Comparative morphology of serotonin‐immunoreactive neurons innervating the central complex in the brain of dicondylian insects

Journal of Comparative Neurology, Volume 531, Issue 14, Page 1482-1508, October 2023., 2023
The central complex is an insect brain area controlling goal‐directed orientation. Comparative analysis of insect species ranging from firebrats to flies reveals two bilateral pairs of serotonin‐immunoreactive neurons innervating the central complex in all neopteran species and two additional pairs of neurons in flies and butterflies.

Secondary Kill Effect of Deltamethrin on Triatoma infestans [PDF]

Journal of Medical Entomology, 2011
Control of the Chagas disease vector, Triatoma infestans, relies on the application of pyrethroid insecticides, especially deltamethrin. We performed laboratory studies to determine whether a T. infestans nymph that comes into contact with a deltamethrin-treated surface horizontally transfers the insecticide to subsequent triatomines.
