Biological and insecticidal effects of total glucosinolates and different extracts of carrichtera annua [L.] DC. and farsetia aegyptia turra. on spodoptera littoralis [Boisd.]

ABSTRACT

Different extracts of Carrichtera annua and Farsetia aegyptia as well as theirglucosinolates were prepared and the efficacy of these extracts and totalglucosinolates was studied against the Egyptian cotton leafworm, Spodoptera littoralis. Aqueous extracts and total glucosinolates of both plants wereremarkably toxic against Spodoptera littoralis larvae. They exhibited strongantifeedant effect against the 4th instar larvae and proved to be the mostpotent extracts as compared to all other tested ones, where the ovipositionalrepellent effect reached 100%. Larval growth and development weresignificantly affected and no pupae were developed
