桃小食心虫Carposina niponen-sis Wals·(以下简称桃小)属鳞翅目、蛀果蛾科。是乐陵枣区历年危害枣果的一大害虫,蛀果率一般年份为15—20％,严重时达50％以上。由于越冬幼虫出土期长,且受降雨情况的影响很大,在生产中如何确定经济有效的防治适期,是防治上必须解决的一个实际问题。为此,我们在1982—1987年利用性诱剂诱蛾,观察蛾量消长规律,以期达到预剂防适期的目的。 Carposina niponen-sis Wals · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · Luling jujube is harmful to jujube fruit pests over the years, bore fruit rate of 15-20% of the general year, severe up to 50% or more. Due to the long period of overwintering larvae excavated and the great influence of rainfall, it is a practical problem that must be solved in the prevention and control of how to determine the economic and effective control period in production. To this end, we use sex attractant moth in 1982-1987, to observe the law of moth growth and decline, in order to achieve the purpose of pre-dose anti-fit.
