Whether the occurrence of these two death peaks can be prevented or avoided is the key to success or failure of prickly heat. First, the auricles “rotten stomach” - the first death peak “rotten stomach” occurs mainly in the big ear period, beginning larvae often thickening of the stomach wall, rough, the boundaries of the stomach ambiguous, and then shrink deformation, severe When the entire stomach ulcer broken, most of the larvae in metamorphosis
