In 1998–2001, the cotton aphid (Aphis gossypii Glover, Homoptera, Aphididae) was found to complete its holocycle on Catalpa bignonioides Walt. in Ljubljana (Slovenia). The infested leaves showed curling. The aphid was very damaging by causing the flowers to abort. Many natural enemies (Adalia bipunctata, Chrysoperla carnea, Aphidoletes aphidimyza, Scymnus and Orius species) attack A. gossypii very succcesfully. V letih 1998–2001 smo na cigararju (Catalpa bignonioides Walt.) v Ljubljani (Slovenija) zabeležili bombaževčevo uš (Aphis gossypii Glover, Homoptera, Aphididae), ki se je razvijala holociklično. Napadeni listi so se zvijali. Uš je bila zelo škodljiva in je zavrla cvetenje cigarovca. Plenilci Adalia bipunctata, Chrysoperla carnea, Aphidoletes aphidimyza, Scymnus in Orius vrste so uspešno plenili bombaževčevo uš.
