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

Despite the ecological importance of parasitoid wasps for the stability of Alps ecosystems, the available knowledge about braconid wasps for these environments is still very limited. Here, we explored the diversity of Alpine braconid parasitoids in the Southern Central Alps. We recorded 18 species of braconids, 12 of which are from the subfamily Aphidiinae. In particular, we detected for the first time the alien parasitoid species Lysiphlebus testaceipes (Cresson) in the Alps, providing information that could be considered to evaluate the invasiveness of this species. The second most diverse subfamily was Microgastrinae with two detected species, while one species was recorded from each of the subfamilies Alysiinae, Braconinae, Cheloninae and Euphorinae. Four braconid species from the subfamily Aphidiinae – Aphidius hieraciorum Starý, Aphidius schimitscheki (Starý), Harkeria angustivalvus (Starý) and Monoctonus crepidis (Haliday) – are new records to the fauna of Italy. This work contributes to the knowledge of braconid diversity in the Alps. Moreover, it can be a starting point both to explore complex tritrophic interactions potentially threatened by climate change and the role of early flowering Alpine plants on braconid diversity. Key Words: Alps, Alpine ecosystems, biotic interactions, braconids, Italian fauna, parasitoids.

Alien lacebugs have been recorded in most Mediterranean countries and, in Italy, in several western coastal regions. In this work, we collected new data on the jasmine lacebug Corythauma ayyari through a citizen-science approach. We reported for the first time its presence in three new Italian regions (Lombardy, Piedmont, and Marche), as well as in the hinterland areas of Israel, France, and Spain, up to over 220 km from the nearest coastal area. Through molecular analyses based on the mitochondrial gene of cytochrome oxidase I, we identified three new mitochondrial haplotypes in Italy, suggesting the possibility of recent introductions through plant trading. The increased distribution range towards the European hinterlands by C. ayyari needs to be monitored, as these introduced aliens are responsible for severe impacts on ornamental plants. Furthermore, improved controls in port areas should be recommended to prevent new invasions. We strongly recommend using multi-taxon, pan-continental platforms of citizen-science to collect data and keep the distribution of alien species updated.

外来草蜻蛉在大多数地中海国家都有记录，在意大利，几个西部沿海地区也有记录。在这项工作中，我们通过公民科学方法收集了有关茉莉草蛉 Corythauma ayyari 的新数据。我们首次报告了它在意大利三个新地区（伦巴第、皮埃蒙特和马尔凯）以及以色列、法国和西班牙腹地的存在情况，这些地区距离最近的沿海地区超过 220 公里。通过基于细胞色素氧化酶 I 线粒体基因的分子分析，我们在意大利发现了三种新的线粒体单倍型，这表明可能是最近通过植物贸易引入的。需要对 C. ayyari 在欧洲腹地的分布范围扩大进行监测，因为这些引入的外来物种对观赏植物造成了严重影响。此外，应建议加强对港口地区的控制，以防止新的入侵。我们强烈建议利用多物种、泛大陆的公民科学平台来收集数据，并不断更新外来物种的分布情况。关键字Corythauma ayyari；地中海盆地；线粒体 DNA；在线公民科学平台；廷科。

Lethocerus patruelis (Stål, 1854) is the only member of the Belostomatidae family in Europe. During the last decades, records of this giant water bug have become frequent in south-eastern Italy, but with no evidence about its origin (man-mediated unintentional introduction or a natural westward spread). The status of this species in Italy is still uncertain, but the man-mediated unintentional introduction seems the most probable, even through multiple introductions. The first record of Lethocerus cf. patruelis for the Campania region (the first one on the Tyrrhenian side of Italy) is here reported, suggesting the already registered tendency of this species to expand, at least in Europe. Several topics need to be evaluated, in the light of its status in Italy and its management. Key Words: aquatic insect; distribution; Heteroptera; Nepomorpha; new record.

The gall-inducing Asian Chestnut Gall Wasp (ACGW), Dryocosmus kuriphilus is one of the most harmful pests of Castanea species in the world. In 2005, Torymus sinensis, a species-specific parasitoid of the ACGW, native to China, was released in Italy as a biological control agent. After more than ten years from the first T. sinensis release, ACGW only sporadically affects chestnut production. However, some areas of Tuscany such as Villore (Tuscany, Italy) still remain active ACGW hotspots and even though its distribution is much more jeopardized than in the past, several recurrent outbreaks have been recently reported. In the present work, we evaluated the possibility of storing leaf galls in the field, during the cold season, in order to protect T. sinensis immatures overwintering within them. In particular, the hypothesis was tested that above-ground storage of leaf galls could increase parasitoid survival in a Castanea sativa orchard near Villore (Tuscany, Italy). Results showed that T. sinensis survival in leaf galls stored above ground was higher than that recorded on galls stored on the ground, proving that this method was effective in protecting overwintering immatures from adverse environmental conditions. Our study provided chestnut growers with a new tool aimed at enhancing T. sinensis activity in C. sativa orchards. Key Words: Castanea sativa, natural enemies, parasitoids survival, galls storings methods
亚洲栗瘿蜂（ACGW），Dryocosmus kuriphilus 是世界上最有害的蓖麻害虫之一。2005 年，原产于中国的亚洲栗瘿蜂物种特异性寄生虫 Torymus sinensis 作为生物控制剂被释放到意大利。在首次释放 T. sinensis 十多年后，ACGW 只对栗树生产造成零星影响。然而，托斯卡纳的一些地区，如维罗尔（意大利托斯卡纳），仍然是 ACGW 的活跃热点地区，尽管其分布比过去受到更严重的危害，但最近仍有几起反复爆发的报道。在本研究中，我们评估了在寒冷季节将叶瘿储存在田间的可能性，以保护在叶瘿中越冬的中华绒螯龙葵幼虫。特别是，我们在维洛雷（意大利托斯卡纳）附近的一个蓖麻果园中测试了叶胆地上储藏是否能提高寄生虫存活率的假设。结果表明，地上储藏的叶瘿中中华蓟马的存活率高于地面储藏的叶瘿，证明这种方法能有效保护越冬幼虫免受不利环境条件的影响。我们的研究为板栗种植者提供了一种新工具，旨在提高板栗果园中 T. sinensis 的活性。关键字板栗、天敌、寄生虫生存、虫瘿贮存方法
