Ladybugs are common insects in North American gardens that prey upon aphids, making them all the rage in biological pest control. Ladybugs can be bred in captivity making them a good insect to study. Just chop off an aphid infested plant stem for food, make a water soaked cotton ball for water, and add to a small plastic container with a lid to make a breeding box. You can use ladybugs collected from the wild, or buy ladybugs from your local nursery. The most common species is the 12-spotted ladybug, but there are also the seven-spotted European ladybug common in Europe and the nine-spotted ladybug common in Southeastern US. Recently, the Asian ladybird beetle has been introduced as an invasive species and competes with native Some species have a constant number of spots, while others have a variable number of spots in the population. You can breed ladybugs to find out if spot number is a heritable trait. You can also investigate the generation time and reproductive biology of ladybugs.

Career Profile
Why is it that certain breeds of cattle produce more flesh or milk? Why is one horse faster than another? The answer is that these breeds were engineered to have these special characteristics. Animal breeders need to understand genetics in order to produce animals that are bigger, faster, or more beautiful. If you are interested in working with animals and are fascinated by the science of genetics, then you should investigate this career. Read more
Career Profile
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
