Researchers studying data from fields in 20 countries have found that managed honey bees are not as successful at pollinating crops as wild insects, primarily wild bees, suggesting the continuing loss of wild insects in many agricultural landscapes has negative consequences for crop harvests. The study, which prompts an urgent call to maintain and manage pollinator diversity for long-term. insects in farm fields is detected by erecting boards covered with a sticky material and then examining the insects trapped on the boards. To investigate which colors are most attractive to the cereal leaf beetles, researchers placed six boards of each of four colors in a field of oats.

The local dispersal of polyphagous, mobile insects within agricultural systems impacts pest management. In the mid-Atlantic region of the United States, stink bugs, especially the invasive Halyomorpha halys (Stål ), contribute to economic losses across a range of cropping systems. Here, we characterized the density of stink bugs along the field edges of field corn and soybean at different Cited by:   In field crops, the problems with insects are much bigger.
