Science and technology and its application to regional development
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.
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.
Invasive alien species (IAS) are implicated in the extinction or decline of numerous native aquatic species worldwide. Their negative impacts occur through mechanisms including habitat alteration, competition, predation, hybridisation, and the spread of disease (Strayer et al. 2006). Small island ecosystems are most susceptible to the impacts of IAS. Once established, freshwater IAS are difficult to eradicate without negatively impacting native species.
At the inception of automated solar tracking in the 1970’s, geometric architectures with pair(/s) of solid-state photo-sensitive devices were constructed and used to detect the sun’s position. As an alternative in recent years, cameras have been used to capture and process live sky images to detect the sun’s position. When the sky is cloudy however, both approaches are prone to errors and sometimes require human intervention which tend to reduce the trackers’ economic viability [1].
Plant viruses are responsible for significant losses in crop production annually. Infections are often exacerbated by mixed infections. One strategy of combatting viral disease spread lies in swift diagnoses so that immediate interventions can be employed to slow or stop their spread. Sweet pepper, hot pepper, and tomato are among the most important cash crops in Jamaica and are constantly threatened by pathogens.
