Effect of host egg age on preference, development and arrestment of Telenomus remus (Hymenoptera: Scelionidae)

open access: yesEuropean Journal of Entomology, 2012
Age of host eggs can be a limiting factor for egg parasitoids. It is expected that old eggs are less preferred by egg parasitoids, which can discriminate between eggs of different ages by using chemical cues.

Dominant Arctic Predator Is Free of Major Parasitoid at Northern Edge of Its Range

open access: yesFrontiers in Ecology and Evolution, 2019
Parasitoids can affect host population dynamics with community-level consequences. In the Arctic, a high diversity of parasitoids relative to potential hosts suggests that parasitoids may exert strong selection pressure on arthropods, but the extent to ...

Phenotypic plasticity in an egg parasitoid affects olfactory response to odors from the plant–host complex

open access: yesFrontiers in Ecology and Evolution, 2023
Female egg parasitoids must optimize their ability to find a suitable host for reproduction in a limited foraging time. Odorant cues associated with the plant–host complex play an essential role in guiding females toward the host.

An exotic parasitoid provides an invasional lifeline for native parasitoids

open access: yesEcology and Evolution, 2017
The introduction of an exotic species may alter food webs within the ecosystem and significantly affect the biodiversity of indigenous species at different trophic levels.

Biology of Glyphepomis dubia Campos & Souza, 2016 (Hemiptera: Pentatomidae) and the parasitoids Telenomus podisi Ashmead, 1893 and Trissolcus basalis (Wollaston, 1858) (Hymenoptera: Platygastridae) on rice

open access: yesBrazilian Journal of Biology, 2021
The life cycle of stink bug, Glyphepomis dubia and the development of two egg parasitoids (Telenomus podisi and Trissolcus basalis) were studied at the Federal University of Maranhão, at 26 ± 2oC, relative humidity (RH) of 60 ± 10% and 12h photophase ...

Oviposition experience promotes active reproductive behaviour in a synovigenic parasitoid [PDF]

open access: yesJournal of Hymenoptera Research, 2023
Parasitoids are important insects that are commonly released into the environment to reduce the population sizes of pest species. The lifetime reproductive success of parasitoids mainly depends on host availability and the availability of mature eggs ...

Only Females Oviposit: Chemical Discrimination of Adult Stink Bug Sex by the Egg Parasitoid Trissolcus japonicus

open access: yesFrontiers in Ecology and Evolution, 2021
Egg parasitoids foraging for suitable hosts scattered in the environment rely mainly on chemical cues. Elucidating the chemical ecology of natural enemies is important in the development of effective and successful strategies for conservation biological ...

Native egg parasitoids WCSB Spain

open access: yes, 2021
WCSB colonies were placed in a clone bank in 2017, 2018 and 2019 and in a pine forest in 2019. WCSB females laid egg masses along the weeks, which were available for native egg parasitoid.
