In this paper we report two aphid species as new records for the Greek and the European aphid fauna. The species are Aphis odinae (van der Goot) and Melanaphis sorghi (Theobald) (Hemiptera: Aphididae). The former was found on Pittosporum spp. in Thessaloniki, northern Greece, and the latter on Sorghum halepense (L.) in Messolonghi, southern Greece, and also in Thessaloniki. Heavy infestations in Pittosporum trees by A. odinae have not been observed and M. sorghi was not detected in cultivated sorghum or maize in the few inspections we made. Thus, according to our inspections neither of these species is as yet of economic importance in Greece. These two species increase the number of aphid species recorded in Greece to 335.

 Several papers have been published on aphid fauna in Greece during the last two decades, but the number of recorded species is still low compared to other European countries, including some from the Mediterranean basin. In this context, we collected aphids from various host-plants and regions in southern, central and northern Greece characterized by diverse flora, climatic conditions and ecological habitats. In total, 128 aphid species belonging to 55 genera and six subfamilies were collected on 200 host-species. Most of the species dominated the subfamily Aphidinae (especially tribes Macrosiphini and Aphidini). Among the species collected, 18 were new records in Greece. The present work improves our knowledge regarding the aphid fauna of Greece and suggests that the number of recorded species could increase further if additional studies were undertaken.

Several stink bugs in the subfamily Pentatominae are crop pests or have the potential to damage plants of economic importance. In the Brazilian state of Rio Grande do Sul, where agriculture plays a major role in the economy, the knowledge about pest stink bugs is fragmented and, in some instances, outdated. This work provides a summary of Pentatominae species recorded in Rio Grande do Sul feeding on the four most important grain crops for the state, i.e. soybean, rice, maize, and wheat, plus canola, an emerging crop. This survey is enhanced with new records from scientific collections, a short diagnosis for each species, distribution maps, an identification key, and carefully illustrated to allow for species recognition in the field. With this work, we aim to reunite the scattered knowledge of the group in one single revision, and provide a useful tool for identifying the pest stink bugs of Rio Grande do Sul.

Chloropidae are of major economic importance, since the larvae of some species are pests of cereals and grasses, some are parasitoids and predators, and adults of some Hippelates spp. visit and transmit or are suspected of transmitting yaws sores in man and animals and by feeding around the eyes are vectors of Brazilian Purpuric Fever. Within the framework of the exploration of the biodiversity of Diptera in Southwest Saudi Arabia a survey of the grass flies fauna in 18 sites in Jazan, Asir, and Najran in south-western Saudi Arabia was performed mainly using Malaise traps and sweep nets from 2010– to 2016. Sixty six species of 43 genera and three subfamilies of Chloropidae were identified and are recorded from Saudi Arabia, 20 of them for the first time and three are described as new species: Elachiptera arabica Deeming sp. n.; Kwarea ismayi Deeming sp.n. and Tricimba turneri Deeming sp.n.. This makes the total number of Chloropidae species in Saudi Arabia 95 (including 29 species previously recorded). Seventy images are presented. The species of Chloropidae listed are predominantly of Afrotropical/ Palaearctic origin. An updated checklist of Chloropidae species of Saudi Arabia is presented.This study adds new records of Chloropidae to the Saudi Arabian Diptera fauna, which will become reference points for research detailing the systematic geographic distribution and for identifying other specimens submitted for identification. Further species will undoubtedly be discovered with more research involving collecting and rearing methods.

Economic Use

Red algae are the most conspicuous component in algal drifts that periodically arrive on the coasts of the Yucatan Peninsula. Given the presence of agars and carrageenans in their cell wall and the synthesis of secondary metabolites that act as antitumors or antioxidants, most of these species are highly valued in the international market. However, in this region of Mexico they are not used but represent a problem of waste from beaches. Our aim was to determine the composition of marine red algae of economic use in the algal drifts of the Yucatan Peninsula, providing brief descriptions, photographs that facilitate their identification and possible explanations for their causes and routes of origin. 13 samplings were carried out at 14 sites, collecting fresh and complete thalli from which the species of economic importance were described. 24 species distributed in six orders and seven families were identified. The most abundant families for both the number of species and the amount of biomass were Gracilariaceae (10 species), Rhodomelaceae (6 species) and Solieriaceae (3 species). The localities with the greatest diversity and biomass were those belonging to Campeche: Sabancuy (11 species), Punta Xen (14 species), Tortuga Bay (13 species) and Playa Bonita (13 species). From the present study we contributed six new records endemic to Campeche, including the first record of the genus Codiophyllum for the Western Atlantic Ocean. Our data on diversity, biomass, periodicity and growth rates of red algal drifts allow us to suggest that the Campeche and Yucatan drifts are a sustainable source of raw material.

The present study is based on the specimens of Acridoidea during the course of a survey (1993–1996) from various agricutural areas of different regions of Fezzan. Nearly 4,230 specimens were collected from 68 localities and identified down to specific level. From this 50 species of Acridoidea representing 28 genera and 3 families of Acridoidea were identified. Their distinguishing characters and economic importance are given. Bio-ecological data on the species and their relationship with vegetation are also provided. A key to the genera examined is provided. Furthermore, the data resulting from the survey established new records for genera and species of Acridoidea previouly known to occur elsewhere in the country and many new localities recorded for others. Among the present material from Fezzan, fifteen genera, twenty-seven species, and eight subspecies are recorded for the first time. Also, three species and three subspecies are reported for the first time from Libya.

Cereal Cultivation

When, and by what route, did farming first reach Europe? A terrestrial model might envisage a gradual advance around the northern fringes of the Aegean, reaching Thrace and Macedonia before continuing southwards to Thessaly and the Peloponnese. New dates from Franchthi Cave in southern Greece, reported here, cast doubt on such a model, indicating that cereal cultivation, involving newly introduced crop species, began during the first half of the seventh millennium BC. This is earlier than in northern Greece and several centuries earlier than in Bulgaria, and suggests that farming spread to south-eastern Europe by a number of different routes, including potentially a maritime, island-hopping connection across the Aegean Sea. The results also illustrate the continuing importance of key sites such as Franchthi to our understanding of the European Neolithic transition, and the additional insights that can emerge from the application of new dating projects to these sites.

Hymenopteran Parasitoids

Despite their ecological and economic importance, hymenopteran parasitoids are severely understudied. Even in countries with a long taxonomic history such as Germany, dating back to the 18th century and including prolific figures like Christian Gottfired Nees von Esenbeck and Otto Schmiedeknecht, those species-rich groups are seldom the subject of comprehensive research efforts, leaving their true diversity unknown. This is often due to their small size of a few millimetres on average, leading to difficulties in their identification and examination. The chalcidoid family Pteromalidae is no exception to this neglect. So far, 735 species have been reported from Germany. Estimating the diversity of this group is not possible, but it has to be assumed that many more species are still to be discovered in Germany. With this study, we improve the knowledge on pteromalid diversity and present new records of 17 genera and 41 species, previously unknown to occur in Germany. We also match and describe previously unknown sexes of two species, based on DNA barcode data. The results of this study were generated as part of the German Barcode of Life Project. The newly-recorded species are illustrated and notes on the biology and distribution are given. The ecological significance of Pteromalidae and potential value as indicators for nature conservation efforts are briefly discussed.

Aphid species abundance was studied by means of yellow Moericke water traps in several tobacco fields in two tobacco growing areas, Aitoloakarnania and Pieria, Greece. In 1992, from alate catches, in three different localities in Aitoloakarnania, a total number of 69, 40 and 31 taxa were caught and identified. Five of them are new records for the Greek aphidofauna. In 1993, from the traps established near Agrinio and in Nea Ephessos, Pieria, a total number of 55 and 139 aphid taxa were caught and identified. Twenty one of them aphid species are new records for Greece of which 3 had been already recorded in the previous year. In total, 23 aphid species recorded for the first time in Greece are presented in this work.
