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.

common bubble snail

The common bubble snail (<em>Akera bullata</em>) is a marine gastropod mollusc found in the coastal waters of Denmark, Norway, Portugal, and Sweden. This species typically inhabits terrestrial and aquatic environments including forests and freshwater-adjacent marine areas, often occurring in shallow subtidal and intertidal zones of temperate European seas. It is classified as Least Concern on the IUCN Red List. As a member of the family Akeridae, the common bubble snail is characterized by its thin, fragile shell and its ability to swim briefly by flapping its large, wing-like parapodia. The species often forages on algae and detritus in sandy and muddy seafloor habitats, particularly in sheltered bays and estuaries. The common bubble snail typically aggregates in large numbers during the spawning season, producing gelatinous egg masses. Biological traits of this species remain poorly documented in the scientific literature.
