highly significantP =0.022
Highly significant differences in larval mortality occurred as early as 48 h after the eggs were laid in the 0.6 M and 0.8 M ( Fig. 3 , Mantel-Cox: 0.6 M, x 2 =5.24, P =0.022; 0.8 M, x 2 =10.39, P =0.001) and 72 h after the eggs were laid in the 0.4 M, 0.6 M and 0.8 M (Mantel-Cox: 0.4 M, x 2 =4.47, P =0.035; 0.6 M, x 2 =11.81, P =0.001; 0.8 M, x 2 =11.88, P =0.001).
