Laboratory bioassays were conducted to determine the contact honey bee toxicity of commercial and candidate neonicotinoid insecticides. The nitro-substituted compounds were the most toxic to the honey bee in our laboratory studies with LD50 values of

SUMMARYHoney bees (Apis mellifera) and bumble bees (Bombus impatiens) were compared for three aspects of pollinating behaviour on field-grown cucumber (Cucumis sativus) and watermelon (Citrullus lanatus). We measured: (1), diurnal foraging activity p

The number of honey bees (Apis mellifera L.) continues to decline due to parasitic mite pests and other factors. Honey bees and bumble bees (Bombus impatiens Cresson) were therefore compared for their effects on the seed set of watermelon [Citrullus

As a means to assess pollinator efficiency, the number of pollen grains deposited by honey bees (Apis mellifera L.) and bumble bees (Bombus impatiens Cresson) after single visits to pistillate watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] f
