| Abstract | ||||
| Six inorganic salts were evaluated as possible sterilants against the cotton leaf worm, Spodoptera littoralis, by applying the pupal dipping technique. Results showed that all of the tested salts adversely affected the adult emergence and reduced the egg laying capacity and egg hatchability. The salts, NaoH, Ca (oH)2 and ZnSO4 gave 100% percent sterility with all tested nontoxic concentrations. Percentage of sterility increased with the increase of the concentration. All other salts induced degrees of sterility ranging from 55 to 75%. Treatment with these inorganic salts also caused several malformations in pupae and resulted moths. | ||||
