We rear not to kill but to understand the biology of the organism in order to protect it. To begin with, we may need to know what it feeds on. We may then need to find out the duration of each of its development stages etc. These foundamental data can help decision makers to work out conservation plan or on a less positive side, to avoid causing damage to its habitat.
After rearing, one can always release the insect back to the wild. So taking specimens for rearing is not always a bad thing.
