Pengaruh Ekstrak Tembakau Sebagai Insektisida Botani Terhadap Perkembangan Lalat Buah (Drosophila Melanogaster)

Edit
Abstract: The important reason is that botanical insecticides didn’t cause environmental damage and not harmful to human health. As we know, tobacco leaf extract is one of many plant extract that use as botanical insecticides.  It  can  kill  fruit  fly  (Drossophyla  melanogaster)  that  suck  domestic  plant.  On  the  other  hand tobacco leaves extract use as wound therapy also. Those effects   are caused of the chemical compound such as  alkaloid,  saponyn,  flavonoid and polyfenol.The  objective  of this study  is to  know  the  impact  of  tobacco leaf  extract  to  development  of  D.  melanogaster.  Beside  that,  we  observe  the  effective  volume  that  causes optimal impact. Therefore we mix four type of tobacco leaf extract on D. melanogaster medium. In this case we apply 10 ml (P1), 20 ml (P2), 30 ml (P3) and 0 (P0). Then we observe the mortality. Further the mortality data is compiling by F analysis and LSD.The result shows that tobacco leaf extract caused negative impact to development  of  fruit  fly  on  all  stage  of  D.  melanogaster  (larvae,  pupae,  adult).  The  most  effective  impact seems  on  P3.  Hopefully,  the  result  of  this  study  might  useful  to  farmer  that  use  botanical  insecticide especially tobacco leaf user. So, user will have more advantages, because it didn’t harmful to human health and environmental.
