TLDR
Individual female Episyrphus balteatus (DeGeer) (Diptera: Syrphidae) show different oviposition preferences when presented with two aphid prey species, suggesting that natural selection has responded to the nutritional value of prey.Abstract:
Individual female Episyrphus balteatus (DeGeer) (Diptera: Syrphidae) show different oviposition preferences when presented with two aphid prey species, Aphis sambuci L. and A. fabae (Scop). After larvae were reared on those aphids, some fitness components indicated that individual females were adapted to different host-use strategies, with preference for one aphid prey species entailing a trade-off in poorer performance on another. We interpret the pattern of significant interactions as suggesting that natural selection has responded to the nutritional value of prey.read more

Putting Eggs in One Basket: Ecological and Evolutionary Hypotheses for Variation in Oviposition-Site Choice
TL;DR: This work presents six hypotheses that have been used to explain nonrandom oviposition-site choice in insects, fish, amphibians, reptiles, and birds: maximizing embryo survival, maximizing maternal survival, modifying offspring phenotype, proximity to suitable habitat for offspring, and maintaining natal philopatry.

Optimization of adult performance determines host choice in a grass miner.
TL;DR: It is shown, for the first time, that adult feeding site and related adult performance may explain most of the variation in adult feeding and oviposition site selection of an oligophagous grass miner, Chromatomyia nigra (Diptera).

Impact of nest-site selection on nest success and nest temperature in natural and disturbed habitats
Jason J. Kolbe,Fredric J. Janzen +1 more
TL;DR: The importance of nest-site selection as a substantive maternal effect, understanding habitat use during crucial life-history events, and the potential for human disturbance to modify offspring phenotypes and negatively impact nest success despite adaptive nesting behavior are illustrated.

Reproductive timing and individual fitness
TL;DR: It is suggested that the ultimate test on the applicability of λind vs. LRS as practical measures of individual fitness in quantifying selection should come from studies which correlate these estimates with actual number of descendants left more than one generation further in future.

TL;DR: The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book.

The Coevolutionary Process
TL;DR: The geographic mosaic theory of coevolution was proposed by Thompson as discussed by the authors to understand the development of reciprocal adaptations and specializations in interdependent species, using examples of species interaction from a range of taxa.

Evolutionary ecology of the relationship between oviposition preference and performance of offspring in phytophagous insects
TL;DR: Understanding of the relationships between oviposition preference and growth, survival, and reproduction of offspring is hampered by an almost complete lack of data on how preference and performance are related genetically.
