The population abundance, infestation, and harmful effects of the aphid Aphis craccivora Koch (Hemiptera: Aphididae) were studied on four bean plant species, namely the country bean (Lablab purpureus var. BARI Seem 1), the yard‐long bean (Vigna sesquipedalis var. BARI Borboti 1), the hyacinth bean (Dolichos lablab var. BARI Seem 6), and the bush bean (Phaseolus vulgaris var. BARI Jar Seem 3). Aphid abundance and infestation on the leaves, inflorescences, flowers, and pods differed significantly among the bean plant species, with P. vulgaris and V. sesquipedalis having the lowest and highest results, respectively. Aphid severity grade and the number of trichomes of the bean plant species were negatively correlated. The duration of the growth stages among the bean plant species were significantly different, with V. sesquipedalis having the shortest durations. Aphid abundance and infestation significantly affected the physical and phytochemical characteristics of the bean plant species. The highest reduction of number of leaves, flower inflorescences, and pod inflorescences per plant, and moisture and chlorophyll content in the leaves was found in L. purpureus. The results for V. sesquipedalis revealed the highest reduction in plant height, seed weight, and pH, while those of D. lablab showed the highest reduction in leaf area.

蚜虫种群丰度和对各种豆类植物的有害影响

研究了蚜虫 Aphis craccivora Koch(半翅目:Aphididae)对四种豆类植物的种群丰度、侵染和有害影响,即乡村豆(Lablab purpureus var. BARI Seem 1)、长豆(Vigna sesquipedalis var. BARI Borboti 1)、风信子豆(Dolichos lablab var. BARI Seem 6)和灌木豆(Phaseolus vulgaris var. BARI Jar Seem 3)。不同豆类植物的叶、花序、花和豆荚上的蚜虫丰度和侵染情况存在显着差异,其中 P. vulgaris 和 V. sesquipedalis 分别具有最低和最高的结果。蚜虫严重程度与豆科植物毛状体数量呈负相关。豆类植物物种之间的生长阶段持续时间显着不同,V。具有最短持续时间的倍半足。蚜虫的丰度和侵染显着影响了豆类植物的物理和植物化学特性。在 L. purpureus 中发现每株植物的叶子、花花序和豆荚花序数量以及叶子中水分和叶绿素含量的减少幅度最大。V. sesquipedalis 的结果显示植物高度、种子重量和 pH 值的降低幅度最大,而 D. lablab 的结果显示叶面积的降低幅度最大。
