Abstract

The eco-morphological adaptation of the pupal stages of some Polish Thripidae has been investigated in the laboratory. The propupa and pupa of species developing in grass inflorescences or in narrow cravices of leaf sheaths (Chirothrips pallidicornis, Iridothrips iridis) are characterized by shorter setae and smaller abdominal thorns than species developing on leaf blades or in flowers (Frankliniella tenuicornis, F. intonsa, Pezothrips dianthi, Thrips fulvipes, T. fuscipennis, T. menyanthidis, T. physapus, T roepkei, T. sambuci, T. simplex). Species feeding on monocots pupate and molt on their hosts as do the folicolous species feeding on dicots. In contrast, the floricolous ones feeding on dicots drop off the hosts and develop in the soil. Variation in the shape of the abdominal apical projection of the pupal stages of the female are described.
