The Role of Eicosanoids in Nodulation Reaction Against Entomopathogenic Fungi in Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) Larvae
Abstract
The study carried out the role of eicosanoids on nodulation reactions in Spodoptera littoralis larvae, against two fungal isolates (Beauveria bassiana 6646 and Metarhizium anisopliae 3293). When the larvae were infected with Beauveria bassiana 6646 and Metarhizium anisopliae 3293, the insects showed a nodulation reaction to this infection. Injecting eicosanoid biosynthesis inhibitors just before the S. littoralis larvae were infected with fungal isolates reduced the nodulation response to fungal isolates. Specific applications, including inhibitors of enzymes in eicosanoid biosynthesis; “dexamethasone (a phospholipase A2 inhibitor), indomethacin, naproxen, ibuprofen (cyclooxygenase inhibitors), esculetin (a lipoxygenase inhibitor) and phenidone (both cyclooxygenase / lipoxygenase inhibitor) reduced” formation of nodules in S. littoralis against fungal infection. These findings support the hypothesis that eicosanoids are involved in nodulation reactions against fungal infections in larvae of S. littoralis.

Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) Larvalarında Entomopatojenik Funguslara Karşı Nodülasyon Reaksiyonunda Eikosanoidlerin Rolü
Abstract
Çalışma, iki mantar fungus (Beauveria bassiana 6646 ve Metarhizium anisopliae 3293) karşı, Spodoptera littoralis larvalarındaki nodülasyon reaksiyonları üzerinde eikosanoidlerin rolünü test etmiştir. Larvalar Beauveria bassiana 6646 ve Metarhizium anisopliae 3293 ile enfekte edildiğinde, böcekler bu enfeksiyona karşı nodülasyon reaksiyonu göstermiştir. S. littoralis larvalarına fungus izolatları ile enfekte edilmeden hemen önce eikosanoid biyosentez inhibitörlerinin enjekte edilmesi, fungus izolatlarına nodülasyon tepkisini azaltmıştır. Deksametazon (bir fosfolipaz A2 inhibitörü), indometasin, naproksen, ibuprofen (siklooksijenaz inhibitörleri), esculetin (bir lipooksijenaz inhibitörü) ve fenidon (her ikisi de siklooksijenaz/lipooksijenaz inhibitörü) dahil olmak üzere eikosanoid biyosentezindeki enzim inhibitörleri ile yapılan spesifik uygulamalar. S. littoralis'te fungal enfeksiyonuna karşı nodül oluşumunun azalmasına sebep olmuştur. Bu bulgular, eikosanoidlerin S. littoralis larvalarındaki fungal enfeksiyonlarına karşı nodülasyon reaksiyonlarına dahil olduğu hipotezini desteklemektedir.
