... Wireworms, the larvae of click beetles are world-wide pests of arable and vegetable crops. Many studies have shown that arthropods are influenced by landscape context. Therefore, for successful wireworm risk assessment, it is important to gain more information on relationships between landscape structure and wireworm infestation level. The aim of this study was to investigate if different landscap ...
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC. These exp ...
Elateridae; aggregation pheromones; attractants; integrated pest management; sex pheromones
Abstract:
... The study of pheromones of click beetles was started with the objective of applying similar methods in IPM strategies for the control of wireworms, based on the similar experience gained from the widely used moth pheromones. A brief overview is presented on the identification of click beetle pheromones, new questions arising in the categorization of these pheromones into sex or aggregation pheromo ...
... Nine species of phoretic mesostigmatid mites are recorded on twelve species of beetles (Coleoptera: Carabidae, Cerambycidae, Elateridae, Erotylidae, Scolytinae). The most numerous species of insects on which mites were found were Carabus granulatus (91 specimens of mites) and Plagionotus detritus (67). The most numerous mites were Iphidosoma fimetarium (100 specimens) and Trichouropoda sociata (77 ...
... Soil‐dwelling insects commonly co‐occur and feed simultaneously on belowground plant parts, yet patterns of damage and consequences for plant and insect performance remain poorly characterized. We tested how two species of root‐feeding insects affect the performance of a perennial plant and the mass and survival of both conspecific and heterospecific insects. Because root damage is expected to imp ...
Elateridae; new genus; scientific illustration; taxon descriptions; Chile
Abstract:
... Tunon gen. nov., a new genus of Protelaterini from southern Chile is here described and illustrated with one species Tunon guinezi sp. nov. Its relationships with other members of the Protelaterini such as the Chilean genera Anaspasis Candèze 1881 and Valdivelater Lawrence & Arias 2009 are discussed. ...
... Wireworms in Florida are primarily a pest in newly planted sugarcane, and growers usually apply a soil insecticide at planting to protect germinating seedpieces from wireworm damage. However, studies have suggested that this application in many cases may not be necessary. The objective of this research was to test a sequential sampling method to determine the need for soil insecticide at sugarcane ...
... The species composition, abundance and, vertical distribution of Collembola (53 species), Lumbricidae (6 species), and Elateridae (12 species) are estimated in alluvial soils of the middle taiga floodplain forests. The significance of individual species in the formation of invertebrates communities in different biotopes are demonstrated, species that are adapted to high humidity are revealed. Inve ...
... We describe the results of four laboratory studies designed to measure the effect of temperature and wireworm appetence, weight, and degree of Metarhizium infection on their ability to damage wheat seedlings. Wireworm activity, measured from wireworm speed, increased linearly from 6 to 18 °C and leveled off thereafter. Plant emergence and growth increased exponentially from 6 to 22 °C for wheat cu ...
... This paper contains a review of beetle species (Coleoptera) described from Baltic amber. The compiled checklist contains 434 species from 149 extinct and 138 extant genera. At this moment, 90 families are registered. The best known and therefore most diverse families are: Staphylinidae (77 described spp.), Curculionidae (46 spp.), Carabidae (32 spp.), Scirtidae (21 spp.), Cleridae (17 spp.), Elate ...
... Forests support high concentrations of species and beetles in particular are often used to evaluate forest biodiversity. Ancient pasture woodlands are facing a major decline in Europe mainly due to the abandonment of traditional management and subsequent succession. We studied click beetles (Coleoptera: Elateridae) in one of the largest central-European remnants of pasture woodland in Lány Game Pa ...
