First choice attraction experiments demonstrated that larvae were significantly attracted by uracil at 1 µM (χ2 = 4.03; p = 0.045) and 10 µM (χ2 = 4.17; p = 0.041) concentrations (Fig. 2).
For example, Google helped Nike design its soccer community site, called Joga.com, but it does not appear to have significantly attracted users.
The mixture of urine and mucus of the lumbricid earthworms Aporrectodea giardi and Alollobophora chlorotica significantly attracted H. nitidus as compared to deionized water while fresh earthworm casts were not preferred to calcic mull made of older casts.
C. herbacea was significantly attracted to the synthetic mixture typical of uninfested plants when compared to both air and a synthetic mixture typical of infested plants (Fig. 3).
In experiment 6, male and female D. valens were significantly attracted to male and female H. parallelus hindgut extracts in the Y-tube olfactometer (Fig. 6).
These species revealed a very different behaviour since their larvae were not significantly attracted by plant roots contrary to Coquillettidia larvae which showed a positive response (ANOVA, p<0.0001).
Additionally, using olfactometry under laboratory conditions we have shown that specimens of T. lusitanicus are significantly attracted by acorns during their reproductive period, even preferring this food resource over the dung necessary to lay their eggs for breeding purposes [19].
C. herbacea was significantly attracted to -pulegone when the choice was limited to pure air, infested plants or -menthofuran, whereas the insect preferred undamaged plants when offered with -pulegone.
