Mating Status of an Herbivorous Stink Bug Female Affects the Emission of Oviposition-Induced Plant Volatiles Exploited by an Egg Parasitoid

Frontiers in Physiology, 2019
Insect parasitoids are under selection pressure to optimize their host location strategy in order to maximize fitness. In parasitoid species that develop on host eggs, one of these strategies consists in the exploitation of oviposition-induced plant ...

An Egg Parasitoid Efficiently Exploits Cues From a Coevolved Host But Not Those From a Novel Host

Frontiers in Physiology, 2019
Egg parasitoids have evolved adaptations to exploit host-associated cues, especially oviposition-induced plant volatiles and odors of gravid females, when foraging for hosts.

Impact of egg mass layers and scale thicknesses of the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae), on the parasitic performance of Trichogrammatoidea bactrae (Hymenoptera: Trichogrammatidae)

Egyptian Journal of Biological Pest Control, 2023
Background Fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is one of the new alien destructive pests of maize and other 350 economic crops.

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

Journal 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 ...

Antennal Structures Used in Communication by Egg Parasitoids [PDF]

, 2009
Egg parasitoids are considered the most effective biocontrol agents of crop pests among parasitic wasps, since they are able to remove the herbivore from the agroecosystem before larval eclosion. The use of arthropod eggs as hosts by parasitoids has evolved in the Hymenoptera at least in 14 families.

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.

Cold storage-mediated rearing of Trichogramma evanescens Westwood on eggs of Plodia interpunctella (Hübner) and Galleria mellonella L.

PLoS ONE, 2021
The egg parasitoid Trichogramma evanescens Westwood is considered as an efficient biological control agent for managing several lepidopteran pests and it is widely distributed throughout the world. Mass rearing protocols of parasitoids that are currently

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.

Egg parasitoid attraction toward induced plant volatiles is disrupted by a non-host herbivore attacking above or belowground plant organs.

Frontiers in Plant Science, 2014
Plants respond to insect oviposition by emission of oviposition-induced plant volatiles (OIPVs) which can recruit egg parasitoids of the attacking herbivore.
