As in the interpretation of the act of oil on eggs developed several theories to explain the way to kill the other stages of the insect, is that the oil spreads through the respiratory openings Spiracles and block the tracheae Tracheae and die the suffocation Suffocation Suffocation It was noted that oil reaches the body of the cortical insect through the edge of the crust Armoar quickly More than the middle part of them.
He said that the insect, which receives an insufficient dose of the suffocation may occur death as a result of oil inside or outside the body of the insect for a long time, causing disruption in physiological processes, and another factor added to the act of oil killer is that the layer of oil stable on the leaves, It is noted that heavy oils inhibit nymphs from stabilizing more easily than light oils. It is observed that incomplete stages of cortical insects die easily from complete insects.
