Summoning Moaquitoes Parasites sometimes alter their hosts behavior in a way that increase their chances of transmission to another host. Dr. Jacob Koella and his associates hypothesized that Plasmodium might benefit by making its human host more attractive to hungry mosquitoes when gametocytes are available in the hosts blood. Gametocytes taken up by the mosquito will mature into gametes and mate inside its gut. To test their hypothesis, the researchers recorded the response or mosquitoes to the odor or Plasmodium-infected children and uninfected children over the course of 12 trials on 12 separate days. FIRGURE 21.18 shows their results. FIGURE 21.18 Attracting mosquitoes. The graph shows that the number of mosquitoes (out 100) attracted to uninfected children, children harboring the aseoual stage of Plasmodium, and children with gametocytes in their blood. The bars show the average number of mosquitoes attracted to that category of child over the course of 12 separate trials. On average, which group of children was most attractive to mosquitoes?
Testing Biological Control Ant-decapitating phorid flies are just one of the biological control agents used to battle imported fire ants. Researchers have also enlisted the help of Thelohania solenopsae, another natural enemy of the ants. This microsporidian (Section 23.4) is a parasite that infects ants and shrinks the ovaries of the colony's egg-producing female (the queen). As a result, a colony dwindles in numbers and eventually dies out. Are these biological controls useful against imported fire ants? To find out, USDA scientists treated infested areas with either traditional pesticides or pesticides plus biological controls (both flies and the parasite). The scientists left some plots untreated as controls. FIGURE 45.28 shows the results. FIGURE 45.28 A comparison of two methods of controlling red imported fire ants. The graph shows numbers of imported fire ants over a 28-month period Orange triangles represent untreated control plots. Green circles are plots treated with pesticides alone Black squares are plots treated with pesticide and biological control agents (phorid flies along with a microsporidian parasite). 3. If this study had ended after the first year, would you conclude that biological controls had a major effect?
