Terms | Definitions |
|---|---|
 entomology | the study of insects and other terrestrial anthropods |
| labrum | mouthpart that functions like an upper lip |
| labium | mouthpart that functions as a lower lip |
| tympanum | sound-sensing organ |
| ovipositor | part of the female abdomen that forms a point and is used to dig a hole in soil to lay fertilized eggs |
| metamorphosis | developmental change as insects grow into adults |
| incomplete metamorphosis | a nymph hatches from an egg but is smaller; it goes through a series of molts, each time looking more like an adult, until it reaches full size |
| molt | to shed an outer covering |
| complete metamorphosis | insect development consists of 4 stages: egg, larva, pupa and adult; complete metamorphosis is the larva and pupa stages when the insect looks substantially different from an adult |
| nymph | an immature form of an insect that looks like an adult but is smaller |
| pupa | an insect changes from a larva into an adult |
| pheromone | chemical substance released by an animal (especially insects) that affects the behavior or development of other members of the same species through their sense of smell or taste |
| social insects | insects that live in colonies where some gather food, some protect the colony and others reproduce |
| innate behavior | genetically determined behavior |
| worker bees | nonreproductive (sterile) females that make up the vast majority of the hive population |
| queen bee | the only reproductive bee in the hive, and her only function is to reproduce |
| drones | males that develop from unfertilized eggs |
| royal jelly | a high-protein substance that is fed to the queen and the youngest larvae |
| queen factor | it decides s whether a fertilized egg will develop into a worker and prevents other female larvae from developing into queens |
| kin selection | a mechanism of propagating one's own genes by helping a closely-related individual to reporduce |
| 3 ways that insects communicate with examples | (1) pheromone helps ants find their way back to the nest; (2) social insects in colonies - some reproduce, some gather food and some protect the colony; (3) queen factor is a pheromone that prevents other fertilized larvae from developing into a queen |
| The thing that determines whether a fertilized honeybee egg will develop into a worker or a queen | The queen factor determines whether a fertilized egg will develop into a worker. |
| When a beehive is overcrowded this is how honeybees behave. | The queen leaves the hive and leaves a pheromone only allows half the worker bees to follow her to a new hive. |
| How honeybees convey information about the direction and distance of a food source that is far from the hive. | They either do the round dance or the waggle dance. |
| round dance | honeybee dances in a circular motion, indicating that food is nearby |
| waggle dance | honeybee dances with wiggle-type movements, indicating that food is far away |
