Nota Técnica Ramírez, Marianyela Calderón, Rafael A. acido fórmico timol Varroa destructor abejas africanizadas cría sellada formic acid thymol Varroa destructor Africanized honeybees sealed brood cells The mortality of the Varroa destructor mite was evaluated in capped worker brood cells by using formic acid and thymol in Africanized honey bee colonies. The apiary was located in Atenas, Alajuela, Costa Rica, and was randomly arranged in three groups: A, B and C. Group A was treated with 150 g formic acid at 65%, while group B received two applications of 25 g thymol, and group C was used as a control group. Mortality of the Varroa’s different stages was evaluated in capped worker brood cells by checking the pupa and the bottom of the cell for mites. Eighty-six percent mite mortality occurred in capped brood cells in colonies treated with formic acid, while Varroa mortality was less than 10% in capped cells for control colonies and colonies treated with thymol. In conclusion, high mortality of Varroa mites was observed in capped brood cells after applying formic acid, while mortality was low in control colonies and colonies treated with thymol. The foregoing could imply a direct effect of formic acid over mites in capped brood cells. Se evaluó la mortalidad del ácaro Varroa destructor en cría sellada de obrera, al aplicar ácido fórmico y timol en colmenas de abejas africanizadas. El apiario se ubicó en Atenas, Alajuela - Costa Rica. Este se dividió en tres grupos seleccionados al azar (A, B y C). El grupo A fue tratado con 150 g de ácido fórmico al 65%; en el B se realizó dos aplicaciones de 25 g de timol;  el C se utilizó como testigo. La mortalidad de los diferentes estadios de varroa fue evaluada en cría sellada de obrera, revisando la pupa y el fondo de la celda. Se determinó una mortalidad de 86% en los diferentes estadios de varroa en cría sellada de obrera luego de aplicar ácido fórmico. Mientras que en colmenas tratadas con timol y el grupo testigo, la muerte de ácaros, en cría sellada, fue menor a un 10%.  Se concluye que, al aplicar ácido fórmico, se produce una alta mortalidad de los diferentes estadios del ácaro V. destructor en la cría sellada de obrera. Mientras tanto, en las colmenas tratadas con timol y el grupo testigo, la mortalidad de ácaros fue considerablemente menor, lo cual puede indicar un efecto directo del ácido fórmico sobre los ácaros presentes en la cría sellada de obrera.
