RESISTANCE OF DIFFERENT BEAN GENOTYPES (Phaseolus vulgaris L.) TO Aphiscraccivora Koch, 1854

摘要

The black aphid (Aphis craccivora Koch, 1854, Hemiptera: Aphididae) is an important pest to the species of beans Phaseolus vulgaris L. and Vigna unguiculata (L.) Walp., due to its ability to cause damage by sucking of sap and the virus transmission asCowpea aphid borne mosaic virus (CABMV), Blackeye cowpea mosaic virus (BICMV) and Bean common mosaic virus (BCMV) which lead to losses in production. The main control method has been chemical insecticides spraying, which often cause imbalance to the agroecosystem and can cause resistance problems. Thus it is desirable to look for more sustainable controlling methods, following the example of the use of cultivars that show some type of resistance. The study aimed to evaluate possible resistance of different genotypes of common beans P. vulgaris to the A. craccivora.
