Please select the best answer from the choices provided

True or false

Answer 1

False.

Biological control can and has replaced chemical controls in many situations (e.g., vedalia beetle controlling cottony cushion scale, sterile insect technique eradicating screwworm, Bacillus thuringiensis used instead of synthetic insecticides). However, it often complements chemicals within integrated pest management because effectiveness can vary by pest, crop, environment and time.
