The effect of methanolic plant extracts from Solanum nigrum, Acokanthera spectabilis and Heliotropium aegyptiacum were investigated on the larval mortality and development of Culex pipiens L. Also, the effects of the LC50 of the three plant extracts on the larval haemogram were studied. Plant extracts exhibited variable bioactivities. The greatest activity was observed for S. nigrum which showe...

Abstract We present a phylogenetic analysis using plastid (matK, rbcL) and nuclear (nrITS) DNA for diverse Euploca spp. (formerly Heliotropium section Orthostachys) from the worldwide distribution of genus including species encompassing wide physiological morphological diversity genus. Our results indicate that some remarkably complex features arose multiple times in parallel Euploca, attribute...
