“…Oogenesis is a continuous and short process in the pollen beetle, approximately 2 days (Nilsson 1988a;Hopkins andEkbom 1996, 1999;Ekbom and Ferdinand 2003;Ekbom and Popov 2004). This means that the same host plant is used both to feed and to oviposit, and Hervé et al (2014b) proved a direct relationship between the two processes.…”

International audienceBreeding for plant resistance to insect pests is a classic strategy in integrated management, but it has never been developed for use against European pests of oilseed rape (Brassica napus) (OSR), especially one of the most damaging ones, the pollen beetle (Meligethes aeneus). In this paper we look at the three strategies that could be employed to improve OSR resistance (based on transgenes, relatives of B. napus or OSR natural variation) and review our current knowledge as to how these strategies could be put into practice. We identify the drawbacks which are specific to the pollen beetle that could impede breeding programs for resistance, and propose an approach to circumvent them. Finally, we detail the steps of the interaction between OSR and the pollen beetle that could be targeted in order to improve plant resistance (host plant location, adult survival, adult feeding, egg production and oviposition, larval development) and discuss their efficiency and durability potential

“…However, there is growing evidence that, although female oviposition decisions are made to maximize their net fitness, female decisions may not match maximal performance of some or any offspring (Mayhew 1997). For example, females may produce a large number of low quality offspring by increased oviposition in high-quality resources (Nufio and Papaj 2004) or females may allocate their investment differently over offspring to match resource quality (Ekbom and Popov 2004). Furthermore, these decisions might look suboptimal when not considered in the total reproductive strategy.…”

Species utilizing distinct resources for offspring production often show plasticity in reproductive strategies as a function of resource quality. For species using ephemeral pools, strategies are mainly shaped by a time constraint related to pool stability, resource availability and the colonizing community. We studied reproductive strategies in Amazonian poison frogs (Dendrobates ventrimaculatus) that are characterized by oviposition in distinct, small and resource-limited water bodies in leaf axils of plants and the transport of newly hatched tadpoles on the back of males to similar water bodies. Cannibalism of eggs by tadpoles was found to be the main cause of egg mortality. Typically, at the end of the rainy season new clutches of eggs were deposited in water bodies already containing a tadpole. Manipulation of the available number of water bodies showed that this observation did not result from resource limitation. We conclude that D. ventrimaculatus has a plastic reproductive strategy that includes provisioning its tadpoles with fertilized eggs as a function of desiccation risk of water bodies housing its offspring. Provisioning behavior is expected to increase developmental rate and, therefore, chances of metamorphosis for tadpoles that hatched towards the end of the rainy season. The plastic food provisioning strategy may be an important evolutionary link to bi-parental and female care with development of obligate unfertilized egg provisioning in the genus Dendrobates.

“…Within the Coleoptera and Lepidoptera there are a number of species that exhibit egg size plasticity in response to host species and/or quality (Leather and Burnand 1987;Nylin and Gotthard 1998;Awmack and Leather 2002;Ekbom and Popov 2004;Takakura 2004). Plastic responses to host quality, like the responses we observed in S. limbatus, are a strategy that allows organisms to cope with variation among hosts.…”

Population differences in host use by a seed-beetle: local adaptation, phenotypic plasticity and maternal effects

For insects that develop inside discrete hosts, both host size and host quality constrain offspring growth, influencing the evolution of body size and life history traits. Using a two-generation common garden experiment, we quantified the contribution of maternal and rearing hosts to differences in growth and life history traits between populations of the seed-feeding beetle Stator limbatus that use a large-seeded host, Acacia greggii, and a small-seeded host, Pseudosamanea guachapele. Populations differed genetically for all traits when beetles were raised in a common garden. Contrary to expectations from the local adaptation hypothesis, beetles from all populations were larger, developed faster and had higher survivorship when reared on seeds of A. greggii (the larger host), irrespective of their native host. We observed two host plant-mediated maternal effects: offspring matured sooner, regardless of their rearing host, when their mothers were reared on P. guachapele (this was not caused by an effect of rearing host on egg size), and females laid larger eggs on P. guachapele. This is the first study to document plasticity by S. limbatus in response to P. guachapele, suggesting that plasticity is an ancestral trait in S. limbatus that likely plays an important role in diet expansion. Although differences between populations in growth and life history traits are likely adaptations to their host plants, host-associated maternal effects, partly mediated by maternal egg size plasticity, influence growth and life history traits and likely play an important role in the evolution of the breadth of S. limbatus' diet. More generally, phenotypic plasticity mediates the fitness consequences of using novel hosts, likely facilitating colonization of new hosts, but also buffering herbivores from selection post-colonization. Plasticity in response to novel versus normal hosts varied among our study populations such that disentangling the historical role of plasticity in mediating diet evolution requires the consideration of evolutionary history.
