: In recent years, there have been numerousreports of species of invasive predatory flatworms(Geoplanidae) across several islands of the Caribbean.Terrestrial planarians and their cocoons are believed tobe dispersed to new territories mainly through planttrades; the worms/cocoons may be accidentallytransmitted in the soil of potted plants or within thefoliage. The exotic terrestrial flatworm, Bipaliumkewense, was first reported in Jamaica in 1897 [1]. Later,the suspected sightings of Platydemus manokwari andBipalium vagum [2] were documented, in 2019 and 2020,respectively. Terrestrial flatworms were collected as partof a wider study of the epidemiology and transmission ofzoonotic parasite, Angiostrongylus cantonensis, inJamaica.
Pesticide usage in agriculture has occurred for centuries and led to significant positive outcomes in food production and noticeable reduction in crop losses. However, pesticide usage on food crops often results in the presence of toxic pesticide residues on food produce, which is the main route of exposure to pesticides in humans. The toxicity of the pesticide residues can potentially cause debilitating effects to major human organs and body systems. Pesticide residue analysis addresses the issue of pesticide residues in foods by screening and quantifying the levels of pesticides in food commodities.
Numerous organic chemicals, either directly manufactured or formed as byproducts of other processes, are released into the environment. Once there, many cause adverse effects on environmental and human systems. Of particular concern are long-lasting impacts from those organic pollutants that remain in the environment for long periods of time. The development of appropriate management strategies to address this problem requires knowledge of the environmental distributions of these pollutants.
The global essential oils market has been estimated to be US$10.6b in 2021 rising to US$16.0b in 2026 [(Markets, 2021)1] as a result of growth in awareness to preventative healthcare, improvements in the standard of living, along with an increase in the demand for aromatherapy products. With the potential availability of relevant plant materials in Tobago, it is appropriate to develop a strategy for the introduction of Plant Extracts Industry in the island.
Vector-borne diseases have since the 17th century been the leading cause of death by disease more than any other causes combined, even preventing development in the tropics (Gubler 1998). Of all insect vectors, Aedes aegypti proves to be the deadliest as it is the primary vector of the four most notorious vector-borne diseases – chikungunya (chik-V), Zika (Zik-V), dengue fever and yellow fever viruses. Control of the spread of Aedesborne diseases is primarily reliant on the control of the vector responsible for their spread. Traditionally, vector control relied on environmental hygiene and the elimination of breeding sites (Gubler 1998), shifting only in the 1980s to the use of synthetic chemicals in the form of carbamate, organochloride, organophosphate and pyrethroid insecticides (Norris, et al. 2015). However, the evolution of Aedes aegypti resistance to synthetic chemicals have made control of the spread of the vector and its diseases increasingly difficult. This led to the exploration of innovative and alternative methods in the control of Aedes aegypti.
