THE EFFECT OF IVERMECTIN ON THE HATCHING OF AEDES MOSQUITO EGGS

Abstract

This study aimed to investigate the hatching inhibitory effect on eggs of Aedes aegypti mosquito of Ivermectin solution. According to concentration of  Ivermectin solution, the experimental groups were divided into 6 groups including (i) 0 ppm, (ii) 0.001 ppm, (iii) 0.01 ppm, (iv) 0.1 ppm, (v) 1 ppm, and (vi) 10 ppm respectively. Twenty five eggs of mosquito were submerged in 150 mL of Ivermectin solutions for 48 hours. The experiment in each group was triplicates. The number of hatched eggs at 48 hours among groups of 0 ppm, 0.001 ppm, 0.01 ppm,  0.1 ppm, 1 ppm, and  10 ppm Ivermectin were 20+0.00, 8.33+7.57, 7.33+0.58, 6.33+1.53, 5.67+4.16, and 4.33+5.13 respectively. Moreover, the percentage of hatching inhibition were 0%, 58.35%, 63.35%, 68.35%, 71.65, and 78.35% respectively. The IC₅₀ of Ivermection for Aedes eggs hatching was less than 0.001 ppm. These findings suggested that Ivermection solution  inhibits the hatching of Aedes eggs into larvae.
