Phenotypic plasticity and fitness in egg parasitoids [PDF]

open access: yesNeotropical Entomology, 2010
Several proxies can be used to estimate the fitness of egg parasitoids: size, longevity, fecundity, mating ability and vagility. All these proxies are positively correlated with the lifetime fitness gain of an individual. However, the phenotypic plasticity, which is the ability of a genotype to produce distinct phenotypes depending on environmental ...

Egg Collection for Nasonia (Parasitoid Wasp) [PDF]

open access: yesCold Spring Harbor Protocols, 2009
INTRODUCTIONNasonia is a complex of four closely related species of wasps with several features that make it an excellent system for a variety of genetic studies. These include a short generation time, ease of rearing, interfertile species, visible and molecular markers, and a sequenced genome.

Parasitoids of the invasive Nezara viridula (Linnaeus) in Bulgaria [PDF]

open access: yesJournal of Central European Agriculture, 2022
The southern green stink bug Nezara viridula (Linnaeus) is a polyphagous species that causes economic damages to many crops in Bulgaria. The aim of this study was to identify the parasitoid species that could suppress the populations of Nezara viridula ...

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.

Parasitoid Complex of Fall Armyworm, Spodoptera frugiperda, in Ghana and Benin

open access: yesInsects, 2020
The fall armyworm, Spodoptera frugiperda, a moth originating from the American continent, has recently invaded most African countries, where it is seriously threatening food security as a pest of cereals.

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 ...
