Diapause induction as an interplay between seasonal token stimuli, and modifying and directly limiting factors: hibernation in Chymomyza costata

Popis výsledku v původním jazyce

Larvae of wild type (WT) strain of /Chymomyza costata/ enter diapause (stop developing) in response to short day signal at constant 18°C, while larvae of non-photoperiodic (NPD) strain do not respond to photoperiodic signalling and continue in development irrespective of daylength. Here we describe that WT larvae responded reliably also to thermoperiodic signal (daily cycles of temperature) under constant darkness, while the NPD larvae did not. Temperature and larval population density modified the output of token stimuli signalling. Overcrowding lengthened the larval development and induced a diapause-like’ developmental arrest of relatively weak intensity in up to 60% of larvae of both strains. Starvation blocked development and caused mortality when applied in larvae younger than day 3 of 3rd instar. Collectively, we showed that diapause induction in /C. costata/ is a result of variously interacting effects of multiple environmental factors.
