Carpocapse des châtaignes

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.

Roussette de Livingstone

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
