1 Recitation Activity III KEY Chemistry 121 Chapters 3 & 4 The Praying Mantis is a carnivorous insect that has been exploited in order to control “unwanted” insects in the garden. Several gardening companies sell mantids for profit. Let’s say that you, an entrepreneur, are looking for an idea for a new business. reference - http://www.insecta-inspecta.com/mantids/praying/ If you want to produce Praying Mantids to sell to the general public (for profit), you need to learn a few basics about successful mantid breeding. The Golden Rule: Hungry female mantids have a nasty habit of eating male mantids (usually head first). Therefore, to insure success in the mating process both female and male mantids should be well fed for many days before the male and female cohabitate the same cage. For the purpose of this experiment, we will introduce 2 fully fed female mantids and 5 ‘hungry’ female mantids for mating to 1 very randy, and already fed male mantis. To simplify the problem let’s make the following assumptions: #1: A fed male will always mate if a female is available (ignore parallels to human behavior). #2: If given a choice the male will ALWAYS mate with a female who is fed before he mates with a female that is hungry (wouldn’t you do the same thing if you were a male mantis?). #3:A Female mantis will only eat her mate if she is not fed. #4:A Female mantis will only eat a male AFTER she has mated with him. The mating of the mantids is analogous to a chemical reaction since the product of the mating is ~12 to 400 eggs, depending on the mantis species. We will also assume for simplicity that each female mantis that successfully breeds will produce 100 mantis eggs. The overall reaction is shown in Equation (I):
