中文摘要:

【目的】 为了明确不同营养组分配方的人工全纯饲料对桃蚜Myzus persicae(Sulze)生长发育的影响,筛选出适合室内饲养桃蚜的人工饲料配方【方法】 本文以5组不同浓度的氨基酸溶液(A1 =    50 mmol/LA2=100 mmol/LA3=150 mmol/LA4=200 mmol/LA5=250 mmol/L)和4组不同浓度的蔗糖混合液(S1= 250 mmol/LS2=500 mmol/LS3=750 mmol/LS4=1 000 mmol/L组配的混合液饲喂桃蚜,测定了桃蚜的存活率存活时间、平均产和产仔率,并利用生命表技术,分析不同处理对桃蚜实验种群生命参数的影响。【结果】 结果表明,不同饲料配方对桃蚜的存活及繁殖均有一定的影响。存活率A1S3A1S4A3S4最高,三者之间差异不显著(P>0.05);存活时间A1S3A1S4A3S4最长,分别达到了34.00±1.00d33.33±1.1530.6±4.04d,三者之间差异不显著(P>0.05;平均产仔量和产仔率以A3S1A3S4最大A3S1分别达到了9.75±2.71/成蚜43.33%±15.28%A3S4分别达到了9.43±2.27/成蚜50.00%±10.00%,二者之间差异不显著P>0.05种群生命参数中,A3S1A3S4的净生殖率分别达到了(4.43±2.31)和(4.63±1.25),二者之间差异不显著(P>0.05),与其他饲料配方差异显著(P<0.05)。【结论】 综合所有参数比较,确定A3S4为桃蚜的最佳人工饲料配方。

英文摘要:

 [Objectives]  To investigate the effects of artificial diets containing different nutritional components on the growth and development of the peach aphid, Myzus persicae (Sulze), and to develop a method to screen artificial diets for rearing the peach aphid in captivity. [Methods]  Peach aphids were fed artificial diets containing one of 5 different concentrations of amino acid solution (A1=50 mmol/L, A2=100 mmol/L, A3=150 mmol/L, A4=200 mmol/L, A5=250 mmol/L) and one of 4 different concentrations of sucrose mixture (S1=250 mmol/L, S2=500 mmol/L, S3=750 mmol/L, S4=1 000 mmol/L). The survival, longevity, and fecundity, of aphids fed on each diet were determined, and the effects of the different diets on aphid life parameters were analyzed using life table techniques. [Results]  Survival and fecundity were significantly affected by the different artificial diets. Aphids that received the A1S3, A1S4 and A3S4 diets had the highest survival rates. There was no significant difference in the longevity of aphids that received these three diets, which were (34.00±1.00) , (33.33±1.15) and (30.6±4.04)d, respectively. Aphids that received the A3S1 and A3S4 diets had the highest number of eggs laid per female and the highest average fecundity; (9.75±2.71) vs (9.43±2.27), and 43.33%±15.28% vs 50.00%±10.00%, respectively. There was no significant difference between these two diets in these parameters. The reproductive rates of aphids that received the A3S1 and A3S4 diets were (4.43±2.31) and (4.63±1.25), respectively; significantly higher (P<0.05) than those of aphids that received the other artificial diets. [Conclusion]  The A3S4 was the best of the diets tested for captive rearing peach aphids.
