摘要
暗黑赤眼蜂是鳞翅目害虫的卵寄生性天敌,明确其对番茄潜叶蛾的寄生能力,为暗黑赤眼蜂田间防控番茄潜叶蛾提供研究基础。本文通过设置不同水平的番茄潜叶蛾卵密度、温度、湿度、有无光照及番茄潜叶蛾卵的产出天数,评价影响暗黑赤眼蜂寄生番茄潜叶蛾卵的主要因素。暗黑赤眼蜂单雌在寄生卵密度为30粒卵/管,温度26℃、相对湿度75%、黑暗条件下的寄生率最高,可达93.33%。番茄潜叶蛾卵的产出时间越长,暗黑赤眼蜂对其寄生能力越弱。根据拟合结果表明,暗黑赤眼蜂对番茄潜叶蛾卵的寄生与Holling-Ⅱ型功能反应的圆盘方程相符,说明暗黑赤眼蜂是防治番茄潜叶蛾的潜在寄生蜂之一。
Trichogramma pintoi is an egg-parasitic natural enemy of Lepidopteran pests.Clearify its ability to parastic eggs of Phthorimaea absoluta provides a sight for controling P.absoluta by T.pintoi in field.In this paper,by setting different levels of egg density of T.absoluta,temperature,humidity,presence or absence of light and the days after egg laid,the main factors that affect T.pintoi parasitizing P.absoluta eggs are evaluated.At the parasitic egg density of 30 eggs/tube,26℃,75%relative humidity,and darkness environment,the parasitic rate is the highest and reach to 93.33%.The longer the duration of egg laid by P.absoluta is,the weaker the ability of T.pintoi to parasitize it.According to the model fitting test,the parasitism of T.pintoi on P.absoluta eggs is consistent with the disc equation of Holling-Ⅱfunctional response,indicating that T.pintoi is one of the potential parasitoids to control P.absoluta.
