PSS final prep exam 2 questions &
answers 2024/2025
steps in classical biological control (6 steps) - ANSWERS1. choosing appropriate targets + generating
support
2. obtaining correct pest identification
3. surveys of the pest's natural enemies in the invaded area
4. identifying the pest's native range
5. collecting natural enemies in targeted locations
6. judging the potential of candidate natural enemies to suppress the pest
assessing safety and impact of candidates (4 steps) - ANSWERS1. creating colonies of natural enemies in
quarantine
2. estimating each natural enemy's host range
3. assessing impacts on the pest and non-target species
4. assessing the program's completeness and economic values
obtaining proper identification - ANSWERSconsult a systematist - herbarium, natural history museums,
science experts
molecular traits
mtDNA sequences - insects
chloroplast DNA for plants
desirable attributes for classical biological control agents - ANSWERSecological match with host habitat
temporal synchronization
high dispersal ability
host specificity
compatibility with host physiology
, simple food requirements
free from hyperparasitism
assessing safety and impact of candidates - ANSWERS1. petition for release
2. assessing impacts on the pest and non-target species (pre and post release)
3. assessing the program's completeness and economic values
new-association projects - ANSWERSnative pests may be controlled using relatives of pests from other
biogeographic regions (closely related, with same genus)
If the origin is unknown, a closely related species may be used to control the pest
constraints around new-association interactions - ANSWERSparasitoid may physiologically be unable to
overcome host defenses (ex. encapsulation)
host may be unattractive to natural enemy
natural enemy may show lower attack rates
CBC and new association projects do not appear to differ in terms of success
problems of new-association projects - ANSWERSnative weeds support other species (intros may
displace other natural enemies)
weeds may be valued as native plants in parks and nature reserves
natural enemies identified through new-associations projects have broader host ranges
successful case histories of CBC - ANSWERScheck class notes
augmentation - ANSWERSthe intentional release of natural enemies; either native or non-native, which
are naturally too low to manage the pest population
inundative releases - ANSWERSnatural enemies are released in the field to directly kill pests (not
expected to produce many offspring)
