Remarks
- Systematics: Rh. falcifer and Ripersiella hibisci were the only macropterous species seen during the study in Hodgson (2012). However, in many other respects Rh. falcifer and R. hibisci differ markedly (character-states on R. hibisci in brackets): (i) antennae almost as long as body (about half as long); (ii) antennal segments of several distinct shapes (antennal segments mainly barrel-shaped); (iii) head behind scapes without a constriction (constricted); (iv) head with a pair of loculate pores (lp absent on head); (v) without an obvious constriction between pro- and mesothorax (constriction distinct); (vi) prosternum possibly absent (present as a thin transverse line with 2 apophyses); (vii) lateral arms of mesofurca almost parallel (diverging strongly); (viii) loculate pores on abdomen present on segments I and VIII and mainly in pleural region (present dorsally on all segments); (ix) penial sheath more or less narrowing gradually (ps with a strong constriction about half-way along length). (Hodgson, 2012)
- Structure: Body of adult female elongate oval, flattened ventrally and convex dorsally, 1.3–2.5 mm long; contents creamy white to pale flesh colour. Body coated with white to bluish grey, cottony-like wax secretion containing egg-laying female and/or eggs. slide-mounted adult female. Body of slide-mounted adult female elongate oval, 1.20–2.35 mm long. Antennae each 5-segmented, moderately slender, about 200– 250 μm long; apical segment with 4 sensory falcate setae and one thinner, finger-like sensory seta. Eyes absent. (Szita 2022a) The specimens collected in Sicily showed circulus absent (∼38% of observed specimens) or numbering one (∼62%) on III abdominal segment. (Mazzeo, et al., 2023)
- Biology: Collected from the roots of host plants in greenhouses.
- Economic Importance: Ripersiella hibisci was detected for the first time in Catania, Sicily, Italy in April 2021 in a nursery in the Province of Catania, Sicily and it was reported by Mazzeo, et al. 2014 and confirmed by EPPO in 2021. Eradication measures were applied and official inspections were conducted regularly. As of December 2021, the pest is considered to be eradicated in all sites (EPPO Reporting Service, 2022). It is interesting to note that major damage to hosts is rare. Only in the case of heavy infestations have symptoms such as slow or poor growth, leaf wilt or discoloration been reported. This lack of economic impact may question the status of R. hibisci as a quarantine pest (Suffert et al. 2024).
