The lacewings (Neuroptera: Chrysopidae) are predators of several economically important pests in agriculture and they are naturally present in the citrus orchards in Brazil. However, their abundance and diversity needed to be determined in order to identify their role in the management of Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Liviidae), which is an economically important pest and vector of huanglongbing. Our goals were to identify lacewing species and their abundance in the organic and conventional management programs against ACP in the citrus crops and determine the biological parameters of the predominant species on ACP. The lacewings were monitored in three municipalities of São Paulo state, Brazil, from November 2015 to June 2017. We identified Ceraeochrysa cincta (Schneider), Ceraeochrysa cubana (Hagen), Ceraeochrysa paraguaria (Navás), Chrysoperla externa (Hagen), and Chrysoperla defreitasi Brooks species and those were equally abundant between conventional and organic management psyllid management programs. Ceraeochrysa cincta was predominant in both systems, representing more than 60% of all the specimens. They developed and reproduced successfully on the diet of D. citri nymphs when compared against Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) eggs. The abundance of these multiple species and predominance and development of C. cincta on D. citri suggest their potential use for biological control of D. citri in organic and conventional psyllid management programs.

草wing（Neuroptera：Chrysopidae）是农业中几种重要经济害虫的捕食者，它们自然存在于巴西的柑橘园中。然而，需要确定它们的丰度和多样性，以鉴定其在亚洲柑桔木虱（Aidophina citri Kuwayama（半翅目：:科））的管理中的作用，这是黄龙病的一种重要经济害虫和媒介。我们的目标是在柑桔类作物中针对ACP的有机和常规管理计划中确定lace虫物种及其丰富度，并确定ACP上主要物种的生物学参数。2015年11月至2017年6月，在巴西圣保罗州的三个城市中对草lace进行了监测。我们确定了Ceraeochrysa cincta（Schneider），古巴Ceraeochrysa（Hagen），Ceraeochrysa paraguaria（Navás），Chrysoperla externa（Hagen）和Chrysoperla defreitasi Brooks物种，这些物种在常规和有机管理木虱管理计划中同样丰富。在这两个系统中，Ceraeochrysa cincta占主导地位，占所有标本的60％以上。与库氏埃弗氏菌卵（鳞翅目：Pyralidae）卵相比，它们在柠檬果蝇（D. citri）若虫的饮食中成功发育和繁殖。这些多品种和优势及开发的丰度C. cincta对亚洲柑橘木虱提示它们在有机和常规木虱管理计划中潜在地用于柑橘中D.citri的生物防治。
