Comparison of the Parasitization of Chelonus inanitus L. (Hymenoptera: Braconidae) in Two Spodoptera Pests and Evaluation of the Procedure for Its Production

open access: yesInsects, 2022
Chelonus inanitus (L.) is an egg-larval parasitoid of noctuids Spodoptera exigua (Hübner) and S. littoralis (Boisduval), whose mass rearing or real potential has not been targeted yet.

A Link Between Communities of Protective Endosymbionts and Parasitoids of the Pea Aphid Revealed in Unmanipulated Agricultural Systems

open access: yesFrontiers in Ecology and Evolution, 2021
In the last decade, the influence of microbial symbionts on ecological and physiological traits of their hosts has been increasingly recognized. However, most of these effects have been revealed under laboratory conditions, which oversimplifies the ...

Hymenopteran parasitoids reared from European gall midges (Diptera, Cecidomyiidae) [PDF]

open access: yesBiodiversity Data Journal
We report the results of investigations 2010 through 2023 of hymenopteran parasitoids associated with gall midges in Europe. A total of 242 collections of gall midges were made, from each of which one to several parasitoid species emerged, resulting in ...

Competitive interactions between parasitoids provide new insight into host suppression. [PDF]

open access: yesPLoS ONE, 2013
Understanding the dynamics of potential inter- and intraspecific competition in parasitoid communities is crucial in the screening of efficient parasitoid species and for utilization of the best parasitoid species combinations.

Aphid parasitism alters induced plant responses allowing a hyperparasitoid to locate its hidden parasitoid host. [PDF]

open access: yesNew Phytol
Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of

Temperature variability homogenized thermal responses in an ectotherm community along a European longitudinal gradient

open access: yesEcography, EarlyView.
Climate change, through rising temperatures, greater variability, and more frequent extremes, is reshaping insect phenology and thermal niches, with profound effects for pest outbreaks. Predicting these impacts requires a clear understanding of species and communities' responses across geographic gradients.

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

open access: yesGlobal Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

An Evaluation of the Effects of Delayed Parasitism on Daily and Lifetime Fecundity of Aphidius ervi Haliday

open access: yesInsects
The study of parasitoid reproductive behaviour is crucial to understanding how parasitoids influence host population dynamics, and the strategies used by parasitoids to maximize their reproductive success.

“Tremble, pests”: Insect natural enemy‐induced changes in pests before attack and their implications for biological control

open access: yesNew Plant Protection, EarlyView.
Abstract Insect natural enemies, encompassing predators and parasitoids, serve as vital regulators of pest populations and architects of ecosystem balance. Most studies on natural enemies have focused on understanding the mechanisms by which these insects eliminate pests after an attack.

Diversity of parasitoid wasps in conventional and organic guarana (Paullinia cupana var. sorbilis) cultivation areas in the Brazilian Amazon [PDF]

open access: yesActa Amazonica, 2019
We surveyed parasitoid wasps (Hymenoptera) in two guarana plantations in the central Brazilian Amazon (one conventionally, and one organically managed), as well as in adjacent forest and edge areas between crop and forest.
