Floral Cues And Foraging Preferences In Various Species Of Wild Bumblebees, Olivia A. Dahl
Floral Cues And Foraging Preferences In Various Species Of Wild Bumblebees, Olivia A. Dahl
The International Journal of Ecopsychology (IJE)
There are costs and benefits for plants and their pollinators. Bumblebees play a crucial role in the dynamic plant-pollinator system. Flowers co-evolved with insects, birds, and mammals toward mechanisms that benefited, described from a human perspective, both host and forager. Characteristics such color, olfactory cues, and temperature attract pollinators, with bumblebees showing preferences for blue and yellow flowers, as well as flowers that are warmer. This study aims to answer three questions: 1) How does floral temperature at different times of day predict visit length in bumblebees? 2) Does bumblebee size affect visit length? 3) Is there an interaction between …
Foraging Behavior Of Honeybees Exposed To Mosquito Insecticides, Samantha Marie Diel
Foraging Behavior Of Honeybees Exposed To Mosquito Insecticides, Samantha Marie Diel
Cal Poly Humboldt theses and projects
The main aim of this study was to quantify the effects of mosquito insecticides on honey bee (Apis mellifera), foraging behavior, explicitly assessing the impacts of adult mosquito control practices on honey bee health. The extent to which honey bees are exposed to pyrethrum, pyrethrins, permethrin, and pyrethroids is unknown, as are their effects on honey bee health and vitality. This study sought to answer this question by exposing honey bees to D-Phenothrin with the addition of Piperonyl butoxide (PBO), one of many synthetic pyrethroids widely used against adult mosquitoes to control mosquito-borne diseases. Honey bees were exposed to …
