The interaction between Onthophagus binodis and cattle dung pH: Impacts on reproduction and offspring phenology

Physiological Entomology, Volume 49, Issue 3, Page 177-188, September 2024.
The presence of dung beetles made cattle dung more alkaline after 96 hours. Dung beetles were able to reproduce in cattle dung with a pH of 5.0, though in fewer numbers compared to other pH treatments. There were no negative impacts on emerging beetle physiology, though dung beetles emerging from pH 6.0 were larger compared to other pH treatments ...

Evidence of drastic loss of dung beetle diversity after 25 years in an introduced Brazilian pasture

Austral Ecology, Volume 49, Issue 4, April 2024.
Tunneller dung beetles markedly decreased its diversity throughout time. Medium‐ and larger‐bodied species were the most sensitive species. Abstract In tropical forest ecosystems, pastures are considered a limiting environment for dung beetles, with long‐term negative effects on the diversity of this group.

Comportamento da Haematobia irritans em fazendas com diferentes manejos de bovinos Behaviour Haematobia irritans in herd cattle farms under different management

Ciência Rural, 1997
A dinâmica parasitária da Haematobia irritans foi estudada em três fazendas com diferentes tipos de manejo de bovinos mestiços na região de São Carlos, SP, as quais não utilizavam nenhum tratamento específico à mosca. O experimento consistuiu na contagem

Developmental stress by diflubenzuron in Haematobia irritans (L.) (Diptera: Muscidae) [PDF]

Neotropical Entomology, 2004
This study aimed to assess the effect of sub-lethal concentrations of the insect growth regulator (IGR), diflubenzuron, on the body size of the horn fly Haematobia irritans (L.) and on its developmental stability, by fluctuating asymmetry (FA) analysis.

Identifying Risk Factors for Stephanofilaria‐Caused Ulcerative Dermal Lesions, in Black and White Rhinoceros’ Meta‐Population in Kenya

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Ulcerative skin lesions caused by Stephanofilaria dinniki are common in populations of the critically endangered eastern black rhinoceros (Diceros bicornis michaeli). Although considered benign, they have been associated with loss of body condition and mortality in rhinoceros.

Insecticide susceptibility of horn flies, Haematobia irritans (Diptera: Muscidae), in the State of Mato Grosso do Sul, Brazil Suscetibilidade da mosca-dos-chifres, Haematobia irritans (Diptera: Muscidae), a inseticidas no Estado de Mato Grosso do Sul, Brasil

Revista Brasileira de Parasitologia Veterinária, 2007
Horn fly susceptibility to insecticides was evaluated in the state of Mato Grosso do Sul, Brazil, from October 2000 to September 2002. Insecticide bioassays (n=57) were conducted in 38 ranches from 14 municipalities throughout the state.

Esterase patterns in four Brazilian populations of Haematobia irritans.

Cytobios, 1998
Four population samples of Haematobia irritans (horn flies), collected from farms and subjected, or not, to insecticide control, were analysed as to esterase bands by polyacrylamide gel electrophoresis. Eight esterase bands were detected in this species, a low number when compared with flies of other genera. The reduced number of esterase variants of H.

Genotype characterization of Haematobia irritans from different Brazilian geographic regions based on randomly amplified polymorphic DNA (RAPD) analysis Caracterização genotípica de Haematobia irritans procedentes de diferentes regiões geográficas brasileiras baseada na análise do DNA polimórfico amplificado ao acaso (RAPD-PCR)

Pesquisa Veterinária Brasileira, 2007
Blood-sucking diptera are important parasites in bovine production systems, especially regarding confinement conditions. Haematobia irritans, the horn fly, is one of the most troublesome species within bovine production systems, due to the intense stress
