Abstract: Seven accessions of Leucaena Benth, supported significantly different population densities of Heteropsylla cubana Crawford. The highest populations occurred on the I.. Ieucocephala (Lamb.) De Wit accessions K8, K527, and K784, the I.. diversifolia (Schlecht.) Benth, accession K156, and the L. leucocephala X I.. diversifolia accession K743. The lowest psyllid densities occurred on the L. pallida Britton and Rose accession K376. Accessions K8, K527, and K636 were the most severely damaged. Accessions K743 and K156 were often slightly damaged and only occasionally moderately damaged. Only slight damage was observed on accessions K784 and K376. Parasitism of H. cubana by Psyllaephagus yaseeni Noyes was low (1.9%), probably due to hyperparasitization levels averaging 39.6%.
