摘要
为掌握广西桑园常见害虫发生规律,评价不同防治措施对桑园主要害虫的控制效果,系统调查了桑园常见害虫种群动态及喷施杀虫剂、悬挂黄(蓝)板和安装杀虫灯等措施对桑园主要害虫虫口数量的影响。结果表明,桑园常见害虫约10种,优势种明显,主要为桑蓟马、朱砂叶螨、桑粉虱和桑螟,6—10月为害虫发生高峰期。单一物理防控措施对桑园主要害虫控制效果最差,化学和物理组合防控措施40%灭多威乳油6 000倍液+60%敌畏·马乳油2 000倍液+10%蚜虱净可湿性粉剂4 000倍液+黄板0.1块/m^2和73%炔螨特乳油3 000倍液+8%残杀威可湿性粉剂2 000倍液+60%敌畏·马乳油2 000倍液+蓝板0.1块/m^2+杀虫灯0.5盏/hm^2的控制效果较好,处理后1 d防效接近或超过70%,处理后10 d防效在80%以上。上述2种综合防控措施对桑园桑蓟马、朱砂叶螨、桑粉虱和桑螟等主要害虫防控效果好,可为桑园虫害综合防控提供参考。
To master the occurrence regularity of common pests and evaluate the control effect of different control measures on major pests in mulberry field in Guangxi Zhuang Autonomous Region,a systematic survey on the number of common pests was conducted,and the effects of spraying insecticides,hanging yellow and blue sticky cards,installing insecticidal lamps and other measures on the number of the above major pests on mulberry were detected.The results showed that the common pests in mulberry field belonged to about 10 species,the dominant species were obvious,which were Pseudodendrothrips mori,Tetranychus cinnabarinus,Pealius mori and Diaphania pyloalis,and the peak of the major pests was from June to October.The control effect of single physical measure on the main pests was the worst in mulberry field.The control effects of combinations of physical and chemical measures,40% methomyl EC( 1 ∶ 6 000) + 60%dichlorvos malathion EC( 1 ∶ 2 000) + 10% imidacloprid WP( 1 ∶ 4 000) + 0.1 yellow sticky card per square meter and 73% propargite EC( 1 ∶ 3 000) + 8% propoxur WP( 1 ∶ 2 000) + 60% dichlorvos malathion EC( 1∶ 2 000) + 0.1 blue sticky card per square meter + 0.5 insecticidal lamp per hectare,on the four main pests in mulberry field were better.The control effects of the two measures on the fourmain pests were close to or higher than 70% one day after treatment,and were higher than 80% ten days after treatment.The above two integrated control measures had better control effects against Ps.mori,T.cinnabarinus,Pe.mori and D.pyloalis,and could provide reference for the integrated management of pests in mulberry field.
