PT) to first bite at 0.5 mg cm-2, patchouli (3.67 h) was the most effective essential oil, followed by clove bud, lovage root, clove leaf and thyme white essential oils (3.50-2.12 h). Thyme red, oregano and geranium essential oils exhibited moderate protection time (PT, 1.24-1.11 h). At 0.25 mg cm-2, effective protection time of clove bud, clove leaf and lovage root essential oils was about 1 h. The protection times of DEET were 4.47 and 2.17h at 0.5 and 0.25 mg cm-2 respectively. The remarkable increase in the protection time were produced by binary mixtures of five essential oils (clove bud, clove leaf, thyme white, patchouli and savory) and tamanu oil (0.25:2.0 mg cm-2) compared with those of either the constituted essential oil, tamanu oil or DEET alone, indicating the involvement in synergy. These essential oils, tamanu oil and binary mixtures did not cause any adverse effects on the human volunteers at 0.5 mg cm-2 except savory oil. Thus binary mixtures of essential oils and tamanu oil described merit further study as potential insect repellents for protection from humans and domestic animals from biting and nuisance caused by S. calcitrans.

The repellent constituents of essential oils from Zanthoxylum armatum (Rutaceae) seed and Zanthoxylum piperitum fruit against female Stomoxys calcitrans were analyzed by gas chromatography and gas chromatography-mass spectrometry. The repellency of two Zanthoxylum essential oils and 11 oil compounds against female S. calcitrans was examined using a skin bioassay. Results were compared with those of the most widely used repellent DEET. Both Z. armatum seed and Z. piperitum fruit oils provided complete and good protection from fly bites for 30 min at 0.4 and 0.2 mg/cm2, respectively. At 0.05 mg/cm2, both oils gave ca 70 and 40% repellency at 30 and 60 min post-treatment, respectively, whereas DEET provided 83 and 73% protection. Of test compounds, cuminaldehyde at 0.05 mg/cm2 gave 92 and 69% repellency at 10 and 30 min post-treatment, respectively, whereas 1,8-cineole, and citronellal provided approx. 76% repellency at 10 min. The Zanthoxylum oils and their constituents, particularly cuminaldehyde, merit further study as potential insect repellents for the protection from humans and domestic animals from biting and nuisance caused by S. calcitrans.

유기인체 살충제인 Pyraclofos에 저항성인 집파리를 profenofs로 7세대 도태시킨 P-Pro 계통을 이용하여 Pro-fenofos 저항성의 유전학적인 분석을 행하였다. Profenofos저항성은 불완전우성으로 나타났기 때문에 가시돌연변이로 각 염색체를 표식한 감수성 ac, ar, bwb, ye, snp 계통을 이용하여 male-backcross에의한 연쇄군분석을 한 결과, 이 계통의 profenofos 저항성의 우성유전자는 각 염색체에 고루 존재하지만 제 2 염색체와제 5염색체 상의 유전자에 크게 지배받으면 웅성결정인자 M은 제 3염색체와 관련이 있는 것으로 나타났다.
