Distribution and Economic Importance of Aphis (aphis) Craccivora Koch, 1854 (aphidini: Aphidinae: Aphididae: Hemiptera) and Its Food Plants in India
The black bean aphid, Aphis craccivora was described by Koch in 1854 from Germany. Recently, the genus Aphis Linnaeus, 1758 is subdivided into 6 subgenera : Aphis (s.s.), Bursaphis Baker, 1934, Iowana Hottes, 1954, Maculaphis Zhang and Zhang, 2002, Pseudoprotaphis Kadyrbekov, 2001, Toxoptera Koch, 1856 and Zyxaphis Knowlton, 1947 (Favret, 2016). Aphis craccivora is kept under subgenus Aphis. In...
متن کاملDifferential Induction of Flavonoids in Groundnut in Response to Helicoverpa armigera and Aphis craccivora Infestation
Flavonoids are important plant secondary metabolites, which protect plants from various stresses, including herbivory. Plants differentially respond to insects with different modes of action. High performance liquid chromatography (HPLC) fingerprinting of phenols of groundnut (Arachis hypogaea) plants with differential levels of resistance was carried out in response to Helicoverpa armigera (ch...
متن کاملGenetic Structure of the Aphis craccivora (Hemiptera: Aphididae) From Thailand Inferred From Mitochondrial COI Gene Sequence
The cowpea aphid, Aphis craccivora Koch (Hemiptera: Aphididae), is one of the most destructive insect pests of legume plants worldwide. Although outbreaks of this pest occur annually in Thailand causing heavy damage, its genetic structure and demographic history are poorly understood. In order to determine genetic structure and genetic relationship of the geographic populations of this species,...
متن کاملBiology and Demographic Growth Parameters of Cowpea Aphid (Aphis craccivora) on Faba Bean (Vicia faba) Cultivars
The performance of cowpea aphid, Aphis craccivora Koch. (Hemiptera: Aphididae), on five faba bean, Vicia faba L. (Fabales: Fabaceae) cultivars was evaluated. Colony development, biology, and demographic parameters were studied to measure the cowpea aphid performance. Two methods, whole plant and detached leaf, were used in these experiments. After 14 d , the number of apterous adult, nymphs, an...
متن کاملترجیح مراحل مختلف رشدی شته سیاه یونجه Aphis craccivora Koch (Hom.: Aphididae) توسط زنبور پارازیتویید [Lysiphlebus fabarum Marshall (Hym.: Aphidiidae)]
The host-stage preferences of alfalfa black aphid, Aphis craccivora, by parasitoid wasp, Lysiphlebus fabarum, were studied under two trials under growth chamber conditions (55±5 %, R. H., L:D 14:10 H. and Tem. 20 ±2° C ). In the first trial, all stages of aphid in equal ratios, and in the second trial, variable ratios of 5:15, 15:15 and 15:5 of 3rd and 4th instar nymphs were used for parasitisa...
