A. The time to release in days for cysts and nauplii from females injected with control solution (a, c) and p26 dsRNA (b, d) for broods 1–4. a, nauplii; b, nauplii; c, cysts; d, cysts. n is 3 to 12 with lower values in higher brood numbers due to death of females with increased culture time. The bars indicate standard error for each measurement. Inset B. Protein extracts from cysts in broods 1–4 were resolved by SDS polyacrylamide gel electrophoresis, blotted to nitrocellulose and probed with antibody to p26 followed by HRP conjugated goat anti-rabbit IgG. Inset C. After stripping the blot was probed with antibody to ArHsp21. Lane 1, brood 1; 2, brood 2; 3, brood 3; 4, brood 4; 5, protein extract from commercially obtained cysts containing p26 and ArHsp21. Proteins reacting with antibodies were visualized by chemiluminescence.
