Abstract EN
The study was aimed to measure the effectiveness of predator Chrysoperla carnea in reducing the population of whiteflies Bemisia tabaci on eggplant crop in greenhouses.
In 2013, the lacewings predators were released on eggplant crop in greenhouse at rate of 20, 40, 80, 100, 150 and 200 eggs / 2m distance; 25, 50 and 75 larvae / 2m distance; and 5 larvae / plant in comparison with the insecticide Esters as well as the control treatment.
Results were measured after seven days.
The highest efficiency was achieved by releasing 50 larvae /2 m (58%) without significant differences from the efficacy of insecticide - Aster (62%) and both were did not differ significantly from the effect of 75 larvae / 2m , 100, 150 , 200 eggs /2 m and 5 larvae / plant.
Weakest results were by releasing 20 eggs / 2m, but it did not differ significantly from 40 and 80 eggs / 2m.
Generally the efficiency of the predator increased with increasing of nymphs’ population density at a decreasing rate with the increasing of population density during the season.
