Anoplophora glabripennis Motschulsky, a wood borer native to Asia, was recently found in New York City and Chicago. In an attempt to eradicate these beetle populations, thousands of infested city trees have been removed. Field data from nine U.S. cities and national tree cover data were used to estimate the potential effects of A. glabripennis on urban resources through time. For the cities analyzed, the potential tree resources at risk to A. glabripennis attack based on host preferences, ranges from 12 to 61% of the city tree population, with an estimated value of $72 million-$2.3 billion per city. The corresponding canopy cover loss that would occur if all preferred host trees were killed ranges from 13- 68%. The estimated maximum potential national urban impact of A. glabripennis is a loss of 34.9% of total canopy cover, 30.3% tree mortality (1.2 billion trees) and value loss of $669 billion.

Two recent exotic tree insects introduced into North America are the pine shoot beetle, Tomicus piniperda, and the Asian longhorned beetle, Anoplophora glabripennis. These two insects are just recent additions to the more than 4500 exotic organisms now established in the United States.

The major proteinase activities in the larval midgut of a common poplar tree borer, Anoplophora glabripennis, were characterised. Overall digestive capacity, as measured by casein hydrolysis, showed a pH optimum between 10 and 11.5, suggestive of serine endopeptidase activity. Trypsin, chymotrypsin, and chymotrypsin-like activities were detected using specific p-nitroanilide synthetic substrates and by use of specific serine endopeptidase inhibitors. These activities also showed pH optima in the extreme alkaline range. The absence of cysteine, aspartic, and metallo-endopeptidases were confirmed using class specific proteinase inhibitors. The dominant exopeptidase in the midgut is leucine aminopeptidase with a pH optimum of 7-9. Carboxypeptidase a and b activity were barely detectable. A large range of serine endopeptidase inhibitors were screened and were found to vary widely in their ability to inhibit casein hydrolysis. Potato proteinase inhibitor 1 (a chymotrypsin inhibitor) and wheat-germ trypsin inhibitor 1 inhibited particularly effectively in tandem and represent possible candidates for gene transformation to produce plants tolerant to this pest.

In this papar, 42 male specimens of A. nobilis and A. glabripennis, from different districts for OTU were studied by means of numerical taxonomic methods. Among 27 characters, sixteen are quantitative and eleven are qualitative. The principal component analysis and the similarity coefficients were computed on the standardized data. Based on the square of mean Euclidian distance matrix, mean Euclidian distance matrix and the correlation matrix respectively, the Q cluster analysis was also performed. UPGMA was used in both Q and R cluster analysis. Fuzzy clustering method was used too. The dendrograms of each Q clustering method are similar. All OTU was divided into 5 groups. From the results of the R cluster analysis, all characters could divided into 4 sets: A, B, C and D, and the PCA were shown no difference with those of Q cluster analysis. A. nobilis and A. glabripennis distributed in Northwest and North China and propealed great difference in the phenograms and in the characters of the male adults, of the male genitalia and of the larval. Thus, the author inclined to support the view of dividing them into two independent species. Taxonomic rank level of species was 1.75, 1.38, 0.15 and 0.77 respectively. Comparing with the typical specimen of A. glabripennis from North China, those from Sichuan Province showned degree of dissimilarity to species rank level. They were considered to be a new species.

The strain TW20 was isolated from a soil sample collected in Beijing. Morphological observation showed that the vegetative cell was not motile. Gram-positive. Rod with dimensions of 1.2--1.5 x 4.0--5.0 mu m. Parasporal inclusion is irregular in shape. Bioassays on larva have shown that the new strain TW20 has no pathogenicity against Dendrolimus tabulaeformis, Lymantria dispar, Malacosoma neustria testacea and Anoplophora glabripennis . On the basis of the aforementioned, the authors propose the name of Bacillus thuringiensis subsp. wenguanensis for the type strain TW20.

This paper describes the relationship of absorbing nourishment between woodpecker (Dendrocopos major cabanisi ) and longicorn (Anoplophora glabripennis ). Woodpecker pecks the elder larvas and chrysalises of longicorn in winter and spring, and longicorn develops and breeds in summer and autumn to maintain the lasting of its population. Such a fixed relationship of absorbing nourishment is a phenomenon of coevolution.
