EFFECT OF USING SOME SPICES TO CONTROL THE ADULTS OF RED FLOUR BEETLE Tribolium castaneum (HERBEST) (COLEOPTERA:TENEBRIOIDAE).

Abstract

The study aim to investigate insecticidal and the repellency effects of fourplants :Cinnamomum zeylancium,Zingiber officinale, Myristica fragrans andCoriandrum sativum against the red flour beetles Tribolium castaneum andestimating the percentage of the insecticidal effect for the followingconcentrations 0.0, 0.5 ,1 , 2 , 4 g within seven days , and the percentage of therepellency effect for the same concentrations after 48 hours. The results showedno significant differences in insecticidal and repellent effects of plants powderbetween wheat and barley treatments, However there were highly significantdifferences among concentrations of plant powders of treatments.Also results showed excellence effect of Myristica fragrans powder atconcentration 4% g for repellency effect with value 8.667% while the value for,Zingiber officinale, Coriandrum sativum and Cinnamomum zeylancium powders at the same concentration are 8.167%, 8.000%,7.167% respectively, aswell as the insecticidal effect for concentration 4% g are 1.483%,4.350%,4.350%,5050%for Myristica fragrans, Zingiber officinale, Coriandrumsativum and Cinnamomum zeylancium powder respectively.
