中文摘要:
      调查了三亚红峡谷高尔夫球场草坪不同功能区的蛴螬种类,发现危害该高尔夫球场草坪的蛴螬有铜绿丽金龟、大绿金龟、华南大黑鳃金龟和浅棕鳃金龟。其中,优势种为大绿金龟,次优势种为铜绿丽金龟。在掌握各功能区蛴螬全年的种类及数量消长情况基础上,用毒死蜱、辛硫磷和绿僵菌进行防治。试验结果表明,毒死蜱施药后15 d防效达100%;辛硫磷在施药30 d时,虫口减退率达94.58%;绿僵菌施药时间30 d防效达91.12%。可见,绿僵菌菌剂随着施药时间的增加,速效性和持效性均优于毒死蜱和辛硫磷。
英文摘要:
      An investigation was made of the grubs infesting the lawns of Sun Valley Golf Course Field in Sanya. The results showed that the grubs of several species, i.e., Anomala corpulenta, Anomala cupripes, Holotrichiasauteri and Holotrichia vata, caused damage to the golf lawn. The dominant species was Anomala cupripes, followed by Anomala corpulenta. The species and number of the grubs infesting the lawn throughout the year in different functional areas of the lawn were investigated, based on which the grubs were controlled by spraying chlorpyrifos, phoxim or metarhizium. The results showed that the golf lawn when sprayed with chlorpyriphos for 15 days had a grub control efficiency of upto 100%. After applied with phoxim for 30 days, the grub population was reduced by 95.03%. After applied with Metarhizium anisopliae for 30 days, the grub control efficiency reached 91.12%. With the time after treatment, Metarhizium anisopliae had better persistent effect on control of the grubs than chlorpyrifos and phoxim.
