Bean beetles, Callosobruchus maculatus, get their lifetime nutrition from the bean seeds (family Fabaceae) on which their mother lays her eggs. The specific bean on which each egg is laid determines the future success of the larva that develops from that egg. Choosing where to lay an egg is the most important decision a female bean beetle will make for her offspring, yet even within one bean species the seeds available may be very different in quality. Seeds vary in size (even if from the same plant), so the amount of resource available to larvae on different beans will not be the same. Seed mass may vary by as much as 50% among mung beans purchased in a local store, a species on which Callosobruchus develops normally and may complete its lifecycle. Given the problem described above, what do you predict if the alternative hypothesis is true? If the mass of all the beans are the same, then the larvae will be successful. If the mass of the bean varies, then the larvae will be successful for all masses of bean. If the quality of the bean varies, then larvae will be equally as successful. If beans of large and small size are tested, then larvae will be successful for both sizes of bean. If the mass of the beans vary, then the larvae will be successful on beans of one mass over another.
