In: Agricultural Research Journal, Suez Canal University 2004 v.4(2)Summary: The bethylid parasitoid Goniozus Legneri Gordh ,was introduced from U.S.A in 1997 as a bio-control agent against the pyralid pest Palpita unionalis (Hb.) attacking olive frees in Egypt. The present paper deals with its Biology. The four constant temperatures, 15, 20. 25 and 30 ºC; each combined with 60±5 % R.H. were used to estimate the durations of immature stages and activity of adult reproduction. The temperature showed a significant effect on each parameter. The most favourable hygrothermic condition are 30 ºC and 60 %R.H. The longevity of mated and unmated parasitic individuals were also estimated under different temperatures and feeding regimes. It was significantly affected by such factors.
