近年来,瘿螨在广西百色市杧果产区局部果园发生为害严重。开展广西杧果瘿螨发生为害调查与防治药剂筛选研究,结果表明:广西为害杧果的瘿螨共有4种,分别为杧果顶背瘿螨Tegonotus mangiferae Keifer、杧果臀后瘿螨Metaculus mangiferae Attiah(中国新记录种)、杧果刺毛瘿螨Spinacus pagonis Keifer(广西新记录种)、长刺毛瘿螨Spinacus longinquus Huang(广西新记录种)。杧果顶背瘿螨是广西杧果瘿螨的优势种,27℃时其世代历期11.34 d。杧果瘿螨在叶片上的种群密度最高可达47头/cm2,为害严重时可导致杧果枝梢叶片脱落。15%哒螨灵EC 2500倍液、40%炔螨特EC 1500倍液、20%呋虫胺SG 2000倍液对芒果瘿螨卵的触杀死亡率在86%以上,对成螨的触杀死亡率在91.0%以上。常用的杀螨剂和一些杀虫剂对杧果瘿螨有很好的防治效果。
In recent years, scabies mites in Baise City, Guangxi fruit orchards occurred in the orchard serious damage. The results showed that there were 4 kinds of Scabies mites in Guangxi, which were Tegonotus mangiferae Keifer, Metaculus mangiferae Attiah (A newly recorded species in China), Spinacus pagonis Keifer (a new recorded species in Guangxi) and Spinacus longinquus Huang (a newly recorded species in Guangxi). Mango dorsal scabies mite is the dominant species of Guangxi scabies mite, its generational age at 27 ℃ 11.34 d. Scabies mite mites on the leaves of the population density up to 47 head / cm2, serious damage can lead to detached leaves of mango shoots. 15% pyridaben EC 2500 times, 40% propargite EC 1500 times, 20% of dinotefuran SG 2000 times on the mango scabies eggs in the mortality rate of 86% or more, the adult mite kill mortality Above 91.0%. Common acaricides and some insecticides on the fruit spider mites have very good control effect.
