“…No specimens of the third species present in pear orchards in Romania, C. pyricola, were identified. Also, the species C. bidens whose spread in Romania is referred to by several authors (Chireceanu, 2007;Shaltiel-Harpaz et al, 2013;Valle et al, 2017;Akbar et al, 2018) has not been reported, even if in the neighbouring country, Serbia, it has been seen in many orchards and localities (Jerinić-Prodanović, 2011). Probably, Cacopsylla bidens (Šulc, 1907) = P. pyricola (Förster) as it appears in Hodkinson (1989).…”

The species of pear sucker, also called pear psylla or pear psyllid, which are destructive insects belonging to the genus Cacopsylla (Hemiptera: Psyllidae) cause substantial damage to pear tree plantations. Two consecutive years of research were conducted on the population structure and biological cycle of psylla in a small, elderly, and unmaintained pear orchard in northern Romania. Of the two identified species (C. pyri L. and C. pyricola Forster), C. pyri dominated the psylla population with a percentage of 77.8-80.1%. Adults of both species emerge from hibernation in the first part of March and produce three generations per year. First-generation adults emerge in the first decade of June, the second generation in the last decade of July, and the third generation in the first decade of September as they enter the hibernation phase. Larvae of the first generation appear in the second half of April, the second generation at the end of June - the beginning of July, and the third generation in the second decade of August. There have been reports of up to 11 adults and 27 larvae per leaf, 9 larvae per petiole, and 14 larvae per fruit. The number of adults captured on yellow sticky traps exposed on the southern side of the tree crown was significantly higher compared to the northern side. Following the intense attack, the well-known cv. ‘Williams’ was heavily affected, pear trees were badly defoliated, blackened, and aged prematurely. The climatic conditions of the two years did not influence the phenology of the pests, but the importance of monitoring psyllids is widely argued, considering that it remains the key to integrated protection programs in pear orchards.

Pear psyllids or pear jumping plant-lice, are the most important pests of this fruit. In Serbia, four species of pear psyllids are harmful to pear. Ali four belong to the genus Cacopsylla: C. pyri (common pear psyllid), C. bidens, C. pyricola (small pear psyllid) and C. pvrisuga (large pear psyllid). The first three belong to the subgenus Hepatopsvlla, have a larger number of generations per year and usually overwinters on the host plant, and C. pvrisuga belongs to the subgenus Thamnopsvlla, has one generation per year and overwinters outside the host plant pear. They can damage the pear directly, through nutrition by sucking out the juices, leading to chlorosis, necrosis and defoliation, and indirectly, by secreting "honeydew". Added to this damage is the role of C. pyri and C. pyricola as vectors of the phytoplasma "Candidatus Phytoplasma pyri", the cause of the disease called "pear decline".
