“…In so far as individual deterrent receptors may respond to more than one compound (Schoonhoven, 1982), it might be expected that early exposure to an allelochemical, or even perhaps an insecticide, would affect subsequent responsiveness to certain other compounds as well. The finding that early exposure to one species of plant sometimes enhanced the preference for another species (Hovanitz & Chang, 1962) need not imply that exposure to one compound altered the subsequent response to another: instead, it might involve a response to a single compound present at different concentrations in both plant species. Until more is known about the specificity of behavioural induction, it is premature to dismiss the parallel between behavioural induction and enzyme induction on the grounds of specificity differences.…”

Abstract. 1. Changes in the chemosensory responses and physiological host tolerance of phytophagous insects and parasitoids may result in new host associations. This paper considers the origin of those changes in ecological and evolutionary time. 2. The chemical legacy hypothesis postulates that effects of larval chemosensory environment on adult chemosensory responsiveness depend not (or not only) on persistent neural changes (‘memory’), but on traces of chemical cues, inside or outside the insect's body, which influence adult behaviour, perhaps particularly during a ‘sensitive period’ associated with adult emergence or hatching of the egg. 3. Chemical cues bequeathed by earlier stages may affect adults or larvae by reducing peripheral sensitivity. Depending on the form of the dose–response curve, this change could decrease aversion or increase a positive response to a previously deterrent stimulus. 4. Attention is drawn to a possible link between this behavioural induction and the induction of detoxification enzymes. This link might be of practical importance if exposure to host allelochemicals were to influence insects' responses to insecticides, and vice versa. 5. An influence on the chemosensory responsiveness of an individual by chemical cues derived from its parents would be hard to distinguish from a genetic effect. 6. Some testable postulates of the chemical legacy hypothesis are identified.

Imprinting is not a unitary process. Its motor and perceptual aspects can be independently manipulated. This is seen in young ducklings, that will follow a moving surrogate only if previously exposed to it at a particular age (the critical period); but the characteristics of the preferred surrogates are independently (innately?) determined. Similarly, the brief postpartuitive experience essential for the establishment of the maternal care pattern in a goat can be distinguished from the process that leads to discrimination between own and alien young.
