Abstract

Abstract. The predation capacity and prey preferences of Chrysoperla cf. plorabunda (Fitch) on Diaphorina citri Kuwayama, Toxoptera citricida (Kirkaldy); Brevipalpus sp. Baker; and Aleurocanthus woglumi Ashby; economically important pests of citrus, were evaluated under controlled conditions. The study of predation capacity showed that D. citri is the most consumed prey (61.99 ± 4.36), followed by T. citricida (45.23 ± 6.27) and Brevipalpus sp. (24.60 ± 2.82). Chrysoperla cf. plorabunda did not prey on A. woglumi. When combined in the same Petri dish, the Manly's β index indicates a tendency to prefer D. citri over T. citricida and Brevipalpus sp. The results show that C. cf. plorabunda prefers to feed on D. citri over T. citricida, Brevipalpus sp., and A. woglumi. Resumen.

Chrysoperla对柑橘害虫复合体的捕食偏好。Plorabunda(Fitch,1855)(神经翅目:Chrysopidae)
摘要。Chrysoperla CF.Plorabunda(惠誉)对大戟Citri Kuwayama、Citricida Toxoptera(Kirkaldy)的捕食能力和捕食偏好;贝克;阿留罗坎图斯·沃格卢米·阿什比;柑橘的经济重要害虫在受控条件下进行了评估。捕食能力研究表明,D.柑橘是最常用的猎物(61.99±4.36),其次是柑橘类水果(45.23±6.27)和Brevipalpus sp.(24.60±2.82)。Chrysoperla cf.Plorabunda没有捕食A.Woglumi。当组合在同一培养皿中时,Manly的β指数表明倾向于更喜欢D。Citri而不是T。Citricida和Brevipalpus sp。结果表明,C。cf。Plorabunda更喜欢在D上喂养。Citri而不是T。Citricida,Brevipalpus sp.和A。Woglumi。总结。在受控条件下,评估了Plorabunda Chrysoperla CF(惠誉)对Diaphorina citri kuwayama、Citricida toxoptera(Kirkaldy)、Brevipalpus sp.Baker和Aleurocanthus woglumi Ashby(1915年)的捕食能力和捕食偏好,这是柑橘类水果中经济上重要的害虫。捕食能力研究表明,柑橘是消耗量最大的猎物(61.99±4.36),其次是柑橘类水果(45.23±6.27)和短吻鳄(24.60±2.82)。Chrysoperla cf.plorabunda没有以A.woglumi为食。通过在同一个培养皿中组合不同的猎物,Manly的β指数表明倾向于偏爱柑橘D.而不是柑橘T.和Brevipalpus sp.结果表明,C.CF.Plorabunda更喜欢吃柑橘D.而不是柑橘T.柑橘,Brevipalpus sp.和A.Woglumi。
