In the current study, a series of cationic α-helical peptides of 20 a.a. were designed and synthesized based on four structural parameters, including charge, polar angle, hydrophobicity, and hydrophobic moment. Several methods were performed to describe the influence of these parameters on the antimicrobial and hemolytic activity, and on the permeabilizing effect on model membranes. The potential of these parameters to increase the antibacterial activity and to improve the prokaryotic selectivity is assessed.

Mushroom bodies and antennal lobes in Oxycetonia jucunda were conspicuous. Calyces and lobes of the mushroom bodies.were much developed. In contrast, calyces of Ambrostoma quadriimpressum and Henosepilachna vigintioctomaculata were extremely undeveloped. However, the postretinal fibres and circumpharyngeal nerves of Ambrostoma quadriimpressum were highly developed. In the three beetles, 5-HT immunoreactivity was present in all neuropils of the brain and the suboesophageal ganglion. The pattern of 5-HT immunoreactivity and the localization of immunoreactive somata which often clustered into groups were similar among these beetles, while the immunoreactivity intensity was distinct, especially in the lamina.
