摘要：

Newly hatched larvae of the cabbage maggot, Delia radicum (L.), responded to various olfactory stimuli from their host plants and oriented themselves by the concentration gradients of these stimuli. allyl and ethyl isothiocyanate (NCS), characteristic metabolites of host Brassicaceae, elicited positive taxis, but at a higher concentrations were repellent. Benzyl NCS was neutral; only at the highest concentration was it slightly repellent. Phenyl, cyclohexyl, and butyl NCS were repellent in the highest amounts used. Volatile compounds emanating prevailingly from surface parts of plants were both attractive (hexanol, hexanal, cis-3-hexen-1-ol, linalool) and repellent (hexylacetate, cis-3-hexenyl-acetate, benzaldehyde, myrcene, terpinene, alpha-pinene, limonene). While the attractiveness was associated with NCS group and with unsaturated and saturated alcohols and aldehydes with an optimal six-carbon chain length, the repellency was probably caused by a cyclized carbon chain and an acetate group. The activity of a compound was strongly influenced by its concentration.
