Symbiotic Bacteria Protect Wasp Larvae from Fungal Infestation
TLDR
This is the first report on the cultivation of bacteria in insect antennae and the first case of a symbiosis involving bacteria of the important antibiotic-producing genus Streptomyces, which might play an important role in other insects as well. Expand
Larvae of the parasitoid wasp Ampulex compressa sanitize their host, the American cockroach, with a blend of antimicrobials
TLDR
The data suggest that the specific combination of antimicrobials in the larval secretion provides an effective frontline defense against the unpredictable spectrum of microbes that A. compressa larvae may encounter during their development inside their cockroach hosts. Expand
Brothers smell similar: variation in the sex pheromone of male European Beewolves Philanthus triangulum F. (Hymenoptera: Crabronidae) and its implications for inbreeding avoidance
TLDR
One crucial prerequisite for females to be able to discriminate against brothers and avoid inbreeding is that the male sex pheromone varies with familial affiliation, and this hypothesis was tested by analysing the phersomone of male progeny of eight mothers using gas chromatography and mass spectrometry. Expand
Partner choice and fidelity stabilize coevolution in a Cretaceous-age defensive symbiosis
TLDR
It is demonstrated that host control over symbiont transmission (partner choice) reinforces partner fidelity between solitary wasps and antibiotic-producing bacteria and thereby stabilizes this Cretaceous-age defensive mutualism. Expand
Prey recognition by females of the European beewolf and its potential for a sensory trap
TLDR
Female European beewolves have a high sensitivity for ( Z )-11-eicosen-1-ol that probably evolved in the context of prey hunting, therefore, males that included this compound in their sex pheromone probably attracted more females and experienced a selective advantage according to the sensory trap model. Expand
'Candidatus Streptomyces philanthi', an endosymbiotic streptomycete in the antennae of Philanthus digger wasps.
TLDR
On the basis of morphological, genetic and ecological data, 'Candidatus Streptomyces philanthi' is proposed and 16S rRNA gene sequence data are provided for 28 ecotypes that reside in different host species and subspecies of the genus Philanthus. Expand
Refining the Roots of the Beewolf-Streptomyces Symbiosis: Antennal Symbionts in the Rare Genus Philanthinus (Hymenoptera, Crabronidae)
TLDR
The presence of “Ca. StrePTomyces philanthi” in antennal glands of Philanthinus indicates that the symbiosis between beewolves and Streptomyces bacteria is much older than previously thought. Expand
Is the postpharyngeal gland of a solitary digger wasp homologous to ants? Evidence from chemistry and physiology
TLDR
The hypothesis of a homologous origin of the PPG in beewolves and ants is supported by the results support the considerable morphological similarities into account. Expand
Fighting fungi with physics: Food wrapping by a solitary wasp prevents water condensation
TLDR
This work reports on a mechanism employed by a solitary wasp to preserve its larval provisions against molding, which is used by female European beewolves to hunt honeybees and store one to six paralyzed bees in subterranean brood cells as food for each of their larvae. Expand
Volatiles of foraging honeybees Apis mellifera (Hymenoptera: Apidae) and their potential role as semiochemicals
TLDR
Which compounds occurs on the cuticle of honeybee workers are analysed and which might be used as kairomones by females of the European beewolf Philanthus triangulum to identify their prey are analyzed. Expand
