| Abstract;We examined the effect of volatile ingredients in neem oil on oviposition, survivorship and avoidance of the azuki bean weevil Callosobruchus chinensis. Number of eggs laid and developmental survivorship of azuki bean weevil were assessed in air-tight jars filled with volatile ingredients of castor, sesame, sunflower or neem oils. Volatile ingredients of neem oil, as well as other oils, did not have any significant effect on oviposition behavior of adults or survivorship of immatures. Avoidance effect of the neem volatiles against adult azuki bean weevil was estimated using selection experiments. The beetles significantly avoided oil-treated jar compared with control jar, although the avoidance effect was not perfect. These results suggest that the simple use of neem oil as volatiles is not satisfactory for practical pest management. (author abst.) |
