To develop effective and targeted biocontrol tactics for the brown marmorated stink bug, in crop habitats, a good understanding is essential of the abundance and diversity of its parasitoids in different crop habitats in its native range. To obtain information on the egg parasitoid communities of in kiwifruit, surveys using sentinel egg masses were conducted in 2018 and 2019. These assessed the species composition of egg parasitoids of in green-fleshed 'Hayward' kiwifruit orchards, and quantified their season-long abundances in orchards under two different management systems. Parasitism was observed from June to August 2018 (mean parasitism: 48%) and from May to August 2019 (mean parasitism: 29%) across the experimental orchards. In total, five different parasitoid species were found across the two surveys seasons in the kiwifruit orchards, , , , , and sp., where and were the predominant species. Monthly abundance data had a unimodal distribution in 2018, peaking in July. There were two peaks (May-June and August) in the 2019 season. Overall, was significantly more abundant in the organic orchard than the conventionally managed orchard only in 2018, and its monthly abundance differed significantly in the two orchards in the two survey seasons. Results and their implications for future classical biological control for in kiwifruit are discussed.
为了制定针对褐边绿刺蝽的有效且有针对性的生物防治策略，在作物生境中，深入了解其原生范围内不同作物生境中寄生蜂的数量和多样性至关重要。为了获取猕猴桃中卵寄生蜂群落的信息，在2018年和2019年使用哨兵卵块进行了调查。这些调查评估了绿肉‘海沃德’猕猴桃果园中卵寄生蜂的物种组成，并量化了它们在两种不同管理系统下果园中的全年数量。在整个试验果园中，2018年6月至8月观察到寄生现象（平均寄生率：48%），2019年5月至8月观察到寄生现象（平均寄生率：29%）。在猕猴桃果园的两个调查季节中，总共发现了五种不同的寄生蜂物种，即[物种1]、[物种2]、[物种3]、[物种4]和[物种5]属，其中[物种1]和[物种2]是优势物种。2018年月度[物种名称]数量数据呈单峰分布，7月达到峰值。2019年季节有两个峰值（5月至6月和8月）。总体而言，仅在2018年，[物种名称]在有机果园中的数量显著多于传统管理果园，并且在两个调查季节中，其在两个果园中的月度数量存在显著差异。讨论了这些结果及其对未来猕猴桃中[物种名称]经典生物防治的影响。
