Duration of developmental stages of Lycoriella ingenua reared on different mushroom mycelia at different temperatures.
The duration of the egg, larval and pupal developmental stages of Lycoriella ingenua reared on mycelia of five edible fungi (Agaricus bisporus, Pleurotus ostreatus, Auricularia polytricha, Agrocybe cylindracea and Flammulina velutipes) under four different temperature regimes (15, 20, 25 and 30°C) were determined. In all cases, the time required for full development was shortest at 25°C although the duration times of individual stages were occasionally shorter at 20°C. At any given temperature, the duration of the combined developmental stages was longest when L. ingenua was reared on A. polytricha mycelium and shortest on F. velutipes mycelium. Significant differences were observed in the developmental threshold and effective accumulation temperatures for L. ingenua reared on the different fungal mycelia, with highest values recorded for A. polytricha.
