| Abstract: | The research of harmful insects for pine forest was achieved in two distinct areas: the hilly area of the village Pietroşani (Argeş) and the mountain area Clăbucet during the years 2008 and 2009. Using various methods of study, in the mentioned areas, we identified the following species of insects: Ips typographus, Hilastes ater, Pytiogenes chalcographus, Hylurgops palliatus. Among these the first three had numeric explosion causing major damage to the forests. By processing the field data we determined: the intensity of the attack, the insect population density, the frequency of the attacked trees, the propagation coefficient, and the abundance. Knowing all these parameters it was possible to develop short-term forecasts useful in forestry. |
