Six variétés de cacahuètes (Arachis hypogea L.), à savoir Golden, BARI-2000, Australian, BARD-479, ICG-7326 et 2KCGC20, ont été testées pour voir comment elles résistaient aux attaques d'Odontotermes obesus. On a regardé le pourcentage d'infestation des ouvrières et des soldats, les dégâts causés et l'impact sur le rendement. Les populations moyennes maximales d'ouvrières O. obesus ont été enregistrées sur 2KCGC20 (30,82 ± 2,75 ouvrières/parcelle) et Australian (30,65 ± 2,92 ouvrières/parcelle), suivies par BARI 2000 (19,55 ± 2,51 ouvrières/parcelle), Golden (17,30 ±...

This book describes the synthesis and characterization using proton-NMR, IR, CHNS analyzer, single crystal X-ray diffractometer and quantum chemical studies of novel derivatives of 5-aminotetrazole. The reactions involving acid chlorides were performed in inert atmosphere. The reactions with sulfonyl chlorides gave products with cleaved tetrazole ring structure. In 1H NMR spectrums, aromatic protons were observed at 7.4-7.9 ppm in all derivatives. The density functional theory has been used to investigate the geometric and electronic properties of all the compounds. The B3LYP/6-311G** level...

Six groundnut (Arachis hypogea L.) cultivars i.e. Golden, BARI-2000, Australian, BARD-479, ICG-7326 and 2KCGC20 were evaluated against the attack of Odontotermes obesus in terms of percentage infestation of workers and soldiers, their damage and impact on the yield. The maximum mean populations of O. obesus workers were recorded on 2KCGC20 (30.82 2.75 workers/plot) and Australian (30.65 2.92 workers/plot), followed by BARI 2000 (19.55 2.51 workers/plot), Golden (17.30 2.27 workers/plot) and BARD-479 (16.82 2.06 workers/plot). The minimum mean population of O. obesus workers was found on...
