Parasitoid load affects plant fitness in a tritrophic system

, 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 ...

Influence of egg traits on parasitism by Trichogramma chilonis Ishii, 1941 and Telenomus remus Nixon, 1937 against Spodoptera frugiperda (J.E. Smith, 1797)

Frontiers in Insect Science
Trichogramma chilonis Ishii, 1941 and Telenomus remus Nixon, 1937 are the most common egg parasitoids of fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith, 1797) in maize growing areas.

Choosy egg parasitoids: Specificity of oviposition‐induced pine volatiles exploited by an egg parasitoid of pine sawflies

Entomologia Experimentalis et Applicata, 2005
AbstractGeneralist parasitoids are well‐known to be able to cope with the high genotypic and phenotypic plasticity of plant volatiles by learning odours during their host encounters. In contrast, specialised parasitoids often respond innately to host‐specific cues.

The transcriptomic basis of oviposition behaviour in the parasitoid wasp Nasonia vitripennis [PDF]

, 2013
Linking behavioural phenotypes to their underlying genotypes is crucial for uncovering the mechanisms that underpin behaviour and for understanding the origins and maintenance of genetic variation in behaviour.

Surveys in northern Utah for egg parasitoids of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) detect Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) [PDF]

Biodiversity Data Journal, 2020
The highly polyphagous and invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has become a significant insect pest in North America since its detection in 1996.

Life-history traits in closely related secondary parasitoids sharing the same primary parasitoid host: evolutionary opportunities and constraints

, 2009
Thus far, few studies have compared life-history traits amongst secondary parasitoids attacking and developing in cocoons of their primary parasitoid hosts.

The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps

, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Proactive assessment of a native North American egg parasitoid, Anastatus reduvii (Hymenoptera: Eupelmidae), as a potential biological control agent of Lycorma delicatula (Hemiptera: Fulgoridae), in California

Biological Control
The spotted lanternfly, Lycorma delicatula, native to parts of East Asia and the Indomalayan region, is a polyphagous herbivore poised to become a major global agricultural pest. Since its establishment in the US in 2014, L.

Loss, persistence and reversal of phenotypic traits

Biological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...
