  • The oriental fruit moth (Grapholita molesta Busck) and the peach fruit moth (Carposina sasakii Matsumura) are the most severe insect pests affecting apple orchards in Korea. To prevent an outbreak of these two species and to control these agricultural insect pests, it is important to identify them accurately. However, it is hard to classify them when they were in the larval stage since they tunnel into the apple fruit. In this study, surface structures of the two species of larvae were observed using stereo microscope and scanning electron microscope. Distinct differences between the two species of larvae were found. The prothorax spiracles of oriental fruit moth larvae were approximately twice as large as those of peach fruit moth larvae. The arrangements of subventral setae, located around the proleg, were different between oriental fruit moth and peach fruit moth larvae. Furthermore, subdorsal setae of oriental fruit moth were located next to the spiracle on the 8th abdominal segment, while that of peach fruit moth was located above the spiracle. The identification of the two species of larvae observed in this study was confirmed using polymerase chain reaction-restriction fragment length polymorphism method. Surface structural differences are intrinsic characteristics for each species of larvae and can easily be identified using stereo microscope. These specificities will be helpful where a large number of field-collected larvae need to be identified routinely in pest control research.

  • On July 2009, 5 fly larvae were discovered inside the nose of a 76-year-old female. She was living in Cheonansi, and in a state of coma due to rupture of an aortic aneurysm. Surgery was performed on the day of admission, and the larvae were found 4 days later. By observing their posterior spiracle, the larvae were identified as Lucilia sericata. Considering the rapid development of this species, the infection was likely acquired during hospitalization. Further investigation on the hospital environment should be needed to know the origin of the infection.

  • The tadpoles of 12 Korean anuran species, including Bombina orientalis, Bufo gargarizans, B. stejnegeri, Hyla japonica, Kaloula borealis, Rana dybowskii, R. huanrenensis, R. coreana, R. nigromaculata, R. chosenica, R. rugosa, and R. catesbeiana, were classified based on their morphological characteristics. We collected eggs or tadpoles of the 12 Korean anuran species from Gangwon, Incheon, Chungcheong, and Gyeonggi districts in 2005 and 2006 breeding seasons. When the tadpoles reached at $27{\sim}37$ Gosner's developmental stages, we described morphological characteristics of the tadpoles of each anuran species and measured their physical parameters such as total length, body length, and body mass. After that, we chose 12 morphological characteristics to identify each species and to use them as classification keys such as eye location, caudal musculature pattern, spiracle location, oral disc morphology, and labial tooth row formula. In this paper, we presented classification keys, morphological characteristics, and drawings for the tadpoles of 12 anuran species.

  • 이산화염소 훈증 처리는 저곡해충에 대한 방제 가능성을 가지고 있다. 특히 체내로 독성 가스의 침투력을 높이기 위해 기문의 개방화를 유도하면 이 훈증 가스 처리 효과를 증가시킬 수 있다. 이 가설을 증명하기 위해 본 연구는 이산화염소 훈증 처리에 감수성을 보이는 화랑곡나방(Plodia interpunctella)을 대상으로 기문 개방 활동을 분석하였다. 화랑곡나방 유충의 기문은 모두 9쌍으로 앞가슴에 1쌍 그리고 복부에 8쌍을 각각 지니고 있다. 이들은 몸 내부에 가로 및 세로기관지와 연결된 구조를 지녔다. 기문 개방 유무는 염색액 침투 방법으로 판정하였으며 이를 토대로 분석한 결과 주변 온도 증가에 따라 기문 개방화는 약 60% 까지 증가하였다. 특히 이산화탄소에 노출되면 기문개방화는 약 95%까지 증가하였다. 반면에 이산화염소에 노출되면 화랑곡나방 유충의 기문은 대부분 닫혀 기문개방율이 약 25%로 줄었다. 이산화염소 처리에 이산화탄소를 추가한 결과 기문개방율은 이산화탄소 단독 처리만큼 크게 증가하였다. 이를 토대로 두 혼합 가스를 처리하여 살충효과를 분석한 결과 이산화염소 단독 처리에 비해 혼합처리가 현격하게 높은 살충력을 나타냈다.

  • Ophthalmomyiasis rarely occurs worldwide, and has not been reported in Korea. We present here a case of ophthalmomyiasis caused by Phormia sp. fly larva in an enucleated eye of a patient. In June 2010, a 50-year-old man was admitted to Dankook University Hospital for surgical excision of a malignant melanoma located in the right auricular area. He had a clinical history of enucleation of his right eye due to squamous cell carcinoma 5 years ago. During hospitalization, foreign body sensation developed in his right eye, and close examination revealed a fly larva inside the eye, which was evacuated. The larva was proved to be Phormia sp. based on the morphology of the posterior spiracle. Subsequently, no larva was found, and the postoperative course was uneventful without any complaints of further myiasis. This is the first case of ophthalmomyiasis among the literature in Korea, and also the first myiasis case caused by Phormia sp. in Korea.
