The present study was carried out for two seasons 2015/2016 and 2016/2017 on sugar beet ,fodder beet ,table beet and chard sown at the experimental farm of Sakha Agricultural Research Station . Kafr El –Sheikh , Egypt .The average number of  P. mixta eggs were recorded the highest average on fodder beet followed by table beet, sugar beet and chard during the first season 2015/16 and represented by 157.2+3.3, 93.9+3.5, 89.04+6.4 and 45.5+4.8 eggs, respectively. The average number of P. mixta eggs were recorded the highest average on fodder beet followed by table beet, sugar beet and chard during the second season 2016/17 and represented by 150.4 ±6.1, 96.6 ±4.2, 59.7 ±3.0 and 40.3 ±4.7 eggs, respectively. The highest average number of P. mixta larvae were recorded on fodder beet plants followed by sugar beet plants, table beet plants and chard during the first season 2015/16 and represented by 85.5 ±4.2, 54.02 ±3.5,41.1+5.3 and 27.7±6.5 larvae, respectively. The highest average number of P. mixta larvae were recorded on fodder beet plants followed by table beet plants, sugar beet plants and chard plants during the second season 2016/17 and represented by 96.4 ±5.2, 57.7 ±3.9, 48.9 ±4.4 and 22.3 ±3.1 larvae, respectively. Fodder beet attractive the highest average number of the parasitoid followed by sugar beet and chard during the first season 2015/16 and represented by 9.9 ±1.96, 9.4 ±2.8, 7.2 ±1.9 indiv., respectively. Moreover table beet plants came in the last category and attractive the lowest average number of the parasitoid and represented by 4.3 ±0.7 indiv. Sugar beet attractive the highest average number of the parasitoid followed by chard and fodder beet, during the second season 2016/17 and represented by 11.8 ±2.1, 9.0 ±1.2 and 7.5 ±0.6  indiv., respectively. Moreover, table beet plants came in the last category and attractive the lowest average number of the parasitoid and represented by 4.1 ±0.9 indiv.  Fodder beet came in the first rank with an average percentage of parasitism 14.9% followed by sugar beet 14.2% and table beet 10.7%, while chard plants was the least average percentage of parasitism 9.8% in the first season 2015/2016 . Sugar beet came in the first rank with average percentage of parasitism 17.1% followed by fodder beet 11.6% and table beet 11.4% while chard plants came the least average percentage of parasitism 10.9% in the second season 2016/2017.
