Damages produced by the pest insects can be very big, thus care must be taken about some aspects concerning the incidence in samples, dynamics and evolution of one of the most important insect pests of the flowers, such as Thysanoptera. Due to the relatively high incidence of Thrips tabaci in the samples collected from the experimental field of marigold, the species presented a real economic importance. To obtain a high production and superior quality it was necessary to choose the best moment for treatments by applying in function of population dynamics of those pests. In case of population dynamics of adults and larva of Thrips tabaci from the crop of Calendula officinalis L., the maximal values in all local populations taken in study were in increase in the second decade of June, and reached the maximum level in the third decade of June. It was followed by an obvious decrease in July - their number started to decrease to the end of the collecting period, until the second decade of August, thanks to the end of vegetation period of the flowers. In function of population dynamics, the best time for applying treatments in the crop flowers was during the period 15.06.2011- 26.06.2011.
