<i>Chrysomphalus dictyospermi</i> (Morgan) (Hemiptera: Diaspididae): First Record from the Fergana Valley Greenhouses, Uzbekistan

A greenhouse survey conducted in Andijan City, Fergana Valley, Uzbekistan (40.7883463° N, 72.3080521° E; 406 masl) on 7 April 2025 revealed the first record of Chrysomphalus dictyospermi (Morgan) (Hemiptera: Diaspididae). Forty adult female specimens were collected from four host plant species- Phoenix roebelenii, Laurus sp., Citrus limon, and Ficus sp.- all of which were infested. Permanent slide-mounted preparations were examined under polarized light microscopy (40 -400x). Species identification was confirmed following combination of pygidial characters: three pairs of lobes; non-bifurcated, clavate or lanceolate anterior plate apices; five pairs of paraphyses with the second pair not reaching the anal opening; absence of dorsal prepygidial duct clusters; and 7-7 perivulvar pores in the anterior and lateral groups and 3-4 in the posterior group. Among the recorded hosts, Phoenix roebelenii, Laurus sp., and Ficus sp. represent new host plant records for Uzbekistan. The findings highlight the need for enhanced phytosanitary monitoring of imported ornamental plants in the Fergana Valley.
