Pollinator insects have a very important role in terrestrial ecosystems. Sustainability of plant communities

and ecosystem stability depend on the relationship between pollinators and plants. Pollinator insects are a key

component of global biodiversity. However, insecticide application in agro-systems, destruction of natural habitats

by changing of landscape and land use are cause of a reduction or even extinction of pollinator population. As a

result of these, it has emerged ‘global pollination crisis’. According to current data, world biodiversity is declining

steadily. The main causes of the pollination crisis are evaluated in this review.

Polinatör Böcekler ve Küresel Tozlaşma Krizi

Öz

Polinatör böcekler karasal ekosistemlerde son derece önemli görevler üstlenirler. Bitki komünitelerinin

devamlılığı ve ekosistem dengesinin korunması, bitkiler ve tozlaşmalarını sağlayan polinatör böcekler arasındaki

ilişkinin sürdürülebilmesine bağlıdır. Bu bakımdan polinatör böcekler, küresel biyoçeşitliliğin anahtar bileşenidir.

Ancak, tarım alanlarında insektisit uygulamaları, arazi kullanımının ve peyzajın değişmesi ile doğal habitatların

tahrip olması polinatör popülasyonunun azalmasına hatta yok olmasına sebep olmaktadır. Bunların sonucu olarak

son yıllarda ciddi bir ‘küresel tozlaşma krizi’ ortaya çıkabilir. Güncel verilere göre dünya biyoçeşitliliği giderek

azalmaktadır. Bu derlemede, tozlaşma krizinin ana sebepleri ele alınmıştır.
