“…Badyaev, 2002) and provides an explanation for our results. Another recent study on nine libelullids, which included territorial and non-territorial species, did not show sexual differences in egg size (Schenk & Söndgerath, 2005). This suggests that SSD in Odonata is not a consequence of differences in egg size but develops during larval development.…”

Abstract. Adult body size is the result of important environmental, maternal and/or genetic effects acting on animals during development. Here we investigate how sexual size dimorphism (SSD) develops in seven species of Odonata: Anax imperator, Cordulegaster boltonii, Onychogomphus uncatus, Oxygastra curtisii (Anisoptera), Cercion lindeni, Ischnura graellsii and Platycnemis acutipennis (Zygoptera). SSD of both the last larval and adult stages of the same individuals, which were reared under laboratory conditions, was measured. The aims were to investigate (i) whether SSD develops during the larval stage, (ii) the direction of larval and adult SSD, and (iii) whether the direction of adult SSD can be predicted by the mating system of a given species (e.g. males of territorial species being larger than females and the opposite for non-territorial species). We found that although larval differences in size may be present between the sexes, these are not necessarily shown in the adult stage (they may change or disappear). Also, the mating system was not related to patterns of adult SSD. Differences in SSD in larvae may be caused by differential use of resources via differential niche-utilisation or sex-specific growth patterns. We highlight the fact that sexual selection favouring large male size and fecundity selection, which selects for large females may be acting on the observed patterns in SSD in adults.

“…These findings suggest that eggs are qualitatively different depending on the timing of egg-laying. In some species, the duration of embryonic development is affected by egg volume (Gillooly and Dodson 2000a, b;Schenk and Söndgerath 2005). However, there is no evidence for this in burying beetles (Smiseth et al 2006 and this study).…”

In some species, a brood hatches or is born asynchronously over an extended period of time. This asynchronous hatching establishes competitive asymmetries between offspring, and younger offspring usually exhibit a higher mortality risk and/or lower growth rate. A large body of research suggests that selection favours asynchronous hatching, though a consensus is yet to be reached on the nature of its adaptive benefits. One of the possible causes of this is that previous studies have focused mostly on avian species, who must incubate their eggs. Thus, studying non-avian species may provide an opportunity to improve our understanding of the wider importance of asynchronous hatching, for example in invertebrates, which do not incubate their eggs. In the burying beetle, Nicrophorus quadripunctatus, asynchronous hatching has been shown to maximize parental fitness. However, there is currently no information on the proximate cause of asynchronous hatching in this species. Here we investigated the influence of timing of egg-laying and the duration of embryonic development on the timing of hatching. We found that the timing of egg-laying by the parent was a major determinant of the timing of hatching, although the duration of embryonic development was also important. Our results suggest that the principal proximate cause of asynchronous hatching is parental asynchronous egg-laying.

“…Geralmente, as dietas artificiais nas quais as moscas-dasfrutas são criadas apresentam conteúdo protéico-calórico mais elevado que os frutos, seu alimento natural (JoachimBravo & Zucoloto 1998). Sabe-se também que o tamanho dos ovos produzidos por insetos varia, entre outros fatores, com a alimentação dos mesmos (Bauerfeind & Fischer 2005, Moreau et al 2007, e que o tamanho dos ovos influencia a performance dos imaturos (Schenk & Sondgerath 2005, Fox & Czesak 2006. Assim, com relação aos resultados aqui obtidos, a qualidade dos ovos da população mantida em dieta (Lab-pop) poderia explicar a sobrevivência dos imaturos em laranja.…”

-This study evaluated the influence of two fruits hosts (orange and papaya) on biological and behavioral parameters of two populations of Ceratitis capitata (Wiedemann) reared under laboratory conditions. One of these populations has been reared under laboratory conditions by 25 years without introduction of wild flies (Lab-pop), while the other has been maintained under the same conditions by 15 years but with occasional introduction of wild specimens (Hybrid-pop). The following parameters were analyzed: emergence percentage, life cycle duration (from eclosion to emergence), adult size, longevity, female fecundity and oviposition preference. The best performance of immatures of both populations was obtained on papaya as a host. Larvae reared on orange had longer life cycle, low emergence percentage and smaller adults. The fruit type did not affect fecundity and longevity of the Lab-pop, but in the Hybrid-pop males lived longer when reared on papaya, while females had higher longevity and fecundity when reared on orange. Females of both populations preferred to lay eggs in papaya (better host for larvae) when compared to orange. However, some eggs were deposited on orange only by females of Lab-pop, suggesting a lower ability for host selection of this population. These data are discussed regarding to the effects of continuous laboratory rearing on the biological parameters of this species.
