INSECT PESTS SURVEY ON ACACIA PLANTATION IN VIETNAM Dao Ngoc Quang1*, Pham Quang Thu1 and Le Van Binh1 1 Forest Protection Research Centre, Vietnamese Academy of Forest Sciences *Corresponding author: [email protected] Introduction Over the past three decades plantings of exotic species of Acacia in Vietnam have increased markedly, and it is anticipated that such plantings will continue to expand. Previous surveys have revealed that these species are susceptible to a range of pests and diseases, already present in Vietnam. Exotic pests and diseases also pose serious threats. Comprehensive surveillance and a database of pest and disease records are critical to producing pest lists, detecting incursions, and managing outbreaks of pests and diseases. Methods - Field observations were carried out in 2012 and 2013 in Acacia plantations in all 9 ecological zones of Vietnam. - All major pests associated with Acacia plantations have been identified as far as is possible given current, scientific knowledge. - All insect pest specimens were deposited in Forest Protection Research Centre, Vietnamese Academy of Forest Sciences (VAFS). Results From health survey conducted by Forest Protection Research Centre in 2012 and 2013 in Acacia plantations, there are 99 main insect pest species associated with Acacia auriculiformis, A. mangium and Acacia hybrid in Vietnam, with the following orders represented: Coleoptera (29), Orthoptera (26), Lepidoptera (25), Hemiptera (15), Isoptera (2), Homoptera (1), and Phasmida (1). In all, 99 species are listed, some species such as: Acanthopsyche sp., Dasychira checkiangensis, Ericeia sp., Holotrichia sauteri, Hypomeces squamosus, Phalera grotei, Stauropus fagi, Pupae Adult Larva Xylosandrus crassiusculus, Xystrocera festiva are Phalera grotei the most serious pests of Aacia plantation.

Adult Discussion Recently, some new insect pests of trees in acacia plantations in Vietnam has emerged: Chlorophorus sp., Ericeia sp., Euwallacea fornicatus, Indarbela quadrinotata, Phalera grotei, Sinoxylon anale, Xystrocera festiva, these are biosecurity threats. With the current trend of international cooperation, sharing a list of pests and diseases of plantation trees with other countries in the world is the responsibility of each country, including Vietnam. Sharing information in this field will help to effectively manage and quarantine pests and diseases on a large scale, especially beyond the control of each country. Tel.
