Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Are sleeping site ecology and season linked to intestinal helminth prevalence and diversity in two sympatric, nocturnal and arboreal primate hosts (Lepilemur edwardsi and Avahi occidentalis)?

open access: yesBMC Ecology, 2018
Background Various factors, such as climate, body size and sociality are often linked to parasitism. This constrains the identification of other determinants driving parasite infections. Here, we investigate for the first time intestinal parasites in two

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.

Prevalence of gastrointestinal parasitism of cattle in Banskhali upazilla, Chittagong, Bangladesh

open access: yesJournal of Advanced Veterinary and Animal Research, 2015
The objectives of this study were to investigate the prevalence of gastrointestinal parasitism (GP), and to determine the effects of age, sex, breed, body score and body weight in the occurrences of GP of cattle in Banskhali Upazilla, Chittagong ...

IgA1 levels in milk and serum samples from intestinal parasite-infected or normal puerperae

open access: yesMemorias do Instituto Oswaldo Cruz, 2008
In this study, IgA1 levels in the milk and serum of puerperae were compared and a correlation was established between the levels of this immunoglobulin and the occurrence of parasitism.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

Exploring the immunology of parasitism--from surface antigens to the hygiene hypothesis [PDF]

open access: yes, 2009
Helminth immunology is a field which has changed beyond recognition in the past 30 years, transformed not only by new technologies from cDNA cloning to flow cytometry, but also conceptually as our definition of host immune pathways has matured.

Stapled side‐to‐side anastomosis to treat a pelvic flexure stricture in a miniature horse

open access: yesEquine Veterinary Education, EarlyView.
Summary Fecaliths are a recognised cause of non‐strangulating colon obstruction in horses. Although they more commonly obstruct the small colon, they can also lodge in the pelvic flexure, requiring enterotomy for removal. Stricture at the enterotomy site is an uncommon but surgically significant complication.

Histopathological study of experimental and natural infections by Trypanosoma cruzi in Didelphis marsupialis

open access: yesMemorias do Instituto Oswaldo Cruz, 1996
Didelphis marsupialis, the most important sylvatic reservoir of Trypanosoma cruzi, can also maintain in their anal scent glands the multiplicative forms only described in the intestinal tract of triatomine bugs.
