WebFeb 15, 2024 · The induction of diapause represents a dramatic change in the normal progression of age. Hormones such as juvenile hormone, 20-hydroxyecdysone, and prothoracicotropic hormone are well-known to modulate this plasticity. The induction of diapause—and by extension, the cessation of normal aging—is coordinated by … WebFeb 3, 2012 · Diapause is a developmental arrest that allows an organism to survive unfavorable environmental conditions and is induced by environmental signals at a certain sensitive developmental stage. In Helicoverpa armigera, the larval brain receives the environmental signals for diapause induction and then regulates diapause entry at the …
WebJul 20, 2016 · High temperatures (>24 °C) tend to avert, whereas low temperatures (<18 °C), especially in combination with constant darkness, stimulate diapause induction in WT strain. Overcrowding (>200 larvae per 5 g of larval diet) lengthens the duration of larval development and induces a ‘diapause-like’ developmental arrest of relatively weak ...

WebRESULTS Like in other insects, the absence of JH triggers the induction and maintenance of reproductive diapause in H. axyridis, indicated by JH measurements and the knockdown of an intracellular JH receptor Methoprene-tolerant (Met). Methoprene, a JH analog, significantly reversed diapause into reproduction via Met. WebThe rice stem borer, Chilo suppressalis, enters facultative diapause as fully grown larvae in response to short-day conditions during the autumn. Our results showed that the critical night length for diapause induction in C. suppressalis was between 10 h 22 min and 10h 45 min at 22, 25 and 28 degrees C, 11 h 18 min at 31 degrees C, and between ...
WebDiapause induction and termination responses of a northern strain (Minnesota [MN]) of Ostrinia nubilalis were compared with those of a southern strain (Georgia [GA]). A thermoperiod in constant light (12 hr at 25 degrees C alternating with 12 hr at 4 degrees C) failed to induce diapause in GA larvae, but approximately 50% diapause induction was ...
