摘要
连续4年对桂林北部全州县柑橘园的橘小实蝇进行田间消长动态监测,并根据当地气象资料分析气象因素与橘小实蝇发生动态的关系。结果表明,橘小实蝇在当地于5月下旬至7月中旬开始活动,9月上旬至11月下旬之间会出现2次活动高峰期,12月上旬以后活动停止或减弱;气温和日照时数是影响当地橘小实蝇活动动态的主要气象因子。
Population dynamics of Bactrocera dorsalis( Hendel) has been monitoring for 4 years in citrus orchards in Quanzhou County in northern Guilin, and the relationship between the population dynamics and meteorological factors was analysed according to local meteorological data.The results showed that B. dorsalis began to move between late May to mid-July, appeared 2 times activity peaks from early September to late November,stoped or reduced activity after early December. The main meteorological factors affecting the local population dynamics of B. dorsalis were temperature and sunlight time.
