The influence of feeding histories on the food selection of the German cockroach is reported. Adult cockroaches were fed with one of three types of foods, rice bran, dried fruit (apricot), and a dried meat product (dog food jerky), for 18,10,or 5 days before 2 days of starvation. They were then allowed to feed freely on two of the three, including the food experienced just before. The cockroaches usually preferred the other food to the experienced, or more liked the other than before. Nymphs also showed similar responses.
