Mass hunting is practiced in areas where some pest damage is acceptable to reduce the pistachio wholesale use of insecticides. For example, in parks and plants on city streets, 80-90% control can be acceptable. In general, it can be said that mass hunting is useful when the pest density is low in the affected areas. Second, the migration of the pest from the outside into the test area is limited (isolated gardens). Therefore, pest population assessment based on the records of previous years is absolutely necessary and will be an effective aid in deciding to use this method (Mehrazin, 2009).
Attract and Kill Method
The method of killing and slaughter is one of the tactics or strategies of pest control, which is similar to mass hunting and based on the system of pest control and eradication (elimination) of a significant part of the pest population and thus prevent crop damage. The main difference is in the method of capture and killing, relying on a toxic substance that kills more than one trap. The most important benefit of this method is that the problem of trap saturation by the removed pest can thus improve the pest control performance at high densities. The consequences of switching traps and the high cost of the control program are also limited. The method of capture and killing can be used to control all kinds of hard-shelled moths, butterflies and especially flies.
