In the course of investigating the eriophyoid mites’ fauna (Acari: Eriophyoidea) in Northwest Iran, one new eriophyid species, Aceria lactulignae sp. nov. was discovered and described. The new species was collected on Lactuca saligna L. (Asteraceae) as vagrant mite and no apparent symptom was observed. This is the third eriophyoid mite to be associated with this host plant genus around the world. Key Words: Aceriini, East Azerbaijan, Eriophyinae, Jolfa, Lactuca

Micronola wadicola Amsel, 1935 is recorded for the first time from Europe based on a single male collected in the island of Pantelleria (Strait of Sicily, Italy), near Bagno dell’Acqua lake. The species was previously known from Jordan, SW Iran, SW Saudi Arabia, Oman, and Yemen. Identification hints, information and illustrations are provided. The finding of this species shows that the inventorying of the lepidoptera fauna of Pantelleria, from where 151 species have so far been recorded, is still far away from completion and needs further efforts.

Toumeyella parvicornis, native to the Nearctic regions, represents an increasing threat to pine forests worldwide. Severe infestations of this invasive scale have long been present in the Caribbean Islands of Turks and Caicos (TCI), and recently in Europe (Italy and France). Classical biological control could represent the most promising method for the long-term management of To. parvicornis in newly invaded areas. This study, based on an entomological expedition to Turks and Caicos Islands, allowed the discovery and selection of the coccinellid predator Thalassa montezumae as a potential biological control agent. This predator was never recorded before on TCI and was probably introduced from the area of origin of To. parvicornis. Here, the rate of infestation was evaluated and the pest suppression impact of Th. montezumae was investigated, both in the field and under laboratory conditions. Given the promising results of field studies and predation tests, the predator was imported into Italy, under quarantine conditions, to carry out a preliminary risk assessment to evaluate its potential impact on non-target species. Predation tests were conducted on different developmental stages of various scales and other Hemiptera (e.g., Aphididae, Aleyrodidae) common in Europe. The results reveal that Th. montezumae predates only scales, mainly at juvenile stages, but with a rate of predation significantly higher for To. parvicornis. Further studies are needed to mitigate the risk of underestimating environmental impacts in the use of Th. montezumae as a biological control agent for To. parvicornis.

Diptera is a crucial component of temperate forest systems in Europe. Vertical distribution of Diptera in forests is still insufficiently studied and there are many unanswered questions. The study has been conducted in the Republic of Mordovia (central European Russia). To collect insects, traps with beer and sugar bait were used. Collections were made during the period of June–September 2020 in four sites in deciduous forests. The maximum number of Diptera specimens has been collected at the height of 1.5 m from the ground level, and the minimum at the height of 3.5 m. Species from eight families (Anisopodidae, Calliphoridae, Drosophilidae, Fanniidae, Lonchaeidae, Milichiidae, Muscidae, Tipulidae) represent the main part of the sampled specimens. Calliphoridae, Drosophilidae, Dryomyzidae and Tipulidae, were most abundant at the height of 1.5 m from ground level. At the height of 12 m in the canopy, Anthomyiidae, Chloropidae, Lonchaeidae, Milichiidae, Periscelididae and Syrphidae were most abundant. Numbers of Fanniidae and Muscidae were almost equal at all heights. The species diversity of Muscidae was represented in the traps by 10 well-recofnized species. The most abundant species was Phaonia pallida (70.7%). Two species Thricops simplex (12.2%) and Muscina pascuorum (5.8%) were less abundant. Thricops simplex showed the greatest confinement to the height of 1.5 m, while Phaonia pallida increased in abundance from lower to higher levels of the forest community. The vertical distribution of Muscina pascuorum did not depend on the height of the trap. Key Words: beer trap, Mordovia State Nature Reserve, insects, dynamics, number

A new free-living nematode Tetratobrilus dentatus gen. nov. sp. nov. under family Tobrilidae Filipjev, 1918 of the order Triplonchida Cobb, 1919 is described from a drowned paddy field soil (mud) in West Bengal, India. It is characterized by heavily sclerotized walls of anterior portion of the buccal cavity, a small dorsal tooth and two sub-ventral stomatal pockets longitudinally, one following another. The first pocket is fused with the posterior portion of the stoma, similar to the genus Epitobrilus, but differs in the presence of two adjacent teeth (vs. one) in the first pocket. The second pocket contains only one tooth. It also possesses smaller anterior setae (less than 40% of head diameter) and a subterminal setae. Males bear six characteristic pitcher-shaped supplements. Comprehensive details regarding the morphological structures, accompanied by figures and morphometric measurements, are presented in this report. An updated key to the genus and other genera of family Tobrilidae is also provided. Key Words: Stomatal pockets, sub-ventral teeth, Tobrilidae, new genus, new species

Terrestrial isopods are generally considered as detritivore invertebrates, but in recent years and in different parts of the world they seem to become potential agricultural pests for different crops. The crops affected so far have been mainly arable crops, but damages to few horticultural crops were also documented. Until now, no referenced problems with isopods as crop pests had ever occurred in Italy. In March/April 2023 on two organic farms in northern Italy newly transplanted seedlings of smooth melon in greenhouses were damaged by isopods. Among farms, the loss was estimated between 40% and 50% of the seedlings. The isopod that caused the damage was identified as Armadillidium arcangelii, and, until now, the species had never been reported as a crop pest.

The FLOTAC basic technique is a recognised method used mainly in the veterinary field to extract parasites from the faeces of animals found in the stomach and intestine. This study is the first application of the FLOTAC and Mini-FLOTAC techniques to extract infective juveniles of entomopathogenic nematodes from infested Galleria mellonella. The EPN used for this purpose was an endemic Italian nematode belonging to the Rhabitidae family Steinernema carpocapsae. Galleria mellonella larvae were infected and extraction was performed a few days after infection using both techniques. A comparison was then made between the two methods. The results showed that infective juveniles could be extracted from the infected larva as early as three days after infection. The difference between the FLOTAC basic technique and the Mini-FLOTAC technique was not significant in the extraction of entomopathogenic nematodes. Due to its sensitivity and operating easiness the Mini-FLOTAC technique is a promising method for the extraction of entomopathogenic nematodes. It allows faster extraction of nematodes from the inhabited soil and insect host than the conventional White trap method.

The crops affected so far have been mainly arable crops, but damages to few horticultural crops were also documented. Until now, no referenced problems with isopods as crop pests had ever occurred in Italy. In March/April 2023 on two organic farms in northern Italy newly transplanted seedlings of smooth melon in greenhouses were damaged by isopods. Among farms, the loss was estimated between 40% and 50% of the seedlings. The isopod that caused the damage was identified as Armadillidium arcangelii, and, until now, the species had never been reported as a crop pest.
