“…The findings of other authors also indicated that animals try to cross matrix relatively quickly (Miyatake et al 1995;Schultz 1998;Conradt and Roper 2006;Schtickzelle et al 2007;Schultz et al 2012). However, moving through matrix may be associated with lower supply of resources, higher mortality due to predation, and low probability of finding another habitat patch (Rankin and Burchsted 1992;Zollner and Lima 1999;Schtickzelle and Baguette 2003;Stamps et al 2005;Schtickzelle et al 2007). Therefore, in order to facilitate movements of P. teleius through matrix the corridors of low quality may be a useful solution.…”

Understanding individual movements in heterogeneous environments is central to predicting how landscape changes affect animal populations. An important but poorly understood phenomenon is behavioural response to habitat boundaries and the way animals cross inhospitable matrix surrounding habitat patches. Here, we analyze movement decisions, flight behaviour, and activity of the endangered scarce large blue Phengaris (Maculinea) teleius, focusing on the differences among the patterns observed in patch interior, at patch boundaries and within matrix. The probability of crossing an external patch boundary, regardless of the land use in the adjacent area, was considerably lower than crossing a 'control line' within patch interior. Movement distances, flight durations and net squared displacement were largest in matrix, while similarly smaller at patch boundaries and in patch interior. The distribution of angles between successive movements was clearly clustered around 0°(indicating flight in a straight line) in matrix and at patch boundaries, but not in patch interior. There were no differences in time spent on foraging, resting and ovipositing between patch interior and boundaries, but the first two activities rarely, and oviposition never, happened in matrix. Our results suggest that although P. teleius adults do not avoid using the resources located in the boundaries of habitat patches, they often return to the interior of the patches when crossing their boundaries. However, having entered the matrix the butterflies perform relatively long and straight flights. The estimated probability of emigration and net squared distance implies that the dispersal between local populations is common in this species in the studied area.

“…Reduced body size and fecundity, and increased longevity and pre-ovipositional period have been also associated to unfavorable environments and migration in P. xylostella (Hillyer & Thorsteinson 1971, Pivnick et al 1990, Branco & Gatehouse 1999, Campos et al 2004. Although the relationship between intraspecifi c body size variation and migration is controversial (Rankin & Burchsted 1992), some authors have inferred that the smaller the individuals of P. xylostella, the more active migrants they are (Pittendrigh & Pivnick 1993;Muhamad et al 1994;Begun et al 1996Begun et al , 1997Campos et al 2004). None of these phenotypic variables responded to experimentally manipulated photoperiod (Tables 1, 2), and females started laying eggs a day after emergence.…”

Fotoperiodismo e Sazonalidade em População Neotropical de Plutella xylostella L. (Lepidoptera:Yponomeutidae)RESUMO -Populações neotropicais de Plutella xylostella L. possuem ciclos sazonais de crescimento e declíneo e a migração é um fator-chave na geração da dinâmica populacional. Devido à previsibilidade sazonal das oscilações populacionais, o fotoperíodo poderia agir como o sinal que desencadea o comportamento migratório do inseto. Migrações de insetos são geralmente precedidas por diapausa reprodutiva, uma típica resposta fotoperiódica caracterizada por alterações morfológicas, fi siológicas e comportamentais que possibilitam discriminar as formas migratórias das não-migratórias. Neste estudo, foi testado se o desenvolvimento pré-imaginal e reprodutivo de P. xylostella, proveniente de Minas Gerais, é inibido por fotoperíodos equivalentes aos comprimentos de dias em que ocorrem as fases de crescimento ou de declínio das populações naturais. Nenhuma evidencia de resposta fotoperiódica foi encontrada para os insetos criados em laboratório sob cinco regimes constantes de fotoperíodos, variando de oito a dezesseis horas-luz-dia. Não houve variação signifi cativa na sobrevivência e na duração dos estágios de ovo, larva e pupa. O peso das pupas também não foi afetado, assim como o tamanho, a fecundidade e a longevidade dos adultos. Embora algumas espécies de insetos possuam respostas fotoperiódicas geografi camente diferenciadas, a sugestão de alguns autores de que a cosmopolita P. xylostella responde ao fotoperíodo em regiões de clima temperado foi questionada. Os dados experimentais não suportaram a hipótese de que a sazonalidade migratória e populacional de P. xylostella dependem do fotoperíodo como sinal de anúncio de mudanças temporais na qualidade do habitat.PALAVRAS-CHAVE: Diapausa, dinâmica populacional, fotoperíodo, migração ABSTRACT -Neotropical populations of the diamondback moth Plutella xylostella L. have seasonal cycles of growth and decrease, and moth migration plays a fundamental role in generating such population dynamics. Since the oscillation of these populations is predictable, photoperiod might operate as a signal that triggers the migratory behaviour of the insect. Migration in insects is usually preceded by reproductive diapause, a photoperiodic response that can be characterised by morphological, physiological and behavioural alterations that permit to discriminate between migratory and nonmigratory forms. In this study, I tested whether the pre-imaginal and reproductive development of P. xylostella from Minas Gerais (Brazil) is affected by artifi cial day-lengths that are equivalent to the periods of natural population growth or decrease. No evidence of photoperiodic response was found for the insect reared in laboratory on fi ve different constant photoperiods, from 8h to 16h of light per day. There was no signifi cant variation in survival and duration of egg, larva, and pupa stages or in pupal weight, adult size (forewing length), fecundity, and longevity. Although some species have geog...

“…It is presumed to be a costly behavior, with adult reproduction suffering a trade-off in energy needed for adult flight apparatus construction and flight fuel versus ovarian development, or oogenesis (Rankin and Burchsted, 1992;Crowley and McLetchie, 2002;Ronce, 2007). The cost is usually manifested, especially in wing dimorphic species, as decreased reproductive output caused by a prolonged pre-oviposition period, decreased longevity, and decreased lifetime egg production (Dingle and Arora, 1973;Walters and Dixon, 1983;Roff, 1984;Zera, 1984;Zera and Mole, 1994).…”

The beet armyworm, Spodoptera exigua, undertakes long-distance migration. We used flight mills to investigate the interaction between flight and reproduction in this species given the apparent absence of the oogenesis-flight syndrome. This syndrome, common in many migratory insects, is characterized by a suite of traits including migration during the pre-oviposition period followed by a switch to oogenesis. No negative effects of inter-ovipositional flight on lifetime fecundity were observed. Instead, adult reproductive output suffered when female flight was initiated the first day after eclosion and before oviposition, suggesting that migratory flight overlaps with the oviposition period rather than being confined to the pre-oviposition period. Mating status of both females and males had no negative influence on their flight performance except that flight distance and flight duration of 7-day-old mated females were significantly less than in unmated females. Furthermore, the number of eggs produced and mating frequency of females less than 7 days of age were not significantly correlated with flight performance, suggesting reproductive development paralleled and was independent of migratory behavior. This independent relationship between flight and reproduction of adults is consistent with the very short pre-oviposition period in this species, and suggests that resources are partitioned between these activities during pupal development. Together, our results uncovered neither obvious trade-offs nor mutual suppression between flight and reproduction in S. exigua, which indicates the lack of an oogenesis-flight syndrome for coordination of these two energy-intensive processes. We propose a conceptual model of migration for this species based on the current and previous studies.
