“…It could be interpreted as a blockage of inhibitory neurons. 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.

“…These authors showed that treatment with the sulphidryl reagent N-ethyl maleimide, that blocks chemoreception, produced a significant decrease in repellency. However these results were not enough to determine whether the repellent is detected by contact or olfactory (or both) chemoreceptors, since the sulphidryl reagents block either contact or olfactory chemoreception (Koyama and Kurihara, 1971;Singer et al, 1975;Villet, 1974). We asked if contact chemoreceptors present in Rhodnius antennae could also participate in repellent detection when insects are in contact with the DEET-treated surface.…”

“…N‐ethylmaleimide, a sulphydryl reagent, is one. Its ability to interfere with chemoreception in insects, particularly olfaction, has been demonstrated in behavioural ( Koyama & Kurihara 1971), biochemical ( Singer et al . 1975 ) and electrophysiological ( Villet 1974) assays.…”

“…In order to analyse the role of chemoreceptors in the repellency elicited by deet, the sulphydryl reagent N‐ethylmaleimide (N‐em) known to blockade insect chemoreception ( Koyama & Kurihara 1971; Villet 1974; Singer et al . 1975 ) was topically applied dorsally on the thorax of nymphs using a microsyringe with dispenser (Hamilton, Reno, NE, U.S.A.).…”

The repellency of N,N-diethyl-3-methylbenzamide (deet) to Triatoma infestans (Klug) (Hemiptera: Reduviidae) was evaluated using third-instar nymphs and a video tracking technique. Three experimental designs were used: (a) the test arena floor was divided into two halves, only one of which was treated with deet; (b) the arena floor was divided into an inner circle and an outer ring, only the latter treated with deet; (c) half of the test arena was covered by a filter paper roof treated with deet (out of reach of the nymphs). In all three types of experiment, a repellent effect was demonstrated proportional to the dose of deet. When a host (pigeon) was shielded by deet-treated gauze, the rate of blood-feeding by the nymphs was inhibited. Topical pre-treatment of the nymphs with N-ethylmaleimide, to block chemoreception, inhibited the repellency.
