Insect Pests: The nymph of the psyllid (Heteropsylla cubana Crawford) attacks young
shoots that die back in Haiti and causes considerable damage throughout SE Asia. Natural
enemies, both parasitic and predatory, keep psyllids from reaching epidemic levels in the
Caribbean. Lepidopteran larvae (Heliothis zea) defoliate young trees in Puerto Rico. Mealy
bugs (Pseudococcus citri Risso and Ferrisia virgata Ckll.) feed on seed pods in Indonesia
and the Philippines. A twig girdler (Oncideres rhodosticta) attacks trees in Texas. The coffee
bean weevil (Araecerus fasciculatus De Geer) attacks seeds in the Philippines, feeding
on the cotyledon. Other insect pests ofthe Philippines include: the scarab beetles (Anomala
sp., Adoretus sp., and Holotrichia sp.) that feed on seedling roots; coleopteran and lepidopteran
stem borers, including Zeuzera coffeae and Cossus sp.; lepidopteran defoliators
(Orgyia australis postica, Lymantria sp.); an undetermined microlepidopteran species that
feeds on the cotyledons and seedcoats of seeds inside pods; Gryllotalpa africana
(Orthoptera: Gryllotalpidae) and Phaneroptera furcifera (Orthoptera: Tettigoniidae) that
feed on the roots and flowers, respectively; an undetermined diaspidid (Homoptera:
Diaspididae) that sucks sap from seedling stems and leaves, causing defoliation; and a burrowing
cydnid (Hemiptera: Cydnidae) that sucks sap from the roots.
Other Pests: The Hispaniolan Woodpecker (Melanerpes striatus) and Yellow-bellied
Sapsucker (Sphyrapicus varius) wounds the bark to feed on insects and sap, usually at

Rico. Leaf pustules caused by Camptomeris leucaenae (EL. Stevens & Dalby) Syd. has
been reported in Puerto Rico, Dominican Republic, Colombia, and Venezuela. Dieback
(Botryosphaeria ribis var. chromogena Shear, Stevens & Wilcox and Phylsalospora
obtusa (Schw.) Cke.) affects branches in Hawaii. Seed pod rot includes the following
fungi: Colletotrichium gloeosporioides (Penzig) Penzig & Sacco occurs in Mauritius;
Pseudomonas fluorescens and Fusarium sp. occurs in Colombia. Root rot includes the
following fungi species: Fomes lamaoensis (MuIT.) Sacco & Trott, Helicobasidium compactum
