Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)
(Springer, 2022-07-03)In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species can have a strong ... -
Managing nuisance social insects in urban environments : an overview
(2017-04)Urbanization is progressing worldwide where social insects often attain pest status. We present an overview of the practices applied for the management of social insects in urban settings from 1990 to 2016. We found that ... -
Mate-searching behavior in the invasive German wasp, Vespula germanica, in Patagonia
(John Wiley & Sons Ltd, 2018-07)In order to increase the probability of reproduction, social insects can adopt various mate‐finding strategies, such as increasing densities of males at specific locations, and/or visual and chemical cues that attract the ... -
Neo-sex chromosomes in the Masculipennis species group (Dichroplus: Acrididae, Melanoplinae) : the cases of D. masculipennis and D. vittigerum
(2016)Los saltamontes de melanoplina de América del Sur muestran un número desproporcionado de cariotipos derivados, incluyendo muchos casos de sistemas cromosómicos neo-sexuales. Esto es especialmente cierto para el género ... -
Pest management of social insects in urban settings
(2017-04)Pest management of social insects in urban environments is a growing global concern, given the problems that these pests generate and the growth of urban areas worldwide. In this special issue, we present studies on the ... -
Population ecology and classical biological control of forest insect pests in a changing world
(Elsevier, 2022-09-15)Forests are important for climate regulation and provide wood and fiber to an increasing human population. Forest systems encompass a large part of the world’s land surface area and they are increasingly threatened by ... -
The role of leaf cellulose content in determining host plant preferences of three defoliating insects present in the Andean-Patagonian forest
(2016)Los insectos fitófagos eligen sus recursos alimenticios según sus propias necesidades además de las propiedades de las plantas huésped, como las defensas biomecánicas. Las preferencias alimentarias de los insectos folívoros ... -
Sex, life history and morphology drive individual variation in flight performance of an insect parasitoid
(2017-08)1. The movement of organisms can be driven by multiple factors and has implications for fitness and the spatial distribution of populations. Insects spend a large proportion of their adult lives foraging by flying for ... -
Structure and composition of a thrips community in the Chihuahua Desert, New Mexico, U.S.
(Florida Entomological Society, 2012-03)We examined plant used versus plant availability by a thysanopteran community on 13 woody and perennial native plants in the Chihuahua Desert. Individual plants were sampled with sticky-traps on 8 dates from May 1997 to ... -
Substrates Preference for Pupation on Sawfly Notofenusa surosa (Hymenoptera: Tenthredinidae)
(Springer, 2015-05)The choices made by insects at different stages of their life cycle are critical for the individual and progeny success. In the case of leaf-miners, during larval development they are not able to make choices until the ... -
Temperature and host plant species affect the performance and immunocompetence of an outbreak defoliator in northwestern Patagonia
(Royal Entomological Society, 2022-03)1. Rising temperature has been associated with increased occurrence of herbivorous insect outbreaks, explained by several direct and indirect mechanisms. Whereas natural enemies are known key drivers of forest-defoliating ... -
Worldwide diversity of endophytic fungi and insects associated with dormant tree twigs
(Springer, 2022-03)International trade in plants and climate change are two of the main factors causing damaging tree pests (i.e. fungi and insects) to spread into new areas. To mitigate these risks, a large-scale assessment of tree-associated ...
