“…According to Murdoch (1973) experimental arenas used in functional response experiments are too simple and small. Larvae and adults should be considered as two different entities as larvae are more likely to stay in one patch of prey in the field, while adults may not (Kindlmann & Dixon, 2001;Dostalkova et al, 2002). Patch in this sense means the space that the larva of a predator can reach by walking, usually one or a few adjacent plants, or even only a part of an individual plant.…”

Abstract. Functional responses of immature stages of Propylea quatuordecimpunctata (L.) to varying densities of Aphis fabae Scopoli reared on Vicia faba L. were evaluated under laboratory conditions. All larval stages of the predator were starved for 12 h prior to being placed individually for 24 h in plastic containers with different densities of its prey, A. fabae, on potted V. faba plants. Logistic regression analysis of the proportion of aphids consumed as a function of initial density indicated that all larval instars of P. quatuordecimpunctata exhibited a type II functional response when searching for A. fabae on V. faba plants. Attack rates (0.059, 0.057, 0.065 and 0.064) and handling times (6.18, 2.37, 1.06 and 0.44) for first to fourth instar larvae, respectively, were estimated using Holling's disc equation.

“…Patch in this sense means the space that the larva of a predator can reach by walking, usually one or a few adjacent plants, or even only a part of an individual plant. Thus, the functional response of a larva is determined by the situation encountered in the patch of prey it occupies [ 19 , 20 ].…”

“…Ecology of aphidophagous coccinellids suggests that they display aggregation to their prey [ 16 , 18 ]. Additionally, larvae typically stay within a patch during their life, unlike adults, which are characterized by their ability to make flights [ 19 , 20 ]. As larvae are exposed to each other, frequent encounters between individuals may affect their foraging success.…”

Does Mutual Interference Affect the Feeding Rate of Aphidophagous Coccinellids? A Modeling Perspective

Mutual interference involves direct interactions between individuals of the same species that may alter their foraging success. Larvae of aphidophagous coccinellids typically stay within a patch during their lifetime, displaying remarkable aggregation to their prey. Thus, as larvae are exposed to each other, frequent encounters may affect their foraging success. A study was initiated in order to determine the effect of mutual interference in the coccinellids’ feeding rate. One to four 4th larval instars of the fourteen-spotted ladybird beetle Propylea quatuordecimpunctata were exposed for 6 hours into plastic containers with different densities of the black bean aphid, Aphis fabae, on potted Vicia faba plants. The data were used to fit a purely prey-dependent Holling type II model and its alternatives which account for interference competition and have thus far been underutilized, i.e. the Beddington-DeAngelis, the Crowley-Martin and a modified Hassell-Varley model. The Crowley-Martin mechanistic model appeared to be slightly better among the competing models. The results showed that although the feeding rate became approximately independent of predator density at high prey density, some predator dependence in the coccinellid’s functional response was observed at the low prey—high predator density combination. It appears that at low prey densities, digestion breaks are negligible so that the predators do waste time interfering with each other, whereas at high prey densities time loss during digestion breaks may fully accommodate the cost of interference, so that the time cost may be negligible.

“…In the field, by contrast, predators could leave the immediate area, because they tend to follow those sensory cues that help them detect and localize their habitual prey (or primary prey). The appropriateness of the functional response model parameters and their ability to represent the behaviour of predators and the heterogeneity of their target prey has been questioned (Skalski & Gilliam, ; Dostalkova, Kindlmann & Dixon, ; Rudolf, ). The structure of the model, and the parameters included, must be biologically relevant (Thompson, ; Haila, ).…”

The concept of ecological generalism (or polyphagy) is widely used in ecology to describe and predict aspects of the behaviour of predatory insects, notably with regard to the management of insect pests. The assumptions of ecological generalism have their basis in competition and optimization. We review the historical context and perspectives that led to the development of the concept of ecological generalism as it is applied to diet breadth in predatory insects. We identify how flaws in this concept limit its utility in describing and predicting the behaviour of organisms. We re‐analyse the behavioural expectations of putatively generalist organisms with a focus on the mechanistic aspects of predation; that is, we develop an interpretation based on the adaptations that mediate their responses to particular cues in their environment. This mechanistic analysis emphasizes the need to determine the primary environmental associations of putatively generalist species, and the adaptations that underpin those associations. This approach thus highlights the importance of appropriate matching of predator species to prey species in biological control, based on an understanding of these adaptations and associations. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, ••, ••–••.
