Ushbu maqola ignabargli o‘simliklar (Pinus sylvestris, Juniperus communis, Abies alba) ning fitonsidlari fitofag hasharotlar — Lymantria dispar va Sphinx pinastritga qanday ta’sir ko‘rsatishiga bag‘ishlangan. Fitonsidlar suv bug‘i distillatsiyasi bilan ajratilib, GC-MS usulida tarkibiy tahlil qilindi. Repellens va toksik samaralar Petri idishlarida 5 martalik takror bilan sinovdan o‘tkazildi. α-pinen 85 % repellensiya va 60 % o‘lim darajasi bilan eng yuqori faollikni namoyon qildi hamda β-pinen, sabinen va bornil atsetat ham sezilarli himoya xususiyatlariga ega boʻldi. Natijalar ignabarglilar chiqargan terpenoidlar fitofaglarga qarshi kuchli kimyoviy himoya mexanizmi ekanini tasdiqladi. Fitonsidlarga asoslangan biologik parchalanadigan biopestitsidlar ishlab chiqish mintaqaviy agroekotizimlar uchun istiqbolli yo‘nalish sifatida tavsiya etiladi.
