Abstract:

The different forms of use of giberic acid (GA3) applied in orange are the orange unlubiti (Planococcus citri(Risso) (Hom.Cryptolaemus montrouzieri Muls used in its biological struggle. (Col: Coccinellidae) and Leptomastix dactylopii How (Hym.The effects on Encyrtridae have been determined in the laboratory. The GA3 character used in the trial did not have a toxic effect on the different periods of P.citri. Agrowett (AW) and GA3+AW, a mixture of other characters, prevented the opening of P.citri’s eggs by 12-20%, the contact of the second and third period nimphs by 16.8-17.8%, and the infection capacity of these nimphs by 17.3-19.7%. Again, the GA3, AW and GA3 + AW of the C. montrouzieri's egg opening and the adult, L. The result was that dacylopii’s guest parasitization did not have any toxic effects according to the classification IOBC accepted in laboratory trials for benefits.
