Do primary and secondary host plants affect aphid- parasitoid interactions in fruit orchards?

Bulletin of Entomological Research, 2022
AbstractThe aim of this study was to investigate how the primary (PHP) and secondary host plants (SHP) in the fruit orchards affect the interactions of aphids and their parasitoids in northwest Turkey during spring and summer 2020 and 2021. In total, 67 tritrophic aphid–parasitoid-host plant interactions, including new association records for Europe ...

Primary Sex-Ratio and Differential Progeny Survivorship in Solitary Haplo-Diploid Parasitoids

Ecological Entomology, 1986
ABSTRACT. A method of partitioning emergence sex‐ratio to give estimates of primary sex‐ratio and male and female offspring survival from oviposition to emergence in solitary haplo‐diploid parasitoids is presented.

Effects of floral resources on the efficacy of a primary parasitoid and a facultative hyperparasitoid

Journal of Applied Entomology, 2019
AbstractResources added to agroecosystems to enhance biological control are potentially available to multiple members of the resident insect community—not only the biological control agents for which the resources are intended. Many studies have examined the effects of sugar feeding on the efficacy of biological control agents.

The hyperparasitoid Marietta picta mediates the coexistence of primary parasitoids of goji berry psyllid

Entomologia Generalis, 2020
Hyperparasitoids could disrupt the biological control system established by primary parasitoids. In Ningxia, China, accidentally introduced Marietta picta Andre was found since 2016 to hyperparasitize the primary parasitoid Tamarixia lyciumi Yang, a native biocontrol agent against the goji berry psyllid Paratrioza sinica Yang et Li.

The influence of insecticide residues on primary parasitoid and hyperparasitoid foraging behaviour in the laboratory

Entomologia Experimentalis et Applicata, 1996
AbstractThe behaviour of Aphidius rhopalosiphi DeStefani‐Perez (Hymenoptera: Braconidae) was recorded in laboratory bioassays in the presence and absence of both residues of honeydew from the English grain aphid, Sitobion avenae (F.) and the pyrethroid insecticide, deltamethrin.

Assessing trophic interactions in a guild of primary parasitoids and facultative hyperparasitoids: stable isotope analysis

Oecologia, 2006
Facultative hyperparasitism is likely to be the most common form of intraguild predation among parasitoids. However, difficulties associated with studying facultative hyperparasitoids in the field have hampered a thorough understanding of their trophic ecology.

Towards a comprehensive view of the primary structure of venom proteins from the parasitoid wasp Pimpla hypochondriaca

Insect Biochemistry and Molecular Biology, 2004
Venom from the parasitoid wasp Pimpla hypochondriaca has potent in vivo activity against insect haemocytes and disrupts host immune responses. Using hybridisation techniques, and more recently random sequence analysis, we had previously identified cDNAs encoding 10 venom proteins from this wasp and deduced their primary structures. We have now extended

The Ectoparasitic Pupal Parasitoid, Pachycrepoideus vindemmiae (Hymenoptera: Pteromalidae), Attacks Other Primary Tephritid Fruit Fly Parasitoids: Host Expansion and Potential Non-Target Impact

Biological Control, 2004
Abstract Pachycrepoideus vindemmiae Rondani is an ectoparasitic idiobiont parasitoid attacking puparia of many cyclorrhaphous Diptera. This study investigated its potential impact as a facultative hyperparasitoid of four other primary tephritid fruit fly parasitoids in Hawaii, Fopius arisanus (Sonan), Diachasmimorpha longicaudata (Ashmead ...

Development of a hyperparasitoid wasp in different stages of its primary parasitoid and secondary herbivore hosts

Journal of Insect Physiology, 2012
Parasitoid wasps are model organisms for exploring constraints on life history and development strategies in arthropods. Koinobiont parasitoids attack hosts that may vary considerably in size at parasitation. Thus far, studies exploring koinobiont development in hosts of different size have been exclusively done with primary parasitoids attacking ...

Body Odors of Parasitized Caterpillars Give Away the Presence of Parasitoid Larvae to Their Primary Hyperparasitoid Enemies

Journal of Chemical Ecology, 2014
Foraging success of parasitoids depends on the utilization of reliable information on the presence of their often, inconspicuous hosts. These parasitic wasps use herbivore-induced plant volatiles (HIPVs) that provide reliable cues on host presence. However, host searching of hyperparasitoids, a group of parasitoids that parasitize the larvae and pupae ...
