Entomocidal effect of a local spicy and fruit peel powders as rice grain protectant against Sitophilus oryzae (L.) Coleoptera: Curculionidae

Akunne C.E, Ononye B.U

Entomocidal potentials of plant powders prepared from a local spicy and fruit peel were evaluated under ambient laboratory conditions of 27±2°C and 75±2% (temperature and relative humidity respectively) against adult rice weevil, Sitophilus oryzae on rice grains. Doses at 2.0/20g, 6.0/20g, 10.0/20g and control were applied for assessments of adult mortality. The Mortality of adult S. oryzae at 24, 48 and 72hrs after treatment were recorded. All concentrations of P. guineense and C. sinensis recorded higher mortality than the control. However, there was significance difference only in the highest concentration (10g) of P. guineense seed powder and the control (P<0.05) in mortality of adult S. oryzae. Also, P. guineensis seed caused significantly higher adult mortality of S. oryzae in rice grains than C. sinensis peel powders. These powders are recommended for the preservation of rice grains.
