| Abstract: | According to investigations on the insect population density of mulberry thripses onmulberry branches,it is clear that mulberry thripses mainly assemble on branches withleaves in the order of 0 to 8. As mulberry branches stop growing and the tree vitalityweakens in autumn,mulberry thripses ascent to the branches with leaves in the order of0 to 4.The investigation in mulberry fields showed that the main natural enemies ofmulberry thrips are Chrysopa septempunctata Wesmad, Chrysopa sinica Tjedar,Haplothrips chinensis Priesner,Orius similis Zheag,Scirtothrips takahashi Priesner. |
