TLDR
Comparatively study of leaves, heartwood and flowers indicates flowers are having more potent activity than leaves and heartwood, and as the concentration increases, the death time of larvae is decreased.Abstract:
Larvicidal activity of volatiles of different parts of Azadirachta indica was evaluated against Indianameal Moths, Helicoverpa Armigera and Boll Weevil. The growth disrupting properties of volatiles is increased 50 fold depending upon the solvent used for dilution. In contact toxicity test observed that as the concentration increases the death time of larvae is decreased. Comparatively study of leaves, heartwood and flowers indicates flowers are having more potent activity than leaves and heartwood.read more
