Bees In bees, the lethal concentration ( LC 50 ) of bifenthrin is about 17 mg/L. [ 11 ] At sublethal concentrations, bifenthrin reduces the fecundity of bees, decreases the rate at which bee larvae develop into adults, and increases their immature periods.
Fipronil is toxic to bees and should not be applied to vegetation when bees are foraging. [28] Based on ecological effects, fipronil is highly toxic to upland game birds on an acute oral basis and very highly toxic on a subacute dietary basis, but is practically nontoxic to waterfowl on both acute and subacute bases.

Viburnum lesquereuxii leaf with insect damage; Dakota Sandstone (Cretaceous) of Ellsworth County, Kansas. Scale bar is 10 mm. Knowledge of herbivory in geological time comes from three sources: fossilized plants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilised animal feces; and the structure of herbivore mouthparts.
It also contaminates vehicles parked beneath trees, and can then be difficult to remove from glass and bodywork. Honeydew is also secreted by certain fungi, particularly ergot. [8] Honeydew is collected by certain species of birds, mosquitoes, [9] [10] wasps, stingless bees [11] and honey bees, which process it into a dark, strong honey ...

It is native to Wyoming, Colorado, and New Mexico in the United States. [1] This is a small, mat-forming, long-lived perennial herb with gray-green, hairy leaves and solitary flower heads.
Bees have been shown to be particularly sensitive to pyrethrin, with fatal doses as small as 0.02 micrograms. [1] Due to this sensitivity and pollinator decline , pyrethrins are recommended to be applied at night to avoid typical pollinating hours, and in liquid rather than dust form.
