【背景】热带拂粉蚧属于粉蚧类昆虫,食性杂,是危害热带和亚热带水果、蔬菜和园林植物的重要害虫,主要随水果、苗木和交通工具等介质进行远距离传播。2014年5月,在我国云南与缅甸边境发现该虫危害草本植物马松子。【方法】在收集整理热带拂粉蚧生物学、地理学等信息的基础上,介绍了其主要形态特征、寄主、分布、生物学特性,并对该有害生物的危害和防治进行了综合分析。【结果】热带拂粉蚧雌成虫长椭圆形,触角8节,体长2.5~3.0 mm,宽1.5~2.0 mm,主要通过孤雌生殖繁殖后代,形态特征与双条拂粉蚧非常相似。我国的广东、广西、海南、云南、福建等热带地区适合该虫生存和危害,一旦入侵我国会对花卉、水果和蔬菜等造成危害,给相关产业带来损失。【结论与意义】热带拂粉蚧在我国有传播扩散的可能,加强检疫是防范该虫入侵的主要手段,生物防治是治理该虫的重要措施。
【Background】 Tropical mealybugs, belonging to insects of mealybugs scale, are miscellaneous foods. They are important pests that endanger tropical and subtropical fruits, vegetables and garden plants. They are mainly distributed with media such as fruits, seedlings and vehicles. In May 2014, the insect was found to harm M. juniper in the border between Yunnan and Myanmar in our country. 【Method】 The main morphological characteristics, host, distribution and biological characteristics of Myzus persicae were summarized on the basis of collecting the biology and geography information of Myzus persicae, and the damage and control of the pest were analyzed comprehensively. 【Result】 The results showed that the female adults of Ophiopogon japonicus were oval in shape with 8 antennae, 2.5-3.0 mm in body length and 1.5-2.0 mm in width. The adults were reproductive mainly through parthenogenesis, and their morphological characteristics were very similar to those of the two species. The tropical areas of Guangdong, Guangxi, Hainan, Yunnan and Fujian of our country are suitable for the survival and harm of the insects. Once invaded, our country will endanger the flowers, fruits and vegetables and bring losses to related industries. 【Conclusion and significance】 tropical mealybugs can spread and spread in our country. Strengthening quarantine is the main measure to prevent this pest invasion. Biological control is an important measure to control this pest.
