性引诱剂防治桃园桃小食心虫试验

桃小食心虫是我国北部、中部果区的主要害虫,其危害严重影响果实的品质和产量。试验通过在桃园中放置桃小食心虫性诱剂,每天观察记录桃小食心虫的数量,7、8月份调查试验地和对照地的虫果率。结果表明,2004年蛾发生期为6月20日到8月29日,共诱蛾732头,试验地和对照地的虫果率无明显差别,说明利用桃小食心虫性诱剂可有效地对桃小食心虫进行预报和防治,减少果园中农药的用量,达到了提高产量和果实品质的目的,同时总结了桃小食心虫在太谷地区的发生和消长规律。

Experiment of Lure to Prevent and Control Carposina Niponensis

Carposina niponensis is a major pest in orchards of north and middle China, its harm influencing the quality and yield of fruit seriously. We observed and noted the number of carposina niponensis every day, investigating rate of infected fruit of test and control field in July and August by putting lure in the peach orchards . The results showed that moth occured from 20th of June to 29th of August, luring 732 moths in 2004, rate of infected fruit of test and control field being no significant difference. So we can forecast and controlcarposina niponensis efficiently by lure, decreasing the quantity of pesticide in the orchards and improving the output and character of fruit. We summarized carposina niponensis occurrence and change rules on Taigu.
