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-trees01716nas a2200181   4500008004100000020001400041245015700055210006900212260000800281300001200289490000700301520101900308100001701327700001601344700002001360700001901380856013501399       2010                        eng d  a0968-432800aAntennal morphology and sensilla ultrastructure of Dendroctonus valens LeConte (Coleoptera: Curculionidae, Seolytinae), an invasive forest pest in China0 aAntennal morphology and sensilla ultrastructure of Dendroctonus   cOct  a735-7410 v413 aDendroctonus valens Leconte, an invasive forest pest, is highly dependent on its olfactory system for activities such as host seeking, mating, oviposition and population aggregation. The antennae are the primary olfactory organs in bark beetles. We describe four morphological types of sensilla on the antenna of D. valens: (1)3 subtypes of sensilla trichodea located at the apex and lateral surface of the club. Sensilla trichodea types 1 and 3 were innervated by 5 and 13 dendrites, respectively. Sensilla trichode type 2 was not found dendrites in a lumen, (2) sensilla chaetica found on the scape and funicle and innervated by 7 dendrites, (3) a pair of sensilla basiconica distributed primarily on the three sensory bands, each innervated by 2 dendrites at the base, and (4) one fluted cone type of grooved peg dispersed throughout the sensory bands. The possible functions of these sensilla are discussed in relation to their morphology and ultrastructure. [copyright] 2010 Elsevier Ltd.

One of predator species of RTB (Prostomis sp.) was found in the larval gallery. Behavioral response of this natural enemy to the volatiles emitted from healthy pines ( Pinus tabulaeformis) RTB damaged pines and fecal pellets of RTB were studied with a Y-tube olfactometer. The results showed that natural enemies were attracted to all the volatiles above, especially to that of damaged pines. Volatiles from healthy pines, RTB damaged pines and fecal pellets of RTB could be used by the natural enemies to locate the host habitat and to discriminate the pines damaged from healthy ones. The predator species of RTB (Prostomis sp.) was more sensitive to (S) - ( +) -3 -Carene than three other monoterpenes in the lab. experiment.10aDendroctonus valens1 aZhang, Yong-jie1 aZhang, Pei-yi1 aLiu, Jun1 aJin, You-jiu1 aZhang, Zhen  uhttps://weevil.myspecies.info/effect-volatiles-dendroctonus-valens-and-pinus-tabulaeformis-behavioral-selection-natural-enemy01408nas a2200157   4500008004100000020001400041245005200055210004900107260000900156300001200165490000700177520095700184100001701141700001601158856007601174       2010                        eng d  a0030-531600aAN INVESTIGATION IN ACOUSTIC INSECT RECOGNITION0 aINVESTIGATION IN ACOUSTIC INSECT RECOGNITION  c2010  a415-4280 v443 aThis study aims to provide general technicians who manage pests in production with a convenient way to recognize insects. Several viable schemes to identify insect sounds automatically are introduced using sound parameter standardization techniques that dominate speaker recognition technology. The acoustic signal is preprocessed, segmented into a series of sound samples. Mel-frequency cepstrum coefficient (MFCC) and Sub-band based cepstral (SBC) are extracted, respectively from the sound samples, and Vector Quantization(VQ) codebook and Hidden Markov Model(HMM) are trained with given features. The matching for a test sample is completed by finding the nearest neighbour in all the VQ codebooks or the best matcher in all HMMs. These methods are evaluated and compared in a database with acoustic samples of 70 different insect sounds. The MFCC and HMM based methods demonstrated their better performance, whose recognition accuracy exceeds 98%.1 aZhu, Le-Qing1 aZhang, Zhen  uhttps://weevil.myspecies.info/investigation-acoustic-insect-recognition01910nas 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/2012/185312/01578nas a2200217   4500008004100000020002500041245009500066210006900161260001100230300001000241490000900251520093500260653002101195100001201216700001601228700001801244700001201262700001401274700001701288856005501305       2010                        eng d  a1175-5326; 1175-533400aTomicus armandii Li & Zhang (Curculionidae, Scolytinae), a new pine shoot borer from China0 aTomicus armandii Li Zhang Curculionidae Scolytinae a new pine sh  c20 Aug  a57-640 v25723 aWe describe a new species of forest bark beetle, Tomicus armandii Li & Zhang, collected from Pinus armandii in Yunnan, China. We used the D2 fragment of 28S rDNA to improve the taxonomy of Tomicus. The new species can easily be distinguished from the other Tomicus species using the following two morphological characters: punctures of interstria 2 on declivity appearing evenly biseriate or triseriate; erect interstrial setae on the declivity short, about 0.5x as long as distance between striae. The genetic distances of 28S rDNA measured between T. armandii and other species of Tomicus are similar to the distances between other Tomicus species, and these are much higher than intraspecific distances. The phylogenetic analysis of 28S rDNA agrees with the groupings obtained from morphological identification. DNA analysis has commonly been used in Tomicus taxonomy and is helpful for resolving taxon identification problems.10aTomicus armandii1 aLi, Xia1 aZhang, Zhen1 aWang, Hongbin1 aWu, Wei1 aCao, Peng1 aZhang, Peiyi  uhttp://www.mapress.com/zootaxa/list/2010/2572.html
