In order to develop the artificial bait of trap for swimming crabs, the attracting effect was analyzed in the duration time of attracting effect, preference and shape recognition to the bait in the water tank and field experiments. According to the result which investigated the mean entrapped number of swimming crabs into the trap for each bait(mackerel, sardine and anchovy) in water tank experiments, the mean entrapped number was found to be higher in the trap with mackerel(6.9 ind.; 23.0%) than in other traps with sardine(5.2 ind.; 17.3%) and anchovy(3.4 ind.; 11.3%). In addition, the mean entrapped ratios of swimming crabs into the traps for 3 kinds of baits were estimated to be over 80% all in 5 hours after soaked in the water tank. For preference of swimming crabs to 3 kinds of baits, the trap with mackerel(6.9 ind.; 23.0%) was evaluated to be higher than the traps with sardine(2.8 ind.; 9.3%) and anchovy(0.2 ind.; 0.7%). In the field experiments, the mean entrapped number of swimming crabs into the trap with mackerel and sardine were found to be similar as 120 and 118 ind., but the trap with anchovy was only 85 ind.. According to the result which investigated the shape regnition of swimming crabs to the bait used mackerel, divided into 8 pieces, 16 pieces and grinded mass in water tank experiments, the mean entrapped number of swimming crabs into the traps that includes the mackerel divided into several pieces was significantly decreased. Moreover, by the presence of skin of mackerel for bait, there was a great difference in the entrapped number of swimming crabs. Therefore, it was thought that the swimming crab was attracted to the bait and entrapped into the trap would indicate that not only the chemical stimuli such as the attactant, but also the visual stimuli such as the shape recognition to the bait might be closely related.

Sex pheromone blends of large black chafer, Holotrichia parallela (Motschulasky), which consist of a major component L-isoleucine methyl ester (LIME) and a minor component (R)-(-)-linalool, showed different attractiveness depending on the mixing ratios of the two components in potato fields in South Korea. The best ratio for H. parallela attraction was 2.5:1 of LIME and (R)-(-)-linalool. The attraction ability of pheromone traps bated with 2.5:1 ratio did not drop up to 14m, but significantly decreased at 21m from H. parallela release point. Korean population of H. parallela showed almost same periodical activity to sex pheromone with that reported in Japan, which showing a circabidian periodicity of 48h cycle.

Catch of garden thrips, Frankliniella intonsa, on sticky traps was assessed by color and height in commercial plastic vinyl house strawberry crops grown on 40-㎝-high trellises. Yellow, blue and white sticky cards were tested for color attractiveness, and upper (50 ㎝), lower (10 ㎝ above the floor) and ground were for height. At each height, trapped thrips on yellow, blue and white were significantly different. Blue sticky cards were significantly greater than traps on yellow and white. The trapped thrips were also significantly greatest at 50 ㎝ above the floor, less at lower and ground. However, there is no significantly different the population of garden thrips on the flower in each tested site.

골프장 주요 해충인 주황긴다리풍뎅이 (Ectinohoplia rufipes)성충의 기주식물을 실내와 골프장 현지조사를 통하여 알아본 결과, 실내에서는 41科 101種 제공 식물 중 27科 61種을 ,골프장에서는 8科 27種 식물을 식해하는 것이 관찰됨으로서 총 29科 84種 으로 기록되었다. 수종 별 피해도를 골프장에서 조사한 결과, 골프장에 따라 가해하는 수종이나 피해 도에서 차이가 있었 고, 사방오리나무와 벚나무, 은목서, 아그배나무에서 피해도가 높았다 사방오리나무와 벚나무, 은목 서 잎을 이용한 실내에서의 선호성 비교에서는 사방오리나무에서의 피해엽율이 58.1%로 가장 높 았다. 주황긴다리풍뎅이 성충의 유인율은 피해를 받은 사방오리나무의 잎에서는 45.3%, 인위적으 로 상처를 낸 잎에서는 26.5%, 주황긴다리풍뎅이에 대한 노출이 전혀 없었던 무(無)피해 잎에서 는 4.0%, 주황긴다리풍뎅이는 있었으나 피해가 없었던 비(非)피해 잎에서는 12.9%로 피해엽에 많이 유인 되었다. 한편, 무피해 잎과 주황긴다리풍뎅이의 피해를 받은 잎, 무 피해 잎에 주황긴다리풍뎅이 성충의 배설물을 처리한 잎에 대한 피해엽율을 조사한 결과 각각 30.5%, 67.5%, 2.0%로서 이미 피해를 받은 잎에 대한 선호성이 뚜렷하였다.

솔나방의 light-trap에 의한 유인력 비교와 시간별 유인효과, 유인되는 성간비교 및 유아등종의 개발과 trap형에 고나한 실험에서 다음과 같은 결과를 얻었다. 1. 솔나방의 인인성은 U.V. 파장 에서 가장 유인효과가 좋았다. 2. 솔나방의 유인 최성시각은 20:00-22:00시로서 그때의 유인수는 전체 유인수의 가 이 시각에 유인되었다. 3. 적색, 황색등에서는 유인효과를 볼수 없었다. 4. Blacklight-trap의 경우 20:00-22:00시까지 유인되는 성비는 로서 female의 유인수가 더 많았다. 5. 기상조건과 솔나방의 유인효과와는 상관관계가 없었다.

In order to effectively control the Ricania sp., we investigated the light response to adults and developed an adult capturing device using light with superior attractiveness. The preference among six light sources such as daylight color, green, etc. for the Ricania sp. adult was favored with daylight color 97 > black 79 = red 79 = blue 79 > green 24 > yellow 13. We have developed an adult catching device using the most preferred daylight colors and behavioral habits of the Ricania sp.. The capture device consisted of two daylight compact lamps (30W, 20W), a yellow plate, and a catcher using water, and caught about 700 individuals a day. The capturing device has a large amount of capturing because adult is activity at high nighttime temperatures, but the capturing amount decreased significantly when the temperature dropped below 23℃. More than 85% of the Ricania sp. adults were trapped for 3 hours from 19:00 to 23:00. Therefore, it is considered that the adult capturing device for the control of Ricania sp. is used from mid July to late August when the night temperature is over 23℃, and lights up from 19:00 to 23:00.

현재 부산항은 위기에 처해 있다. 외부적으로는 세계적인 경제불황으로 전반적인 물동량 감소도 있지만, 신항개장 이래로 북항과 신항 간의 물동량 유치를 위한 출혈경쟁으로 터미널 채산성이 악화되고 부산항 이미지가 크게 손상되고 있다는 점이다. 이는 근본적으로 부산북항이 하역사위주의 운영사로 난립되어 있기 때문이다. 이에 따라, 본 연구에서는 부산항의 문제점을 해결할 수 있는 북항터미널의 통합유인요인이 실질적으로 부산항의 경쟁력제고에 얼마나 영향을 미치는 지를 실증분석하였다. 실증분석결과에 의하면, 북항터미널 운영사를 통합하여 글로벌 터미널 하여야만 선사서비스능력, 항만생산성을 제고시켜 긍극적으로 물동량 증대와 동북아허브항만화에 기여할 것으로 나타나고 있어 부산항 경쟁력제고를 위해 부산북항 터미널의 통합이 정책적으로 시급함을 보여주고 있다.
