Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

Ecological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

Cellular immune response of Amblyomma sculptum and Amblyomma americanum to entomopathogenic fungi: Implications for biological tick control

Medical and Veterinary Entomology, EarlyView.
Amblyomma sculptum showed a plasmatocyte‐dominant haemocyte profile. Beauveria bassiana increased plasmatocytes and reduced granulocytes, whereas Metarhizium robertsii did not cause significant changes. Amblyomma americanum showed a granulocyte‐dominant haemocyte profile. Beauveria bassiana reduced total haemocytes and granulocytes. B.

Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...

Survey of Smallholder Dairy Cattle Farming System and Antibiotic Residues in Raw Cow's Milk in Bagamoyo District, Tanzania

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Smallholder dairy farmers in Tanzania face livestock disease challenges that drive imprudent antimicrobial use and fuel antimicrobial resistance (AMR). In Bagamoyo, poor husbandry and limited disease control result in high prevalence of vector‐borne infections, commonly treated with oxytetracycline (OTC).

[A new generation of acaricide--attractant acaricidal granules].

Meditsinskaia parazitologiia i parazitarnye bolezni, 1999
The paper gives a brief account of the earlier results of papers with the development of attractive acaricidal granules (AAGs) and the results of their field tests in Tyumen Province and Krasnoyarsk Territory. AAGs in combination with sumithion yielded the best results than those with permethrin: their efficacy was over 90% and their action lasted 1.5 ...
