Penekanan Penularan Bean Common Mosaic Virus oleh Efek Penghambat Makan Kitosan Terhadap Aphis craccivora Koch. (Bean Common Mosaic Virus Transmission Inhibition by Antifeedant Chitosan Against Aphis craccivora Koch.)

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...

Biology 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...

RNAi-mediated resistance to Bean golden mosaic virus in genetically engineered common bean (Phaseolus vulgaris).

Bean golden mosaic virus (BGMV) is transmitted by the whitefly Bemisia tabaci in a persistent, circulative manner, causing the golden mosaic of common bean (Phaseolus vulgaris L.). The characteristic symptoms are yellow-green mosaic of leaves, stunted growth, or distorted pods. The disease is the largest constraint to bean production in Latin America and causes severe yield losses (40 to 100%)....

NL-3 K Strain Is a Stable and Naturally Occurring Interspecific Recombinant Derived from Bean common mosaic necrosis virus and Bean common mosaic virus.

ABSTRACT A strain of Bean common mosaic necrosis virus (BCMNV) from Idaho was identified by enzyme-linked immunosorbent assay using monoclonal antibodies and determined to be similar to the NL-3 D strain (of Drifjhout) by reaction of differential bean cultivars. However, this BCMNV strain (designated NL-3 K) caused earlier and more severe symptoms on bean plants representing host groups 0, 4, a...
