“…The study of single-nucleotide polymorphisms (SNPs), a type of DNA marker, has progressed to a higher level of understanding its connection to gene function [30,31]. Vespa wasps have been the subject of several scientific investigations into their ecological [32,33], biological [34,35], behavioural [36], genetic [36], microbiological [37], host plant [38], and molecular phylogenetic [20,38] aspects. However, information on SNPs in oriental wasps is currently unavailable.…”

Oriental wasps are scavengers, and they have also represented an enormous issue for beekeepers, they destroy beehives and reduce the flight of bees. In addition, the sting of hornets may cause medical problems, which differ according to the response of the individuals, including severe sensitivity, swelling, and slight pain. This study provides the first molecular phylogeny of the oriental wasp Vespa orientalis L. in Iraq. Mitochondrial DNAs of the 547bp fragment cytochrome oxidase subunit 1 (CO1) area were sequenced and analyzed from 10 wasp specimens collected in the north, middle, and south of Iraq. The CO1 gene found in the Iraqi isolates was used to create a Bayesian interference. Maximum likelihood (ML) was used to create the phylogenetic tree. Results, according to the results of the phylogenetic analysis, the CO1 gene may be used to positively identify every sample, and there is a close connection between the sequences of samples from various regions of Iraq, with 100% of the samples clustering together. PCR successfully amplified 547bp products for all examined oriental wasp samples. Considering the similarity in the sequences, the Iraqi local species are classified as V. orientalis. Conclusion, in this study, V. orientalis isolates which were collected from different geographical regions in Iraq were closed and there was low variation. The DNA barcode component of CO1 was found to be an effective method for the quick and precise identification of Iraqi oriental wasps.

“…The adult workers are responsible for feeding the larvae [24,25]. These hunt different species of insects in flight, such as different species of bees, other wasps, dipterons, and even arachnids [23].…”

“…The larvae also collaborate in feeding the colony by means of a reciprocal exchange of food (trophalaxy). In the particular case of the larvae, they reward the workers using a highly energetic oral secretion, rich in sugars, proteins, and free amino acids, which creates a dependency on the worker and ensures that the larvae are fed regularly [13,24]. This could justify the presence of pollen in the gastrointestinal content of the larvae.…”

Vespa velutina is an invasive species that exhibits flexible social behavior, which may have contributed to its introduction in several European countries. It is important to understand its behavior in order to combat the effects of its introduction in different areas. This implies knowing the resources that it uses during its biological cycle. Hornets require protein resources taken from insects and organic matter as well as carbohydrates as an energy source to fly and also to forage for food and nest-building materials. The gastrointestinal tract of adults and larvae contains a wide variety of pollen types. The identification of this pollen in larvae collected from nests could offer information about the plant species that V. velutina visits as a foraging place. The main objective of this research was to study the pollen content in the gastrointestinal tract of larvae. Patterns of pollen content and pollen diversity were established according to the nest type, altitude, season, and location in the nest comb. The abundance of pollen types such as Eucalyptus, Castanea, Foeniculum vulgare, Hedera helix, Taraxacum officinale, Echium, or Cytisus pollen type stands out in many of the samples.

“…In our research group, an observational study on the behaviour of Vespa velutina in captivity has been carried out [11]. Two secondary nests and one embryonic nest were captured and kept under controlled environmental conditions for up to 13 weeks for the secondary nest and 6 weeks for the embryonic nest.…”

Vespa velutina nigrithorax has become an invasive species since its introduction in Europe, as it is a predator of native fruits and insects, mostly honeybees. In this chapter, the morphology of the Vespa velutina is described together with its life cycle and the morphology of the nest that this hornet builds. The proliferation of this invasive species in Europe and the economic, environmental and human health impact that it produces makes necessary the use of methods for its control. The methods for the inactivation of nest, trapping hornets and minimising the impact on apiaries are the established methods to fight against this species. Behavioural study of these hornets in captivity has been carried out to increase the knowledge on the ethology of Vespa velutina. For this purpose, two secondary nests and one embryonic nest were captured and kept under controlled environmental conditions for up to 13 weeks for the secondary nest and 6 weeks for the embryonic nest. Adaptation to captivity, defence against disturbance, colony evolution and hibernation were the different behaviours observed. The results of this research will allow us to obtain additional information on this species, which are crucial to develop effective control methods for this invasive species.
