1. Which probability distribution is used in the negative binomial model to describe the spatial distribution of hosts?

a: Normal distribution Explanation

Explanation

b: Binomial distribution Explanation

Explanation

c: Poisson distribution Explanation

Explanation

d: Negative binomial distribution Explanation

Explanation

2. The clumping factor (k) in the negative binomial model primarily describes the following:

a: The carrying capacity of the habitat Explanation

Explanation

b: The reproductive rate of parasitoids Explanation

Explanation

c: The spatial aggregation (dispersion pattern) of the host population Explanation

Explanation

d: The lifespan of the parasitoid Explanation

Explanation

3. Why are parasitoids considered effective biological control agents?

a: They eliminate all insect species in an ecosystem. Explanation

Explanation

b: They readily switch to alternative host species. Explanation

Explanation

c: They are usually highly host-specific and maintain pest populations at low densities. Explanation

Explanation

d: They increase the reproductive rate of pest insects. Explanation

Explanation

4. During the simulation, increasing the searching efficiency (a) of the parasitoid is most likely to:

a: Increase the probability that hosts escape parasitism. Explanation

Explanation

b: Reduce the number of hosts surviving to the next generation. Explanation

Explanation

c: Eliminate the parasitoid population immediately. Explanation

Explanation

d: Increase the host reproductive rate. Explanation
