Abstract :
Lufenuron (chitin synthesis inhibitors) and Oryza sativa bran extract (waste product) exhibited insecticidal activity on females of Schistocerca gregaria when they were treated as one day old of the 5th nymphal instar with different concentrations of tested compounds. Some biological aspects, failure of ecdysis to adults, adult mortality, prolongation in the age of last nymphs and developmental events were investigated after treatment.
Quantitative and qualitative determination of protein and DNA contents were investigated in normal and affected eggs which resulted from females Schistocerca gregaria treated as one day old 5th nymphal instarwith LC50 ofLufenuron and Oryza sativa bran extract during embryogenesis. The total protein content of normal eggs at 0-day old, was 81.07 mg protein/gm eggs, after one day of oviposition the total protein increase significantly (p
