Sitophilus zeamais (Motsch.) (Coleoptera: Curculionidae) has a global distribution and is one of the most important post-harvest pests maize (Zea mays L.). Some Mexican races could be novel source resistance against S. to improve commercial maize, generating lines, varieties, hybrids with pest.

The bioactivity of turmeric, garlic and curry oil powder were evaluated compared against maize storage pest, Sitophilus zeamais (Motsch.) at 28+20C relative humidity (r.h.) 65+5% in the laboratory. Ten pairs newly emerged weevils introduced separately into each plastics containing 20 g seed treated with plant different concentrations, 0.25%, 0.50% 1.00% v/v similarly dosage levels 0.25 g, 0.50 ...

Behavioral responses of S. zeamais to odours from pulverized wheat, brown rice, sorghum, buckwheat, peanut and cork were compared in a Y-tube-olfactometerbioassay. Results showed that both sexes responded to host volatiles and males were more sensitive than females. The strongest responses to grains of wheat and brown rice were found, and insects reared on these were dramatically heavier than o...
