It was determined the incidence of HypsipylagrandellaZ. in Cedrelaodorata andSwieteniahumilis in an agroforestry system. The design was incomplete blocksin which investigates the"Evaluation of growth, potential for kidnapping and carbon fixation of six forest species associated with MussabalbisianaABB. The area consists of 5 blocks and 28 plots where sampled every 8 days 100% of the plants between August 2013 and November 2014. Registration is the height of the plant, height of the damage, number of larvae present in the plant and the rainfall. Test was conducted of averages of LSD and Infostat Fisher sand found that the damage was greater in associated species, that in the not associated (p < 0.05) in this sense C. odorata with guineo (CR-G) presented the greatest affectation (21.3 %).But when we compare these results with those of Newton et al (1998), the proportion of affected plants is low.In the area without associated with a higher impact was recorded in S. humilisalthough in smaller proportion than in the associated area in the months of highest precipitation is where you record the greater involvement of H grandella must therefore be increase the management efforts during this time to minimize the damage.
