Acute toxicity of insecticide, Diazinon and fungicide, Tilt (Propiconazole) on Pacific white Shrimp, Litopenaeus vannamei postlarvae and Palaemon adspersus juveniles
Journal Title: Journal of Research in Biology - Year 2012, Vol 2, Issue 3
Abstract
Acute toxicity of Diazinon and Tilt (Propiconazole) agricultural toxins was studied on Litopenaeus vannamei postlarvae and Palaemon adspersus juveniles, aiming to determine the 50% lethal concentration (LC50) in 96 h time duration. The experiments were conducted at static condition and standard method in four days. Physical and chemical factors were controlled through the experiment so that the amount of dissolved oxygen was fixed on 8 mg/L, temperature: 25 ± 1 0C, pH: 7.5 to 8 and salinity: 31 ppt. The results showed that the mean LC50 values of Diazinon at 24, 48, 72 and 96 h were 0.298, 0.255, 0.237, 0.226 mg/L, and the mean LC50 values of Tilt at 24, 48, 72 and 96 h were 9.021, 4.227, 4.032, 3.635 mg/L, to the Litopenaeus vannamei postlarvae. Also, the results showed that the mean LC50 values of Diazinon at 24, 48, 72 and 96 h were 0.391, 0.330, 0.294, 0.277 mg/L, and the mean LC50 values of Tilt at 24, 48, 72 and 96 h were 0.789, 0.763, 0.674, 0.611 mg/L, to the Palaemon adspersus juveniles
