Predation Potential of Chilocorus cacti (Coleoptera: Coccinellidae) to the Prickly Pear Cacti Pest Dactylopius opuntiae (Hemiptera: Dactylopiidae)


Functional response of the predator Chilocorus cacti (Linnaeus) (Coleoptera: Coccinellidae) on five densities of Dactylopius opuntiae (Cockerell) (Hemiptera: Dactylopiidae) female adults was assessed under laboratory conditions. The searching efficiency of C. cacti significantly decreased as prey density increased. The logistic regression for the predator… (More)
