Microbial symbionts of insects provide a range of ecological traits to their hosts that are beneficial in the context of biotic interactions. However, little is known about insect symbiont-mediated adaptation to the abiotic environment, e.g. temperature and humidity. Here we report on an ancient clade of intracellular, bacteriome-located Bacteroidetes symbionts that are associated with grain and wood pest beetles of the phylogenetically distant families Silvanidae and Bostrichidae. In the saw-toothed grain beetle Oryzaephilus surinamensis, we...
Data from: De novo transcriptome analysis of the excretory tubules of Carausius morosus (Phasmatodea) and possible functions of the midgut 'appendices'Matan Shelomi
The Malpighian tubules are the insect excretory organs, responsible for ion and water homeostasis and elimination of nitrogenous wastes. Post-genomic assays suggest they also metabolize and detoxify xenobiotic compounds and have antimicrobial properties. The Phasmatodea have an additional, unique set of excretory organs referred to predominantly as midgut appendices. Their function and how it compares to phasmid and other insect Malpighian tubules is unknown. Hypotheses include carbonic anhydrase activity, calcium and metal cation sequestration, and...
Data from: Herbivore-induced volatile blends with both “fast” and “slow” components provide robust indirect defense in natureYoungsung Joo, Meredith C. Schuman, Jay K. Goldberg, Sang-Gyu Kim, Felipe Yon, Christoph Bruetting & Ian T. Baldwin
1.Plants emit volatile blends specific to particular herbivore interactions, which predators and parasitoids learn to associate with prey, increasing herbivore mortality and thereby plant fitness in a phenomenon termed indirect defense. 2.Herbivore-induced plant volatile blends commonly include both rapid, transient green leaf volatiles (GLVs) and delayed, enduring sesquiterpenes. A few laboratory studies indicate that insects can use plant volatiles to time behavior, but it is not known whether and how the temporal dynamics of plant...
Data from: Burying beetles regulate the microbiome of carcasses and use it to transmit a core microbiota to their offspringShantanu P. Shukla, Heiko Vogel, David G. Heckel, Andreas Vilcinskas & Martin Kaltenpoth
Necrophagous beetles utilize carrion, a highly nutritious resource that is susceptible to intense microbial competition, by treating it with antimicrobial anal and oral secretions. However, how this regulates the carcass microbiota remains unclear. Here, we show that carcasses prepared by the burying beetle Nicrophorus vespilloides undergo significant changes in their microbial communities subsequent to their burial and ‘preparation’. Prepared carcasses hosted a microbial community that was more similar to that of beetles’ anal and oral...
Data from: Species divergence in offspring begging and parental provisioning is linked to nutritional dependencyAlexandra Capodeanu-Nägler, Anne-Katrin Eggert, Heiko Vogel, Scott K. Sakaluk & Sandra Steiger
In animal species in which parents provide food to their dependent young, offspring often display conspicuous begging signals. These solicitation behaviors are important components of parent–offspring communication, but it is currently unclear how they and the parental response covary with offspring dependency on parental food provisioning across species. Burying beetles (Nicrophorus) are well known for providing elaborate biparental care, including provisioning of begging larvae. By using a multispecies approach, we show that larval begging intensity,...
Data from: Manipulating two olfactory cues causes a biological control beetle to shift to non-target plant speciesNa Li, Jia-Ning Wei, Meredith C. Schuman, Shuang Li, Rui-Yan Ma & Jin Ge
Olfactory cues can determine the host preferences of herbivorous insects, but their role in host shifting is unclear. Host specificity and the potential for host shifts are important criteria for screening and post-release evaluation of biological control agents for invasive plants. However, the role of olfactory cues in mediating host shifts in biological control agents is not well understood. To investigate the role of olfactory cues in host selection of a reportedly monophagous flea beetle...
Data from: A Drosophila female pheromone elicits species-specific long-range attraction via an olfactory channel with dual specificity for sex and foodSebastien Lebreton, Felipe Borrero-Echeverry, Francisco Gonzalez, Marit Solum, Erika A. Wallin, Erik Hedenström, Bill S. Hansson, Anna-Lena Gustavsson, Marie Bengtsson, Göran Birgersson, , Hany K. M. Dweck, Paul G. Becher & Peter Witzgall
Background: Mate finding and recognition in animals evolves during niche adaptation and involves social signals and habitat cues. Drosophila melanogaster and related species are known to be attracted to fermenting fruit for feeding and egg-laying, which poses the question of whether species-specific fly odours contribute to long-range premating communication. Results: We have discovered an olfactory channel in D. melanogaster with a dual affinity to sex and food odorants. Female flies release a pheromone, (Z)-4-undecenal (Z4-11Al),...
Data from: A context-dependent induction of natal habitat preference in a generalist herbivorous insectPatrick Lhomme, David Carrasco, Mattias Larsson, Bill Hansson & Peter Anderson
In many species adults exploit sensory information experienced in their natal habitat when searching for resources. This behavioral plasticity may help animals to establish themselves in new habitats by quickly locating suitable resources and avoiding unsuitable resources in complex environments. However the processes guiding positive or negative natal habitat preference induction (NHPI) remain poorly understood. In the polyphagous moth Spodoptera littoralis, earlier studies have shown that female innate host-plant preference is modulated by larval feeding...
