Abstract
The present study undertakes to evaluate the effect of used cationic new nano surfactant ((1-(2-chlorophenyl) diazane hexadecyl trimethyl azane, bromo trichloro cuprate(II) complex(S)) upon addition to synthetic Azobenzene-hydrazone Derivatives ((E)-2-oxo-2-((4-((Z)-phenyldiazenyl)phenyl)amino)-N-(4-(N-(thiazol-2-yl)sulfamoyl)phenyl)acetohydrazonoyl cyanide (1) and ((E)-N-(4-(N-(4,6-dimethylpyrimidin-2-yl)sulfamoyl)phenyl)-2-oxo-2-((4-((Z)-phenyldiazenyl)phenyl)amino) acetohydrazonoyl cyanide (2). The physico-chemical properties for adjuvants and formulations were both determined separately. The effect of these synthetic complexes formulations has been measured against 3rd instar larvae of cotton leafworm, Spodoptera littoralis (Boisd.) and against two spotted spider mite, Tetranychus urticae Koch, LC50s and LC90s values were measured and tabulated under semi field conditions. The results indicated that, the surface tension and pH values of the spray solution decreased in the two formulations. Results showed that coated 1and 2 with applied cationic nano surfactant gave highest increase in the insecticidal activity than 1 and 2 alone solutions. These results indicated that cationic adjuvant (S) increased the effectiveness of formulations. Therefore, cationic adjuvant (S) may be used to reduce the number of applications per season and the application rates of chemicals works as insecticides. The toxicity index as well as enzymes activity must be considered when investigating the total effects of new tested chemical formulations. Therefore, the aim of the present work is to clarify toxicity and the role played by the sub lethal dose LC50 of two new synthetic chemical formulations on the 3rd instar larvae of S. littoralis and two spotted spider mite Tetranychus urtica Koch, in order to better understand of the action of these compounds on lepidopterous larvae and spider mite through studying their effect on biochemical parameters. These parameters are attained by estimating activity of some enzyme affecting in cuticle formation.
