회화나무(Sophora japonica)를 가해하는 줄마디가지나방(Chiasmia cinerearia (Bremer et Grey))의 발생 및 생태적 특성
권건형,이민섭,엄훈식,김용훈,권영대,Kwon, Gun-Hyung,Lee, Min-Seop,Eom, Hoon-Sik,Kim, Yong-Hun,Kwon, Young-Dae 한국응용곤충학회 2016 한국응용곤충학회지 Vol.55 No.1
자나방과(Geometridae), 가지나방아과(Ennominae)에 속하는 줄마디가지나방(Chiasmia cinerearia)은 중부지방의 회화나무 가로수 및 조경수를 가해하는 대표적인 수목 해충이다. 본 연구의 결과 줄마디가지나방은 주로 잎 위에 250~300개의 알을 무더기로 산란하였으며, 유충은 총 5령기를 거쳐 용화되었다. 성충은 5월 초순과 7월 말경에 2회 우화하였으며, 1세대 경과일수는 약 48일로 조사되었다. 유충의 몸길이는 25~30 mm 정도이며 연녹색을 띠고 복부의 옆선은 황색이었다. 성충의 날개편 길이는 30~35 mm 정도이며 회갈색을 띠며 앞날개 외횡선을 중심으로 4각형의 무늬가 무리지어 있는 것이 특징이다. Chiasmia cinerearia (Bremer et Grey) belonging to the subfamily Ennominae(Lepidoptera: Geometridae) is a new forestry pest attacking to Sophora japonica in Gyeonggi province. Chiasmia cinerearia oviposited about 250~300 eggs per female on leaves. Larva had five instar stages. Adults emerged twice a year in early May and late July. The period of one generation was about 48 days. Body length of larvae was 25~30 mm and body color was light green with dark yellow lateral lines in abdomen. The wingspan of adults was 30 to 35 mm in length. The color of forewings was greyish brown with quadrilateral patterns on outer lines.

생활권 수목에 살포된 살충제 Fenitrothion의 이용자 노출 및 위해성 평가
권건형 ( Gun-hyung Kwon ),문준관 ( Joon-kwan Moon ),정윤미 ( Yun-mi Jung ),이민섭 ( Min-seop Lee ),이진흥 ( Jin-heung Lee ),이근섭 ( Geun-seop Lee ),권영대 ( Young-dae Kwon ) 한국산림과학회(구 한국임학회) 2018 한국산림과학회지 Vol.107 No.2
도시림, 생활림, 가로수, 도시공원 등 국민들의 일상생활을 하는 구역이나 장소에 위치한 생활권 수목 식재지에서의 농약 살포는 농약 살포자의 농약 노출 문제뿐만 아니라 농약의 살포 후 생활권 수목과 접촉하는 불특정 시민들도 지속적인 농약 노출이 문제가 될 수 있다. 본 연구에서는 생활권 수목의 관리를 위해 관행적으로 가장 많이 살포되는 살충제인 Fenitrothion을 회양목에 살포하고 일정시간별로 손 노출량, 잎 잔류량, 호흡 노출량을 측정한 뒤, 위해성 평가 수식(MOS: margin of safety)을 이용하여 체중별 안전 노출시간을 분석하였다. 그 결과, 살포된 Fenitrothion의 손을 통한 전이량이 급격하게 떨어지고 호흡노출량이 측정되지 않는 48시간 이전까지는 농약노출에 대한 주의가 필요할 것으로 판단되었다. Pesticides are widely sprayed by the growers in street trees and planting areas which include urban forests, community forests and city parks to control pests. Spraying pesticides not only affect the people who sprayed but also affect the unspecified citizens who’s are exposed to pesticides sprayed trees by contact or inhalation. A few studies have been conducted to measure the amount of pesticides in forest area but no studies have been conducted to measure the pesticide amount in tree in public living space. So, in our study, we investigated the amount of pesticides in cotton gloves, in leaf residue, and respiratory exposure for a certain period of time after applying Fenitrothion EC to Korean boxweed tree (Buxus Koreana) to know the safety time of pesticides after spraying. We found that, up to 4d, there was no significant difference of the amount of Fenitrothion on leaves. But the amount of pesticides on gloves was significantly higher on 1h (510.1 μg) and 24h (405.4 μg) than 48h (45.0 μg) after spraying. The amount of pesticides on inhalation was also significantly higher in 1 h (0.2 μg) and 24 h (0.1 μg) than 48 h after spraying. After 48h, we did not find pesticides amount in inhalation. Thus, we was considered necessary to pay attention to 48h after spraying of pesticide Fenitrothion.

스프링클러시스템을 이용한 잣나무 채종원의 구과해충 방제에 관한 연구
정상배(Sang-Bae Chung),송병민(Byong-Min Song),권건형(Gun-Hyung Kwon) 한국자원식물학회 2006 한국자원식물학회지 Vol.19 No.1
In order to prevent cones from being damaged by cone insects, Gravitarmata margarotana and Dioryctria abietella, sprinkler system was installed on the Pinus koraiensis Seed Orchard. Such a test was conducted at Chung-ju, Chungcheong buk-do, Korea in 2002. Insectides of Diflubenzuron 25% WP ×2500 and Cyfluthrin 2%EC ×1000 were sprayed at fifteen-day and twenty-day intervals during the period of insects adult occurrence by sprinkler system. The Gravitarmata margarotana generally emerged for about 53 days from middle April to early June, and peak emergence was 10 days from April 20 to April 30. Dioryctria abietella generally emerged for about 108 days from late April to early August, and peak emergence was 10 days from May 20 to May 30. Damage rate of cones were 8.7~9.7% and 10.9~12.7% on average with crown insecticide spraying with Cyfluthrin and Diflubenzuron, while 67.5% when not treated. Control effectiveness of this insecticide spraying was 85.6~87.1% and 83.9%와 81.2%, respectively. When it considers the forest environment, it is recommended diflubenzuron which is low toxic pesticide. In conclusion, effectual times and number of diflubenzuron 25% WP application with sprinkler system against cone insects were from early May through late August and six times at twenty-day interval.
