Title

EFFECTS OF THREE SPICES POWDERS ON MORTALITY AND PROGENY OF ADULTS OF LESSER GRAIN BORER, RHYZOPERTHA DOMINICA (F.) (COL., BOSTRICHIDAE)

Pages

Abstract

 In this study, an experiment was conducted to investigate the toxicity of three spices POWDERs species, CINNAMON (Cinnamomum aromaticum Ness.), TURMERIC (Curcuma longa L.) and red pepper (Capsicum annuum L.) on adults of lesser grain borer (Rhyzopertha dominica F.). Experiments were done at five different rates 0.5, 0.85, 1.5, 3 and 5 % (wt/wt) with four replications under laboratory conditions (28±1oC, 70±5 % Rh). Twenty adult insects (1-4 day olds) were released in each treatment. The mortality was noted 1, 3, 5, 7 and 14 days after exposure. All insects were removed from all replications after 14 days and the experiments were monitored for the extra 36 days in order to count the number of adult offsprings. The results revealed that the POWDERs had significant insecticidal effects on adults of this insect compare to the control. The toxicities of these POWDERs increased with increase in dosage as well as increase in the period of exposure to the plant materials. Highest mortalities were recorded at the highest dosages and exposure times with TURMERIC, red pepper and CINNAMON, respectively. LD50 values (after 14 days) for TURMERIC, red pepper and CINNAMON were 1.49, 2.10 and 3% of adult weights respectively. All tested materials at the highest dosages reduced significantly F1 progeny emergence of R. dominica. However CINNAMON POWDER at 5 % (wt/wt) prevented reproduction completely (100%). This investigation showed that all three POWDERs spices are suitable in protecting wheat grains against the lesser grain borer.
