Textbook Question
Chapter 45, Problem 3DAA
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
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?

In the transfer diagram, ^ is the rate at which individuals are born, p is the fraction of
infants who are vaccinated, ß is the rate at which susceptible individuals become infected
by those who are infectious, is the natural death rate, o is the rate at which exposed
individuals become infectious, and is the rate at which infected individuals are treated
and recovered with permanent immunity.

But one day, I notice that Stretch is really stretching out! And a few minutes later, Stretch has turned into two. Amoebas reproduce through mitosis, where they replicate all of their internal biology, then split themselves into two, each new cell carrying everything it needs to survive. Which one is Stretch? Both? How can that be, since things are only identical to themselves? We wouldn't call identical twins the same person, even though they are very similar to one another. Are neither Stretch?
