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 $SO_2F_2$.

Most oriental medicinal plants in domestic markets have been imported, but these medicines are being easily exposed to many insect pests because of the poorness of storage facilities. This study was carried out to identify stored products insect pests occurring in 158 storage medicinal plants belonging to 134 genera of 67 families. No insect pests were not observed in 44 medicinal plants including Artemisia argyi Levl. et Vant., Cassia sieboldii Presl., and Juniperus chinensis L. Most commonly observed stored products insect pests in the surveyed medicinal plants were the order of as follows; Ahasverus advena(Waltl) 12.3%, Lasioderma serricorne F. 11.5%, Oryzaephilus surinamensis L. 10.3%, Tribolium castaneum (Herbst) 9.4%, Stegobium paniceum L. 8.4%, and Plodia interpunctella(Hbner) 7.9%. And these insects also are likely to prefer more root or rhizome part than the other ones. Based on these basic survey results, natural products researchers can obtain an important information in finding an insecticidal or fumigant compounds contained in the medicinal plants which any insect pests do not attack.
