The Monarthopalpus Buxi Species Population Dynamics in Cluj County (Romania)

Monarthropalpus buxi (  Diptera: Cecidomyiidae) has been described for the first time by Rubsaamen in 1982 (Perju et al., 2001). It is a monophagus species developing on Buxus sempenvirens as its dendrological species, which plays host to Monarthropalpus buxi, and is attacked by its larva. The attack is observed on the leaves of Buxus sempenvirens : the larva feeds on the cellular juice of the leaves, which have a goffering aspect, yellow-rusty in color. The objectives of the research regarded establishing the dynamics of flight curve, circadian rhythm, the effectiveness and efficacy of colored panels. The experiment developed along 24 days, starting with April 30, 2012 until May 24, 2012. Sticky panels have been used, in four different colors, placed above Buxus sempenvirens bushes, in one single row, at three different height levels. The first captures have been observed on May 3, 2012. The maximum of flight curve has been registered on May 11, 2012. The last captures have been registered on May 22, 2012. This year, there have been captured as many as 21,984 adults; the greatest number of individuals have been captured on yellow panels, which means 34.74% of the whole Monarthropalpus buxi  population captured in 2012.
