桃小食心虫在小枣上的危害调查与控制

Hazard Investigation and Control of Carposina niponensis Walsingham on Jujube

小枣在滨州市普遍种植,在滨州市主产区普查中发现,小枣膨大期之后,蛀果率较高,受害严重的园区可达100%,导致枣果提前脱落,经鉴定为桃小食心虫为害。近年来,桃小食心虫在小枣上危害较重,本文对桃小食心虫的发生现状进行了调查,分析了其转移到小枣寄主上为害的原因,并提出了科学的预测预报方法及优先采用农业、生物、物理方法,辅以化学防治的绿色综合防控对策。

Jujube is widely planted in Binzhou city.In the general survey of the main jujube producing areas in Binzhou city,it was found that after the expansion period of jujube,the fruit decay rate was high,and the seriously affected parks could reach 100%,resulting in the early falling off of jujube fruit,which was identified as the damage of C.niponensis Walsingham.In recent years,the C.niponensis Walsingham did more harm to jujube.This paper investigated the current situation of occurrence,analyzed the reasons for its damage when it was transferred to jujube,put forward the scientific prediction and forecast method,and gave priority of green comprehensive prevention and control countermeasures gave priority to agricultural,biological and physical prevention and control methods supplemented by chemical prevention and control.
