Light traps equipped with light emitting diodes (LEDs) have been applied to manage some phototactic insect pests. The diamondback moth, Plutella xylostella, is a cosmopolitan insect pest to be seriously harmful to many cruciferous plants. The present research focused on evaluating the phototactic behavior responses of the moths to several wavelengths and photon flux densities of LED lights under laboratory and field conditions. The results from the laboratory showed that the highest phototactic behavior responses of P. xylostella moths were recorded for UV (380 nm) LED light under 1.5 µmol m − 2 s − 1 and 2.5 µmol m − 2 s − 1 . The moths were more attracted to light traps equipped with 4 LEDs and 6 LEDs of 380 nm, respectively, between 20:00 and 22:00 than the other groups and night times in the field. The finding from the field was consistent with the results from the laboratory. We found that the 380 nm LED light results in the strongest attraction rate of the moths by 92.4 % and the moths caught in light trap with the UV LEDs was 1.62 times more than that with a black light. These data clearly demonstrate that P. xylostella moths have a high sensitivity to 380 nm, therefore, a 380 nm LED light trap could be useful for monitoring and controlling the moths.

Langerhans 세포 조직구증(LCH, Langerhans\` Cell Histiocytosis)은 Langerhans\` cell histiocyte의 이상 증식을 특징으로 하는 원인 불명의 질환이다. 이 질환은 eosinophilic granuloma, Hand-Sch ller-Christian씨 병, Letterer-Siwe병을 포함하는 것으로 과거에는 histiocytosis X로 불리던 질환이다. 피부, 림프절, 골, 골수 및 체내 모든 조직과 기관을 침범할 수 있으나 국내에서 흉벽에서 발생된 예는 보고된 증례가 많지않다. 18개월 된 남자 환아에서 흉벽의 늑골에서 기원하여 골용해 소견을 동반한 종괴가 있어 수술적 절제한 후 LCH로 확진된 증례가 있어 문헌고찰과 함께 보고하는 바이다 Langerhans\` Cell Histiocytosis(LCH) is a disease of unknown origin, characterized by abnormal proliferation of Langerhans\` cells. Previously, it has been called histiocytosis X, which included eosinophilic granuloma, Hand-Sch ller-Christian\`s disease, and Letterer-Siwe disease. Any organs or tissues such as skin, lymph nodes, bone and bone marrow can be involved. However, LCH of chest wall is rarely reported in our country. We experienced a 18 month old male child, who had osteolytic lesion involving the rib with axillary lymph node metastasis. The tumor was confirmed as LCH after surgery.
