Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Sugar conditioning combined with nectar nonsugar compounds enhances honey bee pollen foraging in a nectarless diocious crop

Scientific Reports
Recently, it has been shown that sugar‑conditioned honey bees can be biased towards a nectarless dioecious crop as kiwifruit. The challenges for an efficient pollination service in this crop species are its nectarless flowers and its short blooming ...

Evolution of Reproductive Plasticity in a Seasonal Tropical Environment

Ecology Letters, Volume 29, Issue 5, May 2026.
We reveal widespread occurrence of seasonal reproductive plasticity, including reproductive diapause, in Nymphalid butterflies in a seasonal rainforest in the Amazon. This highlights that, not only in temperate but also tropical habitats, seasonality is an important driver of plastic life history strategies. ABSTRACT Seasonality can drive the evolution

Desarrollo de un protocolo para producir quitosano a partir de la exuvia larval de Tenebrio molitor

Tecnología en Marcha
Muchos de los polímeros que son utilizados actualmente en la industria, investigación y otras áreas no son fácilmente biodegradables. Estos polímeros la mayoría de las veces suelen ser derivados del petróleo, lo que implica un gran impacto ambiental en ...

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

The ecology of attraction: Fruit traits and frugivore diversity in neotropical Piper

Functional Ecology, Volume 40, Issue 3, Page 611-623, March 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Fruit traits can benefit plant reproduction by enhancing seed dispersal by mutualistic frugivores (e.g. seed dispersal syndromes), but identifying the role of specific fruit traits in mediating frugivory is challenging because these traits can serve multiple functions ...

Insectos de Colombia

, 2021
Uno de los mayores retos del siglo XXI es el estudio de la diversidad biológica del planeta. Si hay un grupo de seres vivos para el cual este desafío es más dramático, es el de los insectos, artrópodos con casi 400 millones de años de historia y entre 5 y 10 millones de especies vivientes, la mayoría de estas sin descubrir ni describir.

Plant functional diversity does not dilute virus infection, but community virus prevalence positively correlates with net C3 grass production

Journal of Ecology, Volume 114, Issue 2, February 2026.
This study examines if plant functional diversity dilutes plant virus prevalence in grass hosts and evaluates how virus prevalence influences net community and host production. Functional diversity did not mitigate or amplify virus prevalence. While we found that species relationships between virus prevalence and production varied, overall, virus ...
