“…The same pattern has been reported for the fruit fl y R. cerasi, in which there is a tradeoff between prolonged diapause and lifetime fecundity and oviposition (Moraiti et al, 2012). We did not weigh the pupae and therefore do not know whether there is a relation between prolonged diapause and pupal weight.…”

“…All these traits are associated with potential fitness trade-offs [32]. In some insect species, this fitness trade-off is counterbalanced by increased body size of those individuals undergoing dormancy [33]. For butterflies, the role that body size plays in the relationship between dormancy, life span and fecundity has as yet been studied only scarcely in temperate regions [34], most work that has been done so far is on tropical species, e.g.…”

What Prolongs a Butterfly's Life?: Trade-Offs between Dormancy, Fecundity and Body Size

2014

In butterflies, life span often increases only at the expense of fecundity. Prolonged life span, on the other hand, provides more opportunities for oviposition. Here, we studied the association between life span and summer dormancy in two closely related species of Palearctic Meadow Brown butterflies, the endemic Maniola nurag and the widespread M. jurtina, from two climatic provenances, a Mediterranean and a Central European site, and tested the relationships between longevity, body size and fecundity. We experimentally induced summer dormancy and hence prolonged the butterflies’ life in order to study the effects of such a prolonged life. We were able to modulate longevity only in Mediterranean females by rearing them under summer photoperiodic conditions (light 16 h : dark 8 h), thereby more than doubling their natural life span, to up to 246 days. Central European individuals kept their natural average live span under all treatments, as did Mediterranean individuals under autumn treatment (light 11: dark 13). Body size only had a significant effect in the smaller species, M. nurag, where it affected the duration of dormancy and lifetime fecundity. In the larger species, M. jurtina, a prolonged adult life span did, surprisingly, not convey any fecundity loss. In M. nurag, which generally deposited fewer eggs, extended life had a fecundity cost. We conclude that Mediterranen M. jurtina butterflies have an extraordinary plasticity in aging which allows them to extend life span in response to adverse environmental conditions and relieve the time limitation on egg-laying while maintaining egg production at equal levels.

“…The interplay between host plant phenology and cyclical insect seasonal activity patterns has been studied for many different species (Coyle et al 2010, Gerling et al 2011, Sadakiyo and Ishihara 2011, Moraiti et al 2012. Olive fruit ßy reproductive phenology, at least as measured by male response to female sex pheromones, is not closely linked to the seasonality of its host, the European olive.…”

Seasonal Pheromone Trap Catches of Male <I>Bactrocera oleae</I> (Diptera: Tephritidae) in Northern California: Asynchrony With Host (Olive Tree) Phenology?

Bactrocera oleae (Rossi) (Diptera: Tephritidae, Dacinae) is an oligophagous species that feeds only on cultivated olives (Olea europaea L.) and its close relatives. Synchrony of seasonal activity patterns of B. oleae, the olive fruit fly with its host's phenology is therefore expected. The objective of this study was to monitor the male olive fruit fly response to female sex pheromone in the field. White sticky traps were deployed year round for 3 yr in an olive orchard in Oroville, CA. They were checked periodically, and flies captured were counted and sexed. Although males were captured regularly, the numbers of females captured on pheromone traps were negligible. Food-baited traps and water-baited traps were deployed to show the presence of flies in the field. Our hypothesis that males would respond to pheromone when females were available and olive fruits were susceptible for oviposition was partially supported. There were two peaks of high male captures in pheromone traps: spring and fall. In spring, females were available and mature but few acceptable olives were available for oviposition (no new crop olives yet). In fall, females were present but many of the new crop olives were already infested. The food baited traps confirmed the presence of flies in the field even when very few were being captured in the pheromone-baited traps. Traps containing only water caught only two flies showing that water alone or the trap type in itself was not attractive to flies.
