Abstract
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.
