정상배,김철수 한국임학회 2000 한국산림과학회지 Vol.89 No.5

The damage by the black-tipped sawfly, Acantholyda posticalis posticalis, has been increasing all over the area of Korean pine(Pinus koraicnsis)stands in Korean peninsula. This study was conducted to provide basic information for the management and control of this pest by investigating the feeding quantity of pine needles during the larval stage. The results were summarized as follows : The total needles damaged in the larval stage of the black-tipped sawfly were 9,584㎜ in length on an average and those of female and male were 11,774㎜ and 7,394㎜, respectively. The total length ingested actually was 7,797㎜ and it was equivalent to 81.4% of the total length damaged. Early larval stage showed a little feeding and it was equivalent to 17% of total quantity. On the contrary, the feeding quantity in late larval stages of fourth and fifth instars amounted to 83%. The number of the frass excreted per larva was about 1,160, and the difference between male and female was not showed, whereas it showed remarkable difference among larval instars.

The damage by the black-tipped sawfly, Acantholyda posticalis posticalis Matsumura, has been increasing at several locations in central part of the Korean peninsula. This study was undertaken at selected plot in localities of Kapyung-gun, Kyunggi province. The purpose of the study was to provide basic information for integrated control of this pest and to determine the economic threshold by investigating the effect of biomass and production by the damage of Black-tipped sawfly for korean white pine, Pinus koraiensis S. et Z. The results obtained were as follows; 1. The damage was heavier at the higher half of the crown than the lower; vertical distribution of the dry weight of the damaged trees above soil surface showed L-type distribution whereas that of healthy trees showed C-type distribution. 2. Growth of the total dry weight of aboveground was reduced when more than 20% of the needles were destroyed. It was mainly due to the loss of needle weight rather than that of the trunk weight or the branch weight. 3. Reduction rate of the annual net production of aboveground coincided with that of the volume increment was reduced when more than 50% of the needles were destroyed after three years of initiation of the sawfly infestation.

The damage of Korean pine by the black-tipped sawfly, Acantholyda parki, has been increasing at several locations in central part of Korean peninsula. This study was undertaken at selected plots in Kapyung-gun, Kyunggi province, from 1998 to 1999. The purpose of study was to provide basic information for integrated control of this pest and to estimate the economic damage by analyzing the loss value of timber and seed reduction by attack of the sawfly. Volume growth was remarkably reduced when more than 50% of the needles were damaged, and reduction of total volume increment at the levels 70% , 90% and 100% of needle damage were 4.1㎥, 10.2㎥ and 18.7㎥ per hectare, respectively. One year old cone formation began to be reduced from 30% defoliation of the needles and few cones were produced in above 60% of defoliation. Also seed production started to be reduced from 50% defoliation of needles and the reduction rate at the level 70% of needle damage was 85% . The loss value of timber volume by damage of the black-tipped sawfly is estimated at 432,000 won per hectare at 70% of defoliation and above 1,000,000 won at 90%. The loss of seed is analyzed amounting to 100,000 won per hectare at less than 50% of it and at over 70% exceeding 2,000, 000 won. In case being damaged over 70% of defoliation by the black-tipped sawfly, the economic loss of timber and seed in total 30-year Korean pine forests of Korea would be estimated above 2 billion won and 10 billion won, respectively.

고도에 따른 제주 습지 수서곤충의 종풍부성 변화 : Rapoport 법칙의 검정

생물다양성(또는 종풍부성)에 미치는 고도 또는 위도 효과는 과거에서부터 현재까지 생물지리학자들의 최대관심사 중 하나라 할 수 있다. 본 연구는 제주도 한라산 24개 습지에 발생하는 수서곤충을 대상으로 고도구배에 따른 출현 종수(종풍부성)의 변화특성을 구명하고 Rapoport의 법칙을 검정하고자 실시하였다. 습지의 면적 효과를 제거하지 않았을 때 해발고도가 증가 할수록 수서곤충 출현 종수는 단조적으로(monotonical) 감소하였고 상관분석결과 통계적으로 유의한 역상관 관계를 보였다(r = -0.64). 고도와 출현 종수의 관계에서 출현 종수를 면적 대비 표준화하여 면적 효과를 제거한 결과 고도의 증가에 따라 처음에는 출현 종수가 증가하다가 최고점을 지나서는 감소하는 전형적인 고봉형 양상(hump-shaped pattern)을 나타냈다. 각 종의 평균 서식고도(수직분포의 중위값)와 수직서식분포 범위와의 관계는 평균 서식고도가 높을수록 분포범위가 증가하는 Rapport의 법칙을 따랐다. 노린재목을 제외하고 평균 서식고도와 수직분포 범위 간에는 정상관을 보였다(잠자리목: r = 0.75, 노린재목: r = -0.22, 딱정벌레목: r = 0.72, 전체: r = 0.55). 또한 상위영역 종은 평균 분포범위가 904.3m로 하위영역 종의 469.5m보다 통계적으로 유의하게 분포범위가 넓었다. 종합적으로 판단할 때 고도별 한라산 습지 수서곤충의 종풍부성 분포는 Rapoport의 법칙에 잘 일치되었다. The effect of altitude and latitude on biodiversity (or species richness) has been a topic of great interest for many biogeographers for a long time. This study was conducted to examine the dynamics of species richness of aquatic insects along the altitudinal gradient in 24 wetlands on Mt. Halla, Jeju and test the Rapoport's rule. The species richness of aquatic insects monotonically decreased with increasing altitude, showing a significant inverse correlation (r = -0.64). However, the pattern of species richness with altitude showed a hump-shaped relationship, with a peak in species richness at intermediate elevations when the effects of area were removed. The altitudinal range of species tended to increase with increasing altitude, as Rapoport's rule predicts. There was a positive correlation between the altitudinal range size and the midpoint of the range size (Median) except for Hemiptera (Odonata: r = 0.75, Hemiptera: r = -0.22, Coleoptera: r = 0.72, Total: r = 0.55). Also, the extent of average altitudinal range of high-altitude species was 904.3m, and it was significantly wider than a 469.5m of low-altitude species. Consequently, the species richness of aquatic insects in wetlands on Mt. Halla along the altitudinal gradient well supported Rapoport's rule.

The pine bark beetle. Tomicus piniperda, was studied by the biology of winter in central parts of Korea. The results obtained were as follows : 1. The adults penetrated into the bark of the stem and infiltrated into the cambium or near the cambium of coniferous species winter in the range of 5㎝ of underpart to 10㎝ of upperpart from ground level. 2. Before the adults penetrated into the bark into the bark in mid November, the temperature of stand during 5 days marked 10℃ less in maximum and 0℃ less in minimum. 3. When the overwintering adults escaped from the bark in mid to late March, the range of temperature was between 14 and 17℃ in maximum and 1 and 6℃ in minimum.

Artificial precipitation test with sprinkler system was carried out to develop the collection method of arboreal larvae(proctotrupoid wasps) of pine needle gall midge for biological control in 1995. Effects of larvae falling on each amount of precipitation, season of precipitation and time of precipitation of a day following artificial precipitation were examined during the period of larvae falling season. The results obtained were summarized as follows; 1. Artificial precipitation with sprinkler system was highly effective for collection of pine needle gall midge larvae and the most suitable amount of precipitation was 5.3-9.4mm; application amount and hours of water were 8,000-16.000ℓ and 180-360 minutes, respectively. 2. The most effective period of larvae collection for artificial precipitation was approximately 20 days, from early through mid November, and larvae falling was 93.4% of the total number of larvae collection during this period. 3. Larvae falling from the tree crown was not affected by the artificial precipitation for the precipitation hour intervals in a day. 4. The percentage of parasitism of collected larvae of pine needle gall midge in November exceeded that of December but was not significantly different between two seasons. 5. Artificial precipitation of sprinkler system was effective in reducing 34% of gall formation after one year at collected sites of pine needle gall midge larvae. 6. The collection method of larvae following artificial precipitation was effective in reducing the expenses by 14-50% than that of collection method of infested needles.
