Aerobic Metabolism Alterations as an Evidence of Underlying Deltamethrin Resistance Mechanisms in Triatoma infestans (Hemiptera: Reduviidae)
(Entomological Society of America, 2020-06)Triatoma infestans (Klug, 1834), the main vector of Chagas disease in Latin America, is regularly controlled by spraying the pyrethroid deltamethrin, to which some populations have developed resistance. The three main ... -
Aggressive tree killer or natural thinning agent? Assessing the impacts of a globally important forest insect
(Elsevier, 2021-03)Invasive insects and pathogens are prominent tree mortality agents in forests around the world, and the magnitude of their impacts is increasing. Comparative studies across multiple populations can be helpful for the ... -
Cumulative effects of volcanic ash on the food preferences of 2 Orthopteran species
(2017)Los polvos inertes son una forma temprana de insecticida que todavía está en uso. Uno de los polvos inertes más comunes es la ceniza volcánica. Con el fin de estudiar la reacción de saltamontes de pastizales, Dichroplus ... -
Drivers of global Scolytinae invasion patterns
(Ecological Society of America, 2020-02)Biological invasions are affected by characteristics of invading species, strength of pathway connectivity among world regions and habitat characteristics of invaded regions. These factors may interact in complex ways to ... -
Drosophila suzukii (Diptera: Drosophilidae) distribution modelling improves our understanding of pest range limits
(Taylor & Francis, 2019)Spatial distributions models (SDM) are often used in invasive pest management to understand current and potential distribution. Using data on the well-studied spotted wing drosophila as a model, we compared distribution ... -
Effect of Drosophila suzukii on Blueberry VOC’s: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae
(Springer, 2021-07)Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to find their hosts. However, this chemical landscape may be altered by the invasion of exotic insect ... -
Effect of plant nutritional traits on the diet of grasshoppers in a wetland of Northern Patagonia
(Taylor & Francis, 2020-05)Dichroplus maculipennis is one of the most damaging grasshoppers of wetlands. We investigated their feeding behavior in relation to the most abundant plants of Patagonian wetlands. Results showed that D. maculipennis was ... -
Effect of vegetable oils as Phagostimulants in adults of Dichroplus vittigerum (Orthoptera: Acrididae)
(Entomological Society of America, 2019-12)Several species of grasshoppers are attracted to vegetable oils. These oils have kairomonal properties mainly due to the presence of linolenic and linoleic fatty acids. This study aimed to determine whether the odors of ... -
Estimation and analysis of insect population dynamics parameters via physiologically based models and hybrid genetic algorithm MCMC methods
(Elsevier, 2023-11)Decision support systems are gaining importance in several fields of agriculture, forest, and ecological systems management. Their predictive potential, entrusted to mathematical models, is of fundamental importance to set ... -
Factors affecting success of galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) = Factores que afectan el éxito de las agallas de Aditrochus coihuensis (Hymenoptera: Pteromalidae)
(Sociedad Entomológica Argentina, 2011-12)Galls of Aditrochus coihuensis (Hymenoptera: Pteromalidae) were collected from their host tree, the southern beech Nothofagus dombeyi, near San Carlos de Bariloche, Argentina, during the spring of 2007. Galls were carefully ... -
Factors driving historic intercontinental invasions of European pine bark beetles
(Springer, 2022-06)Largely assisted by global trade, alien insect species are being introduced into new territories at unprecedented rates. Among forest insects, pine bark beetles (Coleoptera: Curculionidae, Scolytinae) are a large and diverse ... -
First detection of the cosmopolitan invader Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) in Argentina
(Academia Brasileira de Ciências, 2019-08-12)Leptoglossus occidentalis Heidemann is a conifer seed bug, native to North America. This species is considered invasive and has reached several countries in the Northern Hemisphere and most recently Chile in South America. ... -
First study of host-plant preferences of Sinopla perpunctatus (Hemiptera: Acanthosomatidae), a stink bug from the Andean-Patagonic forest
(Florida Entomological Society, 2014-06)Host plants of phytophagous insects are not equally attractive. The aim of this study was to evaluate the host-plant behavior of Sinopla perpunctatus Signoret (Hemiptera: Acanthosomatidae) and determine which parameters ... -
Flexible foraging decisions made by workers of the social wasp Vespula germanica (Hymenoptera: Vespidae) in response to different resources: influence of ontogenetic shifts and colony feedback
(Wiley, 2022-04)Decisions made by foraging animals conform a complex process based on the integration of information from multiple external environmental stimuli and internal physiological signals, which in turn are modulated by individual ... -
Foraging niche separation of social wasps in an invaded area: Implications for their management
(Wiley Online Library, 2019-10)Foraging niche separation may be a mechanism to promote coexistence of two competing species by concentrating intraspecific competition relative to interspecific competition. The present study investigated foraging behaviour ... -
Forest Health in the Southern Cone of America: State of the Art and Perspectives on Regional Efforts
(MDPI, 2023-04)The plantation and natural forests of South America have been highly impacted by native and exotic pests in recent decades. The interaction of emerging invasive pests, climate change, and timber markets will define the ... -
Genetic assessment of the invasion history of Drosophila suzukii in Argentina
(Springer Nature, 2019-08)Drosophila suzukii (Diptera: Drosophilidae) is a highly polyphagous fruit pest native to eastern Asia, which in the last decade had widely expanded its range and become a serious pest in the Americas and Europe. Invasion ... -
Habituation in mosquito larvae Aedes aegypti is context-specific
(The Company Biologists, 2021-06)Mosquito larvae live in water and perform a stereotyped escape response when a moving object projects its shadow on the surface, indicating potential risk of predation. Repeated presentations of the shadow induce a decrease ... -
Host genetics determines food preferences of the moth Perzelia arda (Lepidoptera: Depressariidae)
