Sensory Mechanisms

AbstractHoney bee parasitic mites (Tropilaelaps mercedesae and Varroa destructor) detect temperature, humidity, and odor but the underlying sensory mechanisms are poorly understood. To uncover how T. mercedesae responds to environmental stimuli inside a hive, we identified the sensilla-rich sensory organ on the foreleg tarsus. The organ contained four types of sensilla, which may respond to different stimuli based on their morphology. We found the forelegs were enriched with mRNAs encoding sensory proteins such as ionotropic receptors (IRs) and gustatory receptors (GRs), as well as proteins involved in ciliary transport. We also found that T. mercedesae and Drosophila melanogaster IR25a and IR93a are functionally equivalent. These results demonstrate that the structures and physiological functions of ancient IRs have been conserved during arthropod evolution. Our study provides insight into the sensory mechanisms of honey bee parasitic mites, as well as potential targets for methods to control the most serious honey bee pest.

The basic complexes of behaviour reactions, directed on a fight against the parasitic mites of bees brood at the genusApisare shown, their comparative efficiency under various conditions and evolutional perspective. Possibility of ethological adaptation of honey bee toV. destructorparasiting, direction of selection by this sign and influencing of human on parasitic-host system was discussed. An approach to the selection of bees with the purpose of resistanse to varroosis promoution is proposed.

AbstractWestern honey bees, Apis mellifera L. (Hymenoptera: Apidae), occur in nearly every region inhabited by man because they provide valuable honey, wax, and pollination services. Many commercial honey bee operations are plagued by economically important parasites; however, beekeepers on the island of Newfoundland, Canada, are in a unique position because of the province of Newfoundland and Labrador’s strict import regulations and geographic isolation. We surveyed about 25% of the island’s approximately 100 managed honey bee colonies. The parasitic mites Varroa destructor Anderson and Trueman (Acari: Varroidae) and Acarapis woodi (Rennie) (Acari: Tarsonemidae) were not detected, whereas Nosema spp. microsporidia were detected in two of four beekeeping operations and in 11 of 23 (48%) colonies (intensity = 482 609 ± 1199 489 (mean ± SD); median intensity = 0). Because V. destructor and A. woodi are important pests that typically require chemical treatments, beekeepers on the island of Newfoundland may be uniquely positioned to market organic honey bee products from colonies that could also be a source of mite-naïve bees for research.

Guazuma Ulmifolia

Se evaluó la eficacia del humo de los frutos secos de Guazuma ulmifolia y los vapores de timol en el control del ácaro Varroa destructor infestando colonias de abejas africanizadas (Apis mellifera) de Yucatán. Se utilizaron tres tratamientos: Grupo 1 (G1), las colonias de abejas recibieron 5 a 8 bocanadas de humo de los frutos secos de G. ulmifolia dos veces por semana, durante un período de tres semanas; Grupo 2 (G2), las colonias recibieron 4-8 g de cristales de timol con tres aplicaciones cada siete días, y Grupo 3 (G3 o grupo control) las colonias no recibieron ningún tratamiento durante las tres semanas del experimento. Se colectaron 200 a 300 abejas adultas de cada colonia previo a la aplicación de los tratamientos (día 0) y a los 7, 14 y 21 días después de las aplicaciones, con la finalidad de determinar los niveles de infestación y eficacia de los tratamientos. Los resultados indican que los niveles de infestación de V. destructor en las abejas adultas disminuyeron al final del experimento (21 días) y fueron estadísticamente diferentes para los tres tratamientos, siendo menor para G2. La eficacia al final de los tratamientos fue de 41 y 69 %, para G1 y G2, respectivamente. Estos resultados corroboran que la aplicación de cristales de timol es una alternativa para el control del ácaro V. destructor en Yucatán, y que la aplicación del humo de los frutos secos de G. ulmifolia reduce los niveles de infestación de este parásito en comparación con las colonias que no recibieron ningún tipo de tratamiento (G3).
