摘要: 1998~1999年在吉林省用性诱剂水盆监测二化螟雄蛾季节动态和发生世代,结果发现,1998年长春市越冬代成虫始见期在 5月中旬,柳河县在 5月底左右,长春市成虫终见期,1998和 1999年分别为 9月下旬和上旬。可见长春市二化螟成虫全季活动期可能长达 4个月,而 1个世代的历期约为 2个月。 1999年长春市出现两个相距 5 5天的明显蛾峰,表明存在相当高的二代转化率,从而有助于改变该地二化螟常年只发生 1代的传统观点.

Abstract: A two-year investigation was made on the seasonal population dynamics and number of generations of the rice stem borer, Chilo suppressalis(Walker)(Lepidoptera: Pyralidaer), by use of sex pheromone trapping at two sites during 1998~1999. The results showed that the overwintering generation moths were first caught in mid May at Changchun City and to the end of May at Liuhe County in 1998. The last flight dates of moths at Changchun City were in the late and early September in 1998 and 1999, respectively. The active duration of the moths was as long as four months while one generation could complete its development(egg to egg)within two months at the location. In fact, there were two obvious peaks of moth flight at Changchun City in 1999, and the interval between the peaks was about 55 days. These indicated a high percentage of occurrence of the second generation and thereby promoted to change the long standing opinion that there was only one generation at the locations in a common year.
