摘要
通过诱捕的方式对云南省元江县芒果园橘小实蝇种群变动规律进行了全年监测,并就气候因素对当地橘小实蝇种群变动的影响进行了分析。研究结果表明,元江芒果园内橘小实蝇可常年发生,11月至翌年4月种群数量相对较低,5月以后种群数量开始增长,至8月达到高峰。逐步回归分析揭示,降雨量、平均日照时数、月极端最高温和最低温是影响5—10月元江县芒果园橘小实蝇种群数量的关键因子;相对空气湿度、风速、平均日照时数、月极端最低温则是影响11月至翌年4月种群数量变动的关键气候因子。
Annual monitoring was conducted on the population dynamics of the oriental fruit fly, Bactrocera dorsalis （ Hendel ） （ Diptera ： Tephritidae）through methyl eugenol-baited traps in all 2011.During the study periods,this pest occurred all year in Yuanjiang County.The fly population remained low from November to next year April,and then increased steadily until August when it reached a peak.Stepwise regression analysis demonstrated that during the period from May to October, monthly rainfall, average sunshine time, monthly maximum temperature and monthly minimum temperature impacted the population dynamics ,during the period from November to next year April,air humidity ,wind speed,average sunshine time and monthly minimum temperature impacted the population dynamics.
