A laboratory study was carried out to evaluate the effectiveness of the chemical pesticides Actara, Abamectin, Oxymatrim, and two bioformulation Varanestra (V. lecanii) and Almite (H. thompsonii) and their combination on adults and pupae of the Liriomyza bryoniae. The results showed that the most compatibility pesticide with V.lecanii and H.thompsonii were Actara, while Abamectin and Oxymatrine did not showed compatibility with these fungi.
The treatment of Abamectin was superior in adult mortality 55.56% at the half-field concentration (FC-50%), followed by Actara was 46.67%, while the lowest mortality percentage of Oxymatrine treatment was 38.89%. The treatment of Varunestra was significantly higher in mortality percentage of adults was 55.60%, while the lowest mortality percentage for Almite treatment was 42.20%. There was no significant difference in adults mortality percentage for both the mixture (Actara + Varunestra) and the mixture (Actara + Almite), which reached 56.66% and 52.22%, respectively.
The treatment of the mixture (Actara + Varunestra) was superior In reducing adults emergence percentage from pupae of 8.88%, which did not differ significantly from the treatment of the mixture (Actara + Almite), which reached to 12.22%.Results showed that Actara was compatibility with two bioformulation Varanestra (V.lecanii) and Almite (H. thompsonii) to control adults and pupae of the Liriomyza bryoniae
