Extended life cycle in the chestnut weevil: prolonged or repeated diapause?
Entomologia Experimentalis et Applicata, 2005AbstractMany insect species extend the life cycle of a part of their population over several years. The adaptive value of these long cycles is now well documented, but the physiological processes underlying them have been little studied. Long life cycles are usually viewed as resulting from prolonged diapause proceeding from a simple extension of the ...

Abstract Nutrient metabolism is crucial for the survival of insects through the diapause. However, little is known about the metabolic mechanism of prolonged diapause. The sawfly, Cephalcia chuxiongica (Hymenoptera: Pamphiliidae), is a notorious defoliator of pine trees in southwest China.

Dynamic complexities in a hyperparasitic system with prolonged diapause for host
Chaos, Solitons & Fractals, 2009Abstract In this paper, a hyperparasitic system with prolonged diapause for host is proposed and analyzed. For the biologically reasonable range of parameter values, the global dynamics of the system has been studied numerically. Especially, the effect of prolonged diapause and hyperparasitism on the system is investigated.

Curculio sikkimensis undergoes prolonged larval diapause that is terminated by chilling and warming cycles. To examine the effects of warming temperatures and their duration on diapause termination, we exposed diapause larvae that had not been reactivated after chilling at 5 degrees C to 20 or 25 degrees C and chilled them again before incubation at 20

The chestnut weevil Curculio sikkimensis undergoes a prolonged larval diapause that is completed by repeated exposure to chilling and warming. We examined the possible reversibility of diapause intensity in response to temperature changes. All larvae were subjected to an initial chilling followed by incubation at 20°C to force pupation of the 1-year ...

The lizard Calotes versicolor delays oviposition of oviductal eggs for as long as 6 months or more under unfavourable conditions. During this period of prolonged egg retention, the growth of oviductal embryos is arrested at stage 34. The present study shows for the first time among reptiles that the "embryonic diapause" is manifested by the gravid ...

Quercus crispula (= Q. mongolica var. grosseserrata) is the predominant tree species in cool temperate, mixed broadleaf/conifer forests in northern Japan. We compared 11 years of data on acorn production in a population of Q. crispula, with data on seed-insect populations, to try to answer the following questions: (1) Does Q.
