Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.

Codling Moth

The Codling Moth (Cydia pomonella) is a lepidopteran pest in the family Tortricidae, recognised globally as one of the most economically damaging insects affecting apple, pear, and walnut orchards. Adult moths have a wingspan of approximately 15–22 millimetres, with forewings patterned in grey and bronze, featuring a distinctive dark ocellate marking at the wing tip. Females lay eggs singly on fruit or foliage; hatching larvae bore directly into developing fruit, feeding on seeds and the core, creating characteristic brown frass-filled tunnels. By the time infestation is visible externally, significant damage to the crop has already occurred. Originally native to Eurasia, Cydia pomonella has established itself on every continent where pome fruits are cultivated, including North America, South America, South Africa, Australia, and New Zealand, facilitated by trade in infested plant material. Management relies on integrated approaches combining pheromone-based mating disruption, timed insecticide applications, kaolin clay barriers, and biological control using entomopathogenic nematodes and the granulovirus CpGV. Resistance to organophosphate and pyrethroid insecticides has developed in some populations, complicating conventional chemical management. The species undergoes 1–3 generations per year depending on climate. Despite its pest status, Cydia pomonella is not conservation-evaluated.
