“…The difference in the pattern of spatial dispersion of males and females observed in the present study agrees with results obtained using other conditions by Navarro & del Solar (1975). Social interactions between males, involving aggressive behaviour and territoriality, are described by Hoffmann (1987), and would be expected to lead to males being overdispersed.…”

Behavioural correlates of selection for oviposition by Drosophila melanogaster females in a patchy environment

The behaviour of females from lines selected for high (H) and low (L) aggregated oviposition was compared in an environment consisting of discrete patches of resource available for larval development. Oviposition behaviour was influenced by the conformation and by the texture of the substrate, but this does not account for the selective differences in levels of aggregation which are under genetic control. The distribution of males of both selected populations tends to be overdispersed across resource patches. This observation is consistent with male territorial behaviour. The dispersal patterns of females of the two selected populations differ significantly. H females show a contagious distribution whereas the distribution for L females is more nearly random. Differences in adult female dispersion are likely to be a significant factor contributing to aggregated oviposition. The level of aggregated oviposition affects the pattern of progeny survival when the unit of resource in each patch is small.

“…P:C 1:10 to P:C 10,000:1 over the course of 27 days, with P and C concentrations varying between 10 and 10,000 g l −1 (Matavelli et al, 2015). These nutritional modifications of food resources are likely favoured by the fact that females inoculate the fruit substrate with yeast during oviposition (Buser et al, 2014;Stamps et al, 2012) and tend to lay eggs in aggregations (Navarro and del Solar, 1975;Prokopy and Roitberg, 2001;Wertheim et al, 2005; see also experiment 2). In many cases, multiple fly species may also breed in the same fruits (Matavelli et al, 2015).…”

Animals, from insects to humans, select foods to regulate their acquisition of key nutrients in amounts and balances that maximise fitness. In species in which the nutrition of juveniles depends on parents, adults must make challenging foraging decisions that simultaneously address their own nutrient needs as well as those of their progeny. Here, we examined how the fruit fly Drosophila melanogaster, a species in which individuals eat and lay eggs in decaying fruits, integrate feeding decisions (individual nutrition) and oviposition decisions (offspring nutrition) when foraging. Using cafeteria assays with artificial diets varying in concentrations and ratios of protein to carbohydrates, we show that D. melanogaster females exhibit complex foraging patterns, alternating between laying eggs on high carbohydrate foods and feeding on foods with different nutrient contents depending on their own nutritional state. Although larvae showed faster development on high protein foods, both survival and learning performance were higher on balanced foods. We suggest that the apparent mismatch between the oviposition preference of females for high carbohydrate foods and the high performances of larvae on balanced foods reflects a natural situation where high carbohydrate ripened fruits gradually enrich in proteinaceous yeast as they start rotting, thereby yielding optimal nutrition for the developing larvae. Our findings that animals with rudimentary parental care uncouple feeding and egg-laying decisions in order to balance their own diet and provide a nutritionally optimal environment to their progeny reveal unsuspected levels of complexity in the nutritional ecology of parent-offspring interactions.

“…Drosophila is emerging as a powerful model for the study of the genetic basis of social behavior (Sokolowski 2010). Flies show a tendency to be attracted to one another and to congregate in all types of test chambers (Bolduc et al 2010; Lefranc et al 2001; Navarro & del Solar 1975). Importantly, increased proximity to conspecifics is required prior to other, more complex behaviors (Chen et al 2002; Connolly & Tully 1998).…”

We have established a new simple behavioral paradigm in Drosophila melanogaster to determine how genes and the environment influence the behavior of flies within a social group. Specifically, we measure social space as the distance between two flies. The majority of Canton-s flies, regardless of their gender, are within two-body lengths from each other. Their social experience affects this behavior, with social isolation reducing and mating enhancing social space respectively, in both males and females. Unlike several other social behaviors in the fly, including the formation of social groups themselves (a well described behavior - Bartelt et al., 1985, De Gee et al., 2008, Lof et al., 2008, Lof et al., 2009), social space does not require the perception of the previously identified aggregation pheromone cis-Vaccenyl Acetate (Bartelt et al., 1985). Conversely, performance of the assay in darkness or mutations in the eye pigmentation gene white increased social space. Our results establish a new assay for the genetic dissection of a fundamental mode of social interaction.
