Table 5 Numerical response of predator A. biannulipes feeding on P. truncatus larvae at various densities

From: Population dynamics of the predator Alloeocranum biannulipes Montrouzier and Signoret (Hemiptera: Reduviidae) feeding on the larger grain borer, Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), infesting cassava chips

ANOVA	df = 35 F = 52.414 P < 0.000	df = 35 F = 0.432 P > 0.05	df = 35 F = 2.084 P > 0.05	df = 35 F = 2.576 P > 0.05

In each column, mean values followed by different letters are significantly different (P < 0.05)
