  • The ability of sunflower, bean, green perilla, and sesame to attract Metcalfa pruinosa was tested in both laboratory and field conditions. In the laboratory experiment, sunflowers showed the highest attractiveness to M. pruinosa nymphs and adults. These results were the same as those in the field experiment. Sunflowers showed the highest attractiveness among the four candidates as a trap plant for M. pruinosa, with comparable average attractiveness values for nymphs and adults to those in the laboratory. Young beans also showed high attractiveness to M. pruinosa, albeit lower than those of sunflowers. However, the attractiveness of mature beans was low. Sunflowers consistently (P < 0.05) showed significantly higher attractiveness than that of the other three plants, regardless of plant age. Thus, sunflowers would serve as a good trap plant for both the nymphs and adults of M. pruinosa.

  • The chimpanzee and gorilla are classified into hominidae, catarrhini, primates. These species are originated from Africa, so called African great apes. Recently, primatologists have classified that there are 2 species 5 subspecies of the chimpanzee and gorilla, respectively. Since the human genome project has been finished, the chimpanzee genome project has been launched to understand human evolution and genetic diseases. The sequences of chimpanzee chromosome 22 homologous to human chromosome 21 were completed, and then the Y chromosome of chimpanzee is being analyzed. Comparative analysis of human, chimpanzee and gorilla could provide the key for understanding of various human diseases and human origin. By detecting human specific-functional genes or mobile genetic elements (HERV, LINE, SINE) through primate research, we could understand what is human being\ulcorner gradually, For these comparative researches, we summarized fundamental knowledge of the feature, phylogeny and evolution of African great apes including humans.

Adult Trapping using Sex Attractants of Grapholita molesta, Carposina sasakii and Conogethes punctiferalis mixed in Single Dispensers (단일방출제에 섞인 혼합 성페로몬 미끼를 이용한 복숭아순나방, 복숭아심식나방, 복숭아명나방의 성충 포획)

  • Trapping efficacy of lures obtained by mixing sex pheromone attractants of two or three species in a single dispenser were evaluated in peach and apple orchards for three lepidopteran fruit borers, Grapholita molesta (GM), Carposina sasaki (CS), and Conogethes punctiferalis (CP) which use different chemicals as their sex attractants. In the peach orchard, the trapping efficacy of the mixed lures of GM and CS attractants were reduced for GM trapping, compared with the single GM lure. The population fluctuation patterns of GM were highly correlated between the single lure and all the mixed lures. In the apple orchard, the efficacy of all the mixed lures were not reduced for GM trapping. The trapping efficacy of all the mixed lures for CS trapping were not reduced compared with the CS single lure in both the peach and apple orchards. In the peach orchard, the population fluctuation patterns of CS were highly correlated between the single lure and the mixed lures. The efficacy of the mixed lures for CP trapping could not be determined because of the small number of caught samples. The results indicated that mixed lures could be utilized for monitoring of the annual adult emergence of two species, GM and CS.

  • Population dynamics in the vermicomposting bed was investigated. And harvesting efficiencies of earthworm attracting traps with different attractants, mesh sizes of net and covering materials was evaluated. Peak density of earthworm population was $5kg/m^2$ and therafter its desity kept $4.4{\sim}5.0kg/m^2$. It was evaluated that suitable mesh size of the net was 7mm and proper covering materials of the earthworm attracting trap was cotton quilt. The earthworm harvesting efficiency of trap with attractant was much higher than that of trap without attractant. With more amount of attractant in the trap and with longer setting period of trap onto the vermicomposting bed, the earthworm attracting trap harvested more earthworms. Crushed pear-peel attracted much more earthworms than paper mill sludge, but it was difficult to supply enough amount of crushed pear-peel for practical need. Sugar solution(10%) with tab water was proven to be an alternative to crushed pear-peel because its attracting effect on earthworm was as high as crushed pear-peel and it was easy to prepare and supply in large quantity.

  • The effects of insect capture were studied in a chestnut orchard using three different light traps (A, B, and C type) with various lamps. The mercury lamp trap captured 125 insect species, out of which 115 were chestnut pests. The B and C type light traps, comprising a Dulux-EL white lamp, were examined for their capturing ability. The type B trap attracted Coleopteran insects (83%), while type C captured Lepidopteran insects (73%). The mercury clarity lamp along with the type B light trap was most effective in attracting Curculio sikkimensis adults (mean, 9.8 adults), while the Dulux-EL lamp captured the highest number of Dichocrocis punctiferalis adults (mean, 10.2 adults) using the type C light trap. These results suggest that selection of the appropriate types of light traps and lamps based on the target pest species is critical in ensuring effective and eco-friendly control of the pest population.

  • Clearwing moths (Lepidoptera: Sesiidae) are economically important pests of fruit trees, such as apple, peach, and grape in Korea. Larvae feed on the phloem and cambium within tree branches of host plants. In this study, the seasonal fluctuation in male catches of four clearwing moths, Synanthedon haitangvora, S. bicingulata, Nokona regalis, and Glossosphecia romanovi, were monitored with the respective sex pheromone traps in Suwon for three years. In apple orchards, S. haitangvora males were captured from May to October, with two peaks in early June to middle June and late August to early September. Similarly, S. bicingulata males were trapped from May to October, with two peaks in late May and late August to middle September in peach orchards. In vineyards, N. regalis males were captured from late May to middle June with one peak in late May to early June, while G. romanovi males were trapped from early June to late July with one peak in late June to early July.
