Parameters observed were the attacktion  level in the land, attacktion  intensity, production per hectare, environmental sanitation conditions. The rats attacktion  rate of  100%, means that all sample  in one stretch of   plantation  have been   attackted by rats, it was indicated by a bite scars on the harvested fresh fruit bunches. The attacktion intensity of the bush rat pest was 23%. The average production was 21.6 tons/hectare/year.
