(Scots pine) in Poland. Additionally, fungal succession in P. sylvestris sapwood was investigated during a 12aweek period following an attack by this insect. Fungi were isolated from five populations of overwintered adult beetles and their galleries with 59 species of fungi being represented among the 2880 cultures obtained. The most frequent species, Ophiostoma canum (Munch) Syd. & P. Syd., Hormonema dematioides Lagerb. & Melin, and Ambrosiella tingens (Lagerb. & Melin) L.R. Batra, appeared to be specifically associated with T. minor. The succesional changes in species composition during a 12aweek period following an attack by T. minor were observed. The pattern of fungal succession in P. sylvestris sapwood essentially agreed with a general scheme of fungal succession in tree sapwood infested by bark beetles. Ambrosiella tingens was the first invader of sapwood and occurred most frequently in its deeper layers. Ophiostoma canum, H. dematioides, and other molds were also often isolated from the sapwood; however, they were most common at a depth of 5amm during the initial phase of fungal colonization. Later, Ophiostoma canum followed A. tingens in the sapwood invasion.10aTomicus minor1 aJankowiak, Robert  uhttps://weevil.myspecies.info/fungi-associated-tomicus-minor-pinus-sylvestris-poland-and-their-succession-sapwood-beetle-infested01606nas a2200205   4500008004100000020001400041245008000055210006900135260001100204300001000215490000700225520096500232653001801197653002401215100001601239700001601255700001601271700001201287856010101299       2012                        eng d  a1000-538200aShoot feeding by Tomicus (Coleoptera: Scolytinae) on Pinus yunnaensis trees0 aShoot feeding by Tomicus Coleoptera Scolytinae on Pinus yunnaens  cJun 25  a81-840 v403 aTomicus minor and Tomicus yunnanensis are two important pine shoot beetles on Yunnan pine (Pinus yunnanensis Franchet) in Yunnan Province. Shoot feeding and trunk attack are two factors of tree death. The current studies were conducted under field conditions that the beetles were allowed to attack the shoots. Factors influencing shoot feeding by T. minor and T. yunnanensis were discussed. Result shows that there is a remarkable relationship between gallery length and shoot length, and this correlation is also noticeable between gallery length and shoot diameter. Positions of invading holes on the shoots (lower, middle, or upper) attacked by Tomicus determine the gallery length to a great extent, and there is a significant relationship between them. The main influence factors on shoot feeding by T. minor are positions of invading holes, while those on shoot feeding by T. yunnanensis are shoot length, shoot diameter and positions of invading holes.10aTomicus minor10aTomicus yunnanensis1 aGao, Yanfei1 aZhang, Ying1 aZhang, Zhen1 aWu, Wei  uhttps://weevil.myspecies.info/shoot-feeding-tomicus-coleoptera-scolytinae-pinus-yunnaensis-trees01593nas a2200181   4500008004100000020002500041245014600066210006900212260000900281300000800290490000900298520097400307653001801281653002401299100001401323700001801337856005601355       2012                        eng d  a0033-2615; 1687-743800aPerformance of Tomicus yunnanensis and Tomicus minor (Col., Scolytinae) on Pinus yunnanensis and Pinus armandii in Yunnan, Southwestern China0 aPerformance of Tomicus yunnanensis and Tomicus minor Col Scolyti  c2012  a1-60 v20123 aPine shoot beetles, Tomicus yunnanensis Kirkendall and Faccoli and Tomi cus minor Hartig (Col., Scolytinae), have been causing substantial mortality to Yunnan pine (Pinus yunnanensis Franch) in Yunnan, southwestern China, whereas only a few Armand pine (Pinus armandii Franch) were attacked by the beetles. In order to evaluate the suitability of P. armandii as host material for the two Tomi cus, adults of both Tomi cus were caged on living branches and felled logs of the two pines during shoot feeding and trunk attack phase, respectively. More beetles survived on the living branches of P. yunnanensis than on P. armandii. Tomi cus yunnanensis and T. minor produced similar progeny in the logs of the two pines. The sex ratio and developmental period were not affected by host species, but the brood beetles emerging from Armand pine weighed less than those from Yunnan pine, suggesting that P. armandii are less suitable to be host of T. yunnanensis and T. minor.10aTomicus minor10aTomicus yunnanensis1 aZhao, Tao1 aLangstrom, Bo  uhttp://www.hindawi.com/journals/psyche/2012/363767/01910nas a2200241   4500008004100000020002500041245011300066210006900179260000900248300000900257490000900266520116700275653001801442653002401460100001901484700001801503700001601521700002001537700001701557700001901574700001901593856005601612       2012                        eng d  a0033-2615; 1687-743800aCoexistence and Competition between Tomicus yunnanensis and T. minor (Coleoptera: Scolytinae) in Yunnan Pine0 aCoexistence and Competition between Tomicus yunnanensis and T mi  c2012  a6pp.0 v20123 aCompetition and cooperation between bark beetles, Tomicus yunnanensis Kirkendall and Faccoli and Tomicus minor (Hartig) (Coleoptera: Scolytinae) were examined when they coexisted together in living Yunnan pine trees (Pinus yunnanensis Franchet) in Yunnan province in Southwest China. T. yunnanensis bark beetles were observed to initiate dispersal from pine shoots to trunks in November, while the majority of T. minor begins to transfer in December. T. yunnanensis mainly attacks the top and middle parts of the trunk, whereas T. minor mainly resides in the lower and middle parts of the trunk. The patterns of attack densities of these two species were similar, but with T. yunnanensis colonizing the upper section of the trunk and T. minor the lower trunk. The highest attack density of T. Yunnanensis was 297 egg galleries/m2, and the highest attack density of T. minor was 305 egg galleries/m2 . Although there was significant overlap for the same bark areas, the two species generally colonize different areas of the tree, which reduces the intensity of competition for the relatively thin layer of phloem-cambium tissues where the beetles feed and reside.10aTomicus minor10aTomicus yunnanensis1 aLu, Rong, Chun1 aWang, Hongbin1 aZhang, Zhen1 aByers, John, A.1 aJin, You, Ju1 aWen, Hai, Feng1 aShi, Wen, Jian  uhttp://www.hindawi.com/journals/psyche/2012/185312/
