b a ckground: the protective effect of two isolates of an entomopathogenic fungus, metarhizium anisopliae (demi 002 and iran 437c) on the adult stage of varroa destructor was evaluated in comparison with fluvalinate strips in the field. m e t hods: a total of 12 honey bee colonies were provided from an apiculture farm. the selected hives were divided into 4 groups (3 hives per group). the first...

Until the late 1980s, specific viral infections of the honey bee were generally considered harmless in all countries. Then, with the worldwide introduction of the ectoparasite mite Varroa destructor, beekeepers encountered increasing difficulties in maintaining their colonies. Epidemiological surveys and laboratory experiments have demonstrated that the newly acquired virulence of several virus...

The mite Varroa destructor is currently the greatest threat to apiculture as it is causing a global decrease in honey bee colonies. However, it rarely causes serious damage to its native hosts, the eastern honey bees Apis cerana. To better understand the mechanism of resistance of A. cerana against the V. destructor mite, we profiled the metabolic changes that occur in the honey bee brain durin...

Anualmente, se pierde más del 33 % de las colmenas en el altiplano y norte México por varroa (Varroa destructor), debido al uso excesivo acaricidas sintéticos. Como resultado, poblaciones ácaros han desarrollado resistencia. El objetivo esta investigación fue evaluar la caída V. destructor, así como porcentaje infestación mediante aplicación moliendas botánicas ajo (Allium sativum), laurel (Lau...

El objetivo de la investigación fue evaluar el efecto productos naturales alternativos en control Varroa destructor abejas melíferas (Apis mellifera) un apiario ubicado Sayán, región Lima, Perú. Se trabajó con cinco tratamientos (ácido oxálico, timol, vaselina, tabaco y control) seis replicaciones por durante 16 días. seleccionaron las colmenas tasas mayores a 2% infestación varroa evaluaciones...

Costic acid has been isolated from the plant Dittrichia viscosa and its efficacy against Varroa destructor, a parasite of Apis mellifera, the European honey bee, has been studied. Costic acid exhibited potent in vivo acaricidal activity against the parasite. Initial experiments showed that the compound is not toxic for human umbilical vein endothelial cells (HUVEC) at concentrations of up to 23...

Understanding the diversity and consequences of viruses present in honey bees is critical for maintaining pollinator health and managing the spread of disease. The viral landscape of honey bees (Apis mellifera) has changed dramatically since the emergence of the parasitic mite Varroa destructor, which increased the spread of virulent variants of viruses such as deformed wing virus. Previous gen...
