Effects of temperature and humidity on the presence and prevalence of a common fungal parasite on an invasive ladybird

open access: yesEcological Entomology, Volume 51, Issue 1, Page 86-97, February 2026.
We investigated how temperature and relative humidity influence the parasitic fungus Hesperomyces harmoniae on the invasive ladybird Harmonia axyridis under controlled laboratory conditions. Abiotic factors significantly affect parasitism: High relative humidity increased parasite prevalence, development rate, and load, while both low and high ...

Long-term changes in communities of native coccinellids: population fluctuations and the effect of competition from an invasive non-native species [PDF]

open access: yes, 2016
1. We assessed the changes in abundance and community composition of native species of coccinellids (Coleoptera: Coccinellidae) on deciduous trees that occurred between 1970s and 2010s, in the Czech Republic. 2.

Biological corridors are crucial habitat features that boost biodiversity in agroecological systems of Argentina

open access: yesEcological Solutions and Evidence, Volume 7, Issue 1, January/March 2026.
Our work shows for the first time in the region that biological corridors increase biodiversity and promote interactions between different components of the production system, using a methodology never before used in Argentina such as the Griffon index.

Meta‐analysis on effects of Bt‐maize on nontarget invertebrates – Data transportability across continents

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 1, Page 365-376, January 2026.
Maize varieties producing insecticidal proteins from Bacillus thuringiensis (Bt) have become an important component of integrated pest management worldwide. For regulatory approval of such plants, risks to the environment need to be assessed. To make such assessments less expensive and time‐consuming, conclusions drawn from data collected in one region

Antagonistic interactions between an invasive alien and a native coccinellid species may promote coexistence [PDF]

open access: yes, 2016
1. Despite the capacity of invasive alien species to alter ecosystems, the mechanisms underlying their impact remain only partly understood. Invasive alien predators, for example, can significantly disrupt recipient communities by consuming prey species ...

Synchronous seasonal plasticity in coloration, behaviour and visual gene expression in a wild butterfly population

open access: yesFunctional Ecology, Volume 40, Issue 1, Page 51-69, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Phenotypic plasticity allows many animals to quickly respond to seasonal changes in their environment. Seasonal changes to physiological systems, such as sensory systems, may explain other more obvious changes in behaviour, often working synergistically with changes in ...

First record of Hesperomyces virescens (Laboulbeniales, Ascomycota) on Harmonia axyridis (Coccinellidae, Coleoptera) in Poland

open access: yesActa Mycologica, 2016
Hesperomyces virescens Thaxt. is a fungal parasite of coccinellid beetles. One of its hosts is the invasive harlequin ladybird Harmonia axyridis (Pallas). We present the first records of this combination from Poland.

Evaluating Promotional Approaches for Citizen Science Biological Recording: Bumblebees as a Group Versus Harmonia axyridis as a Flagship for Ladybirds [PDF]

open access: yes, 2017
Over the past decade, the number of biological records submitted by members of the public have increased dramatically. However, this may result in reduced record quality, depending on how species are promoted in the media.
