Clave dicotómica para especies parasitoides e hiperparasitoides (Hymenoptera) de áfidos (Hemiptera: Aphididae) de Costa Rica

Agronomía Mesoamericana, 2017
Los áfidos representan una problemática para muchas especies de plantas, debido a que son vectores de múltiples patógenos; el control biológico mediante el uso de parasitoides es una opción permanente de control de sus poblaciones.

Estudio de la biología del bicho de cesto y los parasitoides asociados en el caldenal

Semiárida, 2018
Desde el año 2006 se observa una invasión creciente de Oiketicus platensis (Berg 1883) en los bosques de caldén de la provincia de La Pampa. Los objetivos del presente trabajo son: 1) relevar la comunidad de parasitoides larvales, 2) determinar la época ...

Stable pollination service in a generalist high Arctic community despite the warming climate. [PDF]

Ecol Monogr, 2023
Abstract Insects provide key pollination services in most terrestrial biomes, but this service depends on a multistep interaction between insect and plant. An insect needs to visit a flower, receive pollen from the anthers, move to another conspecific flower, and finally deposit the pollen on a receptive stigma.

Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]

New Phytol
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Anomalous latitudinal gradients in parasitoid wasp diversity-Hotspots in regions with larger temperature range. [PDF]

J Anim Ecol
Using the largest georeferenced molecular dataset for ichneumonoid parasitoid wasps, we implemented a macrogenetics approach to examine latitudinal patterns and predictors of intraspecific genetic diversity and explain the global distribution of genetic diversity in this group.

Multiple facets of biodiversity are threatened by mining‐induced land‐use change in the Brazilian Amazon

Diversity and Distributions, Volume 29, Issue 9, Page 1190-1204, September 2023., 2023
Abstract Aim Mining is increasingly pressuring areas of critical importance for biodiversity conservation, such as the Brazilian Amazon. Biodiversity data are limited in the tropics, restricting the scope for risks to be appropriately estimated before mineral licensing decisions are made.

Unlocking the evolution of abdominal specializations in Luciuranus fireflies (Coleoptera, Lampyridae)

Zoologica Scripta, Volume 51, Issue 6, Page 708-723, November 2022., 2022
Abstract Understanding the evolution of genitalic traits and their co‐evolution between sexes is at the core of Evolutionary Biology. Cross‐species reproductive trait co‐variation can be the outcome of hybrid avoidance and/or sexual selection. Although the outcome of these two phenomena will look similar, they yield distinct patterns of species co ...

Agroecological farming, flowering phenology and the pollinator–herbivore–parasitoid nexus regulate non‐crop plant reproduction

Journal of Applied Ecology, Volume 59, Issue 8, Page 2046-2058, August 2022., 2022
Agroecological management produced spatial and temporal gradients in crop and non‐crop floral resources that interacted to modify pollinator or seed herbivore–parasitoid interactions and Cyanus segetum and Centaurea jacea seed set. The degree of phenological overlap between C. segetum and C.

Top‐down cascading effects of seed‐feeding beetles and their parasitoids on plants and leaf herbivores

Functional Ecology, Volume 36, Issue 6, Page 1500-1512, June 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract When feeding on a plant, herbivorous insects alter the quality of the plant as a food source. This affects other organisms interacting with the same plant. These so‐called ‘plant‐mediated interactions’ can be altered by parasitoids that attack the herbivores.
