INTRODUCTIONInsect behavior can be controlled by a single odor compound or by a blend of a few components in an exact ratio of concentrations. These odor compounds or odor mixtures are called pheromones if used for intraspecific communication. Each of the pheromone components is perceived by a particular type of receptor cell that is specifically tuned to its "key compound" and may respond to single odor molecules by firing single nerve impulses. The entire response range of a receptor cell may cover many decades of stimulus intensities. Each olfactory receptor cell is a bipolar neuron. Its dendrite innervates a specialized cuticular structure, usually a hollow cuticular hair that captures the stimulus molecules. The axon runs directly to the deutocerebrum-the first synaptic relay station of the central nervous system.Chemo-electrical transduction in these organs comprises the processes leading from the adsorption of odor molecules on the cuticular surface via stimulus transport to the generation of receptor potentials and nerve impulses and, eventually, to the inactivation of the stimulus molecules. The interconnections of these processes and their influences on the ultimate impulse response of the receptor cells are largely unknown. This review covers electrophysiological investigations of cellular response charac teristics as well as biophysical and biochemical work, much of which is based on radiolabeled pheromone compounds. These studies employed a few species of insects, mainly of moths with olfactory organs that are relatively large and accessible for experimental work. The olfactory hairs of 121

“…Behavioral (Galun et al, 1969;Koyama and Kurihara, 1971), electrophysiological (Shimada et al, 1972;Villet, 1974), and biochemical (Norris et al, 1971;Singer et al, 1975) evidence supports the theory that sulphydryl groups are involved in chemoreception mechanisms in insects. Sulphydryl reagents such as N-ethylmaleimide, azoester, iodoacetic acid, and p-chloromercuribenzoate can modify the chemoreception phenomenon.…”

The hyperactivity produced in third instar nymphs of Triatoma infestans by their exposure to films of deltamethrin or cis‐permethrin was evaluated. Both pyrethroids produced a significant increase in locomotor activity at 26 and 36°C but not at 16°C. At 26°C, only deltamethrin produced hyperactivity when topically applied on the dorsal side of the nymphs abdomen. However, both pyrethroids produced hyperactivity when topically applied on the head of the nymphs. Hyperactivity was not observed when nymphs were treated with N‐ethylmaleimide (20 μg/insect) before exposure to the pyrethroids. The effect of both insecticides on locomotor activity reversed the inhibitory influence on locomotion elicited by contact with the walls of the experimental arena (thigmotaxis). Arch. Insect Biochem.

“…The 1,4-addition of thiols to quinone (Webb, 1966) has been considered as the reaction mechanism for the anti-feedant effect of quinones for the cockroach and the elm bark beetle, Scolytus multistriutus (Norris, 1970; ., 1 97 1). This suggestion has been substantiated by direct evidence for the energy exchange of quinones with sulfhydryl groups in antenna1 membrane-bound protein of the cockroach as demonstrated by in vitro experiments (Norris et al, , 1971Rozental & Norris, 1973Singer e t al., 1975).…”

“…The second possible mode of action is a reaction of warburganal with the extracellular sensillum liquor bathing the dendrites. Although experimental evidence is still lacking, it has been suggested that this fluid may play a role in stimulus transduction in insect chemoreceptors (Hodgson, 1967;Sturckow, suggests that the enal moiety of warburganal may act as an -SH acceptor, especially in view of the evidence for -SH groups in the chemoreceptor membranes of insects (Norris et aL, , 1971Rozental & Norris, 1973;Frazier & Heitz, 1975;Singer et d., 1975). In order to investigate this possibility, the effects of sulfhydryl-blocking reagents on the functioning of the chemoreceptors were measured on the maxillary sensilla styloconica.…”

Alterations of chemoreceptor function in army worm larvae (Spodoptera exempta) by a plant‐derived sesquiterpenoid and by sulfhydryl reagents

ABSTRACT. Warburganal, a sesquiterpene dialdehyde from Warburgia sp., strongly suppressed the feeding response of Spodoptera exempta larvae to sucrose‐flavoured agar. Its effect on chemoreceptive sensilla of S. exempta was investigated. After a latent period (of up to an hour, depending on concentration), sensilla treated with warburganal produced transient bursting discharges in several receptor cells. Subsequently, receptor responses to sucrose or meso‐inositol were reversibly inhibited. These effects were abolished by mixing warburganal with cysteine or dithiothreitol (though not with other amino acids), and were qualitatively similar to the effects of the sulfhydryl reagents PCMB and NEM. The possible mode of action by which warburganal may act as an –SH acceptor and thereby affect energy transduction in the chemoreceptors is discussed.
