“…This independence is reminiscent of the independence between the dorsal vessel and another type of accessory pulsatile organ: the antennal heart. In both mosquitoes and cockroaches, there is no correlation between the contraction rate of the antennal hearts and the dorsal vessel, but different from what we observed for the wing heart, the antennal hearts contract at a significantly slower rate than the dorsal vessel (Hertel et al, 1985;Boppana and Hillyer, 2014;Suggs et al, 2016). Furthermore, some cardioacceleratory peptides, such as CCAP, FMRFamides and proctolin, are known to modulate the contraction dynamics of both the dorsal vessel and the antennal hearts of insects (Cuthbert and Evans, 1989;Predel et al, 2004;Ejaz and Lange, 2008;Hertel et al, 2012;Estevez-Lao et al, 2013;Suggs et al, 2016).…”

“…However, the approach used in the present study diverged from that of previous studies, as we performed our analyses in intact insects, thus maintaining their normal hemocoel pressure and hemolymph components, whereas earlier studies were conducted on dissected specimens that had been immersed in buffer solutions. Furthermore, the basal antennal APO contraction rate of mosquitoes, at approximately 1 Hz, is twice the rate of the antennal APO of dissected cockroaches (Hertel et al, 1985). Crustacean cardioactive peptide is a cyclic amidated nonapeptide that is produced in a broad range of arthropods, including all sequenced insect lineages.…”

“…Furthermore, we show that these neuropeptides also increase the velocity and maximum acceleration of hemolymph in the antennal space. In cockroaches, two types of neuropeptides are known to accelerate the antennal APO contraction rate: proctolin and three FLPs (Hertel et al, 1985(Hertel et al, , 2012Hertel and Penzlin, 1992;Lange et al, 1993;Predel et al, 2004). Proctolin stimulates the contraction of visceral, skeletal and cardiac muscle, and modulates digestion, egg laying, and both sexual and feeding behaviors (Konopinska and Rosinski, 1999;Isaac et al, 2004;Ejaz and Lange, 2008).…”

“…The amplitude of neurally evoked contractions is enhanced by pre-and/or postsynaptic action of the peptide (crustacean skeletal muscle: Schwarz et al, 1980;Bishop et al, 1984;Mercier and Wilkens, 1985;Pasztor and Golas, 1993;insect hyponeural, skeletal, andvisceral muscle: Cook andHolman, 1980, 1985;Evans, 1984;Hertel et al, 1985;Hertel and Penzlin, 1986;Baines et al, 1990;Bauer, 1991; Limulus heart and skeletal muscle: Benson et al, 1981;Watson et al, 1983;Rane et al, 1984;Watson and Hoshi, 1985).…”
