Meta-analysis of the effects of insect pathogens: Implications for plant reproduction

Despite extensive work on both insect disease and plant reproduction, there is little research on the intersection of the two. Insect-infecting pathogens could disrupt the pollination process by affecting pollinator population density or traits. Pathogens may also infect insect herbivores and change herbivory, potentially altering resource allocation to plant reproduction. We conducted a meta-analysis to 1) summarize the literature on the effects of pathogens on insect pollinators and herbivores and 2) quantify the extent to which pathogens affect insect traits, with potential repercussions for plant reproduction. We found 39 articles that fit our criteria for inclusion, extracting 218 measures of insect traits for 21 different insect species exposed to 25 different pathogens. We detected a negative effect of pathogen exposure on insect traits, which varied by host function: pathogens had a significant negative effect on insects that were herbivores or carried multiple functions but not..., Dataset contains 218 comparisons from 39 published articles used in a metaanalysis on how pathogen exposure affects traits of insect pollinators and herbivores. We used the Web of Science database to search for relevant bodies of literature using the following search criteria: Topic [TS]=(lepidoptera* OR bees OR bee OR fly OR butterfl* OR moth OR hymenopter* OR Bombus OR Apis OR bumble* OR aphid* OR caterpillar* OR larva* OR arthropod* OR insect* OR pollinati* OR herbivor* OR orthoptera OR spider* OR hemiptera OR coleoptera OR beetle) AND TS=(trait* OR morpholo* OR proboscis OR foraging OR learn* OR abundance OR sub-lethal OR sublethal) AND Author Keywords [AK]=(disease* OR viru* OR pathogen* OR parasite* OR infect*) AND Title [TI]=(disease* OR viru* OR pathogen* OR parasite* OR infect*). These search criteria yielded 1879 hits from scientific literature published from 1997 to July 9, 2020. A second search was conducted to obtain articles previous to 1997, which yielded 1181 papers (ran..., Data are in a .csv file that can be opened in Excel or imported into statistical software such as R. The last two columns of the dataset (effect size and corresponding sampling variance) were produced by the rma function in the R package metafor.尽管针对昆虫病害与植物生殖的研究已成果丰硕，但二者交叉领域的探索却较为匮乏。侵染昆虫的病原物（pathogen）可通过改变传粉昆虫（insect pollinator）的种群密度或自身性状，干扰植物传粉过程；此外，病原物还可侵染植食性昆虫（insect herbivore）并改变其取食行为，进而可能影响植物对生殖过程的资源分配。本研究开展了一项元分析（meta-analysis），旨在实现两大目标：其一，系统梳理病原物对昆虫传粉者与植食性昆虫的影响相关文献；其二，量化病原物对昆虫性状的影响程度，及其对植物生殖过程的潜在连锁效应。本研究共筛选出符合纳入标准的文献39篇，提取了21种不同昆虫物种在25种不同病原物暴露下的218项昆虫性状测量数据。研究发现，病原物暴露对昆虫性状存在负面影响，且该效应因宿主功能类群而异：病原物对植食性昆虫或兼具多重功能的昆虫具有显著负效应，但…… 本数据集包含来自39篇已发表文献的218组对比数据，聚焦病原物暴露对昆虫传粉者与植食性昆虫性状的影响。 我们通过Web of Science数据库开展文献检索，检索策略如下：主题[TS]=(鳞翅目* OR 蜂 OR 蜜蜂 OR 蝇 OR 蝴蝶* OR 蛾 OR 膜翅目* OR 熊蜂属 OR 蜜蜂属 OR 熊蜂* OR 蚜虫* OR 毛虫* OR 幼虫* OR 节肢动物* OR 昆虫* OR 传粉* OR 植食* OR 直翅目 OR 蜘蛛* OR 半翅目 OR 鞘翅目 OR 甲虫) AND TS=(性状* OR 形态学* OR 喙长 OR 觅食行为 OR 学习* OR 种群丰度 OR 亚致死（sub-lethal）效应) AND 作者关键词[AK]=(病害* OR 病毒* OR 病原物* OR 寄生物* OR 侵染*) AND 标题[TI]=(病害* OR 病毒* OR 病原物* OR 寄生物* OR 侵染*)。上述检索策略共获取1997年至2020年7月9日发表的科研文献1879篇。此外，我们额外开展了一次针对1997年之前文献的检索，共得到1181篇论文（后续筛选过程……） 本数据集以.csv格式存储，可通过Excel打开，或导入R等统计软件进行分析。数据集的最后两列——效应量（effect size）及其对应的抽样方差（sampling variance）——由R包metafor中的rma函数生成。
