. Long tailed mealybug (Pseudococcus longispinus Targ.) is an important pest of melinjo (Gnetum gnemon L.), with symptoms of leaf yellowing and premature falls, which lead into light canopy appearance and low economic yield. To know the intrinsic natural increase rate of its population, the experime...
