This study discusses the behavior of the females of the parasitic wasp Nasonia vitripennis, which adjust the sex ratio of their broods according to whether or not they are the first or second wasp to parasitize a host. The results provide a quantitative test of sex ratio theory. (Author/SA)

Discusses reasons for the success of insects, considering their size, reproductive ability, development, and adaptability. Also discusses various types of insect "homes" (such as galls and paper nests). (JN)

Describes a study using two genera of aquatic insects that demonstrates how nonlethal falls in oxygen concentration affect the rate of surfacing of bottom-feeding Coroxidae and how this affects their survival by increasing their proneness to attacks by surface-feeding Notonectidae. (CS)

Bugs fascinate children, and each kind of bug plays a special role in the circle of life. Some bugs pollinate plants, while others help to decompose plant and animal waste. In this videotape, students learn about the similar characteristics that all bugs share and compare them to their close cousins, the arachnids. This videotape correlates to the…
