“…In general the organization of the female reproductive system of D. citri that we observed agrees with previous descriptions for other psylloid species (e.g. 14,19,20,24,25,88,89 ). Pesson 18 stated that, in psylloids, each ovary has ca.…”

“…However, other reports have found up to 100 ovarioles 88,90 . In D. citri up to 50 ovarioles have been reported 24 which is close to the number we counted, although it varied between ovaries: 40 in the right ovary and 46 in the left ovary. www.nature.com/scientificreports www.nature.com/scientificreports/ In general the calyx (a dilatation of the oviduct for the reception of eggs) is located just after the conjunction of the ovarioles in insects 12,26,91,92 .…”

“…Protuberances of the spermathecal surface, which gave it a rough appearance, correspond to individual secretory cells of the epithelial secretor, as described previously for Trioza alacris 93 and D. citri 24,25 . The spermatheca is not just a storage sac where spermatozoa are stored and/or nourished prior to egg fertilization.…”

“…Whether this also occurs in other insects is not known 26 . D. citri has a pair of tubular, well developed, female accessory glands and, although their structure has been studied previously using electron microscopy, its function has not been elucidated 24 ; currently their role is speculative and requires further research.…”

“…The presence of muscle fibres surrounding the entire spermathecal reservoir has been observed in a number of insect species (see revision by Pascini & Martins 94 ). The presence of bundles of muscle fibrils in the spermathecal sheath of D. citri has also been described using transmission electron microscopy 24 . To pump the sperm into the spermatheca, the musculature of the spermathecal sheath contracts.…”

Huanglongbing (HLB) (citrus greening disease) is one of the most serious bacterial diseases of citrus. it is caused by (1) Candidatus Liberibacter africanus, transmitted by Trioza erytreae and (2) C.L. asiaticus and C.L. americanus, transmitted by Diaphorina citri. As part of a multidisciplinary project on D. citri (www.citrusgreening.org), we made a detailed study, using micro-computed tomography, of the female abdominal terminalia, reproductive system (ovaries, accessory glands, spermatheca, colleterial (= cement) gland, connecting ducts, and ovipositor) and bacteriome, which we present here. new terms and structures are introduced and described, particularly concerning the spermatheca, ovipositor and bacteriome. the quality of images and bacteriome reconstructions are comparable, or clearer, than those previously published using a synchrotron or fluorescence in situ hybridisation (fiSH). this study: reviews knowledge of the female reproductive system and bacteriome organ in D. citri; represents the first detailed morphological study of D. citri to use micro-ct; and extensively revises existing morphological information relevant to psylloids, hemipterans and insects in general. High quality images and supplementary videos represent a significant advance in knowledge of psylloid anatomy and are useful tools for future research and as educational aids.
