Effect of exogenous salicylic acid on the demographic characteristics of <em>Myzus persicae</em> (Sulzer) (Hemiptera: Aphididae) to potato plants
收藏资源简介：
Myzus persicae (Sulzer) (Hemiptera: Aphididae) is an economically important pest of potatoes. Salicylic acid (SA), a key plant hormone, plays an important role in plant growth and stress resistance. However, the role of SA in inducing potato resistance to M. persicae remains poorly understood. This study investigated the effect of foliar application of SA at different concentrations (0.05 mM, 0.5 mM, and 5 mM) on the demographic characteristics of M. persicae using an age-stage, two-sex life table approach. The application of 5 mM SA significantly prolonged the pre-adult developmental duration and total pre-reproductive period (TPRP). Furthermore, life expectancy (exj), reproductive duration, net maternity function (lxmx), and mean fecundity were reduced in 5 mM SA-treated plants compared to the control. Consequently, this led to a lower net reproductive rate (R0 = 42.53 offspring/female), intrinsic rate of increase (r = 0.2852 d-1), and finite rate of increase (λ = 1.3301 d-1).

桃蚜（*Myzus persicae* (Sulzer)，半翅目：蚜科）是一种具有重要经济意义的马铃薯害虫。水杨酸（salicylic acid, SA）作为关键植物激素，在植物生长与抗逆过程中发挥重要作用。然而，水杨酸诱导马铃薯抗桃蚜的作用机制仍不甚明晰。本研究采用年龄-阶段两性生命表（age-stage, two-sex life table）方法，探究不同浓度（0.05 mM、0.5 mM及5 mM）水杨酸叶面喷施对桃蚜种群特征的影响。结果显示，5 mM水杨酸处理显著延长了桃蚜的未成虫发育期与总预繁殖期（TPRP）。相较于对照组，5 mM水杨酸处理组桃蚜的生命期望（e_xj）、繁殖时长、净产雌率函数（l_xm_x）以及平均繁殖力均显著降低。最终导致桃蚜的净生殖率（R0 = 42.53 头/雌）、内禀增长率（r = 0.2852 d⁻¹）以及周限增长率（λ = 1.3301 d⁻¹）均低于对照组。 数据来源：《外源水杨酸对取食马铃薯植株的桃蚜（*Myzus persicae* (Sulzer)，半翅目：蚜科）种群特征的影响》 ###### 数据集DOI：[https://doi.org/10.5061/dryad.gf1vhhn1g](https://doi.org/10.5061/dryad.gf1vhhn1g) #### 数据与文件结构说明 ##### **Raw_data.zip** 本数据集包含两个数据文件夹：**Figures**与**Tables** ###### **Figures：** 该文件夹包含用于绘制图1、图2、图3以及补充图S1、S2、S3的各类TXT文件。 * **0.05mM、0.5mM、5 mM及对照组（无水杨酸）--Fig.1_Sxj.txt：** 存储取食经0.05/0.5/5 mM水杨酸（SA）处理的马铃薯植株的桃蚜的年龄-阶段存活率（Sxj）数据。 变量（即列名）详细说明： "Age-stage survival rate"即年龄-阶段特定存活率（s_xj）：指新孵化若虫存活至年龄x、发育阶段j的概率。 N1、N2、N3等...
