Figure 2 in Oviposition preference and larval performance in a Heliconius erato phyllis (Lepidoptera: Nymphalidae) population from southeastern Brazil: is there a positive relationship?
Figure 2. Influence of larval host plant species on (A) Head capsule width (fourth instar larvae); (B) larval development time; (C) forewing length; (D) survival (proportion of individuals that reached the adult stage) of Heliconius erato phyllis reared in the laboratory under controlled conditions. Data are presented as median ± interquartiles (A, B), mean ± standard error (C) and percentages (D). For each trait, different letters above bars indicate significant differences among host plants (Dunn's multiple comparison tests for A and B, and Tukey's multiple comparison tests for C).

Data from: Oviposition preference of cabbage white butterflies in the framework of costs and benefits of interspecific herbivore associations
When deciding where to oviposit, herbivorous insects consider: (i) the plant's value as a food source, (ii) the risks of competing with con- and heterospecific herbivores, and (iii) the risks of parasitism and predation on the host plant. The presence of con- and/or heterospecific competitors would further affect the oviposition preference, because the preceding herbivores induce direct/indirect defences in plants against forthcoming herbivores, and thereby alter oviposition decisions. In previous studies, the abovementioned factors have not been studied in an integrative manner. We performed here a case study of this by assessing the oviposition preferences of a small white butterfly, Pieris rapae, for plants occupied by combinations of conspecific larvae, heterospecific larvae (Plutella xylostella), specialist parasitoids of Pi. rapae (Cotesia glomerata) and generalist predators (ants). We previously reported that the females showed equal preference for Pl. xylostella-infested and uninfested plants. Here, we showed that Pi. rapae females preferred uninfested plants to conspecific-infested ones, and Pl. xylostella-infested plants to Pi. rapae-infested ones. We discuss these oviposition preferences of Pi. rapae females in the framework of costs and benefits of interspecific herbivore associations from the above point of view.
Data from: Differences in larval nutritional requirements and female oviposition preference reflect the order of fruit colonization of Zaprionus indianus and Drosophila simulans
Species coexist using the same nutritional resource by partitioning it either in space or time, but few studies explore how species-specific nutritional requirements allow partitioning. Zaprionus indianus and Drosophila simulans co-exist in figs by invading the fruit at different stages; Z. indianus colonizes ripe figs, whereas D. simulans oviposits in decaying fruit. Larvae feed on yeast growing on the fruit, which serves as their primary protein source. Because yeast populations increase as fruit decays, we find that ripe fruit has lower protein content than rotting fruit. Therefore, we hypothesized that Z. indianus and D. simulans larvae differ in their dietary requirements for protein. We used nutritional geometry to assess the effects of protein and carbohydrate concentration in the larval diet on life history characters in both species. Survival, development time, and ovariole number respond differently to the composition of the larval diet, with Z. indianus generally performing better across a wider range of protein concentrations. Correspondingly, we found that Z. indianus females preferred to lay eggs on low protein foods, while D. simulans females chose higher protein foods for oviposition when competing with Z. indianus. We propose the different nutritional requirements and oviposition preference of these two species allows them to temporally partition their habitat.

Data for: Temperature-mediated male condition shapes female fitness and oviposition preference in a butterfly
<p class="CxSpFirst">Habitat choice by ovipositing females critically shapes fitness in species lacking parental care. We aimed at manipulating female oviposition choosiness using the Glanville fritillary butterfly (<i>Melitaea cinxia</i>) as study species. We tested whether female choosiness is influenced by individual condition and/or that of the mating partner, which was manipulated experimentally by subjecting adults to night temperatures warmer than usual. Against our prediction, female life expectancy was not altered by the treatment and impacted her fitness only mildly. Males exposed to warm nights, on the other hand, lived shorter and females who mated with warm-exposed males sired larger clutches with higher hatching success, in line with the terminal investment hypothesis. We also tested whether females base their oviposition choices primarily on habitat type (open/shaded) or plant condition (dry/well-watered) under a semi-natural experimental set-up. We show that females choose primarily open habitats and within those habitats well-watered host plants. While female choosiness for oviposition was not affected by their own thermal treatment, mating with warm-exposed males also strengthened the female oviposition preference towards the generally preferred host plant species in this study (<i>Plantago lanceolata</i>). The present work brings new awareness on the often-neglected role of male condition in shaping female fitness and choice.</p>

The legend of expected corresponds to the number of clutches that would be expected to find in relation to the availability of the substrate in the entire study area. The category 'others' refers to other types of leaves present in the area.
