Abstract:
The invasive hornet Vespa velutina Lepeletier, which first invaded South Korea in 2003, has spread throughout the country, significantly affecting apiaries, ecosystems, and human health. Xenos spp. (Xenidae, Strepsiptera) are primarily parasitic to social wasps, with V. analis being the only known host in Korea. Until recently, no parasites or parasitoids on V. velutina had been discovered. In 2020, strepsipteran parasites were discovered on 11 hornet workers in Andong City, South Korea. These parasites, comprising four larvae and seven pupae, were all male, except for one individual of an und

Abstract:
Parasite growth in hosts depends on their hosts’ nutritional status. This study examined whether the body size of the strepsipteran parasite Xenos oxyodontes, which parasitizes the eusocial wasp Vespa analis, is affected by several key factors, including host body size. We collected V. analis using bait traps for three years in Niigata, Japan, and evaluated the number of male and female X. oxyodontes parasites throughout the seasons. A total of 185 female parasites were collected, and their cephalothorax widths were measured. The widths of female parasites did not statistically vary among seas

Abstract:
SUMMARYHost castration represents a mechanism used by parasites to exploit energy resources from their hosts by interfering with their reproductive development or to extend host lifespan by removing risks associated with reproductive activity. One of the most intriguing groups of parasitic castrators is represented by the insects belonging to the order Strepsiptera. The macroparasite Xenos vesparum can produce dramatic phenotypic alterations in its host, the paper wasp Polistes dominula. Parasitized female wasps have undeveloped ovaries and desert the colony without performing any social task.

Abstract:
Xenos is a strepsipteran genus parasitizing hornets of the Vespa spp. In Japan, parasitism levels in hornets have been examined for two Xenos species. These studies have indicated that parasitism levels vary with the seasons but are inconsequential compared to other potential factors that reduce the number of host colonies. However, a comprehensive analysis of parasitism levels accounting for various factors such as host species, seasons, and years was not conducted. To address this gap, we conducted a four-year study in which we collected Vespa spp. using bait traps and assessed parasitism le

Abstract:
SUMMARYSocial wasps can face many challenges during their colony cycle, including the presence of parasites. The order Strepsiptera is among the main parasites of the wasp genus Polistes. The aim of this study was to evaluate the effect of an endoparasite species on the host Polistes ferreri, with the hypothesis that females of this social wasp would undergo morphophysiological alterations as well as changes in their cuticular chemical profile caused by the obligate endoparasite. On average, parasitism was found in 10% of the colonies studied. All the parasitized females showed filamentous ova

Abstract:
Traumatic insemination describes an unusual form of mating during which a male penetrates the body wall of its female partner to inject sperm. Females unable to prevent traumatic insemination have been predicted to develop either traits of tolerance or of resistance, both reducing the fitness costs associated with the male-inflicted injury. The evolution of tolerance traits has previously been suggested for the bed bug. Here we present data suggesting that tolerance traits also evolved in females of the twisted-wing parasite species Stylops ovinae and Xenos vesparum. Using micro-indentation ex

The recent rediscovery of this Stylops from an individual of A. savignyi permits a reinterpretation of the species and its affinities among other Stylops.

We field-collected 24 wasp nests in early July 2012, isolated parasitised wasps, tracked life history events of X. peckii, and recorded such behaviour as emergence of males and mating by normal-speed and high-speed cinematography. To emerge, males first cut the puparium with their mandibles along an ecdysial suture line, and then push aside the pupal cap during emergence. The endoparasitic females

Abstract:
Paper wasps (Polistes dominula), parasitized by the strepsipteran Xenos vesparum, are castrated and desert the colony to gather on plants where the parasite mates and releases primary larvae, thus completing its lifecycle. One of these plants is the trumpet creeper Campsis radicans: in a previous study the majority of all wasps collected from this plant were parasitized and focused their foraging activity on C. radicans buds. The unexpected prevalence and unusual feeding strategy prompted us to investigate the influence of this plant on wasp behavior and physiology through a multidisciplinary

Species of the Family Agaonidae are associated with the genus Ficus , as the species of the subfamily Agaoninae behave as pollinators, while the other species are mainly parasites of pollinators or gall formers from other parts of the fig. The male's life cycle is exhausted inside the fig tree's syconium: its role is to mate with the female and, therefore, with its robust jaws, open an exit for her (it is the opposite of what happens among the Strepsiptera, in which the female never leaves the host). Once fertilized, the female will leave the host fig to lay eggs in other figs, thus completing

Abstract:
Polistes dominulus are social wasps which are the host of the strepsipteran endoparasite Xenos vesparum. In the hibernating phase, unparasitized and parasitized wasps leave natal nests and aggregate together in sheltered quarters. In aggregations, wasps are socially active, and some individuals perform helping behaviour. Here we investigated if castrated parasitized wasps perform worker tasks in mixed aggregations. Moreover, by gas chromatography and mass spectrometry, we examined the cuticular hydrocarbons of unparasitized and parasitized wasps to evaluate if the infection alters the composit

The cephalic anatomy is described in detail, based on a 3D-reconstruction. It was possible to show the proportions of the exo- and endocuticle and the epidermis.

AbstractA female stylopid parasitising an ant of the genus Prionomyrmex (Hymenoptera: Formicidae) is described and illustrated from Baltic amber (Eocene, 39-50 million years old). This new fossil is tentatively considered as a plesiomorphic member of the Myrmecolacidae. Recent Myrmecolacidae parasitise dual hosts: males parasitise Formicidae, while females parasitise either Mantodea or Ensifera. This is the first record of a female stylopid parasitising Formicidae. The phylogenetic relationships of the Myrmecolacidae and the origin of their unique dual host relationship are discussed.
