摘  要：
采用昆虫诱捕网对陇南市油橄榄多孔横沟象(Pimelocerus perforates Roelofs)种群动态进行了监测,并结合同期气象因子,分析影响其种群动态变化的关键气象因子.结果表明:陇南地区多孔横沟象一年发生2代,主要以老熟幼虫在枝干中越冬,个别出现成虫在枝干中越冬,始见成虫为3月中旬,5月上旬和8月中下旬为盛发期,11月中旬开始进入越冬期.统计分析表明,多孔横沟象在不同危害时期主要影响气象因子不同,3月中旬至5月上旬影响成虫数量的主要气象因子是降雨量(P<0.01),5月中旬至8月下旬成虫数量与平均最高温显著负相关(P<0.01),而在9月上旬至11月上旬温度(平均温度、平均最高温、平均最低温)是该阶段影响成虫数量的关键气象因子,平均温度相关性最强.

摘  要：
The population dynamics of Pimelocerus perforates Roelofs in Longnan City were monitored by insect traps,and the key meteorologi-cal factors affecting the population dynamics were analyzed in combination with the meteorological factors in the same period.The results pro-vide a basis for the prediction and scientific prevention and control of Pimelocerus perforates Roelofs in Longnan City.The results showed that there were two generations per year in Longnan area.The mature larvae mainly overwintered in the branches,and some adults overwintered in the branches.The adults were first seen in mid-March,peaked in early May and mid-late August,and began to overwinter in mid-November.Statistical analysis showed that the main meteorological factors affecting the number of adults were different in different damage periods.From mid-March to early May,the main driving factor for the number of adults was rainfall(P<0.01).From mid-May to late August,the number of adults was significantly negatively correlated with the average maximum temperature(P<0.01).From early September to early November,temperature(average temperature,maximum temperature,minimum temperature)was the key meteorological factor affecting the number of a-dults at this stage,and the average temperature had the strongest correlation.
