controlling the grub manually

To control the grub knowledge of the life cycle of the grub is essential.It is said that in the evening ,after sunset beetles can be collected manually.Normally beetles emerges after pre-monsoon showers ,may be in the month of May-June.After emerging from the soil it sits or fly's at about 4 feet height.After mating it lays eggs in the soil and flies higher in search of food.Begane Kadappa Gowda controls the grub problem by collecting it manually.But the method needs very high concentration and affort,I personally failed to collect even a single grub this year.Each female beetles lays about 50 eggs and collecting one beetle means destroying 50 would be grubs. After one month of the beetle emergence little larvae can be found in the soil.This happens around in the end of July month.By forking the land grubs can be found and collected manually.Dr.A.R.V.Kumar says that if the right method is employed 99percent of the grubs could be destroyed by this. If we want to apply the chemicals this is the right time to apply it. In the month of September -October third stage grubs can be found in depth of the soil.Now the drainage canals must be blocked to increase the water level.As the water level increases the grubs comes to the top soil within 3-4 days.Grubs can be collected after forking the land. To control the grubs timing and methodology is very important otherwise we are spending only the time and money over it .
