Defending Cotton from Stink Bugs
January 25, 2008| |
The cotton stink bug has become one of the major problem for US cotton growers, costing them about 3 percent of crop loss annually. Scientists from the Agricultural Research Service (US ARS) are now testing a combination of trap crops and pheromone traps in combating the stink bugs. Trap crops are special plants planted to lure pest away from cash crops. Pheromones, on the other hand, are chemicals produced by insects, usually as attractants. Results of field experiments are promising. Researchers planted sorghum as a trap crop in peanut and cotton fields. They also place pheromone-baited capture traps about 45 to 50 feet apart in the sorghum strips. The stink bug population was significantly lower in cotton fields with the sorghum and pheromone traps than in those without them.
