Meiotic chromosomes of the Tingidae species with 2n = 12 + XY studied using conventional staining technique and 18S rDNA FISH. 1–3 Stephanitis caucasica 1, 2 conventional staining: MI (1), AI (2) 3 FISH: MI 4, 5 Stephanitis pyri 4 conventional staining: MI 5 FISH: MI 6, 7 Physatocheila confinis 6 conventional staining: MI/AI transition 7 FISH: early MI 8, 9 Dictyla rotundata 8 conventional staining: MI 9 FISH: MI 10 Dictyla echii FISH: early MI 11 Lasiacantha capucina FISH: prophase I. rDNA FISH signals are indicated by arrows. X and Y chromosomes are indicated by arrowheads. Bar = 10µm.
