Increased fluctuation in a butterfly metapopulation leads to diploid males and decline of a hyperparasitoid [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2018
Climate change can increase spatial synchrony of population dynamics, leading to large-scale fluctuation that destabilizes communities. High trophic level species such as parasitoids are disproportionally affected because they depend on unstable resources.

A preventive strategy for the control of aphids in sweet pepper using lacewings and micrococcinelid beetles

Insect Science, Volume 33, Issue 4, Page 1663-1674, August 2026.
Aphids pose a serious risk to horticultural crops. Current biocontrol strategies often fail due to the poor establishment of natural enemies when aphids are scarce. We evaluated the potential of two aphidophagous predators, Micromus variegatus and Scymnus interruptus, to be used as preventive biocontrol agents, released before aphid infestation.

High‐Throughput DNA Barcoding Reveals Multi‐Trophic Networks of Plants, Leafminers and Parasitoids in a Tropical Dry Forest

Molecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT Tropical dry forests host highly diverse insect communities and complex trophic interactions, yet these networks remain difficult to resolve using conventional molecular or rearing‐based approaches. Here, we integrate long‐read DNA barcoding, non‐target sequence co‐amplification, and host plant taxonomy to reconstruct tri‐trophic interactions ...

First record of Diaeretus leucopterus (Haliday) (Hymenoptera, Braconidae, Aphidiinae), the parasitoid of the aphid species, Eulachnus agilis (Kaltenbach) (Hemiptera, Aphididae) in North Africa

Egyptian Journal of Biological Pest Control, 2020
A survey of pine-associated aphids and their parasitoids was carried out in the arboretum of Pinus halepensis Miller in the Higher Agronomic Institute Chott Mariem (ISA CM, Tunisia) during 2010–2011 and 2018. The survey revealed the presence of the aphid

Ecosystem Services Against Illegal Immigration: The Natural Control of the Migratory Butterfly Painted Lady (Vanessa cardui) by Cotesia vestalis (Hymenoptera, Braconidae) on Organic Soybean in Ukraine

Entomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 922-932, August 2026.
In central Ukraine, the migratory butterfly Vanessa cardui emerged as a key pest of organic soybean during its outbreaks in 2019 and 2022. Despite early defoliation, crops recovered strongly due to high parasitism by Cotesia vestalis, reaching 100% in some fields.

Population dynamics and species composition of maize field parasitoids attacking aphids in northeastern China.

PLoS ONE, 2020
Maize, Zea mays L., is the most abundant field crop in China. Aphids are the most economically damaging pest on maize, particularly in the maize agri-ecosystems of Jilin Province, northeastern China.

Trophic complexity and the adaptive value of damage-induced plant volatiles.

PLoS Biology, 2012
Indirect plant defenses are those facilitating the action of carnivores in ridding plants of their herbivorous consumers, as opposed to directly poisoning or repelling them.
