Abstract

Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract mates, Japanese beetles release pheromones to attract more beetles, and ants release pheromones along an ant trail. Put a beetle in a cup with holes poked in it to see if it can attract more beetles. Wipe through a trail of ants with a baby wipe to see if you can erase the pheromone and see how long it takes the ants to recover the trail. Place some rotting fruit out to see if it will attract some fruit flies. Will artificial scented oils attract or repel insect? Try oils like cinnamon, citronella, orange oil, rose oil and almond oil. Which oils act as attractants and which as repellents? (Dashefsky, 1995, 2-3, 7-9)

Zoologist and Wildlife Biologist

Ever wondered what wild animals do all day, where a certain species lives, or how to make sure a species doesn't go extinct? Zoologists and wildlife biologists tackle all these questions. They study the behaviors and habitats of wild animals, while also working to maintain healthy populations, both in the wild and in captivity. Read more

Biologist

Life is all around you in beauty, abundance, and complexity. Biologists are the scientists who study life in all its forms and try to understand fundamental life processes, and how life relates to its environment. They answer basic questions, like how do fireflies create light? Why do grunion fish lay their eggs based on the moon and tides? What genes control deafness? Why don't cancer cells die? How do plants respond to ultraviolet light? Beyond basic research, biologists might also apply their research and create new biotechnology. There are endless discoveries waiting to be found in the field of biology! Read more
