The feeding preference of cigarette beetles, Lasioderma serricorne F., was tested using various leaf litters. The number of the trapped L. serricome was 45.25$\pm$10.44 at flue-cured leaf tobacco, Nicotiana tabacum L., 23.50$\pm$6.0 at chinese juniper, Juniperus chinensis L., 1l.75$\pm$4.99 at oak, Qqercus acutissiuma C., and 1l.50$\pm$2.52 at rice-straw, (Oryza. sativa L.). The response of oviposition was 93.20$\pm$26.22 at flue-cured leaf tobacco, 53.60$\pm$11.82 at chinese juniper, 48.20$\pm$20.90 at oriental arborvitae, Thuja orientalis L., 31.80$\pm$18.10 at cherry-tree, Prunus serrulata var. spontanea M., and 29.40$\pm$13.7 at rice-straw. However, the oviposition was respectively low at gingko, Ginkgo biloba L.,(5.40$\pm$2.97), turf grass, Zoysia japonica S., (5.20$\pm$13.7), and oak (3.00$\pm$l.41). The augmentation was maximum at chinese juniper (27.33$\pm$19.44 of emerged adults) followed by Magnolia obovata (8.50$\pm$9.33). Fifty percent of the tested species leaf litters including cherry-tree did not show any augmentation. The adult activities after hibernation were primarily found in May and June at Kwangju and Suwon, and in April at Chungju. The field activity of L. serricome at Suwon was mostly lower than that at other places, except in August at Chungju. The first appearance of L. serricome was observed earlier at Chungju and Kwangju than at Suwon, and the frequency of insect appearance was high in July, August, and September. L. serricome could hibernate by feeding on many kinds of plant leaf litters and it's population could be maintained in the open field in Korea.

Insecticidal effect or sulfuryl fluoride ($SO_2F_2$) to cigarette beetle, Lasiodema serricorne (F.), was studied in two different containers, one was 1m$^3$(without cardboard block) and the other was 0.5m$^3$(with cardboard block). Adults and larvae were transferred into a small metal can before placed in the containers. Each can was held for 8, 24, 48, 72, and 96 hours after $SO_2F_2$(10, 20, 30, and 40 g/$\ell$) treatment. All adults were killed in an 1m$^3$container. Larval mortality was 99 to 100% when the dosage of SO$_2$F$_2$was 10 and 20 g/$\ell$. Cardboard was attached between two 0.5m$^3$ containers ; one was fumigation area and the other was insect area. SO$_2$F$_2$ penetrated cardboard within 24 hours in most trials. $SO_2F_2$could affect all adults and larvae regardless of their susceptibility. All adults were killed at 8 hours in a 0.5m$^3$ container. But low mortality of larvae was recorded at 8 hours when small dosage was treated (30% in 10 g/$\ell$, 87.2% in 20 g/$\ell$). The mortality was increased as SO$_2$F$_2$ dosage increased. Six different metals (stainless, copper, brass, aluminum, iron, and zinc) were also tested to study metal corrosion and discoloration. No corrosion and discoloration was observed in most metals treated with $SO_2F_2$.

국내 유통 중인 한약재 대부분을 수입에 의존하고 있으나, 관리시설이 빈약하여 해충들에게 쉽게 노출될 수 있는 환경에 놓여 있다. 이 연구는 총 67과 134속 158종의 저장 한약재들을 대상으로 이들에서 발생하고 있는 저장물해충들을 조사하였다. 그 결과, Cassia 속의 육계, Juniperus 속의 자단향 그리고 Artemisia 속 애엽을 비롯한 44종의 한약재들에서는 곤충의 발생을 확인할 수 없었다. 한약재들에서 나타난 해충들의 발생빈도는 쌀머리대장 (A. advena) 12.3%, 권연벌레 (L. serricorne) 11.5%, 머리대장가는납작벌레 (O. surinamensis) 10.3%, 거짓쌀도둑거저리 (T. castaneum) 9.4%, 인삼벌레 (S. paniceum) 8.4% 그리고 화랑곡나방 (P. interpunctella) 7.9% 순이었다. 또한 이들 곤충들은 저장 중인 한약재들 중에서도 뿌리 또는 뿌리줄기 형태의 한약재들을 가장 선호한 것으로 보였다. 이 연구는 천연물 연구자들에게 곤충들이 발생하지 않았던 한약재들에 대한 기본 정보를 제공해줌으로써 향후 이들이 살충활성 또는 훈증활성물질을 탐색하는데 있어 이들 한약재들을 우선적으로 검토할 수 있는 유용한 자료로서 활용될 수 있을 것이다.
