| 草地贪夜蛾是2019年入侵我国的一种迁飞性害虫,已成为严重影响我国玉米生产的重要害虫。本试验在室内条件下研究了花丝、雌穂、心叶和功能叶对草地贪夜蛾生长发育及营养效应的影响。结果表明:玉米功能叶组在各发育阶段的死亡率显著高于其他几组,且幼虫期最长(23.29 d±0.49 d);心叶组蛹重最重(270.89 mg±3.87 mg),且成虫产卵量及卵孵化率最高,分别为973粒和97.82%;雌穂组及心叶组的相对取食量较高,分别为(1.680 mg±0.013 mg)和(1.690 mg±0.004 mg);花丝组、雌穂组及心叶组的食物转化率及食物利用率差异不显著,均高于功能叶组。上述结果表明,与玉米功能叶相比,雌穂及心叶等幼嫩组织更适合草地贪夜蛾生长发育及营养积累。 |

| As a migratory pest that invaded China in 2019, Spodoptera frugiperda has become an important pest that seriously affects China’s maize production. The effects of maize silk, immature ear, heart leaves and functional leaves on the growth, development and nutrition of S. frugiperda were studied in laboratory. The results shown that the mortality in the group fed on functional leaves was significantly higher than that in other groups, and the period of larval stage was the longest (23.29 d±0.49 d). The pupa weight in the group fed on heart leaf was the heaviest (270.89 mg±3.87 mg), and the fecundity of single female adult and egg hatching rate were the highest (973 eggs and 97.82%, respectively). The food intake of the groups fed on immature ear and the heart leaves was 1.680 mg±0.013mg and 1.690 mg±0.004 mg, respectively, which was higher than that of the group fed on functional leaves. These results indicated that, compared with the functional leaves of maize, the young tissue such as female tassels and heart leaves were more suitable for the growth, development and nutrient accumulation of the S. frugiperda . |
