The Discovery of a Green Wood Beetle Diastocera trifasciata(Coleoptera:Lamiinae)on Mango Tree in South Sudan

摘要

The green wood insect beetle which was later identified as Diastocera trifasciata((Fabricius)-tribus Ceropplesini,Coleoptera:Lamiinae)was found on September 18,2015,girdling a mango twig at Dr.John Garang Memorial University of Science and Technology(Dr.JG-MUST)campus,Bor county,Jonglei state,Republic of South Sudan.The beetle D.trifasciata attacks young vigorous growing mango branches of more than 20-35 mm circumferences.Severely cut branches dried up and broken away especially when there was a strong blowing wind or just remained dry,hung on the tree.Although this incidence may seem not to pose a significant economic threat at the moment,the authors keenly advocate for proactive pest surveillances,monitoring and evaluating its spread,impact damage level caused on mango plants in most areas of high mango productivity and developing control strategy that will prevent further devastations of mango trees,guarantee high fruit yields and ensure food security in South Sudan.
