Abstract:
The phagostimulatory response of the larvae of the gypsy moth, Porthetria dispar, to ethanolic-aqueous extracts of the leaf powder of different host and non-host plants, was assayed in no-choice experiments using the Styropor® method. Quercus robur L. was the most active at all concentrations tested; Picea excelsa Link, was highly active only at 4%; Pyrus malus L. showed an intermediate activity at 4%; and very slight or no feeding occurred with the extracts of Pinus silvestris L., Ilex aquifolium L. and Taxus baccata L. The phagodeterrent effect of the Pinus silvestris and Ilex aquifolium extracts was demonstrated by treating the lamellae with a mixture of each one of them with the highly phagostimulatory extract of Q. robur. The following monoterpenes tested were highly phagodeterrent at 0.2%: α-pinene, β-pinene, 3-carene; camphene was totally deterrent even at 0.05%, whereas limonene was not phagodeterrent even at 0.2%. Among other substances coumarin and lactic acid were active at 0.2%, whereas citric acid, oxalic acid and tannic acid were not phagodeterrent even at 0.2%. © 1975, Springer Science + Business Media B.V..
