摘　　要：马铃薯甲虫Leptinotarsa decemlineata是世界性检疫害虫,是影响我国马铃薯生产最严重的害虫之一。通过4种不同的施氮量(N_(ck)=0 kg/hm^(2)、N_(低)=80 kg/hm^(2)、N_(中)=120 kg/hm^(2)和N_(高)=240 kg/hm^(2))调查马铃薯甲虫的生长发育和成虫繁殖情况。结果表明不同施氮量下马铃薯甲虫均能完成一个世代。总体而言,数据趋势一致表明N_(CK)和N_(高)处理(种植时总施氮量)的幼虫、成虫、卵数以及种群动态预测结果均高于N_(低)、N_(中)处理。各处理间种群参数内禀增长率(r)、周限增长率(λ)和净增殖率(R_(0))差异均不显著;而N_(ck)、N_(低)、N_(中)和N_(高)处理在总生殖率(GRR)和平均世代时间(T)中存在显著差异,且N_(高)显著高于其他。本文通过设置不同施氮量对马铃薯甲虫发育及种群增殖的影响,了解氮肥的施用量对马铃薯甲虫的生长发育存在的影响,为寻找减少碳排放和发展可持续的防治方法控制害虫为害。Leptinotarsa decemlineata,a worldwide quarantine pest,is known to be one of the most serious pests that significantly impact potato production in China.The growth and development and adult reproduction of Colorado potato beetles were investigated by four different amounts of nitrogen(N_(ck)=0 kg/hm^(2),N_(low)=80 kg/hm^(2),N_(middle)=160 kg/hm^(2),N_(high)=240 kg/hm^(2)).The results showed that all Colorado potato beetles could complete one generation under different nitrogen application levels.The data trends indicated that the number of larvae,adults,eggs,and population dynamics of the N_(CK)and N_(high)treatments(total nitrogen applied at planting)were higher compared to the Nlow and Nmiddle treatments.There were no significant differences in population parameters such as intrinsic growth rate(r),weekly growth rate(λ),and net proliferation rate(R_(0)).However,N_(CK),Nlow,Nmiddle,and N_(high)treatments differed significantly in total reproductive rate(GRR)and mean generation time(T),with N_(high)being significantly higher than the others.This paper explores the effects of different nitrogen-stressed levels on the development of Colorado potato beetles and population proliferation.Studying the impact of nitrogen fertilizer application on the growth and development of Colorado potato beetles not only helps in reducing carbon emissions but also aids in the development of sustainable control methods to control pests.
