Diapause induction
WebApr 13, 2024 · Temperature and photoperiodic-dependent diapause induction are different between the Kosetsu strain of B. mori and the Fuchu population of B. mandarina. We first confirmed the photoperiodic response in diapause induction of B. mandarina as described previously 27.When eggs were incubated under 25DD during embryonic development, … WebJan 1, 2024 · Abstract. The onion maggot, Delia antiqua, is a worldwide subterranean pest and can enter diapause during the summer and winter seasons.The molecular regulation of the ontogenesis transition remains largely unknown.

WebIn most cases, the diapause incidence predicted by the model was within or close to the 95% confidence interval estimated from independently observed field data. … WebNo sensitive instar was identified for diapause induction under alternated short- (L : D 11 : 13 h) and long-day (L : D 14 : 10 h) treatments at different larval stages. However, accumulative treatment of three instars and 10 d under short-day treatment was required for the induction of 50% larval diapause. All larvae entered diapause at 20°C ...
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 … WebDiapause is an endocrine-mediated metabolic and developmental arrest induced by changes in abiotic cues that indicate the onset of adverse environmental conditions.10 …
WebJan 30, 2015 · To investigate the molecular mechanisms underlying diapause induction, we used custom whole transcriptome microarrays to identify differences in gene expression following exposure to nondiapause (long days, 25 °C) and diapause-inducing (short days, 18 °C) environmental conditions. Using a two-way ANOVA, we identified 1130 genes that … WebSep 7, 2024 · In the present study, diapause induction of P. interpunctella was systematically investigated under laboratory conditions, at a constant low temperature …
