Opening of cone scales and dropping of seed grains were induced under laboratory conditions. The number of damaged seeds and the type of damage, as well as the total and average number of seeds per cone, were determined on the population and individual levels. The intensity of damage was expressed in percentages. The analyses for determination of the present fungi and the intensity of their attack were conducted by placing the seeds onto a nutritious MEA bed and moist filter paper in Petri dishes. In order to establish the presence of insects, cones with visible damage were collected in the field. These cones were then examined in the laboratory and placed into photoeclectore for further growing. Izvod: Iz mlade šumske kulture Pinus wallichiana osnovane na ilovastom deposolu, sakupljeno je oko 100 poluzrelih šišarica. U laboratorijskim uslovima indukovano je otvaranje njihovih plodnih ljuspi i ispadanje semena. Broj oštećenih semenki i vrsta oštećenja kao i ukupan i prosečan broj semenki po šišarici utvrđeni su na populacionom i individualnom nivou. Intenzitet oštećenja iskazan je u %. Analize za determinaciju prisutnih gljiva kao i intenziteta njihovog napada uradjene su postavljanjem semena na hranljivu MEA podlogu i vlažan filter papir u petri posudama. Radi utvrđivanja prisustva insekata sakupljane su šišarice, sa vidljivim oštećenjima, na terenu. Šišarice su zatim pregledane u laboratoriji i stavljane u fotoeklektori radi daljeg gajenja.
