The problem of jumping plant – lice, an important pest on pear, appeared in the middle
of the twentieth century and represents a direct consequence of pear cultivation on large
areas with intensive application of agrotechnical, pomotechnical and chemical protection
measures. Three species of jumping plant – lice are known on pear in Serbia: Cacopsylla pyri,
C. pyrisuga i C. pyricola, among which C. pyri is the most important pest in intensive orchards.
During jumping plant – lice fauna research in Serbia, besides these three species, another
one was determined as well - Cacopsylla bidens.
In the period from 2005 to 2010, the presence and harmfulness of C. bidens were determined
at 56 localities, both in intensive and extensive pear orchards. Besides on cultivated
pears, C. bidens was also determined on wild species of Pyrus genus.
In our conditions, C. bidens overwinters in adult stage on pear. The activation of the
adults that have overwintered occurs at the beginning of March. The extended period of
oviposition provides permanent presence of all developmental stages on plant, so the generations
overlap. It can develop 3 to 4 generations per year. Since this is the first record of
the species in Serbia, this paper describes basic morphological characteristics of the species,
development cycle and distribution. Problem lisnih buva, kao značajnih štetočina kruške, pojavio se polovinom prošlog veka
i predstavlja direktnu posledicu gajenja kruške na velikim površinama uz intenzivnu primenu
agrotehničkih, pomotehničkih i hemijskih mera zaštite. Na području Srbije, na krušci, do
sada su bile poznate tri vrste lisnih buva: Cacopsylla pyri, C. pyrisuga i C. pyricola, od kojih je C.
pyri najznačajnija štetočina u intenzivnim zasadima. Tokom proučavanja faune lisnih buva
Srbije, osim navedene tri utvrđena je još jedna – Cacopsylla bidens.
U periodu od 2005. do 2010. godine na 56 lokaliteta utvrđeno je prisustvo i štetnost C.
bidens, kako u intenzivnim tako i u ekstenzivnim zasadima kruške. Osim na gajenim kruškama,
C. bidens je utvrđena i na divljim vrstama roda Pyrus.
U našim uslovima C. bidens prezimljava u stadijumu imaga na kruški. Aktivacija prezimelih
imaga je početkom marta. Razvučen period ovipozicije obezbeđuje stalno prisustvo
svih razvojnih stadijuma na biljci, tako da se generacije preklapaju. U toku godine može da
razvije 3 do 4 generacije.
S obzirom da se radi o prvom nalazu vrste na teritoriji Srbije, u ovom radu su opisane
osnovne morfološke karakteristike vrste, ciklus razvića i rasprostranjenost.
