Abstrakt
In Estonia frit fly (Oscinella frit L.) is a common pest of cereals and grasses. The greatest
damage is caused by larvae feeding at the plant growth point, while control options
against them are limited. Although contact insecticides can be used against ovipositing
adults, their effective use requires reliable monitoring methods, which are currently
lacking in Estonia. The results of this experiment showed that throughout the study
period, the highest number of frit fly larvae occurred in fields where winter wheat was
grown as the test crop. Larval abundance of frit fly in winter wheat was nearly twice as
high as in winter barley. This suggests that, among the crops studied, winter wheat provided
the most favourable conditions for frit fly development. Although winter barley
is attractive for oviposition and shoot damage was considerable, larval development in
winter barley may be significantly slower, which likely reduces their survival rates. As
this was a pilot study, no definitive conclusions can be drawn from the present results.
Future studies should also investigate the occurrence and abundance of frit flies in other
winter cereals, such as rye and winter triticale, as well as in grass species.
