Melon fly eggs, larvae, or pupae were homogenized with four volumes of PBS. The homogenates were then centrifuged at 20,400×g for 30 min at 4°C and the sugar content of the supernatants were measured using the phenol-H2SO4 method. RAW264 cells were incubated with these diluted supernatants for 20 h and the nitrite levels in the culture medium were measured by Griess assay.
