Abstract:
Using of pheromones in plant protection has proved in a short period
of time, through numerous researches that were been done on different pest
species, their role in integrated control system. The most important function
from this point of view, it is the possibility through this tool in establishing
the proper moments for applying of treatments.
Through a permanent survey of pest population from orchards,
pheromones could determine an evident reduction of number of chemical
treatments or in some cases their absence.
Pheromone presence in a certain agro ecosystem could also offer
indication on presence of a particular pest, of their frequency of spreading,
offering in these way elements for forecast of appearance in area in which
pest was identified or in adjacent areas.
Methodology of establishing dynamics of pest’s populations with
pheromone traps has permitted introducing of mathematical models for
calculation of generation number and determining economic importance of
each pest generation during one year.
Sexual synthetic pheromones are used in surveying and estimation of
level of microlepidopterous pest from orchards and warning chemical
treatment.
In this paper we present results of researches done during the year
2006 in two apple orchards: Didactic Experimental Field of Orchard
department from University of Agricultural Sciences and Veterinary
Medicine - Bucharest and orchard from Research and Development
Experimental Station - Baneasa.
