This bee, Osmia ribifloris (on a barberry flower), is an effective
pollinator of commercial blueberries and is one of several relatives of
the blue orchard bee, Osmia lignaria. Similar in appearance, the blue
orchard bee is also a successful commercial pollinator that is now being
evaluated for use in a wider range of crops. Photo by Jack Dykinga. |

Fire ants will do anything to resist attack by the tiny phorid fly
measuring only about one-sixteenth of an inch. A highly specific
natural enemy, the female pierces a fire ant's head and releases an
enzyme that later decapitates it. Photo by Sanford Porter. |

The production of medflies can be realized in the laboratory by bathing
medfly eggs in warm water—a process that kills the female embryos but
doesn't harm the male embryos. In the pupal stage, the males can be
irradiated to render them sexually sterile. Photo by Scott Bauer.
