P LEASE W RITE Y OUR N AME H ERE : Samantha Swanhart Q#1. Briefly (<30 words) explain two reasons why specificity of an exotic natural enemy is so important for its utilization in classical biological control? (4 points) 1. Will not negatively affect beneficial species or attack native fauna or flora. 2. Will not dilute its control action on non-target species, it only focuses on target pest. Q#2. Keeping in mind the goal of classical biological control, briefly explain why each of the following factors is important to consider in a classical biological control program. (6 points) a. origin of the pest: natural enemies will adapt to finding and using the pest as a host in it’s area of origin; this will allow researchers to collect background information to make a “best fit” decision for which natural enemies to use to control a pest. b. climate: natural enemies are most likely to adapt and thrive in climates similar to the origin of the pest (they must be able to survive during the season in order to be efficient). c. resident natural enemy guild in the area invaded by the pest: you don’t want to waste money by introducing more natural enemies to an area where it is already inundated with enemies. Q#3. List four ways to reduce the mortality of predators and parasitoids by pesticides? (8 points) 1. Application methods such as spot treatments and bait. 2. Timing and frequency of application by using economic thresholds.
