Rice Insect Update Updated

🕔09:14, 13.May 2011

The reason for this post is to give an update on insect pests that we may be seeing in the near and distant future. First, we had several wheat fields around the Delta that had some fall armyworms. In addition, we are seeing a fair number of fall armyworms in whorl stage corn. I wouldn’t say the numbers we are seeing are anything of great concern, but the numbers are higher than we normally see this time of year. This tells us that fall armyworms are in the environment and capable of moving into rice. As the wheat is drying down, make sure to keep a close eye on field edges, especially those fields adjacent to wheat.

Aphid Numbers Crashing in Mississippi Wheat Fields Updated

🕔09:49, 7.Apr 2011

Over the last 5-7 days aphid numbers have started crashing in wheat fields around the state. Our wheat test in Starkville went from several hundred per row foot on April 1st to less than 10 on April 4. Many consultants and dealers have told me they are seeing the same thing. A lot of this can be attributed to parasitized aphids from Lysiphlebus testaceipes (small parasitic wasp) but other cases may be contributed to various diseases that will take out aphid populations.
