Abstract

SANCHEZ-CASTRO, Adayakni et al. Leafhoppers (Typhlocybinae) and its relationship with disease symptoms in a common bean field (Phaseolus vulgaris L.). Rev. Protección Veg. [online]. 2016, vol.31, n.3, pp. 153-158. ISSN 2224-4697.

The objectives of this study were the identification of  the species of leafhoppers present in a production field of bean (Phaseolus vulgaris L.) (Cuba Cueto range 25-11) in Güines, Mayabeque, Cuba, and the observation of their relationships with disease symptoms on the plants. For this,  30 plants from three plots were sampled every seven days from January to March 2015. The collected insects were cleared and mounted on slides to be identified using taxonomic keys. A cladogram was constructed to analyze the relationships between disease symptoms on the plants and the insects. The leafhoppers identified were Empoasca kraemeri Ross and Moore, Empoasca fabae Harris, and Empoasca papayae Oman. The plants showed symptoms representative of hopperburn, phytoplasma and virus diseases, which were related to vectors

Keywords : Empoasca fabae; Empoasca kraemeri; Empoasca papayae; phytoplasma; common bean; virus.
