“…A Type II functional response demonstrates that at lower prey densities the consumption rate of prey increases as prey density increases, but eventually levels off and remains constant at high densities (Real 1977 ; Juliano 2020 ). This corresponds to multiple other studies, where a Type II functional response was reported for adult anthocorid species of feeding on psyllid nymphs; including A. minki predating on Psyllopsis repens (Hassanzadeh-Avval et al 2019 ), A. nemoralis on C. pyricola (Emami et al 2014a ), A. minki pistaciae on Agonoscena pistaciae (Kheradmand et al 2017 ) and Orius vicinus on Bactericera cockerelli (Tran et al 2012 ). A Type II functional response may be more optimal than a Type III response (where consumption rates are lower than Type II responses at low prey densities) for anthocorids, as biological control agents are able to detect and attack prey more effectively at low densities (Lopes et al 2009 ).…”

“…Although functional responses can be largely influenced by temperature (Englund et al 2011 ), there are no studies to date on the natural enemy A. nemoralis , using the prey species C. pyri , at multiple temperature regimes. Although, other functional response experiments have occurred on other anthocorid species (Kheradmand et al 2017 ; Hassanzadeh-Avval et al 2019 )d nemoralis (Emami et al 2014b ) at a single temperature (27 °C), allowing comparison.…”

Functional and Behavioral Responses of the Natural Enemy Anthocoris nemoralis to Cacopsylla pyri, at Different Temperatures

et al. 2023

Anthocoris nemoralis is the dominant predator of pear sucker (Cacopsylla pyri) in the UK. Anthocoris nemoralis migrates into orchards in spring or is introduced as a biocontrol agent, reaching peak population levels in July-August, contributing to effective control of summer pear sucker populations. However, due to temperature dependent development and metabolism there are concerns that C. pyri populations or feeding rates may increase due to changing climatic conditions. Thus, how A. nemoralis responds to temperature, impacts its ability as a biocontrol agent. Functional response assays, monitoring attack rate and handling time of A. nemoralis and behavioral assays, using Ethovision tracking software occurred, to assess the impact of temperature on predation. Experiments were conducted at current and future July-August mean temperatures, predicted using RCP4.5 and RCP8.5 (medium and high, representative concentration pathway) emissions scenarios, using 2018 UK Climate Projections (UKCP18). All treatments demonstrated a Type II functional response, with female anthocorids demonstrating shorter handling times and higher attack rates than males. Males showed longer prey handling times at 18 °C compared to 23 °C and more time was spent active at lower temperatures for both sexes. Females did not show significant differences in attack rate or handling time in response to temperature. Overall prey consumption was also not significantly affected by temperature for either sex. This study suggests that anthocorids are likely to remain effective natural enemies under future predicted temperatures, due to non-significant differences in prey consumption.

Pear psylla, Cacopsylla chinensis (Yang & Li) are present as two seasonal morphotypes in pear orchards where they, suck phloem sap, defoliate pear trees, and cause fruit russet. Despite the importance of natural enemies in psyllid control, the interactions between predators and the two seasonal morphotypes of psyllids remain poorly documented. Here we determined the predation efficiencies of the Asian lady beetle, Harmonia axyridis (Pallas) on the two psyllid morphotypes. Predation of H . axyridis on both morphotypes conformed to a Type II functional response: the proportion of consumed psyllids decreased with increasing prey densities. Predation efficiency of H . axyridis against the winterforms increased with temperature when measured from 8 to 25°C. Predation rate on the summerforms was significantly higher than that of the winterforms. This was linked to smaller body size, higher soluble protein level, thinner cuticle, and lower chitin content of summerform psyllids compared to winterform psyllids. Predation capacities of H . axyridis on both morphotypes indicated its potential as a biocontrol agent in psyllids management. Predation efficiency was higher on summerforms, likely due to the difference in body size, exoskeleton fragility, and nutritional value between the two morphotypes. Due to the Type II functional response of H . axyridis to both morphotypes of pear psylla, application of H . axyridis in pear orchards under suitable temperatures could be taken into consideration for suppression of C . chinensis , although further experiments conducted in field conditions are needed to validate our findings.
