The Ascomycete Brachiola Gambiae Parasitises the Mosquito Anopheles Gambiae

The ascomycete Brachiola gambiae parasitises the mosquito Anopheles gambiae. Adult female mosquitoes must take blood meals for their eggs to develop, and it is while they take blood that they transmit malarial parasites to humans. Male mosquitoes drink flower nectar. If humans are to safely and effectively use Brachiola gambiae as a biological control to reduce human deaths from malaria, then which of the following statements should be correct?

A) The ascomycete should not be harmful to other insects and must be harmful to male mosquitoes, but not to female mosquitoes.
B) The ascomycete should kill the mosquitoes before the malarial parasite they carry reaches maturity and should not be harmful to other insects.
C) The ascomycete should not be harmful to other insects and should infect mosquito larvae, rather than mosquito adults.
D) The ascomycete should infect mosquito larvae, rather than mosquito adults, and the subsequent decline in anopheline mosquitoes should not significantly disrupt human food resources.
