Abstract:

Tateges erecta is an useful natural plant pesticide according to the former reports.In this paper,the effects on several enzyme systems about extracts of Tateges erecta against Tetranychus viennensis Zacher were studied.The results showed that the extracts of Tateges erecta had hgih effect on Tetranychus viennensis Zacher.Different from that of the dark treated group,the activities of protease,GSTs and esterase isozyme could be strongly inhibited in light treated group.The result indicated that the extract of Tateges erecta possessed high photo-activity.

Key words: Tateges erecta, Tetranychus viennensis Zacher, Protease, GSTs, Esterase isozyme
