摘要
【目的】番茄潜叶蛾Tuta absoluta是一种对番茄具有毁灭性危害的世界性入侵害虫,本研究旨在探索温度对入侵番茄潜叶蛾种群生长发育和繁殖的影响,为预测番茄潜叶蛾的分布区域、田间发生动态提供基础。【方法】在室内测定了番茄叶片上番茄潜叶蛾在15,20,25,30和35℃5个恒定温度条件下各虫态的发育历期和存活率、繁殖力和种群增长参数,并应用不同模型分析发育速率、内禀增长率和净生殖率与温度的关系,估计发育起点温度、发育极限温度、发育最适温度、有效积温和年发生代数。【结果】在恒温15~30℃范围内,番茄潜叶蛾各虫态的发育历期随温度升高而逐渐缩短。25℃下幼虫期存活率、成虫前期存活率、雌虫总产卵量、净生殖率、内禀增长率和周限增长率均最大。在35℃下,卵的存活率骤降至11%,孵化的幼虫无法正常发育。卵期、幼虫期、蛹期、成虫前期、全世代的有效积温分别为104.17,232.59,129.87,434.78和526.32日·度,该虫在新疆伊宁县和察布查尔锡伯自治县的理论发生代数为4~5代。基于发育速率与温度关系的模型与基于种群增长参数与温度关系的模型所计算的积温需求参数不同,基于内禀增长率求得的番茄潜叶蛾的发育起点温度、发育极限高温和发育最适温度分别为12.46,30.40和27.36℃。【结论】入侵我国新疆地区的番茄潜叶蛾适温范围广泛,在我国大部分地区具有极高的扩散风险。
【Aim】The tomato leaf miner,Tuta absoluta,is a devastating invasive alien pest worldwide,causing severe damage to global tomato industry.In this study,the effects of temperature on the growth,development and reproduction of T.absoluta were studied in order to provide the basic information for prediction of its potential distribution and population dynamics in newly invaded areas.【Methods】The developmental duration,survival rate and population growth parameters of T.absoluta on tomato leaves under laboratory conditions were investigated,and the lower temperature threshold,upper temperature threshold,optimum temperature,effective accumulative temperature and occurrence generation were determined by using models based on developmental rates or population growth parameters.【Results】Within the constant temperatures ranging from 15 to 30℃,the duration of different developmental stages of T.absoluta shortened as the temperature rose.At 25℃,the survival rate at the larval and entire immature stages,the total fecundity,the net reproductive rate,the intrinsic rate of natural increase and the finite rate of increase were all the greatest.At 35℃,the survival rate of eggs decreased sharply to 11%,and the larvae could not finish development.The effective accumulative temperatures of egg,larval,pupal,entire immature stages and the whole generation were 104.17,232.59,129.87,434.78 and 526.32 degree-days,respectively.T.absoluta could have four to five generations per year in Yining County and Qapqal Xibe Autonomous County,Xinjiang.Thermal requirement parameters estimated by the model based on the relationship between the developmental rate and temperature showed different results from those by the model based on the relationship between the intrinsic rate of natural increase and temperature.The lower temperature threshold,upper temperature threshold and optimum temperature based on the intrinsic rate of natural increase were 12.46,30.40 and 27.36℃,respectively.【Conclusion】The range of adaptive temperature f
