The relationship between the subtribes Lignyodina and Tychiina of Tychiini were tested on basis morphological characters from immature stages. mature larvae Lignyodes bischoffi (Blatchley, 1916) L. enucleator (Panzer, 1798) (Curculionidae, Curculioninae, Tychiini, Lignyodina) pupae are described in detail for first time. To be sure about correct taxonomic identification larvae, DNA sequences obtained compared both adults these two species. Molecular data show that studied species Dejean,...
The genus Lalagetes Schoenherr, 1842 is redefined, compared with related genera and all known species placed among three genera. Four new from South Africa are described: L. andersoni sp. nov. (Mpumalanga), howdenorum (Limpopo), sarkae (KwaZulu-Natal) zitae (KwaZulu-Natal). Lectotypes of seminulum Fåhraeus, 1871 subfasciatus Boheman, designated here, both redescribed. All the following keyed illustrated. combinations proposed: Glyptosomus edax (Marshall, 1939), G. inaequalis 1941), leurops...
The genus Pselactus in the Cape Verde Islands is reviewed. obesulus (Wollaston, 1867) from São Vicente redescribed and P. strakai sp. nov. Nicolau described. Both species are diagnosed illustrated; their larvae described, larval morphology discussed current state of knowledge about immature stages Cossoninae summarized. systematic position within Onycholipini reviewed, placement discussed. A short note on biogeography provided.
Two new genera, Barclayanthus Borovec Skuhrovec, gen. nov. and Janakius nov., assigned to the tribe Trachyphloeini Lacordaire, 1863, are described for three South African species of weevil: micros sp. B. cooteri sylvaticus All illustrated keyed. The taxonomic status each genera is discussed, compared with similar Embrithini Marshall, 1942. A key known small terricolous both included.
The larva and the pupa of Palaearctic weevil species Tychius subsulcatus Tournier, 1847 are described illustrated for first time. characters T. completely fit differential diagnosis subtribe Tychiina, genus Tychius, also intrusus group. Astragalus onobrychis Linnaeus is confirmed as its host plant. biology in south Slovakia (Cerová vrchovina Mts.) described.
Two values of thermal requirements, the lower developmental threshold (LDT), that is, temperature at which development ceases, and sum effective temperatures, day degrees above LDT control ectotherms are used in phenology models to predict time individual stages a species will be completed. To assist rapid models, we merged previously published database requirements for insects, gathered by online search CAB Abstracts, with independently collected data insects mites from original studies....
The Afrotropical species described as Trachyphloeini Lacordaire, 1863 were examined and their taxonomic status is revised. Atrachyphloeus Voss, 1962 proposed a junior synonym of Phaylomerinthus Schoenherr, 1842, Cathormiocerus africanus Hoffmann, 1965 Tapinomorphus sylvicola Trachyphloeus pustulifer 1959 Platycopes tuberculatus Marshall, 1906. convergens transferred to the genus hardenbergi 1923 T. notulatus Boheman, 1842 Glyptosomus 1847, nanus Fåhraeus, 1871 Pentatrachyphloeus 1974, 1823...
A new genus and species of the subfamily Cossoninae, Omanocossonus sabulosus gen. et sp. nov. is described from Oman. All specimens including larvae were found on sand dunes seashore in roots Calotropis procera (Aiton) W.T. Aiton. The crucial features, male female terminalia, are illustrated, taxonomic position within Cossoninae briefly discussed. generic status Lindbergius Roudier, 1957 resurrected. mature larva described, larval morphology discussed current state knowledge about immature...
Abstract Carabids are generalist predators that contribute to the agricultural ecosystem service of seedbank regulation via weed seed predation. To facilitate adoption this services by farmers, knowledge predation and resilience with co-varying availability alternative prey is crucial. Using assessments on cards in 57 cereal fields across Europe, we demonstrate a regulatory effect soil seedbank, at continental scale, groups formed omnivore, seed-eating (granivore + omnivore) all species...
We envisage a future research environment where digital data on species interactions are easily accessible and comprehensively cover all species, life stages habitats. To achieve this goal, we need from many sources, including the largely untapped potential of citizen science for mobilising utilising existing information interactions. Traditionally volunteers contributing occurrence have focused single‐species observations within one target taxon. make recommendations how to improve...
Abstract Predatory larvae of the lacewing Chrysoperla carnea (Neuroptera: Chrysopidae) represent an important biocontrol agent, as they prey on a wide range prey, including economically crop pests. However, some use active defensive behaviours that may reduce effectiveness these predators in biological control. In this study, we aimed to investigate anti‐predator behaviour two pests, Scrobipalpa cf. ocellatella and Autographa gamma (Lepidoptera: Gelechiidae Noctuidae, respectively),...
Abstract Glyphosate is the number one herbicide in world. We investigated sub-lethal effects of this on aphid Metopolophium dirhodum (Walker), using an age-stage, two-sex life table approach. Three concentrations (low - 33.5, medium 66.9 and high 133.8 mmol dm −3 active ingredient) distilled water as control were used. The LC 50 IPA salt glyphosate M. was equivalent to 174.9 ingredient (CI 95 : 153.0, 199.0). population parameters significantly negatively affected by application, negative...
We tested whether two basic thermal requirements for insect development, lower developmental thresholds, i.e. temperatures at which development ceases, and sums of effective temperatures, numbers day degrees above the thresholds necessary to complete differ among species that proved be successful invaders in regions outside their native range those did not. Focusing on traits underlying invasiveness are related temperature provides insights into mechanisms invasions. The screening thus could...
Larvae of 14 species and pupae 12 Palaearctic Tychius Germar, 1817 are described for the first time. T.meliloti Stephens, 1831, T. squamulatus Gyllenhal, 1835 quinquepunctatus (Linnaeus, 1758), redescribed with addition new characters. They belong to 10 22 groups assembled through adult morphological characters in this region and, like all other known biology, studied live on Leguminosae Papilionoideae, belonging tribes Genisteae, Loteae, Galegeae, Trifolieae Vicieae. Generally larvae, but...
The type and intensity of plant-herbivore interactions are likely to be altered under climate change as a consequence differential dispersal rates plants their herbivores. Here, we studied variation in herbivore damage on Salvia nubicola the field compared its growth defence strategies against herbivores controlled conditions using seeds from populations along broad altitudinal gradient. Our work is one first studies simultaneously measure complex intraspecific plant growth, direct indirect...
Abstract Intensified agriculture, a driver of biodiversity loss, can diminish ecosystem functions and their stability. Biodiversity increase functional redundancy is expected to stabilize functions. Few studies, however, have explored how agricultural intensity affects its link with function Here, within continental‐wide study, we assess seed predation affected by landscape simplification. By combining carabid abundances molecular gut content data, was quantified for 65 weed genera across 60...
