Table 3 Maximum likelihood estimates from logistic regression of the proportion of P. truncatus larvae and pupae eaten by A. biannulipes as a function of initial prey density

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
