Parasitoid load affects plant fitness in a tritrophic system [PDF]

, 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 ...

Developmental Temperature Affects Life-History Traits and Heat Tolerance in the Aphid Parasitoid Aphidius colemani

Insects, 2021
Developmental temperature plays important roles in the expression of insect traits through thermal developmental plasticity. We exposed the aphid parasitoid Aphidius colemani to different temperature regimes (10, 20, or 28 °C) throughout larval ...

Determination of Parasitoids and its Parasitoids Life of Diplolepis fructuum (Rübsaamen) (Hymenoptera: Cynipoidea) as Pest of Rosehip (Rosa canina) in Sivas

Cumhuriyet Science Journal, 2017
Thisstudy was made to determine parasitoids and their parasitoids life of D.fructuum which are gall-inducing on Rosa canina. In the results ofthe study, as parasitoids were recorded thirteen species belong to Chalcidoideasuperfamily.

Occurrence of Megaselia scalaris Loew (Diptera: Phoridae) in Mischocyttarus cassununga Von Ihering (Hymenoptera: Vespidae: Polistinae) nests

EntomoBrasilis, 2022
Social wasp nests create an environment rich in resources, such as food and shelter, which consequently attract predators, parasites, and parasitoids. Parasitoids attacks can be one of the main causes of mortality among social wasps in the early stages ...

Large-scale migration synchrony between parasitoids and their host [PDF]

, 2015
1. Parasitoids are a valuable group for conservation biological control. In their role as regulators of aphid pests, it is critical that their lifecycle is synchronised with their hosts in both space and time.

Characterization of Hymenopteran Parasitoids of Aphis fabae in An African Smallholder Bean Farming System Through Sequencing of COI ‘Mini-barcodes’

Insects, 2019
Parasitoids are among the most frequently reported natural enemies of insect pests, particularly aphids. The efficacy of parasitoids as biocontrol agents is influenced by biotic and abiotic factors.

Interactions between Bacillus thuringiensis and entomophagous insects

Egyptian Journal of Biological Pest Control, 2020
The interactions between insect pathogens, parasitoids, and predators have been proposed as “intraguild predation (IGP).” It occurs when two species share a host or prey (and therefore may compete) or when they engage in a trophic interaction with each ...

Do age and mating status affect olfactory response of the parasitoid, Microplitis croceipes (Hymenoptera: Braconidae) to host-related plant odors? [version 1; referees: 2 approved]

F1000Research, 2018
Background: Parasitic wasps (parasitoids) use volatile organic compounds released by herbivore-infested plants to locate their hosts. Response of parasitoids to plant odors may be plastic and dependent on their physiological state.
