“…Moreover, our results show that both sexes are equally strongly negatively affected by artificial light (in contrast to [5]). Reduced feeding of both females and males owing to artificial light, especially rich in short wavelength radiation (green treatment), results in shorter longevity [16,17] and subsequently a shorter effective reproduction period. Moreover, it results in reduced fertility, e.g.…”

One major, yet poorly studied, change in the environment is nocturnal light pollution, which strongly alters habitats of nocturnally active species. Artificial night lighting is often considered as driving force behind rapid moth population declines in severely illuminated countries. To understand these declines, the question remains whether artificial light causes only increased mortality or also sublethal effects. We show that moths subjected to artificial night lighting spend less time feeding than moths in darkness, with the shortest time under light conditions rich in short wavelength radiation. These findings provide evidence for sublethal effects contributing to moth population declines. Because effects are strong under various types of light compared with dark conditions, the potential of spectral alterations as a conservation tool may be overestimated. Therefore, restoration and maintenance of darkness in illuminated areas is essential for reversing declines of moth populations.

“…starved females of Cydia pomonella (Tortricidae) laid fewer eggs than fed females [18]. Also sex pheromone production in Heliothis virescens (Noctuidae) [19] and duration of pheromone excretion in Spodoptera littoralis (Noctuidae) [17] reduces when females feed less. Therefore, fewer males will be attracted for mating.…”

“…Two factors may have negatively affected female reproductive output: (1) the cost of repeated pheromone production in consecutive evenings, before attracting a male; (2) mating, and thus ovipositing, at a relatively old age. The cost of pheromone production has been demonstrated directly for the burying beetle Nicrophorus vespilloides and indirectly for the pink bollworm Pectinophora gossypiella .…”
