| Abstract |
This study was carried out in three successive seasons (2000,2001 and 2002,respectibvelly) at Mallawi (Minia), Sids (Beni-Suef)and EI-Kharga (New Valley) regions to evaluate the efficiency of the egg-parasitoid, Trichogramma evanescens as
a biological control tool , at rate of 0 , 10000 , 20000, 30000 wasps/fed. , compared with Lannate insecticide at 300 and 150 g/ fed. , against the bean pod borer, Etiella zinckenella Treit. in soybean fields. The results indicated that the soybean plants treated with the egg- parasitoid and insecticide significantly reduced the percentage of infesed soybean pods , seeds and resulted in a higher seed yield the highe egg¬parasitoid or insectcide was the lower infestation obtained.The highest rate of parasitoid (30,000 wasps/ fed.) or Lannate 90% (300g Ifed.)were highly effective in decreasing the pod infestation. Highly increasing in seed yield / fed. by (34.6, 38.6, 30.0%) and (36.4, 39.1, 30.9 %) during the in three season, respectively. On other hand , no significant differences was observed in pod and seed infestation between the plants significant with the highest rate of egg parasitoid and plants treated with Lannate insecticide in the recommended -dose 300 g/ fed. While, the lowest rate of parasitoid (10,000 wasps / fed.) or Lannate (150g Ifed.)were least effective with low increasing in seed yield/fed (20.5, 14.8 , 15.0) and 23.8 , 21.2 15.5 %) in three regions , respectively.There were positive correlation between percentage of pod infestation and seed yield in all treatments. All treatments caused significant increase in number of seeds per plant and seed yield per plants and feddan. This increas was high in plots treated with the highest rate of egg parasitoid or with Lannate insecticide, and low in plots treated with the lowest rate of egg parasitoid or with Lannate insecticide compared with the control.. Therefore, the local egg- parasitoid, T. evanescens as rate of 30000 wasps / fed. can be successfully applying against E. zinckenella. in soybean fields as an effective and safe agent
