摘要
芒果芽瘿螨,在中国为新记录,是危害我国芒果树芽部的新害螨。据1986—1987年在海南调查,嫩芽最高受害率达87.5％。室温26—32℃下饲养从卵到成螨出现历期13—17天,其中卵期平均5.5天,若螨期平均9.5天。螨的数量在2月下旬至5月上旬最少的,5月中旬开始增加,6月上旬至7月上旬为第一发生高峰期,9月下旬至10月上旬为第二高峰期。室内试验结果,用50％硫磺胶悬剂400倍液进行防治,效果良好。
Eriophyes mangiferae(Sayed) is a new record of Eriophyoidea from China. It is widely distributed in mango growing areas in South China. The mite causes necrosis of infested bud scales of mango (Mangiferae indica) with the maximum damage rate at 87.5%. The total duration for the development of the mite from egg to adult was 13-17 days under room temperature at 26-32℃. Its egg stage and nymph stage averaged 5.5 days and 9.5 days respectively. Sharp decline in its population occurred in late February to early May. The population began to increase in mid May and reached their peak during June to early July and late September to early October, The mite could be controlled by spraying mango tree with 0.125% sulfur suspensoid.
