Scientists are working to find a solution to soybean aphids.  Aphids have the potential to destroy 40% of the soybean crop, so finding a way to reduce them is essential.  Researchers are experimenting with resistant soybeans and Binodoxys communis a tiny insect that lays eggs in aphids.  When the eggs hatch, the aphid is killed and the larvae feeds on the body as it grows to adulthood.  Both the aphid and the parasitic insect are originally from Asia, so testing must be done regarding the consequences of release before the US Department of Agriculture approves the release of the parasite.  For more information, see PhysOrg.
