WebJan 1, 2014 · Our results revealed that C. cunea possess a short-day induced larval diapause. The critical photoperiods for diapause induction in C. cunea were estimated … WebThe results show that temperature is the major diapause cue in the photoperiod-insensitive strain and the periods of middle fifth larval instar to early pupal stage are the thermal sensitive stages for pupal diapause induction with some different responses to temperatures between males and females in H. armigera.
WebMar 18, 2024 · The propensity of T. bourarachae to cold storage with and without diapause induction was studied. The effect of this technique on its emergence rate and parasitic activity was investigated. The study showed that wasps of T. bourarachae treated at the induction temperature of 15 °C for 5 days can be stored at 4 ± 1 °C for more than 30 … WebJan 25, 2024 · Some insect strains within a population may also be more sensitive than others to signals of diapause induction or termination (Roff & Bradford, 2000). For example, some individuals of Diabrotica barberi Smith & Lawrence, an important maize pest, express a prolonged diapause as an adaptation to the variability of crop cycles.

To complete the diapause determination, embryonic thermal information is stored for a long period (∼1 mo) until the middle pupal–adult development when it is finally transduced to the neuroendocrine DH …
WebJun 3, 2003 · Nezara viridula has an adult diapause controlled by a long-day photoperiodic response. At 20 °C and 25 °C in both sexes, photoperiodic responses were similar and had thresholds close to 12.5 h, thus suggesting that the response is thermostable within this range of temperatures and day-length plays a leading role in diapause induction.
Induction. The induction phase occurs at a genetically predetermined stage of life, and occurs well in advance of the environmental stress. This sensitive stage may occur within the lifetime of the diapausing individual, or in preceding generations, particularly in egg diapause.
