【摘要】 本研究报道柑桔园5种常用杀菌剂,在田间使用浓度下,对柑桔红蜘蛛 Panonychus citri 生物学特性的影响.在25±1℃、相对湿度75±5%、光照周期14L:10D 的条件下,70%甲基托布津可湿性粉剂1500倍液、80%代森锌可湿性粉剂800倍液、50%多菌灵可湿性粉剂800倍液、20%叶青双可湿性粉剂800倍液和0.5%等量式波尔多液,对柑桔红蜘蛛各螨态历期、雌雄成螨寿命和雌成螨产卵量没有影响.仅70%甲基托布津1500倍液和50%多菌灵800倍液会降低柑桔红蜘蛛卵的孵化率,比对照卵孵化率91.0%分别减少了27.7%和24.3%.更多还原

【Abstract】 The present paper deals with effects of five fungicides on the biology of the citrus red mite, Panonychus citri(McGregor),under concentrations commonly applied in the fields.Thiophanatemethyl, zineb,carbendazim,ye-qing-shuang and bordeaux mixture did not affect the duration of any stage,longevi- ty of the female and male adults and fecundity of the citrus red mite under concentrations commonly applied in the fields.70% thiophanatemethyl 1500x and 50% carbendazim 800x reduced the hatchability.更多还原
