| Abstract | ||||
| Laboratory evaluations were conducted on newly adult stage (gonadotrophic period) of Schistocerca gregaria (Forskal), treated with pyrazole, an aromatic juvenile hormone analogue to clarify disruption of the embryos growth. Data indicated that a correlation exists between the type and concentrations on proteins and dosed females. Such effect was considered as a juvenilizing action of JHA on these vital metabolites due to their indirect effect on the natural level of juvenile hormone in the treated adults. Biochemical evidence appears that depression of total protein level 96.3% during last embryonic development stages. Concentrations of the aromatic and non-aromatic amino acids such as Marline , Arginine Lysine , Praline , Glutamine, Tyrosine, Glysine, Isoleusine, Histidine, Cystin, Glutamic and Phenylalanine, may be limiting factor of the growth of the material tissues during differentiation of organs development in embryos. It appears to be involved more in the metabolism of the embryo and expressed as a dramatic curtailment of growth of embryos. | ||||
