BACKGROUND Tracking predator–prey interactions using automated image recording systems provides insights into novel patterns and mechanisms of predator–prey dynamics, thus these systems have the potential to evaluate biological control agents effectively. Using an automated video tracking system, we aimed to quantify the behavioural patterns of a generalist predator Harmonia axyridis in response to changing prey density. The effect of intraspecific interactions on foraging efficiency was evaluated. In addition, functional response parameters were compared between the observations and model predictions. RESULTS The associated behavioural component of prey consumption by H. axyridis was modified by prey density, especially for dual predator trials. Both individual and paired H. axyridis exhibited type II functional responses and a consistent cycle of behaviour. Interestingly, intra‐specific interference did not affect overall prey consumption. Divergence between estimated and calculated functional response parameters was observed, which might due to the difficulty of separating foraging and non‐foraging activity. CONCLUSIONS Interference interactions between H. axyridis conspecifics might alter their foraging patterns; however, the outcome of prey consumption was not affected by this behaviour. In conclusion, automated video tracking systems may be used to expose the detailed foraging behaviour of predators and could be used to evaluate a wide range of natural enemies. © 2019 Society of Chemical Industry

“…As a consequence, the majority of empirical studies on predator–prey models have been conducted under laboratory conditions (e.g. Desurmont & Weston, 2008; Mahdian et al , 2008; Seko & Miura, 2008), where many aspects of the predator–prey interaction can be controlled. However, the results of such studies have often proved difficult to translate to field populations (Sih et al , 1998; Lester & Harmsen, 2002) due, among other factors, to the unavoidable simplifications of laboratory experiments.…”

Abstract. 1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely absent.2. In the present field study, the total response of the generalist invertebrate predator community to experimentally established pupal densities of the closely related autumnal (Epirrita autumnata) and winter moths (Operophtera brumata) was analysed.3. Due to the high amount of variation in the dataset, the exact shape of the response curve could not be convincingly estimated. Nevertheless, two important conclusions can be drawn from the analyses.4. Firstly, the natural invertebrate predator community seems to become saturated at rather low densities of both autumnal and winter moth pupae. Secondly, the predator community seems to become saturated at much lower densities of autumnal than of winter moth pupae.5. Furthermore, pupal mass was significantly negatively correlated with invertebrate predation probability in autumnal moth pupae.6. These results indicate that differences in the predator assemblage being able to consume pupae of the two moth species, as well as different handling times, could be responsible for the substantially higher predation rates in winter than in autumnal moth pupae.7. As a consequence, the population dynamics of autumnal moths might be less affected by generalist invertebrate predators than those of winter moths, as autumnal moths seem able to escape from the regulating influence of generalist predators at much lower population densities than winter moths.

“…Type III functional response are occasionally observed for some invertebrate predators (Hassell et al., ; Schenk & Bacher, ), especially under field conditions where particular factors can affect their behavior (Montoya et al., ). However, type II functional response is the most common response in invertebrate natural enemies (Fernández‐Arhex & Corley, ; Matadha et al., ; Monzó et al., ) including aphidophagous coccinellids (Koch, ; Seko & Miura, ; Xue et al., ; Farhadi et al., ; Jalali et al., ; Aqueel & Leather, ; Papanikolaou et al., ). For type II functional response, the predator–prey dynamics is unstable because the fraction of prey killed would decrease with the increase of prey density (Hassell, ; Abrams, ).…”

Harmonia axyridis (Pallas) and Propylea japonica (Thunberg) (both Coleoptera: Coccinellidae) are two common aphidophagous predators that overlap in their natural niche; therefore, interactions between these two predator species could affect their overall prey consumption. The consequences of intraguild interactions on the foraging efficiency of the two coccinellid species were investigated by evaluating the functional responses of single beetles and intra‐ and interspecific combinations to densities of the spirea aphid, Aphis citricola van der Goot (Hemiptera: Aphididae), on apple seedlings, during 2 and 12 h under laboratory conditions. A type II functional response was observed in all the bioassays. Solitary H. axyridis consumed significantly more aphids than single P. japonica in both exposure periods. However, at intermediate prey densities the prey consumption of P. japonica was slightly greater than that of H. axyridis. The 95% confidence intervals of the functional response curves of conspecific and heterospecific pairs overlapped at 2 h. In contrast, conspecific pairs of H. axyridis showed a higher functional response curve at 12 h compared to a combination of H. axyridis and P. japonica. Prey's predation risk reduction was only detected for paired H. axyridis and mixed predators compared to their estimated functional responses at the 2‐h foraging period. By comparing functional responses between intraguild predatory lady beetle combinations, we could further predict the potential ecosystem service provided by these natural enemies.
