This investigation involved analyzing 77 publications, 6 national biological collections and an international collection and determining the myrmecological diversity of Tamaulipas, which consists of 195 species that belong to 60 genera, with 410 records in the state. The genera with the highest species richness were Camponotus Mayr (Formicinae), Pheidole Westwood (Myrmicinae) and Neivamyrmex Borgmeier (Dorylinae), with 17, 15 and 12 species, respectively. The ant fauna of Tamaulipas consists of 95% native species and 5% exotic species. The investigation determined that 25 municipalities had been sampled, and Gómez Farías, Victoria and Jaumave stood out with the highest number of ant species records; however, 18 municipalities that provide opportunities to increase the knowledge of Formicidae remain unexplored.

The Psyllidae family is the most diverse within Psylloidea, with more than 1,300 species worldwide. Some psyllid species are important pests mainly of fruit trees, forest and ornamental plants. Despite being an economically relevant group, there are few studies on its biology, geographic distribution, natural enemies or host plant associations for many Argentinean psyllid species. This work records one species from Argentina for the first time, extends the distribution of another two psyllid species and provides information on host plants.

The genus Athetis Hübner (Lepidoptera. Noctuidae. Amphipyrinae) comprises numerous species worldwide, two of them recently reported as pests of maize in China. This work presents the first record of an Athetis species feeding on soybean in the eastern region of the province of Córdoba, Argentina. The specimens were identified as Athetis rionegrensis status rev. based on external morphology and genitalia characters for both sexes. Furthermore, additional specimens were collected in the province of La Pampa, Argentina, on October, 2021.This species was only known to be in Alto Valle, province of Río Negro, Argentina, therefore these specimens represent the first record of the species outside that province. The correct assignment of this species to the Athetis genus is confirmed. Finally, the implications of this new record are discussed.

Spiders have been used to evaluate changes in systems by anthropization effect, some species showing sensitivity to gradual and drastic changes such as urbanization, and other species have been documented as tolerant to this effect. The goal of this work was to describe the change in the spider community in relation to the age of buildings. at the west of Morelia, Michoacán, Mexico. Three categories of construction time and the neighboring vegetation as the pre-urbanization environment were used for comparison. Using direct capture, pit-fall traps and beating nets, 3,619 spiders were collected, and 3,219 (315 males, 630 females and 2,274 immatures) were used for the analysis after removal juveniles that was not possible to identify. A total of 28 families, 93 genera, 47 species and 55 morphospecies were identified. This represents the greatest richness and abundance recorded in urban environments of the country. It describes changes in alpha diversity from colonization in recent constructions to those built 17 years ago. I t was observed that abundance, richness, and diversity decrease with the age of a building, but with high equitability in every age of construction. The age of a building is an important factor for the process of succession in urban environments.

Exclusive to the Neotropical region, leaf cutter ants are considered agricultural pests, although they can also have a positive effect on plants. In Mendoza vineyards, vegetal biodiversity is minimal, therefore they cut off this plant as a feeding resource. Acromyrmex lobicornis Emery it is mostly nocturnal and forages according to temperature. Foraging and maintenance activity was measured monthly in 14 colonies, throughout a full day at fourhour intervals, from October 2019 to March 2020. Acromyrmex lobicornis showed different seasonal patterns of foraging activity. Foraging intensity was highest throughout January and February, intermediate during December, and lowest in October and November. A bimodal feeding pattern was observed, foraging both day and night avoiding the hottest hours. The maximum collection of fragments was observed in the range of 10 and 19 °C, less between 20 - 39 °C, minimum between 40 - 49 °C and null between 0 - 9 °C. The nest - maintenance activity was maximum between 20 - 29 °C, less between 30 - 39 ° C, minimum between 40 - 49 °C and null between 0 - 20 °C.

The aims of this study were to identify and estimate the potential pollinators of Fragaria ananassa Duch. “strawberry”, through the analysis of pollen carried out on their bodies. The study was carried out on a commercial farm in Las Pampitas, located in the Perico valleys, Jujuy province (Argentina). Floral visitors and other arthropods were sampled and identified, and their diversity was analyzed. The samples of insects selected to obtain the pollen carried were processed following the acetolysis technique. The potential pollinators of the strawberry crop were estimated by calculating the pollination probability index. The floral visitors corresponded to representatives of Hymenoptera, Diptera, Hemiptera, Lepidoptera, Coleoptera and even Araneae. Apis mellifera L. was the most frequent floral visitor and presented more strawberry pollen than other selected insects. The pollination probability index estimated that this species had a high probability of being a pollinator. Other pollinators such as Allograpta exotica Wiedemann, Halictidae, Meliponini and even Thripidae could complement the action of the honeybee. This is the first contribution to the knowledge of the pollination of F. ananassa in the agroecosystems of Jujuy.

The objectives of this study are to identify thrips and their biological controllers, to analyze their abundance in three flower opening stages stages of chrysanthemum crops, and to determine alpha and beta diversity in two ecoregions of Jujuy province (Argentina). The study was carried out in the Chaco ecoregion (ECH) in October and November 2016, and in the Prepuna ecoregion (EP) in February and March 2018. On each date, six replicates of five flowers were excised in the stages: flower bud , semi-open flower and open flower. Diversity profiles and rank-abundance curves were built, and Jaccard's coefficient of similarity was applied. The diversity profiles showed significant differences in thrips communities. In the ECH, 15 thrips species were identified; the dominant and permanent species were Microcephalothrips abdominalis (Crawford) and Frankliniella occidentalis (Pergande). Five species were recorded in the EP, although Frankliniella gemina Bagnall and Thrips tabaci Lindeman on their own represented 78% of the total abundance. In the ECH, 20 entomophagous species/morphospecies were recognized, and 19 in the EP; antocorids were dominant in both ecoregions. The thrips and the entomophagous communities of chrysanthemum flowers were different (34%) between the ecoregions studied.

Five species were recorded in the EP, although Frankliniella gemina Bagnall and Thrips tabaci Lindeman on their own represented 78% of the total abundance. In the ECH, 20 entomophagous species/morphospecies were recognized, and 19 in the EP; antocorids were dominant in both ecoregions. The thrips and the entomophagous communities of chrysanthemum flowers were different (34%) between the ecoregions studied.","PeriodicalId":54250,"journal":{"name":"Revista De La Sociedad Entomologica Argentina","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47023391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
