摘要
Caligula Japonica has continuously broken out in large scale in Longnan City, Gansu Province of China, causing heavy economic losses. In order to ef- fectively control the insect and to increase the production benefit of walnut in Longnan, the authors have investigated and observed the morphological characters and living habits of C. Japonica. The major causes of continuous large-scale occurrence of C. Japonica in Longnan City are analyzed concretely, and the integrated con- trol measures are put forward from the aspects of silvicultural measures, physical control, chemical control and biological control.
