Rapid Establishment of a Regular Distribution of Adult Tropical Drosophila Parasitoids in a Multi-Patch Environment by Patch Defence Behaviour. [PDF]

, 2011
Females of the larval parasitoid of Drosophila, Asobara citri, from sub-Saharan Africa, defend patches with hosts by fighting and chasing conspecific females upon encounter.

Characteristics of the meconia of European egg parasitoids of Halyomorpha halys [PDF]

Journal of Hymenoptera Research, 2020
Halyomorpha halys is a severe invasive Asian pest worldwide and classical biological control is foreseen as the most promising control method. Egg parasitoids appear to be the most important natural enemies of this pest, especially the Asian hymenopteran

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 ...

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.

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.

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.

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.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.
