Maps of COI gene restriction enzyme of the four species of pests were obtained. Moreover, three restriction enzymes were selected to cut the amplified COI gene fragments of X. rusticus, C. lapathi, and A. glabripennis specifically, but the COI gene of S. populnea could not be cut by any of these three restriction enzymes. Therefore, the assistant method could be applied to the inspection and quarantine of these kinds of pests, based on the primary identification of pests by their morphological characters and damage features, which would improve the identification accuracy.},

	abstract = {Tomicus 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.},

	abstract = {An experiment was conducted to study the chaotic characteristics of population size of adult boring insects in Pinus massoniana forests based on chaos theory using power spectrum analysis, correlation dimension, the largest Lyapunov exponent and the principal component method. Results show that the sequence of adult population of boring insects in P. massoniana forests has chaotic characteristics, belonging to chaotic time series. Attractors exist in the reconstructed multi-dimensional phase space, and also exhibit fractal dimension characteristics. If the delay time [TAU] is 3, the embedding dimension m is 17, then the correlation dimension D is 3. 191 7 in related phase dimension and the largest Lyapunov exponent o is 0.308 9. Therefore, the population size of adult boring insects in P. massoniana forests could be forecasted by reconstructed phase space method according to the chaotic characteristics of one-dimensional time series.},

Results show that the stem borer attractant has a wide trapping spectrum of 42 species of insects in 16 families which damage stem, branch and leaf of P. massoniana, including Monochamus alternates Flope, Spondylis buprestoides Linnaeus, and Shirahoshizo patruelis Voss. which could carry Bursaphelenchus xylophilus as well as two species of natural enemies in two families. Cerambycidae, Scolytidae, and Curculionidae are dominant populations of stem borers, among which 12 species be-long to Cerambycidae. The dominant trapped species are Shirahoshizo erectus Chen, Cryphalus massonianus Tsai et Li, and S. buprestoides. Stem borer attractant could continuously monitor the occurrence time, occurrence amount, and occurrence regularity of adult M. alternates, S. buprestoides, S. patruelis, S. erectus, and Hyposipalus gigas Linnaeus. Continuously applying the attractant could decrease population density of stem borers significantly, and provide a direct and objective basis for monitoring, forecasting and controlling main stem borers in pine trees.},

Results showed that the combination of Ipsdienol (Id), E-myrcenol (EM), and Amitinol (At) at a dose of 20 mg for each component exhibited the highest trapping efficiency for the bark beetles, while Id combined with EM at a high dose (200 mg for each component) displayed the best trapping efficiency. The trapping effect of the open plastic vial lure was the best among three different dispenser types. In monitoring and mass-trapping, the optimum dose for the combination of Id, EM, and At for the dispenser of plastic bag with sponge was 20 mg for each component and the ratio was 1: 1: 0. 1.},
