The non-pollinating wasp of Philotrypesis sp. is parasitic in Ficus pumila. The oviposition process of Philotrypesis sp. was recorded with a digital camera in the experiment,which can be divided into three periods,searching oviposition site,the oviposition stylet penetrating into the syconinum to oviposit and pulling out the oviposition stylet. The oviposition stylets were longer than the syconial thickness,and penetrate into the syconial wall along syconial diameter as the shortest way,whereas the paths in...
