Anti Fungicidal Activity of Secretion from Scent Glands of Heteropteran Bugs

Effect of volatile scent components of heteropteran bugs on the growth of two fungi, Alternaria alternata and Aspergillus clavatus was investigated by Glass cup method. The scent components of n-dodecane showed differential toxicity towards A.alternata and A. clavatus. Undecane significantly reduced the growth of A. alternate where as its effect on A. clavatus was negligible. ntridecane and n-tetradecane exhibited fungicidal activity against both the fungi under study. 1-Hexanol and Propan-1-ol showed lack of fungicidal activity against both the fungi. 1-Butanol exhibited a strong fungicidal activity against both the fungi under study. 2-Butanone a scent component had fungicidal activity but was more inhibitiry than to A. alternata and A. clavatus.
