通过田间调查和室内观测,研究了大栗鳃金龟发育历期、越冬状况、幼虫周年垂直活动规律、成虫消长发生危害规律。采用回归与相关分析法、期距法、物候期法、有效基数预测法进行了发生期和发生量预测,经过3年实际应用预测结果和实际发生基本一致。 Through the field investigation and indoor observation, the developmental history, overwintering condition, vertical movement of larvae, and the occurrence and damage of adults were studied. The incidence and the amount of occurrence were predicted by regression and correlation analysis, period method, phenophase method and effective base prediction method. The predicted results were basically consistent with the actual occurrence after 3 years of practical application.
