	abstract = {The aim of this study is to identify the semiochemicals of the female weevil, Cyrtotrachelus buqueti Guerin-Meneville, an important bamboo forest weevil pest in Southern China. The behavioral responses of male weevils to the crude cuticular extracts from virgin female weevils in a flight tunnel was analyzed, and the results showed that male weevils had positive response to the cuticular extracts as well as to virgin female weevils. The sensitive reaction of male weevil{\textquoteright} s antenna to the crude cuticular extracts from virgin female weevils was detected by GC-EAD, and the components of the cuticular extracts that consistently elicited antennal responses were identified by GC-MS. The results indicated that male weevil{\textquoteright} s antenna had sensitive reaction to synthetic standard chemicals of five components in the female extracts, i. e., phenol, ethyl hexanoate, 2-nonanone, nonanal, and pentadecanoic acid methyl ester. Flight tunnel and GC-EAD studies showed that the five synthetic chemicals were also bioactive to male weevils, suggesting that phenol, ethyl hexanoate, 2-nonanone, nonanal, and pentadecanoic acid methyl ester are semiochemicals of C. buqueti.},

	abstract = {The invasive red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier), native to Southern Asia, is becoming a serious invasive pest of palms in China. In order to understand how well the RPW survives under cold temperature, with materials from fields in Shanghai we determined the supercooling points (SCPs) with supercooling point determinator and the degree of cold hardiness in environmental chamber at low temperatures, simulated field overwintering test in Shanghai, and analyzed the north limit for overwintering of RPW. The results indicated that SCPs of the RPW were significantly decreased as the developmental stages increased. Adults had the lowest SCPs, followed by 9th, 5th and 1st instar larvae and eggs in an increasing order. The viability of various developmental stages in the RPW was measured in 6, 24, 48 and 72 h, and the relationship between the survival rate and low temperature could be fitted with logistic model significantly or extremely significantly. Ltemp50(the temperature that results in 50\% mortality of the experimental population) was increased as time prolonged at all stages of the RPW. At 72 h after treatment, Ltemp50 values of eggs, 1st instar larvae, 5th instar larvae, 9th instar larvae and adults were 1. 61, -1.67, -2.39, -2.40 and -0.40[degree]C, respectively. This result showed that the larvae had the highest cold hardiness, followed by adults and eggs in order. The above data indicated that the correlation between the cold hardiness and SCPs was not uniformly positive. Thus, we speculated that either adult or larva could be possible stage of overwintering for the RPW. The field ovenvintering test also showed that survival rates of both larvae and adults were above 60\% in continuous two years ( 2007 and 2008), suggesting that the RPW could overwinter in the field in Shanghai. Based on the results obtained and distribution of the hosts of the RPW, we tentatively inferred that the northern limit for overwintering of the RPW is proximate to 35[degree]N or where the average low temperature in January is around 0[degree]C.},

	abstract = {(Aims) Behavioural responses of adults of Nassophasis sp., a species infesting medicinal herb Dendrobium thyrsiflorum, to different odor sources were studied to explore new control methods towards this pest. (Methods) Behavioural responses of Nassophasis sp. adults to different odor sources including conspecifics, puparium, frass, and damaged stem of host plant, Dendrobium thyrsiflorum, were tested with pitfall olfactometer. (Results) The results indicated that odor emitted from females could only attract males but not females. The odor from males was not attractive to both sexes. Both sexes could be significantly attracted to puparium. Neither female-produced frass nor male-produced frass showed significant attraction to both sexes. When females and males aggregated, however, their frass demonstrated significant attraction to both sexes. Female adults only responded to female-damaged stem, while male adults only to male-damaged stem. (Conclusion) These preliminary results may serve as basis to isolate and identify the attractive compounds from these odor sources.},
