Within-tree distribution of seven insect pests of soursop (Annona muricata) in Honduras.
The spatial distribution of Corythucha gossypii, Calloconophora caliginosa, Membracis mexicana, Parasaissetia nigra, Saissetia oleae, Bephratelloides cubensis and Cerconota anonella on soursop (Annona muricata) was investigated during 1991 at 4 orchards in Honduras. All insects, except P. nigra and S. oleae, were mainly found in the middle third of the tree canopy. P. nigra and S. oleae were mainly found in the middle and bottom sections. Infestations by P. nigra were greater on the southern side of trees, whereas infestations by C. anonella were greater on the northern side.
