| description | The behavioral responses of <i>Hypera rumicis</i> L. adults to varying blends of synthetic plant volatiles (SPVs) at various concentrations in lieu of single compounds are reported for the first time. For this study, <i>Rumex confertus</i> plants were treated with two blends of SPVs at different quantities that act as either attractants or repellents to insects. Blend 1 (B1) consisted of five green leaf volatiles (GLVs), namely (<i>Z</i>)-3-hexenal, (<i>E</i>)-2-hexenal, (<i>Z</i>)-3-hexenol, (<i>E</i>)-2-hexenol, and (<i>Z</i>)-3-hexen-1-yl acetate. Blend 2 (B2) contained six plant volatiles, namely (<i>Z</i>)-ocimene, linalool, benzyl acetate, methyl salicylate, β-caryophyllene, and (<i>E</i>)-β-farnesene. Each blend was made available in four different amounts of volatiles, corresponding to each compound being added to 50 µL of hexane in amounts of 1, 5, 25 and 125 ng. The effects of the two blends at the different concentrations on the insects were evaluated using a Y-tube olfactometer. Both sexes of the insects were found to be significantly repelled by the highest volatile levels of B1 and by two levels of B2 (25 and 125 ng). Females were also observed to be repelled using B2 with 5 ng of each volatile. Attraction was observed for both sexes only for B1 at the three lower volatile levels (1, 5 and 25 ng). In additional experiments, using only attractants, unmated females were found to be attracted to males, whereas mated females were only attracted to B1. Both unmated and mated males (previously observed <i>in copula</i>) were attracted only to females. |
