For the cecropin and lysozyme genes, we observed increased expression in the fat body at 15 °C compared to 25 °C (effect of temperature, H1,19 = 3.9, p = 0.05 and H1,23 = 3.2, p = 0.07, respectively), and more active expression in response to fungal infection was also observed at low temperature (Figure 5). This evidence concerns the gene LYZ and fungal infectious disease.
