117. Which chemical would you most likely use for subsurface feeders, neon- icotinoids or pyrethroids?: Neo because they have less binding ability to soil particles and organic matter than the pyrethroids and will therefore move down in the soil profile to the root zone where grubs are feeding.
118. Most of the white grubs we have as pest of turf grasses are introduced species. Why are introduced pests generally more damaging than native in- sects?: Because introduced pest species do not have the complement of parasites and predators that keep the insect population in check in its native range.

toxic chemicals to bees.

122. Which systemic insecticide is considered to have the lowest toxicity to bees?: Acelepryn.
123. Explain the difference between curative and preventative turf grass insect control.: Curative control is making an application when turf grass insects reach a threshold population level. Preventative applications are generally made before the target insect is present but may be based on a history of infestation

153. True or false: The neonicatanoids are effective for controlling many scale insects as a soil drench or basal trunk application. Imidacloprid would always be a better choice than acetamiprid as it lasts longer in the plant and will give me a longer window of control.: False
