지금까지 한국의 긴나무좀아과에는 4속 6종이 알려져 있다. 본 연구에서는 3종의 한국 미기록종을 다음과 같이 보고한다: 배외긴뿔나무좀 (Crossotarsus niponicus (Blandford, 1894)), 이승악긴나무좀(Platypus contaminatus (Blandford, 1894)), 닮은긴나무좀(Platypus quercivorus (Murayama, 1925)).

The diurnal flight pattern of Platypus koryoensis (Murayama) was examined using sticky traps attached to the trunks of oak trees in central Korea in 2011. The flight activities of the beetle were estimated on the basis of 2-h interval trap catches from 05:00 to 17:00, between June 9 and July 21 (the peak flight period of the beetle). Peak flight time of the beetle ranged from 09:00 to 13:00, with variations due to the day surveyed and the facing slope. The flights began when the air temperature reached 16.7 °C, and the flights peaked when the air temperature was 23.6 °C. Flights were not observed during rainfall, suggesting that rainfall is one of the factors that influence beetle flight. The time of sunrise was not significantly correlated with the flight initiation time. The direction of flight along with the slope was changed bidirectional to unidirectional (movement from upslope to downslope) between 9:00 and 13:00.

 ,  , This study was conducted to elucidate the patterns of occurrence of bark beetles on deadwoods of Quercus serrata Fisher and Carpinus laxiflora Blume which are expected to increase due to climate change. The survey was carried out at the LTER site in Gwangneung forest in Gyeonggi Province in 2007-2008. Bark beetles were collected using emergence traps and attraction traps (funnel trap and window trap). A total of 408 beetles belonging to 12 species in two subfamilies were collected. Platypus koryoensis (Murayama) was the most abundant species. P. koryoensis and Xylosandrus germanus (Blandford) occurred mainly in deadwoods of Q. serrata. All other species, except two rare species, occurred commonly in deadwood of both tree species. Species richness and abundance of bark beetles were higher in the attraction traps than in the emergence traps, and higher in Q. serrata than in C. laxiflora. These indexes were higher in classes Ⅰ-Ⅱ or Ⅰ-Ⅲ than in classes Ⅲ-Ⅳ or Ⅳ of deadwood. Bark beetle communities differed according to years and showed a little difference between tree species.

An ambrosia beetle, Platypus koryoensis, is a vector of Raffaelea quercimongolicae that is known to cause Korean Oak Wilt (KOW), one of the serious threats to forest healthy in Korea. To manage P. koryoensis properly, it is necessary to clarify flight period of the adult. This experiment was conducted to elucidate the relationship between temperature and the flight period based on field observation in three forests consisted of Quercus mongolica from 2007 to 2009 except winter season. Date of flight period for 50% (FP50) was estimated by the cumulative Weibull distribution model based on cumulative proportion of the adult density and air temperature. Relationship between site temperature and the date of FP50 of P. koryoensis was the most significant when temperatures below 6.5℃ were excluded, suggesting lower threshold temperature for the flight period based on the site temperature. The pooling cumulative proportion of flight period against degree days was well described by the degree-day model, which has explanatory power for the 89% of year and site variation in the flight period and predicted accurately the flight pattern in 2011.
