Table 1.

Factors that might influence oviposition efficiency of foundresses (oviposition efficiency: galled flowers per foundress), (mean ± s.e.). The experimental data showed that the lifespan of the pollinator was strongly affected by the temperature and humidity of environmental conditions [24,39], which might result in the oviposition efficiency difference between morning and afternoon, or between warm and cold season. The data in this table also show that the fruit diameter will significantly affect the oviposition efficiency of each foundress, conforming to the correlation analysis result in §3. Here, O/F is the offspring (gall) number per foundress, and FD is the fruit diameter (millimetre).
