Life history and mating systems select for male biased parasitism mediated through natural selection and ecological feedbacks [PDF]

open access: yes, 2010
Males are often the "sicker" sex with male biased parasitism found in a taxonomically diverse range of species. There is considerable interest in the processes that could underlie the evolution of sex-biased parasitism.

Estimating Parasitism of Colorado Potato Beetle Eggs, \u3ci\u3eLeptinotarsa Decemlineata\u3c/i\u3e (Coleoptera: Chrysomelidae), by \u3ci\u3eEdovum Puttleri\u3c/i\u3e (Hymenoptera: Eulophidae) [PDF]

open access: yes, 2017
A computer simulation was used to evaluate methods for estimating parasitism of Colorado potato beetle egg mass populations by Edovum puttleri. The algorithm incorporated the specific attack behavior of E. puttleri, and a development time for parasitized

Host and Habitat Use by Parasitoids (Hymenoptera: Pteromalidae) of House Fly and Stable Fly (Diptera: Muscidae) Pupae [PDF]

open access: yes, 2018
House fly and stable fly pupae were collected during the summer from a dairy farm in northern Illinois. Spalangia nigroaenea accounted for most of the parasitoids recovered from house flies. Spalangia nigra, S.

Parasites

open access: yesMicrobiology Spectrum, 2016
ABSTRACT Parasites are an important cause of human disease worldwide. The clinical severity and outcome of parasitic disease is often dependent on the immune status of the host. Specific parasitic diseases discussed in this chapter are amebiasis, giardiasis, cryptosporidiosis, cyclosporiasis, cystoisosporiasis, microsporidosis, granulomatous ...

Higher gregarine parasitism often in sibling species of host damselflies with smaller geographical distributions [PDF]

open access: yes, 2012
1. This study investigated inter-specific variation in parasitism by gregarines (Eugregarinorida: Actinocephalidae), among sibling species of damselflies (Odonata: Zygoptera), in relation to relative size of geographical ranges of host species.

Morphodynamics of the Actin-Rich Cytoskeleton in Entamoeba histolytica

open access: yesFrontiers in Cellular and Infection Microbiology, 2018
Entamoeba histolytica is the anaerobic protozoan parasite responsible for human amoebiasis, the third most deadly parasitic disease worldwide. This highly motile eukaryotic cell invades human tissues and constitutes an excellent experimental model of ...

An experimental test of host's life history traits modulation in response to cuckoo parasitism risk. [PDF]

open access: yesPLoS ONE, 2017
Hosts can counteract parasites through defences based on resistance and/or tolerance. The mechanistic basis of tolerance, which involve defensive mechanisms minimizing parasite damage after a successful parasitic attack, remains poorly explored in the ...

A game demonstrating aspects of bumblebee natural history [PDF]

open access: yes, 2004
The Bumblebee Game is an exciting outdoor game, which demonstrates aspects of bumblebee natural history including food chains, food webs and competition for food, predation by crab spiders, parasitism by Conopidae (Diptera) and brood parasitism by ...

Osteopontin in the host response to Leishmania amazonensis

open access: yesBMC Microbiology, 2019
Background Leishmania (L.) spp are intracellular eukaryotic parasites responsible for cutaneous or visceral leishmaniasis, replicating predominantly in macrophages (MF). In C57BL/6 mice virulence with L. amazonensis has been associated with inhibition of
