“…As for the recently developed pesticides such as insect growth regulators (IGRs) or/and synthetic pyrethroids, very few attempts have been made to ascertain their ovicidal action (ASCHER and NEMNY 1974; ABO-ELGHAR et al 1976;AYAD and BISHARA 1976;TYSOWSKI and GALLO 1977; ABO-ELGHAR et al 1980).…”

The ovicidal activity of 4 synthetic pyrethroids and 2 insect growth regulators compared with Chlorpyrifos and Methomyl were investigated by topical application against Spodoptera littoralis eggs of different ages. Synthetic pyrethroids exhibited highly pronounced ovicidal action much better than organophosphate and carbamate compounds used as standard, and Decamethrin revealed the highest activity in this respect. The chitin biosynthesis inhibitor Diflubenzuron evoked ovicidal activity higher than both of standards and its analog Trifluron (BAY SIR 8514). In all cases, as the egg‐age or/and embryonic development was considered, the more developed eggs (2–3 days old) were less sensitive than newly developed eggs (0–1 day old). Zusammenfassung Unterdrückung des Eischlüpfens bei Spodoptera littoralis mit Insektenwachstumsregulatoren und synthetischen Pyrethroiden Es wurden die oviziden Wirkungen von 4 synthetischen Pyrethroiden und 2 Insektenwachstumsregulatoren, verglichen mit den herkömmlichen Insektiziden Chlorpyrifos und Methomyl, bei Eiern von S. littoralis verschiedenen Alters unter Anwendung topikaler Applikation getestet. Die synthetischen Pyrethroide zeigten viel ausgeprägtere ovizide Wirkungen als die beiden Kontrollpräparate, wobei Decamethrin am stärksten wirkte. Der Chitinsynthese‐Hemmstoff Diflubenzu‐ron zeigte stärkere Ovizidität als die beiden Kontrollwirkstoffe und sein Analogon Trifluron (BAY SIR 8514). In allen Fällen waren die bereits weiterentwickelten Eier (2–3 Tage alt) weniger empfindlich als die frischabgelegten Eier (0–1 Tag alt).
