Native Bee

Lowbush blueberry (Vaccinium angustifolium Ait., V. myrtilloides Michx.) growers often use colonies of the European honey bee (Apis mellifera L.) to supplement native bee populations for pollination. Native bee fauna is thought to be insufficient in number and too unpredictable, in terms of numbers, from year to year to be relied on for adequate crop pollination (Kevan and LaBerge 1978; Mackenzie and Winston 1984; Mohr and Kevan 1987; Kevan 1988; Eck 1988).

El uso indiscriminado de insecticidas sintéticos incrementa los riesgos de contaminación al ambiente, daños a la salud y reducción de poblaciones de organismos benéficos, además de selección de resistencia de las plagas a esos productos. Ante este escenario, se requieren alternativas eficientes y menos nocivas para el humano y los organismos no blanco. En esta investigación se evaluó la toxicidad aguda del insecticida-acaricida botánico BIODIe® (a base de extractos vegetales de higuerilla, chicalote y berberis) sobre dos polinizadores -abejas y abejorros- y sobre los depredadores Chrysoperla carnea y Orius insidiosus, se usaron tres metodologías de exposición: contacto directo, contacto residual y toxicidad oral.  El insecticida botánico fue ligeramente tóxico para los polinizadores y depredadores estudiados, y se clasificó en la categoría 1 de la organización internacional de control biológico (IOBC) debido a la baja mortalidad (<25%). Esto sugiere que este producto representa riesgos bajos para organismos no blanco en su implementación en el manejo integrado de plagas.

Orderly Arrangement

The key morphological feature that distinguishes corbiculate bees from other members of the Apidae family is the presence of the corbicula (pollen basket) on the tibial segment of hind legs. Here, we show that in the honeybee ( Apis mellifera ), the depletion of the gene Ultrabithorax ( Ubx ) by RNAi transforms the corbicula from a smooth, bristle-free concave structure to one covered with bristles. This is accompanied by a reduction of the pollen press, which is located on the basitarsus and used for packing the pollen pellet as well as a loss of the orderly arrangement of the rows of bristles that form the pollen comb. All these changes make the overall identity of workers’ T3 legs assume that of the queen. Furthermore, in a corbiculate bee of a different genus, Bombus impatiens , Ubx expression is also localized in T3 tibia and basitarsus. These observations suggest that the evolution of the pollen gathering apparatus in corbiculate bees may have a shared origin and could be traced to the acquisition of novel functions by Ubx , which in Apis were instrumental for subsequent castes and behavioural differentiation.

Social Bees

Agriculturally important commercially managed pollinators including honey bees (Apis mellifera L., 1758) and bumble bees (Bombus impatiens Cresson, 1863) rely on the surrounding landscape to fulfill their dietary needs. A previous study in Europe demonstrated that managed honey bee foragers and unmanaged native bumble bee foragers are associated with different land uses. However, it is unclear how response to land use compares between managed honey bees and a managed native bumble bee species in the United States, where honey bees are an imported species. Furthermore, to our knowledge, no such direct comparisons of bee responses to land use have been made at the colony level. To better understand how two different social bees respond to variation in land use, we monitored the weights of A. mellifera and B. impatiens colonies placed in 12 apiaries across a range of land use in Michigan, United States in 2017. Bombus impatiens colonies gained more weight and produced more drones when surrounded by diverse agricultural land (i.e., non-corn/soybean cropland such as tree fruits and grapes), while honey bee colonies gained more weight when surrounded by more grassland/pasture land. These findings add to our understanding of how different bee species respond to agricultural landscapes, highlighting the need for further species-specific land use studies to inform tailored land management.

The Relationship

The ability to accurately estimate bee mass through measurements of intertegular distance (ITD) is an important tool for field biologists. ITD is the distance between the bases of the 2 wing tegulae on the bee’s thorax. However, the relationship between ITD and bee mass can vary based on species and sampling region. A collection of 92 bees—representing 3 species—was examined to assess the accuracy of ITD in estimating dry mass for bees in northwest Ohio.  The focus was on 3 species: silky striped sweat bees (Agapostemon sericeus), honey bees (Apis mellifera), and common eastern bumble bees (Bombus impatiens).  Overall, there was a positive correlation between ITD and dry mass across all individuals sampled (R2 = 0.77), but within species the degree of correlation varied significantly. The results suggest that ITD accurately estimates dry mass in silky striped sweat bees (R2 = 0.93), but the correlation weakens in common eastern bumble bees (R2 = 0.54) and is non-existent in honey bees (R2 = 0.39). Field biologists interested in using ITD to estimate bee mass should take preliminary measurements when investigating bumble bees, and should avoid ITD estimates in honey bees.
