Parasitoid load affects plant fitness in a tritrophic system [PDF]

open access: yes, 2008
Plants attacked by herbivorous insects emit volatile compounds that attract predators or parasitoids of the herbivores. Plant fitness increases when these herbivorous insects are parasitized by solitary parasitoids, but whether gregarious koinobiont ...

Cascading bottom‐up effects of invasive alien plants on the parasitoid Aphidius colemani mediated by the aphid host Aphis fabae

open access: yesPest Management Science, EarlyView.
Differences in the suitability of invasive alien plants as hosts drove variations in cascading bottom‐up effects in aphid host and parasitoid performance, potentially influencing top‐down regulation. Abstract BACKGROUND Invasive alien plants (IAP) can threaten biodiversity by disrupting trophic interactions and, consequently, affect agroecosystems by ...

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

Response of parasitoid egg load to host dynamics and implications for egg load evolution [PDF]

open access: yesJournal of Evolutionary Biology, 2017
AbstractA theoretical debate about whether parasitoids should be time or egg limited now recognizes both as feasible, and interest has turned to determining the circumstances under which each might arise in the field, and their implications for parasitoid behaviour and evolution.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Trichogramma: a Promising Biocontrol Agent

open access: yesInternational Journal of Economic Plants, 2023
Parasitoids that are able to remove the herbivore from the agroecosystem before larval eclosion are known as egg parasitoids. Mostly they belong to the Hymenopteran order which includes 15 families. Adult of Trichogramma spp. is 0.2-1.00 mm in size with

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Functional variation in butterfly egg pore traits: The potential role of climate

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

First Report of Native Parasitoids of Fall Armyworm Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) in Mozambique

open access: yesInsects, 2020
The alien invasive insect pest Spodoptera frugiperda Smith (Lepidoptera: Noctuidae), commonly referred to as fall armyworm (FAW), is causing significant losses to maize production in Africa since its detection in 2016.
