Abstract

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.

不同温度下天敌中华花对梨形仙人掌的功能和行为反应。
在英国,nemoralis是梨吸盘(Cacopsylla pyri)的主要捕食者。Nemorali在春季迁移到果园或作为生物防治剂引入,在7-8月达到种群峰值,有助于有效控制夏季梨吸盘种群。然而,由于温度依赖性的发育和代谢,人们担心梨的种群或喂养率可能会因气候条件的变化而增加。因此,A.nemoralis对温度的反应会影响其作为生物控制剂的能力。使用Ethovision跟踪软件进行功能反应分析、监测奈莫拉利斯的攻击率和处理时间以及行为分析,以评估温度对捕食的影响。实验是在当前和未来7月至8月的平均温度下进行的,使用RCP4.5和RCP8.5(中高,代表性浓度途径)排放情景进行预测,使用2018年英国气候预测(UKCP18)。所有的治疗都表现出II型功能反应,雌性花青素的处理时间比雄性更短,攻击率更高。与23°C相比,雄性在18°C下处理猎物的时间更长,两性在较低温度下活动的时间更长。雌性对温度的反应在发病率或处理时间上没有表现出显著差异。对于任何一种性别来说,猎物的总体消耗量也没有受到温度的显著影响。这项研究表明,在未来预测的温度下,由于猎物消耗量的不显著差异,花珊瑚可能仍然是有效的天敌。补充信息:在线版本包含补充材料,请访问10.1007/s10905-023-09836-5。
