The first report of two parasitoids braconids wasps on sugar beet moth, Scrobipalpa ocellatella Boyd. (Lep.: Gelechidae) from Khorasan-e-Razavi province [PDF]

open access: yesMajallah-i Chughundar-i Qand, 2013
The sugar beet moth, Scrobipalpa ocellatella Boyd. (Lep.: Gelechidae( is the specific pest of beet. The aim of the present study was to identify the parasitoids of the moth.

Aphidiinae (Hymenoptera, Braconidae) aphid parasitoids of Malta : review and key to species [PDF]

open access: yes, 2015
This paper brings an annotated list of the 16 aphid parasitoids detected up to 2015 in Malta. All the species were reared from identified aphid-plant associations. An illustrated key to the identification of the recorded species from Malta is provided.

Life-history traits in closely related secondary parasitoids sharing the same primary parasitoid host: evolutionary opportunities and constraints [PDF]

open access: yes, 2009
Thus far, few studies have compared life-history traits amongst secondary parasitoids attacking and developing in cocoons of their primary parasitoid hosts.

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

open access: yes, 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.

A checklist of the predators and parasitoids of the fall webworm Hyphantria cunea (Drury) (Lepidoptera, Erebidae) from around the world [PDF]

open access: yesZooKeys
A checklist of 488 fall webworm Hyphantria cunea (Drury) natural enemies was compiled based on documentation in previous research across its world distribution, including 289 predators and 199 parasitoids.

Plant-mediated effects in the Brassicaceae on the performance and behaviour of parasitoids [PDF]

open access: yes, 2009
Direct and indirect plant defences are well studied, particularly in the Brassicaceae. Glucosinolates (GS) are secondary plant compounds characteristic in this plant family. They play an important role in defence against herbivores and pathogens.

Plant species loss affects life-history traits of aphids and their parasitoids. [PDF]

open access: yesPLoS ONE, 2010
The consequences of plant species loss are rarely assessed in a multi-trophic context and especially effects on life-history traits of organisms at higher trophic levels have remained largely unstudied.

Infectious Behavior in a Parasitoid

open access: yesScience, 2003
Solitary parasitoid insects usually lay only one egg per host and reject already parasitized hosts, because only one offspring can successfully develop ([ 1 ][1]). Despite the constraints, superparasitism is commonly observed.

Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]

open access: yes, 2011
Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

Moderately decreasing fertilizer in fields does not reduce populations of cereal aphids but maximizes fitness of parasitoids

open access: yesScientific Reports, 2021
Examination of the tradeoff between the extent of decreasing nitrogen input and pest suppression is crucial for maintaining the balance between essential yield and an efficient, sustainable pest control strategy.
