| Abstract | ||
| This work was conducted to study the biological impact of releasing the Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) and Orius albidipennis (Reuter) (Hemiptera: Anthocoridae) to control Thrips tabaci Lindeman, and Aphis spp. infesting strawberry plants under open field conditions. Experiments were carried out during the period from November 13, 2015 till the mid of June 2016 at El- Beregate area 30 km South Kom Hamada center, El-Behera Governorate, Egypt. The obtained results indicated that, releasing of Chrysoperla carnea with 15 individuals at 2nd instar larvae recorded the highest mean reduction percentage (97.3%) against the aphid pest, while the highest reduction percentage of thrips insects was recorded at the treatment of releasing with five individuals of 2nd instar nymph of Orius albidipennis with mean reduction percentage of 98.5%. The second larval instar of C. carnea caused reduction percentage in the aphid population reached to 100% during last week of December, 2nd half of February and 3rd week of March, while at other weeks, the reduction percentages ranged between 84.2% (2nd week of December) and 99.1% during most weeks of the study period. | ||
