不同杀菌剂对柑桔红蜘蛛生物学特性的影响

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 cltrl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％多苗灵可湿性粉剂800倍液．20％叶青双可湿性粉剂800倍液和0．5％等量式渡尔多液。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％．

EFFECTS OF FUNGICIDES ON THE BIOLOGY OF THE CITRUS RED MITE,PANONYCHUS CITRI(MCGREGOR)

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.
