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

open access: yesInsects, 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 ...

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

open access: yes, 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 ...

Host Searching by Egg Parasitoids: Exploitation of Host Chemical Cues [PDF]

open access: yes, 2010
Insect parasitoids are considered “keystone species” in many ecosystems in terms of biodiversity, ecological impact and economic importance (Vinson 1985, LaSalle and Gauld 1993, Hawkins et al. 1999).

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

open access: yesEntomoBrasilis, 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]

open access: yes, 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.

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

open access: yesCumhuriyet 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.

Interactions between Bacillus thuringiensis and entomophagous insects

open access: yesEgyptian 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 ...

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

open access: yesInsects, 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.

Differing success of defense strategies in two parasitoid wasps in protecting their pupae against a secondary hyperparasitoid [PDF]

open access: yes, 2011
During their larval development, endoparasitoids are known to dispose of host resources in several different ways. Some parasitoid wasps consume most or all tissues of the host, whereas others consume a small fraction of host resources and either ensure ...
