Cellulase in Anoplophora glabripennis adults emerging from different host tree species
Cellulase in Anoplophora glabripennis adults emerging from different host tree species
摘要
Abstract
In order to investigate different kinds of cellulase in insect pests, we selected male and female adults of Anoplophora glabripennis (Motschulsky) emerging from four different host species (Populus alba vat. pyramidalis, P. nigra vat. thevestina (Dode)Bean., P. simonii × P. pyramidliscr cv. Opera 8277 Hsu. and Salix matsudana f. lobato-glandulosa) as our research material. The enzyme activitives of three kinds of cellulase in the intestines of the adult insects were measured. The Cx-cellulase isozymes were detected with a CMC-incorporated polyacrylamide gel. The results show that: there are no statistically significant differences between the enzyme activities of males and females emerging from the different host species. The order of magnitude in activity is:Cx-cellulase ＞β-glycosidase ＞ C1-cellulase. When the adults emerge from the same host species, there are no statistically significant differences between male and female enzyme activities ofβ-glycosidase and C1-cellulase, but the enzyme activity of Cx-cellulase of males is clearly higher than that of females. The patterns and migration of Cx-cellulase isozymes of males and females emerging from different hosts trees are clearly not different, and neither are they different when emerging from the same hosts.关键词
