Table 5.
Progeny production (adults per vial ± SE) of Prostephanus truncatus on maize treated with the WG formulation of chlorantraniliprole at five doses (0, 0.01, 0.1, 1 and 10 ppm) under three temperatures (20, 25 and 30 °C) 45 days after the removal of parental adults. Within each column, means followed by the same lowercase letter are not significantly different (in all cases DF = 4, 44, Tukey–Kramer HSD test at 0.05). Within each row, means followed by the same uppercase letter are not significantly different (in all cases DF = 2, 26, Tukey–Kramer HSD test at 0.05). Where no letters exist, no significant differences were recorded.
