Comparative Analysis of Organic Compounds in Larval Habitats of Culex pipiens and Culiseta longiareolata

Öz

Mosquitoes are vector organisms with a wide global distribution and significant ecological and public health importance. Culex pipiens and Culiseta longiareolata are two widely distributed mosquito species that have adapted to diverse aquatic habitats and complete their larval development in a range of natural and anthropogenic water bodies. The ecological characteristics of larval habitats play a central role in shaping species biology, population dynamics, and vector potential. Culex pipiens is generally associated with stagnant waters rich in organic matter, including polluted and eutrophic environments such as sewage systems and wastewater, whereas Culiseta longiareolata is more frequently reported from temporary water bodies and relatively clean or semi-clean aquatic habitats. Nevertheless, accumulating evidence indicates that both species exhibit considerable ecological plasticity, allowing them to persist under varying physicochemical and biological conditions. This review synthesizes current knowledge on the larval habitat preferences of C. pipiens and C. longiareolata, with particular emphasis on physicochemical parameters, biotic interactions, and tolerance to environmental stressors. In addition, recent advances in habitat characterization approaches, including the application of molecular and chemical profiling techniques, are discussed. Despite growing interest in this field, the relationships between the chemical composition of larval habitats and species-specific behavioral responses remain insufficiently explored. A clearer understanding of these mechanisms is essential for the development of effective and environmentally sound vector control strategies.

Culex pipiens ve Culiseta longiareolata Larval Habitat Sularının Kimyasal İçeriklerinin Karşılaştırılması

Öz

Sivrisinekler, dünya genelinde geniş bir yayılım gösteren ve ekolojik açıdan büyük öneme sahip vektör organizmalardır. Bu derlemede ele alınan Culex pipiens ve Culiseta longiareolata türleri, farklı habitat özelliklerine uyum sağlamış ve larval gelişimlerini sucul habitatlarda sürdüren iki önemli sivrisinek türüdür. Sivrisineklerin larval dönemlerini geçirdikleri habitatlar; türlerin biyolojisi, popülasyon dinamikleri ve potansiyel vektörlük rollerini şekillendiren temel ekolojik faktörlerdendir. Culex pipiens genellikle yüksek organik madde içeriğine sahip, durgun suları (kanalizasyon sistemleri, atık sular) tercih ederken; Culiseta longiareolata çoğunlukla geçici su birikintilerinde, temiz veya yarı temiz ortamlarda (yağmur havuzları, kaya oyukları) üremeyi tercih etmektedir. Ancak son yıllarda yapılan çalışmalar, bu türlerin sanılanın aksine katı ekolojik sınırlara sahip olmadığını ve çevresel strese karşı yüksek bir ekolojik plastisite geliştirdiklerini göstermektedir. Bu çalışmada, halk sağlığı açısından kritik öneme sahip bu iki türün larval habitat tercihleri; fizikokimyasal parametreler, biyotik etkileşimler (predasyon ve rekabet) ve kimyasal kirlilik toleransı açısından kapsamlı bir şekilde incelenmiştir. Ayrıca, habitat karakterizasyonunda geleneksel yöntemlerin ötesine geçerek, suyun moleküler profilinin (organik bileşikler) belirlenmesinde Gaz Kromatografisi-Kütle Spektrometrisi (GC-MS) gibi analitik tekniklerin önemi tartışılmıştır. Bununla birlikte, larval habitatların kimyasal bileşenleri ile türlerin davranışsal tercihleri arasındaki ilişkilerin hâlen sınırlı sayıda çalışma ile ele alındığı görülmektedir. Derlenen veriler, türlerin habitat seçim mekanizmalarının anlaşılmasının, vektör kontrol stratejilerinin geliştirilmesindeki kritik rolünü ortaya koymaktadır.
