Synopeas maximum Awad & Talamas, sp. nov. , the first reported parasitoid associated with the soybean gall midge, Resseliella maxima Gagné, is described based on morphological and molecular data. Parasitoids were reared from soybean stems infested by R. maxima in Minnesota. A phylogenetic reconstruction of the genus Synopeas Förster was performed with COI sequences (n=2412) available on the Barcode of Life Data System (BOLD). Phylogenetic and barcode gap analyses suggest 279 Synopeas species in this dataset, with S. maximum sequences forming a monophyletic clade that is distinct from relatives. The Synopeas maximum clade was close to specimens from Canada and the United States, suggesting it is native to North America. We present a taxonomic treatment of S. maximum to facilitate its identification, including comparison to morphologically similar species. This project provides baseline data for further ecological study of R. maxima parasitism, and its management in soybean.
Synopeas的最大Awad &摘要根据形态和分子数据，首次报道了与大豆瘿蚊相关的寄生蜂——大鼠瘿蚊(Resseliella maxima gagn)。在明尼苏达州以大豆茎为寄生源，饲养拟寄生物。利用条形码生命数据系统(BOLD)中的COI序列(n=2412)对Synopeas属Förster进行系统发育重建。系统发育和条形码差异分析表明，该数据集中有279个Synopeas物种，其中S. maximum序列形成了一个与近亲不同的单系分支。Synopeas的最大分支与加拿大和美国的标本接近，表明它原产于北美。我们提出了一种分类处理，以方便其识别，包括比较与形态相似的物种。本项目为进一步开展大豆大叶蚜的生态学研究和管理提供了基础资料。

Fossil species of bethyline wasps from Dominican amber are revised. Based on a cladistic analysis of female morphological data we recognize a new genus and species, † Crassibethylus dominicanus gen. et sp. nov. , which came out as sister group of the clade Odontepyris + Prosierola . We also transfer to Bethylidae a fossil taxon originally described in Sclerogibbidae, placing † Pterosclerogibba Olmi as a new junior synonym under Goniozus Förster, in the new combination † Goniozus antiquus (Olmi). Additionally, the third species of Bethylinae known from Dominican amber, † Goniozus respectus Sorg, is diagnosed and illustrated with color images of the holotype. An identification key to the species of Bethylinae from Dominican amber is provided.

Stingless bees have a sophisticated system of chemical communication that helps conspecifics find food sources. In this study, we investigated whether Melipona beecheii foragers deposit a chemical mark on food to recruit conspecifics. Our results showed that foragers preferred to visit the feeders visited previously by conspecifics over clean feeders. We also found that foragers preferred visiting feeders baited with labial gland extracts over those baited with mandibular extracts or hexane. Labial gland extracts elicited higher forager antennal responses compared with those evoked by the mandibular gland extracts or hexane. Labial gland extracts and extracts from feeders visited by foragers contain a mixture of unsaturated hydrocarbons, followed by straight chain hydrocarbons and small quantities of esters. The main component is a mixture of alkene isomers C27:1.

Vigueira, Patrick A., Vigueira, Cynthia C., Campbell, Joshua W., Ladner, Samia, Hayes, Gabrielle, Riser, Elizabeth
A multitude of hymenopteran species exhibit sexual dimorphism for simple traits, such as color, size, or antennal segment number. These differences can reflect selection for specialized biological roles, many of which have not been documented for the majority of bee and wasp species. The excess power index (EPI) is an estimate of insect flight performance that is inferred by the combination of several morphological characteristics. We compared the female and male EPIs in four species of native bees: Agapostemon virescens Fabricius, Andrena carlini Cockerell, Melissodes bimaculata Lepeletier and Xylocopa virginica L.. While females of each species had a significantly larger whole body mass, males had a significantly larger EPI. A larger body mass for females is associated with egg laying abilities and foraging behavior. Male fitness may be dependent on EPI; males that have greater flight capacity can travel further or remain in flight for longer time periods in search of mates.

A new species of parasitoid wasp (Braconidae, Microgastrinae) from the kingdom of Saudi Arabia (KSA) is described, Microplitis idreesaesp. nov. The genus is reported for the first time in the Eastern province of the KSA. This is the first host-parasitoid association for Microplitis documented in the country. The new species attacks Mythimna Ochsenheimer (Lepidoptera, Noctuidae). Natural history information is provided such as the association of males with females, geographical location, possible food plants, and details of wasp cocoons. In addition, a fragment of the mitochondrial cytochrome b gene is presented. A taxonomic key to the species of Microplitis reported from the KSA is provided. Characters of this new species and its affinities with the three previous species described from the KSA and four of the closely related to Palaeartic species are also discussed.

In social vespine wasps, the nest characteristics and associates vary intra- and interspecifically. I studied the nest characteristics and nest associates of three Dolichovespula wasp species in boreal Finland. The average number of combs and cells per nest was similar among D. media , D. saxonica and D. norwegica , and similar to Dolichovespula in the temperate zone. Most D. media and D. saxonica colonies produced both gynes and males, whereas D. norwegica produced mainly either one. The average colony lifespan of D. saxonica was a bit over two months, i.e. shorter than documented for Dolichovespula in the temperate zone. The proportion of nests parasitised by the ichneumonid wasp Sphecophaga vesparum was 36% in D. saxonica and 50% in D. media ; S. vesparum has not been recorded from D. media before. The proportion of parasitized cells was 0.6–11% for D. saxonica and 0.2–22% for D. media . The proportion yellow, overwintering cocoons of S. vesparum was highly variable among the nests. The proportion of nests parasitised by the moth Aphomia sociella was 36% in D. saxonica and 13% in D. media . Sphecophaga and Aphomia were not recorded from D. norwegica colonies, which supports studies in the temperate zone. The study adds up to the previous research on the nest structure and nest associates of vespines, and together they indicate that there is geographical variation within Europe and globally in the host use of Sphecophaga .

The study adds up to the previous research on the nest structure and nest associates of vespines, and together they indicate that there is geographical variation within Europe and globally in the host use of Sphecophaga .","PeriodicalId":50185,"journal":{"name":"Journal of Hymenoptera Research","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136195358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
