Evaluation Of The Inhibitory Potentials Of Buchholzia Coriaceae On Sitophilus Zea Mais (Maize Weevils) On Stored Maze Grains

ABSTRACT

Phytochemical composition and inhibitory effects of buchholzia coriaceae on effects of  buchholsia Coriceae as compared to other botanicals (Piper guincese and pepper) on maize weevils (Silophilus zeamcus) were also studied. The maize grains were stored in nylon bag, plastic container and sack bag. The shelf stability of' the maize grains were monitored by evaluating tlìe motility of the maize weevil, moisture content and weight lose of the grains. The result showed that maize stored with piper giuneese in sack bag ranked best followed by maize stored with piper guineese in nylon bag and with maize stored with l3uchholzia coriaceae in plastic, pepper in nylon bag Buc/thoizia coriaceae in sack bag being ranked equal . The result revealed the presence of tannins (O.852mg/lOOmg), alkaloids (0.735mg/bOg). Phytate (0.Ol8mg/lOOg), total phenol (O.ftl3mglbOOg), saponins, steroids and flavonoids (0.013mg/bOg) in the powder. The inhibitory effects of liuchholzia coriaceae was evaluated by storing maize in three different container viz plastic container, nylon bag and sack bag with a temperature of 29°C ±2 and a relative humidity of 65 — 70%.
