littoralis larvae (lab and field strains) were treated with solution of Cyhalothrin and Chlorpyrifos at different concentrations before 24, 48, and 72 hrs of feeding on discs of castor oil leaves discs treated with tested fertilization, joint action experiments have two controls.
The results of the toxicity of the Cyhalothrin and Chlorpyrifos in terms of [LC.
50] values of Cyhalothrin and Chlorpyrifos pretreated with the tested fertilization (Urea, Superphosphate, and Potassium sulphate) on lab and filed strains of Spodoptera larvae are presented in Table (2).
Cyhalothrin when pretreated with Superphosphate were the most toxic treatments than pretreated with Potassium sulphate, and Urea respectively, while Chlorpyrifos when pretreated with Urea were the most toxic treatments than pretreated with Superphosphate, and Potassium sulphate respectively, these results are in agreement with which found by many [7,19,17].
The observed changes in behavioural, hematologic, biochemical, tissue and mortality patterns of exposed toads to sub-lethal doses of field grade Lamda Cyhalothrin pesticide used for agricultural purposes further implicates the role of uncontrolled agricultural run offs in amphibian declines and in extension the vulnerability of all other aquatic lives.
