Novel repellents for the blood-sucking insects Rhodnius prolixus and Triatoma infestans, vectors of Chagas disease
(BioMed Central, 2020-03)
Background: Studying the behavioral response of blood-sucking disease-vector insects to potentially repellent volatile compounds could shed light on the development of new control strategies. Volatiles released by human ...
Insect Trace Fossil Associations in Paleosols: The Coprinisphaera Ichnofacies
(Society for Sedimentary Geology, 2000-02)
Analysis of fifty-eight paleosol trace fossil assemblages, ranging from the Triassic to the Recent, allows refinement of continental ichnofacies models and the proposal of a Coprinisphaera ichnofacies. The Coprinisphaera ...
Masting has different effects on seed predation by insects and birds in antarctic beech forests with no influence of forest management
(2017-09-15)
Mast seeding is characteristic of many long-lived tree species and widely proposed as a mechanism to reduce seed predation. However, whether the efficiency of this reproductive response may vary depending on type of seed ...
The fat body of the hematophagous insect, panstrongylus megistus (Hemiptera: Reduviidae): Histological features and participation of the β-chain of ATP synthase in the lipophorin-mediated lipid transfer
(University of Arizona, 2019-07)
In insects, lipid transfer to the tissues is mediated by lipophorin, the major circulating lipoprotein, mainly through a nonendocytic pathway involving docking receptors. Currently, the role of such receptors in lipid ...
The limpet transcription factors of Triatoma infestans regulate the response to fungal infection and modulate the expression pattern of defensin genes
(Elsevier Science, 2019-05)
As part of the innate humoral response to microbial attack, insects activate the expression of antimicrobial peptides (AMP). Understanding the regulatory mechanisms of this response in the Chagas disease vector Triatoma ...
Insects moving through forest-crop edges: a comparison among sampling methods
(Springer, 2020-04)
Edges between natural and cultivated habitats have become dominant elements of all terrestrial ecosystems. Interchanges of several groups of organisms, such as insects, occur through these edges, potentially affecting ...
Firewood as a pathway for insect introductions. What are the risks of ant invasions in Patagonia?La leña como vía para la introducción de insectos. ¿Cuáles son los riesgos de las invasiones de hormigas en la Patagonia?
(Asociación Argentina de Ecología, 2017-08)
La leña puede actuar como vector de dispersión de insectos a larga distancia, tanto dentro como entre países. Recientemente encontramos en Patagonia a la hormiga carpintera exótica Camponotus mus en leña transportada desde ...
Insect and plant traits drive local and landscape effects on herbivory in grassland fragments
(Wiley-Blackwell, 2019-05)
Herbivory is one of the most important antagonistic insect-plant interactions and can be influenced by factors at local and landscape scales. Landscape fragmentation may reduce herbivory directly (i.e., decreasing abundance ...
How Did Seal Lice Turn into the Only Truly Marine Insects?
(MDPI AG, 2021-12)
Insects are the most evolutionarily and ecologically successful group of living animals, being present in almost all possible mainland habitats; however, they are virtually absent in the ocean, which constitutes more than ...
High Prevalence of a Newly DiscoveredWutai Mosquito Phasivirus in Mosquitoes from Rio de Janeiro, Brazil
(Multidisciplinary Digital Publishing Institute, 2019-05)
Many RNA viruses have recently emerged, threatening humans and causing harm to animals and plants. Bunyaviruses represent one of the largest groups of RNA viruses and are able to infect a wide range of hosts (invertebrates, ...
