Abstract:

During the adult Monochamus alternatus taking food for supplementary nutrition,the mixture of 18% dimilin Ⅲ micro-capsule(80%) and other kinds of pesticide micro-capsu1(20%) was sprayed to control them.The results showed that the controlling effect is significant,with the mixture of micro-capsuls of dimilin Ⅲ and of Angaosha IV spraying showing the best effect.The direct effect and the persistent effect of 10,20,30 days after spraying reached 100%.The mixture of micro-capsuls of dimilin Ⅲ and of Angaosha I,and that of dimilin Ⅲ and Angaosha Ⅲ also showed better effect,but their persistent effect of 30 days after sprying decrease by some extent,and that of dimilin Ⅲ and Angaosha Ⅱ behave relatively poor.However pure dimilin Ⅲ micro-capsule showed poorer effect than all its mixture.
