Toxicological Studies on the Cotton Spiny Bollworm, Earias insulana Bois. (Lepid., Arctiidae) in Iraq
View through CrossRef
AbstractThe toxicities of 13 hydrocarbon, organic phosphates and carbamate insecticides to the cotton spiny bollworm Earias insulana Boisd., were determined by topical application. The results showed that of the insecticides tested Folidol M50, Matacil, DDVP and Gusathion AM were the most toxic to the spiny bollworm. Endrin and Carbaryl were the least toxic. Also results indicated strongly that the spiny bollworm is resistant to the chlorinated hydrocarbon insecticides.An experiment was conducted to determine the effect of post‐treatment temperature on the individual toxicity of Folidol M50 and Matacil to the cotton spiny bollworm larvae. The results showed that the post‐treatment temperature had a marked effect on the toxicity of the two insecticides tested: the higher the temperature the higher the toxicity.ZusammenfassungToxikologische Studien an der Baumwollkapsel‐Eule Earias insulana Bois.Es wurde die Wirkung von 13 Hydrokarbon‐, Organophosphat‐ und Carbamat‐Insektiziden auf die Raupen von E. insulana bei individueller äußerlicher Applikation (2 Mikroliter/Raupe) untersucht. Folidol M50, Matacil, DDVP und Gusathion AM zeigten die höchste Wirksamkeit, Endrin und Carbaryl die geringste. Die Ergebnisse ließen eindeutig erkennen, daß der Schädling gegenüber den Chlorkohlenwasserstoffen resistent ist.Experimente ergaben, daß die Temperatur nach der Behandlung auf die Toxizität von zwei daraufhin geprüften Insektiziden (Folidol M50 and Matacil) Einfluß nahm: die Toxizität stieg mit der Temperatur an.
