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.

Red-billed Duck

Red-billed Duck (Anas erythrorhyncha) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.
