Many of mimic analogues synthesized before depending on the change in the structure of aromatic rings. In this work, the carbonyl group in the structure of compounds 1-4 converted to thiocarbonyl group, and then studying the toxicological activity due to chemical change in the active center of mimic analogues was performed for compounds N-tert-butyl-2,4-dichloro-N'-(2,4-dichlorobenzoyl)benzohydrazide (2) and N-tert-butyl-2,4-dichloro-N'-[(2,4-dichlorophenyl)carbonothioyl]benzenecarbothiohydrazide (6). The toxicological study was done by using 2nd and 4th instar larvae of the cotton leaf worm, Spodoptera littoralis (Boisd.). Five concentration levels (600, 300, 150, 75 and 37.5 ppm) of compounds (2) and (6) were applied on the fresh plant food to the newly grown (2nd and 4th) instar larvae.

A field study were conducted to evaluate the efficacy of the entomopathogenic fungi Beauveria bassiana as abiocontrol agent for the cotton leaf worm Spodoptera littoralis infesting potato plants. Results indicated that soil treatment of the entomopathogenic fungi significantly reduced the percentage of plant infestation to 64.3, 60.7 % after 14, 21 days. Results of the infection intensity also significantly reduced in treatment of entomopathogenic fungi in soil to 18.7, 9.9 pore/leaf after 14, 21 days of treatment.The results revealed the higher efficiency of entomopathogenic fungi on plant yield, it become 633.3 gm in entomopathogenic fungi in soil treatment.
