Encapsulation is a general mechanism involved in the immune cellular reaction during pathogen resistance in insects. As insects have no specific-immunity, this kind of response is potentially mounted against any kind of foreign body able to wound or infect them. Different types of immune responses will be tested and compared with individuals injected with a non-pathogenic bacterium (E. coli), PBS, and naïve. The immune assays used include those commonly used in other invertebrates: encapsulation rate, haemolymph assay (haemocytes count), phenol oxidase and lysozime-like activity. Eclosion rate will be assessed for a subset of treated and non-treated samples, for which also wing-darkness will be analyzed.
