ESTUDIO DE LA INCIDENCIA DE PLAGAS Y ENFERMEDADES EN UNA COLECCIÓN DE CONCHITA AZUL (CLITORIA TERNATEA)

The present work was carried out to identify the insect population associated to a collection of 16 accessions of butterfly pea (Clitoria ternatea) under field introduction conditions of the Experimental Station of Grasses and Forages of Sancti Spiritus province, Cuba as well as to describe the insect-plant relationship established. Results showed that the most important damages were mainly due to species of Coleoptera, Lepidoptera and Hemiptera orders, although none reached the pest threshold but Homoptera order had the lowest incidence. At the final stages of the experiment there were severe damages caused by Rhizoctonia solani which destroyed the majority of the accessions under study, surviving only SC-80, SC-163, and SC-135 this latter showed the highest resistance to fungus attack. It is concluded that accessions resistant to R. solani fungus could be relevant in the programs for the introduction of this germ plasm.
