Abstract
Effect of two antimoulting compounds against the larvae of Spodoptera littoralis (Boisd.)
Dc 201 and 202 are representatives of a new class of insecticides. Susceptibily of three instars ofSpodopteram littoralis (i.e., 1st, 3rd, and 6th) is demonstrated. Their insecticidal activity demmonstrates itself as a failure to moulte or pupate, resulting in death. Treated larvae remained seemingly unaffected until they had entered the apolytic stage preceding the actual sheding of the exuvia.
Dc 202 was more active and more persistant on treated cotton plants than DC 201, particularly at the lower oncentration; the residual activity of the former compound extexded much longer than 15 days.
