The monitoring of the species with harmful
potential is very important because it allows to
acknowledge the level of development of the
germs aand of the pests and the understanding of
biological cycles of the pests allows the proper
intervention in the most adequate moments for
stopping or limiting the destructive effects of
pests on the agricultural crops.
Studiile şi practica referitoare la dăunătorii
culturilor agricole şi combaterea acestora au
demonstrat că dăunătorii autohtoni, care sunt
foarte bine adaptaţi condiţiilor climatice nu pot fi
eradicaţi şi de aceea controlul dăunătorilor se
referă în mod deosebit la monitorizarea acestora
şi menţinerea lor sub limita pragului economic de
dăunare.
The study and the experience regarding the
pests of agricultural crops and their control have
proved that the local pests, which are very well
adapted to climate conditions can’t be eradicated
and this is the reason why the pests’ control refers
especially to their monitoring and maintaining the
number of individuals under the limit of
economical threshold of injury. The study on the
invertebrates’ communities in some biological
cultures in SCDL Bacau, performed during a
period of four months, June – September 2007,
has aimed at monitoring the pests and the useful
fauna for applying some preventive and curative
measures of limiting the pests’ attacks.
In the four studied cultures there were
identified 35 taxons of invertebrates belonging to
different systematic groups (2242 individuals). In
the biological agriculture, preventive and curative
measures of limiting the pests’ attacks are
adopted, especially in the case of vegetable
plants, measures that, besides the improvement of
the agricultural work, seek to identify the useful
fauna (animal feeders) and to protect and
encourage their breeding.
Within the study we performed, the
greatest percentage of useful fauna registered
during the whole period of research was in the
celery culture, followed by the ones measured in
the dill, parsley and violet tomatoes cultures. |
