Potential of the Predatory Mites Gamasellodes lavafesii (Mesostigmata: Ascidae) and Cosmolaelaps mediocuspis (Mesostigmata: Laelapidae) on Different Soil Pests/Parasites and Alternative Prey for Large‐Scale Rearing

Journal of Applied Entomology, Volume 150, Issue 5, Page 562-572, June 2026.
ABSTRACT Many species of Mesostigmata soil mites have potential as biological control agents of pests/parasites. This study evaluated the predation potential of two of these species, Gamasellodes lavafesii (Ascidae) and Cosmolaelaps mediocuspis (Laelapidae).

Haemonchus contortus-Sheep relationship: A review.

Revista Científica, 2007
Haemonchosis, caused by the abomasal nematode Haemonchus contortus, is among the most relevant parasitic diseases of small ruminants all over the world. The infections are responsible for anemic and bad digestion/absorption syndromes causing the death of severely infected animals in acute cases and the reduction of production scores in the chronic ...

FEC Check: Development of a decision support tool to aid interpretation of gastrointestinal nematode faecal egg counts in sheep

Veterinary Record, Volume 198, Issue 9, Page e373-e384, 2/9 May 2026.
Abstract Background Gastrointestinal nematode infections are ubiquitous in grazing livestock worldwide impacting animal health and production. Faecal egg count (FEC) is an accessible diagnostic test that can guide the need for treatment. However, interpretation of FECs can be challenging.
