Humoral encapsulation (“melanization”) represents the predominant defence reaction of Chironomus larvae against injected bacteria. Only low levels of phagocytic activity were observed; cellular encapsulation and nodule formation were completely missing due to low numbers of haemocytes. No other humo...
