摘要:

【目的】 研究不同氮素含量人工饲料对亚洲玉米螟Ostrinia furnacalis(Guenée)生长发育和繁殖的影响,分析玉米螟种群激增的内在N素营养驱动。【方法】 测定5个氮素含量水平(3.94%、7.33%、10.69%、18.84%、30.31%)人工饲料对亚洲玉米螟个体生长发育及种群增殖的影响,构建实验种群生命表。【结果】 25℃,低氮水平N1(氮素含量3.94%)幼虫发育缓慢且未能正常羽化,当氮素含量增加到18.84%(N4)时,幼虫历期明显缩短,内禀增长率(0.13)、净增殖率(66.14)、周限增长率(1.14)、孵化率(90.06%)最高,平均世代历期(30.79)、种群加倍时间(5.17)最短,并与其他4个氮素水平有显著差异(P<0.05),且其化蛹率(98.66%)、羽化率(95.45%)、存活率(91.33%)、平均单雌产卵量(120.12±9.73)最高;但当氮素含量提高到30.31%后,内禀增长率(0.04)、净增殖率(44.71)、周限增长率(1.04)最低,平均世代历期(92.36)、种群加倍时间(16.85)最长,25和30℃结果与20℃接近。3个温度各处理蛹期、成蛾寿命、雌虫生殖力无显著差异(P>0.05)。【结论】 氮素含量对亚洲玉米螟个体发育与种群增殖关系密切,在一定区间内随氮含量增加生长加快,种群增殖能力增强,且高氮30.31%和低氮3.94%均对玉米螟生长有明显抑制作用。

Abstract:

【Objective】 To clarify the effects of artificial diets with different nitrogen contents on the growth, development and reproduction of the Asian corn borer (Ostrinia furnacalis), and to explore the intrinsic N factors of different nitrogen treatments on the interaction of corn and pests and the surge of corn borer populations driven nutritionally.【Method】 In the laboratory, five different nitrogen content feeds with nitrogen contents of 3.94%, 7.33%, 10.69%, 18.84%, and 30.31% were set to determine the effects of different nitrogen contents on the growth and development of the Asian corn borer.After that, the experimental population life table of the Asian corn borer was established.【Results】 At 25℃ the low nitrogen level N1 (nitrogen content 3.94%) failed to emerge normally, and the larval development period was the longest.When the nitrogen content increased to 18.84% (N4), the intrinsic growth rate (0.13) and net proliferation (66.14), weekly growth rate (1.14), hatching rate (90.06%) the highest, average generation period (30.79), population doubling time (5.17) the shortest, which significantly different from the other four nitrogen levels (P<0.05), the larval duration was significantly shortened, the N4 pupation rate (98.66%), emergence rate (95.45%), survival rate (91.33%), and average egg production per female (120.12±9.73) were the highest, but when the nitrogen content reaching 30.31%, the intrinsic growth rate (0.04), net multiplication rate (44.71), and weekly growth rate (1.04) the lowest, the average generation period (92.36), and the population doubling time (16.85) the longest, at 25 and 30℃ s close to that at 20℃.In addition, there was no significant difference in the pupal stage, adult moth lifespan, and female fecundity between the three temperature treatments (P>0.05).【Conclusion】 Nitrogen content is closely related to the individual development of the Asian corn borer and the population multiplication.In a certain interval, with the increase of nitrogen content, the growth speeds up and the population multiplication ability is enhanced.nitrogen 30.31% and low nitrogen 3.94% have a significant inhibitory effect on the growth of corn borer.
