      abstract = {Western corn rootworm (WCR) appeared in Serbia in the late  80’s and quickly spread,
causing increasing losses.  Monitoring showed that crop rotation gives good results.  On
the other hand, domestic animals require a lot of corn  and considering the limited landarea,
that often demands  repeated sowing of corn (continuous cropping),  consequently
leading to higher pest damages. Through Farmer  Field Schools, farmers were educated on
WCR risk assessment  of repeated corn sowing. The goal was to prolong corn  production
over years, presuming its higher profitability  of production (gross margin). Calculations
of production of  wheat, corn and soybean on farms involved in education  program in
2012, have shown that corn has the highest gross  margin (92,047.50 RSD/ha), followed
by soybean (72,410.00  RSD/ha) and wheat (59,510.00 RSD/ha). It could be  concluded
that farmer’s best interest is to grow corn, when  possible, in continuous cropping, with
obligatory risk  assessment.},
