Very little is known about the genetic basis of behavioral variation in courtship behavior in Hymenoptera, which can contribute to speciation by prezygotic isolation of closely related species. Here, we analyze the genetic basis and architecture of species differences in the male courtship behavior of two closely related parasitoid wasps Nasonia vitripennis and N. longicornis. Both species occur microsympatrically in parts of their ranges and have been found in the same host pupae. Despite stron...

Collective cognition emerges from individuals responding to local information to make decisions. However, animals vary in how they learn to pay attention to important information, which has unknown consequences on collective behavior. We tested whether honey bee colonies comprised of individuals that differ in their capacity to focus their attention would choose to continue to visit learned, familiar food locations or switch to novel food locations. We found that colonies of focused bees preferr...

Collective cognition allows animal groups to accomplish many tasks that could not be accomplished as effectively alone, such as schools of fish avoiding predators, flocks of birds moving thousands of miles across the Earth, and honey bee colonies collecting food from millions of flowers. Individuals in groups utilize local information to quickly adjust to ecological changes by implicitly or explicitly communicating information with group members to form a collective decision. However, individual...

Long-chain cuticular hydrocarbons (CHC) are key components of chemical communication in many insects. The parasitoid jewel wasps from the genus Nasonia use their CHC profile as sex pheromone and for species recognition. The standard analytical tool to analyze CHC is gas chromatography coupled with mass spectrometric detection (GC/MS). This method reliably identifies short- to long-chain alkanes and alkenes, but CHC with more than 40 carbon atoms are usually not detected. Here, we applied two las...

The process of speciation is, according to the biological species concept, the reduction in gene flow between genetically diverging populations. Most of the previous theoretical studies analyzed the effect of nuclear genetic incompatibilities on gene flow. There is, however, an increasing number of empirical examples suggesting that cytoplasmically inherited genetic elements play an important role in speciation. Here, we present a theoretical analysis of mitochondrial driven speciation, in which...

Are we in the midst of a paradigm change in biology and have animals and plants lost their individuality, i.e., are even so-called ‘typical’ organisms no longer organisms in their own right? Is the study of the holobiont—host plus its symbiotic microorganisms—no longer optional, but rather an obligatory path that must be taken for a comprehensive understanding of the ecology and evolution of the individual components that make up a holobiont? Or are associated microbes merely a component of thei...

The molecular mechanisms that allow generalist parasitoids to exploit many, often very distinct hosts are practically unknown. The wasp Aphidius ervi, a generalist koinobiont parasitoid of aphids, was introduced from Europe into Chile in the late 1970s to control agriculturally important aphid species. A recent study showed significant differences in host preference and host acceptance (infectivity) depending on the host A. ervi were reared on. In contrast, no genetic differentiation between A. ...

Variation in behaviour among group members often impacts collective outcomes. Individuals may vary both in the task that they perform and in the persistence with which they perform each task. Although both the distribution of individuals among tasks and differences among individuals in behavioural persistence can each impact collective behaviour, we do not know if and how they jointly affect collective outcomes. Here, we use a detailed computational model to examine the joint impact of colony-le...
