Sinnamaldehit ve Eugenolün Sivrisinek Yumurtlamasını Engelleme ve Larvisidal Etkisi

Dişi Aedes spp. sivrisinek türleri insanlar da dahil olmak üzere çeşitli konakçılardan beslenirler ve dang humması, Zika ve chikungunya virüsleri gibi halk sağlığı açısından önem taşıyan arbovirüslerin vektörlüğünü yapabilmektedir. Bu enfeksiyonlar milyonlarca insanı etkilediğinden dolayı böcek popülasyonlarının izlenmesi ve etkili bir şekilde kontrol edilmesi gerekmektedir. Sinnamaldehit ve eugenol, tarçın, karanfil gibi çeşitli baharatların esansiyel yağlarında bulunan ve farklı biyolojik aktivitelere sahip doğal bileşiklerdir. Cinnamaldehit ve eugenolün Ae. aegypti ve Ae. albopictus'a karşı larva öldürücü ve yumurtlamayı önleyici etkilerini araştırdım. Her iki kimyasal da sivrisinek larvalarını etkili bir şekilde öldürdü ve her iki sivrisinek türü için 50-200 μg/mL konsantrasyonda dişi yumurtlamasını engelledi. Sinnamaldehit ve öjenol gibi larva öldürücü ve yumurtlamayı önleyici bileşikler, sivrisineklerle biyolojik mücadelede oldukça faydalıdır. Larva evreleri öldürerek ve sivrisinekleri insan yerleşimlerinden uzaklaştırarak nüfus sayılarını azaltma potansiyeli sunarlar.

Mosquito Oviposition Deterring and Larvicidal Effect of Cinnamaldehyde and Eugenol

Aedes spp. females feed from various hosts including humans and can vector arboviruses of public health importance like dengue, Zika and chikungunya viruses. These infections affect millions of people so insect populations need to be monitored and effectively controlled. Cinnamaldehyde and eugenol are naturally occurring compounds found in essential oils of various spices like cinnamon, cloves, cassia and have different biological activities. I investigated the larvicidal and oviposition deterrence effects of cinnamaldehyde and eugenol against Ae. aegypti and Ae. albopictus. Both chemicals effectively killed mosquito larvae and deterred female oviposition for both mosquito species at 50-200 μg/mL concentration. Larvicidal and oviposition-deterrent compounds like cinnamaldehyde and eugenol are useful in biological control of mosquitoes. They offer the potential to reduce population numbers by killing immature stages and repelling mosquitoes away from human settlements.
