|Description:||Magnified 240X, this photomicrograph revealed the presence of a Heterodera sp. nematode egg.|
Heterodera sp. roundworms, are also known as soybean cyst worms. It has been noted that these worms move very little, and therefore, contamination of fields is usually due to the transfer of these organisms in the processes involved in farming, or by natural phenomenon such as attached to birds, or the wind.
