The effects of linear and cyclic analogs of Locmi-DH, Dippu-DH46 and Dippu-DH31 on appetitive behavior in Locusta migratoria

► We investigated aspects of appetitive behavior of analogs of the diuretic peptides Locmi-DH, Dippu-DH46 and Dippu-DH31. ► The linear fragments and their cyclic analogs of Dippu-DH46 display no significant effects on the latency to feed. ► The linear fragments of Dippu-DH31 and their cyclic analogs, and analogs of Locmi-DH modulate appetitive behavior: they are anorexigenic in reducing the duration of the first meal, and increasing the latency to feed.
