1. Which of the following is the primary goal of integrated pest
management (IPM) in forest pest control?
A. Eliminate all insect populations
B. Maximize chemical pesticide use
C. Maintain pest populations below economically or ecologically
damaging levels
D. Promote monoculture planting
IPM in forest pest control focuses on managing pest populations at levels
that prevent significant economic or ecological damage rather than
complete eradication, using a combination of biological, cultural, and
chemical controls.
, 2. When applying a systemic insecticide to control bark beetles in pine
forests, the most effective timing is:
A. Late summer, after beetle emergence
B. Early spring, before beetle flight and oviposition
C. Winter, during dormancy
D. Mid-autumn, after tree senescence
Systemic insecticides are most effective when applied before the target
pest becomes active, allowing the chemical to circulate within the tree
tissue and protect against feeding or oviposition.
3. Which factor most influences the susceptibility of a forest stand to
gypsy moth (Lymantria dispar) infestation?
A. Stand proximity to urban areas
B. Tree species composition and age
C. Soil pH levels
D. Annual precipitation totals
Gypsy moth larvae preferentially feed on certain tree species and age
classes; stands with a high proportion of preferred species like oaks are at
higher risk.
4. In forest pest surveys, pheromone traps are primarily used to:
A. Reduce pest populations directly
B. Monitor adult insect populations and detect early infestations
C. Apply insecticides more efficiently
D. Encourage pest dispersal
Pheromone traps attract specific insect species, allowing for population
monitoring and early detection, which is critical for timely management
interventions.
5. Which of the following is considered a cultural control strategy for
forest pest management?
, A. Aerial application of synthetic insecticides
B. Thinning dense stands to reduce host stress
C. Introduction of predatory beetles
D. Soil fumigation
Cultural controls alter the environment or host conditions to make them
less favorable for pests, such as thinning to reduce tree stress and
vulnerability.
6. What is the primary method by which bark beetles kill trees?
A. Root consumption
B. Gallery construction under the bark, disrupting phloem transport
C. Leaf defoliation
D. Injecting toxic secretions into foliage
Bark beetles bore into the cambium and phloem layers, interrupting
nutrient and water transport, which can rapidly kill the tree.
7. The use of a broad-spectrum insecticide in a forest ecosystem may
have which of the following consequences?
A. Targeted control of one species only
B. Non-target species mortality and disruption of ecological balance
C. Increased tree growth rates
D. Enhanced natural predator populations
Broad-spectrum insecticides affect many insects, including beneficial
predators and pollinators, potentially causing secondary pest outbreaks
and ecological disruption.
8. Which pathogen is commonly used as a biological control agent
against forest-defoliating insects?
A. Fusarium wilt
B. Bacillus thuringiensis (Bt)
