This research investigated the effects of neem oil on mortality, survival and malformations of the non-target stink bug predator, Podisus nigrispinus. Neurotoxic and growth inhibitor insecticides were used to compare the lethal and sublethal effects from neem oil on this predator. Six concentrations of neem oil were topically applied onto nymphs and adults of this predator. The mortality rates ...

Maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) is a polyphagous storage pest in many crops of economic and food security importance. Its management currently relies mainly on synthetic chemical pesticides. However, plant botanicals are known to exhibit insecticidal properties which can be used manage the weevil stored dry sweet potatoes. To study effect neem eucalyptus...

The present work was focused on investigation of effect of solution concentration, contact time and pH variation on ability of the eucalyptus, neem and mango leaves in removing chromium ions form aqueous solution. The dried leaves were washed with deionised water, air-dried and ground using ball mill then sieved. The leaf powder was added to 1M stock metal ion solution made from potassium dichr...

Some extracts from neem seeds/neem seed kernels can give satisfactory to good control of diamondback moth, Plutella xylostella (L.), in cabbage and other crucifers. Water extracts prove most effective, sometimes even at low concentrations as low as 12.5 g of seed kernels per liter of water, provided the raw material contains sufficient azadirachtin. Neem could be developed into products suitabl...

Present studies report the experimental results on the dielectric and attenuation parameters for leaves of two different tree species at X-Band microwave frequency, 10.5 GHz. Leaves of two different tree species viz., Azadirachta indica (Neem) and Acacia indica (Babool) have been used in these measurements. Complex dielectric constants of these tree leaves have been measured by using waveguide ...

Nimonol (1), a tetranortriterpenoid isolated from the leaves of Azadirachta indica A. Juss (Meliaceae), upon photolysis undergoes both Diels-Alder and ene reactions with singlet oxygen at different sites leading to 14,15,20,21-diepoxy-23-nimonolactone (3), along with nimonolide (4), which have been well-characterised. The novelty of the reported reactions lies in hitherto unreported formation o...
