In Serbia, Cacopsylla pulchella was determined for the first time on a Judas tree (C. siliquastrum) in the Belgrade area in 2010. In 2010, at several locations in Belgrade, adults and preimaginal stages of jumping plant–lice C. pulchella were collected together with plant material. The collected material was brought to a laboratory for further analysis and rearing. The determination of C. pulchella was based on the keys HODKINSON et WHITE (1979), LOGINOVA (1964) and BURCKHARDT (1999). The examined material is kept in the Entomology collection, Department of Entomology and Agricultural Zoology, Faculty of Agriculture, University of Belgrade, Serbia. Adults of C. pulchella have an olive-drab or brownish green colour (Fig. 1). There are orange stripes on the thorax. The abdomen is dark brown and the intersegmental membranes are orange-red. There are dark brown spots on the forewings. Larval development consists of five stages; in the beginning they have an intense colour and with metamorphosis the colour changes. The fifth instar nymph is light green with a semitransparent wing-pad (Fig. 2). C. pulchella’s feeding and honeydew secretion are harmful. Honeydew can be found on leaves and is a suitable substrate for the development of sooty mold, which causes a reduction in the ability of plants to assimilate and transpire, as well as deterioration of the esthetic value of plants. The attacked leaves become yellow and then necrotize (RAPISARDA et BELCARI, 1997). Besides honeydew, larvae also excrete wax secreta. We have determined that it has one generation per year in Serbia and that it overwinters on other plants.
