Abstract: Soil insects are
insects that live in thesurface of soil and living in the soil. The current
of soil insects population on agricultural ecosystems very rare as a result of
intensive farming and modern farming practices using synthetic chemical
fertilizers and synthetic insecticides. Another problem is the lack information
of soil insects contained in agricultural ecosystems Brantas Watershed
Sumberejo Batu.The research aims to determine of the spesies, parameters of
ecology, species diversity index, and evenness index contained in agricultural
ecosystems Brantas Watershed Sumberejo Batu. This research used descriptive
quantitative research. This research carried out in the morning with the plot
method(squares) and using Pitfalls Trap. Datawere collected by direct
observation of the population investigated. The results showed that soil
insects were found to consist of a species Pheidole capellinii, Iridomyrmex sp,
Pachycondyla sp, Camponotus sp, Monomorium sp, Pheropsophus occipital, Gabrius
sp, dan Teleogryllus siamensis. Soil insect of ecology parametersare: (1)
density ranged from 4,15 ind/m2 – 27,26 ind/m2, relative density between
0,01-0,09, The highest density of species is
Pheidole capellinii, and lowest is Monomorium sp. (2) frequency ranged
between 0,15-0,63, the relative frequency ranged from 0,04-0,16 with the
highest frequency value of species is Pheidole capellinii 0,94, and lowest is Monomorium sp. 0,06. (3)
the highest Importance Index Valueof species is Pheidole capellinii 0,25, the
lowest is Monomorium sp. 0,06. Index of diversity values Shannon wiener (H') of
0,73 or categories is very low diversity values. Index of Evenness(E) is 0,33
which means that the population tends to be unevenor low(E <0.4).
