1 Digitalis medicines control irregular heart rhythms (called arrhythmias) by slowing the signals that start in the sinoatrial (SA) node. 2  This, in turn, reduces the number of signals that travel through the atrioventricular (AV node). 3  Fewer signals mean fewer arrhythmias.
June beetle (genus Phyllophaga), also called May beetle or June bug, genus of nearly 300 species of beetles belonging to the widely distributed plant-eating subfamily Melolonthinae (family Scarabaeidae, order Coleoptera).
The larva of the May/June beetles, also called May or June bugs, are white c-shade grubs that have a three year life cycle. Noticeable damage to the turf doesnât occur until late in the second year. For the best control, a basic knowledge of life cycles is important.
