摘要
通过对桃小食心虫的大量饲养和观察及性激素诱扑器在实际中的应用。完成了性激素诱蛾配合期距法的桃小食心虫测报新技术研究,得出在其成虫发生高峰后3—7天用药,可获得最佳防治效果的结论,并指出第一代用药一次,第二代用药两次,就完全能控制桃小食心虫的全年为害。试验还同时进行了多种农药防治桃小食心虫的测定。
We finished the new techniqual study of forecast Carposina niponensis Walsingham with sew hormone luring and time isolation by raising and observing a large number of C. niponensis Walsingham as well as applying sex hormone moth-killing in practice. We obtained the result that using pesticide after three to seven days of adult happening peak could get the best prevention and control effectiveness. Using pesticide one time in the first generation and two times in the second generation could wholely control the yearly harming of C. niponensis Walsingham.
