We studied the effect of environmental complexity and plant architecture on the abundance of the Edessa rufomarginata bugs in pastures and cerrado areas and its biology.We observed higher number of bugs on Caryocar brasiliense trees in the cerrado than pasture areas.Bugs were more abundant on leaves and branches rather than fruits.Caryocar brasiliense had greatest fruit production on pasture than in the cerrado areas.

The abundance of bugs was correlated positively with aluminum, organic matter, and tree height, but negatively correlated by soil pH.Productivity of C.brasiliense merlot redbud tree for sale were negatively correlated with aluminum, pH, and number of bugs, but positively correlated with phosphorus and calcium.The number of eggs per clutch was 14.

3, their viability was 93% and the embryonic period was 6.9 days.The respective length and width of each instar were: first instar 3.3 mm and 2.

4 mm, second 4.1 mm and 3.0 mm, third 6.7 mm and 3.

0mm, and fourth 11.5 mm and 3.5 mm.The respective length and width of adults were: males, 15.

8 mm and 8.6 mm and females, 17.3 mm and 9.1 mm.

The sex ratio was 0.43, and gtech brush bar the total duration of the life cycle of E.rufomarginata was 156 days.
