Parasitoid wasps from three Jamaican localities: A pilot study [PDF]

open access: yesJournal of Hymenoptera Research, 2014
Parasitoid wasps are an extremely speciose, ecologically and economically crucial group of insects. Despite this, they have received disproportionally little attention from scientists, in particular in certain areas of the world.

Microbial Symbionts of Parasitoids

open access: yesAnnual Review of Entomology, 2020
Parasitoids depend on other insects for the development of their offspring. Their eggs are laid in or on a host insect that is consumed during juvenile development. Parasitoids harbor a diversity of microbial symbionts including viruses, bacteria, and fungi.

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.

Indirect and direct interactions between grain aphid and parasitoid in the presence of symbiont Regiella insecticola

open access: yesCABI Agriculture and Bioscience, 2023
Background Aphids often harbor bacterial symbionts that confer resistance to biotic and abiotic stress. Previous studies have primarily examined the direct effects of symbiont infection on parasitoid success but less on aphid population dynamics under ...

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 ...

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]

open access: yes, 2014
Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

The mechanism of the emergence of Cotesia kariyai (Hymenoptera: Braconidae) larvae from the host

open access: yesEuropean Journal of Entomology, 2006
At maturity, the endoparasitoid larvae of several subfamilies of the Braconidae have to emerge from inside of the host to pupate. Although the hosts hormonal milieu and the timing of larval parasitoid emergence have been studied, no report has yet ...

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.

Encapsulation and Hemocyte Numbers in Crocidolomia pavonana and Spodoptera litura Fabricius (Lepidoptera) Attacked by Parasitoid Eriborus argenteopilosus Cameron (Hymenoptera)

open access: yesHayati Journal of Biosciences, 2009
Eriborus argenteopilosus is the most important parasitoid attacking cabbage pest Crocidolomia pavonana in Indonesia. Previous studies proved that parasitoid encapsulation was found to be an important factor limiting the effectiveness of the parasitoid in
