Females of species A lay on average 2000 eggs female while

Females of species (A) lay on average 2000 eggs / female, while females of species (B) lay on average 10 eggs / female. The strength of density-dependent larval survival, d, and all other parameters are the same for the two species. How would you expect the density of adult mosquitoes to change for each species in response to an equivalent decrease in egg survival?

a. .Adult densities of species A and B will not change.

b. The density of adults of A will decline more than B

c. The density of adults of B will decline more than A

d. The density of adults of B will decrease, while the density of adults of A will increase

Solution

a. Adult density of A and B will not change

There is an equal decrease in egg survival , also the density dependent larval survival rate is same. But with equal decrease, the overall density change will not occur.
