Biological Control of the Hibiscus Mealybug, Maconellicoccus Hirsutus Green (Hemiptera: Pseudococcidae) in the Caribbean
The hibiscus mealybug, Maconellicoccus hirsutus Green, was first reported in the Caribbean in 1994 in Grenada and by the beginning of 2001, it had spread to over 25 territories from Guyana and Venezuela in the South to Bahamas in the North.
Rhythmic foraging in the leaf-cutting ant Atta cephalotes (L.) (Formicidae: Attini)
The main object of this paper is to describe the collective aspects of foraging, especially diel and long-term rhythms, to see whether the ants' characteristic cyclical behaviour depends on widespread physical changes in their environment.
Screening of medicinal plants from Trinidad and Tobago for antimicrobial and insecticidal properties.
Micro-environmental factors affecting diel patterns of foraging in the leaf-cutting ant Atta cephalotes (L.) (Formicidae: Attini)
This paper describes a series of analyses of the separate and combined effects of components of micro-weather on foraging behaviour of leaf-cutting ants in Trinidad.

It is concluded that E. perplexa and A. hesperidum have kept CBF populations under effective biological control in Dominica and there is no evidence of any nontarget effects on other Aleyrodidae or their natural enemies.

Life History Parameters of the Leucaena Psyllid Heteropsylla Cubana (Crawford) (Homoptera: Psyllidae) under Various Temperature and Relative Humidity Regimes
The leucaena psyllid, Heteropsylla cubana, was studied under constant temperatures ranging from 21.5 to 35.0°C; females outlived males at all temperatures; age-specific life table statistics are given for the three temperatures.
IPM/ICM for vegetables and other crops in Antigua & Barbuda: status, potential and problems.
Biological control of the coconut whitefly, Aleurodicus pulvinatus, in Nevis.
The work provides a good model for other countries wishing to implement the Code of Conduct for the Import and Release of Exotic Biological Control Agents and offers a good case study of challenges/ problems in implementing this kind of project.
