Effects of lithium chloride on queen egg‐laying performance and worker honey bee behavior

Pest Management Science, Volume 82, Issue 1, Page 965-971, January 2026.
Chronic oral lithium chloride (LiCl) exposure effectively increases Varroa mite mortality without impairing queen egg laying or brood care behaviors, while significantly reducing worker bee aggression, suggesting its potential for safe Varroa management and mitigating colony aggression.

Laboratory and field evaluation of entomopathogenic fungi for the control of amitraz-resistant and susceptible strains of Rhipicephalus decoloratus

, 2016
Rhipicephalus decoloratus causes serious economic losses in cattle industry every year in East Africa. Biological control using entomopathogenic fungi is seen as a promising alternative to chemical acaricides being used for their control.

Levels, Determinants and Effects of Polychlorinated Biphenyls and Organochlorine Pesticides in Fish in Lake Victoria, Kenya

Aquaculture Research, Volume 2026, Issue 1, 2026.
Polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) are persistent organic pollutants (POPs) that are highly toxic even at low concentrations and bioaccumulate through aquatic food webs. This study quantified PCBs and OCPs concentrations using GC–MS analysis in 36 pooled samples from 154 Nile tilapia (Oreochromis niloticus) and ...

Report of eight children with amitraz intoxication

, 2003
Many pesticides are formulated in organic solvents. An example is amitraz, one of the formamidine groups of pesticidal chemicals. It is commonly used for the treatment of generalized demodicosis in dogs and for the control of ticks and mites in cattle ...

Voltammetric analysis of pesticides and their degradation: A case study of Amitraz and its degradants [PDF]

, 2006
Amitraz is a formamide acaricide used predominantly in the control of ectoparasites in livestock and honeybees. Amitraz hydrolysis is rapid and occurs under acidic conditions, exposure to sunlight and biodegradation by microorganisms. The main hydrolysis

Efeito da utilização de acaricidas em citros, sobre a população de Brevipalpus phoenicis (Geijskes, 1939) e ácaros predadores (Phytoseiidae) Effect of acaricide utilization in citrus on the population of Brevipalpus phoenicis (Geijskes, 1939) and predatory mites (Phytoseiidae)

Scientia Agricola, 1995
Foi conduzido experimento com o objetivo de estudar o efeito de alguns acaricidas sobre Brevipalpus phoenicis (Geijskes,1939) (AcarirTenuipalpidae) e ácaros predadores (Phytoseiidae), em citros.

Efeitos do amitraz sobre a pressão arterial e a temperatura retal de ratos [PDF]

, 1995
O presente trabalho estuda os efeitos da administração única de amitraz (100 mg/kg) sobre a pressão sangüínea arterial e a temperatura corporal de ratos Wistar. A administração de amitraz diminuiu a pressão sangüínea arterial e também produziu hipotermia.

Mutation in the RmβAOR gene is associated with amitraz resistance in the cattle tick Rhipicephalus microplus

, 2013
We aimed to describe the evolution of resistance to amitraz in Rhipicephalus microplus in the field and to test the association between amitraz resistance and the frequency of a mutation in the β-adrenergic octopamine receptor gene (RmβAOR).

Developmental exposure to amitraz impairs reproductive development and metabolic homeostasis in honey bee (

Ecotoxicology and Environmental Safety
Chemicals used within managed pollinator systems can become developmental stressors for non-target organisms, yet their effects on reproductively specialized individuals remain insufficiently understood. Here, we examined the developmental ecotoxicity of
