Linda’s comments:  Makes you wonder if these new mosquitos are mutating, as they become resistant to chemicals??

Excerpt:

Most studies of malaria vectors, such as Anopheles gambiae, have focused on mosquitoes that rest indoors, since they are more likely to have contact with humans and transmit the malaria parasite. Larval stage and outdoor-resting mosquitoes are not as well-studied because they are more difficult to find and collect.
