INDUCTION OF SPECIFIC FOOD PREFERENCE IN LEPIDOPTEROUS LARVAE 1
In larvae fed on artificial diet preference to a given host plant can be induced even by a one‐day feeding on it, and it is supposed that the information serving as a basis for the induced feeding habit is stored in the central nervous system.
A technique for electrophysiologically recording from chemosensory organs of intact caterpillars
Details of the new technique using a large caterpillar, Manduca sexta, are presented and it is attempted to show that it can be immobilized for hours without impairment, that its chemoreceptive sensilla remain functional during this period of immobilization, and that it recovers for subsequent experiments.
Deterrence coding by a larval Manduca chemosensory neurone mediating rejection of a non‐host plant, Canna generalis L.
Abstract. The physiological basis of phagodeterrence was studied electrophy‐siologically and behaviourally in the phytophagous caterpillars Manduca sexta and Manduca quinquemaculata. The model…
Aspects of Light Production by Photobacterium fischeri
Results suggest that the inhibitor may be binding directly to the luciferase molecules, and the mechanism of action and the chemical properties of the inhibitor are carried out.
Food discrimination and induction of preference for artificial diets in the tobacco hornworm, Manduca sexta
The data suggest that food discrimination depends on the perception of a complex chemical message comprised of both polar and non‐polar compounds, with the latter being of somewhat greater importance.
Comparative studies of firefly pacemakers.
- F. Hanson
- BiologyFederation proceedings
Comparative studies of the phase angle differences between the animal's flash and the flash of a controlled light source suggest at least two different mechanisms of attaining synchrony: 1) by cycle-to-cycle phase shifting of a stable oscillator; 2) by changing the underlying period of a variable oscillator.
Control of flashing in fireflies
A model of the endogenous timing cycle is devised which fits the empirical data and achieves entrainment by a single mechanism involving phase advance or delay rather than change in actual rate of endogenous timing.
Differentiation of roles of chemosensory organs in food discrimination among host and non‐host plants by larvae of the tobacco hornworm, Manduca sexta
The contributions of olfactory and gustatory organs in food plant discrimination were examined in larvae of Manduca sexta (Johan.) (Lepidoptera, Sphingidae) using a two‐choice disc bioassay.
CONTROL OF FLASHING IN FIREFLIES. III. PERIPHERAL EXCITATION
The quick flash resembles the slow in contour, in apparently being produced by the same tissue, in showing a strength-duration effect for threshold and in showing facilitation, summation, adaptation, fatigue and other typical neuroeffector responses.
