Hymenoptera Ichneumonidae of Montecristo Island (Tuscan Archipelago), with some new records for the Italian fauna
Full text linkData on the presence in the Island of Montecristo (Tuscan Archipelago, Italy) of 35 taxa of Ichneumonidae (Hymenoptera Ichneumonoidea) are provided. The specimens were collected with a Malaise trap in 2011 and 2012. Seven of the identified species were already known for the Tuscan archipelago, four for the Island of Montecristo. The total number of Ichneumonidae in the Archipelago rises from 20 to 49 species, that of Montecristo from 5 to 36. Eleven species are new records for South Italy. Townostilpnus chagrinator Aubert, 1916, previously known only from Corsica and southern France, is new to Italy
Composizione delle comunità di Imenotteri Icneumonidi (Hymenoptera, Ichneumonidae) in habitat frammentati
Full text linkGli Icneumonidi rappresentano il gruppo con la maggiore diversità in specie tra gli Imenotteri e uno
dei gruppi ad avere avuto una notevole radiazione adattativa, con adattamenti in gran parte dei biomi
terrestri. In questo studio sono state prese in esame le comunità di icneumonidi delle foreste planiziali relitte e degli impianti naturaliformi della Pianura Padana orientale. Una prima analisi ha riguardato lo studio della distribuzione orizzontale e verticale degli icneumonidi nella Riserva Naturale di Bosco della Fontana (Lombardia). Secondariamente, sono state analizzate le comunità di icneumonidi dei querco-carpineti relitti e degli impianti naturaliformi di recente costituzione, presenti nella Pianura Padana veneta e friulana. In parallelo, è stata sviluppata una chiave interattiva per la discriminazione delle sottofamiglie e tribù di icneumonidi della fauna europea, che possa rappresentare uno strumento utile a favorire un primo approccio al gruppo ed incentivarne l'uso in ecologia
The European grape berry moth, Eupoecilia ambiguella (Lepidoptera: Tortricidae): Current knowledge and management challenges
No full textThe European grape berry moth, Eupoecilia ambiguella (H & uuml;bner) (Lepidoptera: Tortricidae), since its first identification in 1796, was defined as a key pest for European viticulture despite its polyphagy. Although between the late 1800s and early 1900s its presence and spread in Europe was of concern, to date its populations are low and limited to cooler and wetter areas, leading to a decline in its importance. In the present work, we reviewed its global distribution as well as its morphology, biology, and ecology. Considering the monitoring and management of this pest, the present review summarised insecticidal, agronomic, and cultural control strategies. Moreover, given the need to reduce the impact of agriculture on the environment, humans, and non-target species, we focused on control strategies relying on pheromones and biological control agents (e.g. predators and parasitoids) involved in conservation biological control
C’è una larva nel mio piatto! Diffusione degli insetti nella dieta occidentale.
Full text linkInsects are commonly eaten by more than two billion people around the world. EFSA's recent
approval of Tenebrio molitor larvae as food paves the way for insect consumption in the European
Union. The introduction of insects as food in the diet of Western countries could be an environmentalfriendly solution to the growing demand for animal proteins over intensive farming. Despite advances
in legislation and food safety, there is still a cultural barrier to be overcome, which still considers
insects as organisms harmful to agriculture and human
First record of the antlion Solter liber Navás, 1912 in Italy (Neuroptera, Myrmeleontidae)
Full text linkMyrmeleontidae are conspicuous insects with moderate species diversity, which are reasonably well studied in Europe. However, dedicated samplings in the Mediterranean region carried out in the last years suggest that the state of knowledge of the representatives of this family occurring in outhern Europe is far from ideal. Over 40 species of antlions and owlflies are reported from Italy, of which a few are only known from the islands of the Sicilian Channel.Solter liber Navás, 1912 is reported for the first time in Italy, based on specimens collected in Pantelleria Island in 2022 and 2023
Description of the first species of Nemeritis Holmgren (Hymenoptera Ichneumonidae: Campopleginae) from the Southern Hemisphere, with a key to the New World species

New species and records of Afrotropical Campopleginae (Hymenoptera: Ichneumonidae)
Full text linkTwo new Afrotropical ichneumon wasp species are described: Casinaria latericia Vas, sp. n. from Uganda, and Venturia mortifera Vas, sp. n. from Burundi. First records of Charops ater Szépligeti, 1908 from Burundi, Charops electrinus Vas, 2020 from Central African Republic, and Charops juliannae Vas, 2020 from Uganda are reported. With 2 figures
Vertical stratification of selected Hymenoptera in a remnant forest of the Po Plain (Italy, Lombardy) (Hymenoptera: Ampulicidae, Crabronidae, Sphecidae)
Full text linkCommunities of the canopy of temperate forests are still relatively unexplored. Furthermore, very little is known on how vertical stratification for some insect groups is related to biological strategies. In this study, we investigated the community composition of both canopy and understory of the families Ampulicidae, Crabronidae and Sphecidae (Hymenoptera) of the Natural Reserve of "Bosco della Fontana", a remnant lowland forest in northeastern Italy. Observed patterns in vertical stratification have been related to species foraging habits. Our study reveals that the bulk of the community of Spheciformes of the understory consists of species predating dipterans and spiders, while species associated with the canopy are mainly predators of sap-sucking honeydew producers and epiphyte grazers, like aphids, thrips, and barkflies. Comparing the communities of canopy and understory may lead to a better understanding of species ecology and provides useful information to forest managers
Description of the male of Misetus strumiai Di Giovanni, Scaramozzino & Diller, 2018 (Hymenoptera, Ichneumonidae, Ichneumoninae, Phaeogenini) from Italy
No full textThe genus Misetus Wesmael, 1845 is a small taxon of the subfamily Ichneumoninae, tribe Phaeogenini. The genus can
be distinguished from other genera of the tribe by having mandible with two teeth, clypeus with more or less developed
median apical tooth, genae short and sublinearly narrowed behind eyes in dorsal view; males are characterized by thyridia large and placed far off the base of metasomal tergite II; females are easily recognized by metasoma elongate and
compressed apically, apical margin of last metasomal tergite more or less concave and ovipositor short and bent upwards
(Selfa & Diller 1994, 1995, Di Giovanni et al. 2018). Misetus includes seven known species, six of which occur in Europe (Wesmael 1845, Kusigemati 1974, Kolarov 1985, Selfa & Diller 1995, Di Giovanni et al. 2018) and one in Japan
and South Korea (Kwon et al. 2011; Yu et al. 2012). Misetus strumiai Di Giovanni, Scaramozzino & Diller, 2018 was
described recently from females known only from the island of Montecristo (Italy, Tuscany) (Di Giovanni et al. 2018, Di
Giovanni & Scaramozzino 2019). Here we described the male of this species and provide a comparative diagnosis with
other known males of European members of the genus
Revision of the Afrotropical genus Protoleptops Heinrich, 1967 (Hymenoptera, Ichneumonidae, Ichneumoninae), with description of a new species from Burundi
Full text linkThis study presents a comprehensive revision of the genus Protoleptops Heinrich, 1967. We describe a new species, P. nyeupe Dal Pos & Di Giovanni, sp. nov., from Burundi, marking the first documented occurrence of an Ichneumoninae species in the country. Additionally, we provide the first diagnostic description of the female P. farquharsoni Heinrich, 1967 and report a new occurrence of this species in KwaZulu-Natal. Furthermore, we document P. magnificus for Mpumalanga (South Africa) and P. angolae Heinrich, 1967 in Uganda, thereby extending the known range of the latter into East Africa. A detailed catalogue of all species within the genus Protoleptops is also included
