Comparative study on the egg parasitoids of Erthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) in its native and invaded ranges [PDF]
NeoBiotaErthesina fullo (Thunberg, 1783) (Hemiptera, Pentatomidae) is an emerging invasive pest outside its native Asian range, yet little is known about its egg parasitoids. Egg parasitoid assemblages were surveyed from field-collected egg masses of E. fullo in

The Significance of Background Odour for an Egg Parasitoid to Detect Plants with Host Eggs [PDF]
Chemical Senses, 2005 Scots pine has been shown to produce a volatile bouquet that attracts egg parasitoids in response to oviposition of the herbivorous sawfly Diprion pini. Previous analyses of headspace volatiles of oviposition-induced pine twigs revealed only quantitative changes; in particular, the sesquiterpene (E)-beta-farnesene was emitted in significantly higher ...

Phenotypic plasticity and fitness in egg parasitoids [PDF]
Neotropical 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]
Cold 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]
Journal 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 ...

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

European 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.

Frontiers 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
Ecology 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
Insects, 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.
