I had more calls this week about sugarcane beetles, chinch bugs, colaspis and bill bugs in rice in Southwestern Louisiana. In the majority of these fields, no insecticide seed treatment had been applied to the seed. The best response is to bring a flood as soon as possible. If this isn’t possible, some crop advisors have reported substantial improvement in the stand following  a pyrethroid spray and holding a light flush for a couple of days.

If you’d like to see a video of a sugarcane beetle digging back into the soil after I removed it from the soil you can click here. Thanks to Extension Entomologist Kathy Flanders at Auburn University for posting the video on my behalf. I shot this video at a field we scouted with Barrett Courville and Benet Augustine last week.

After doing more research on the bill bugs we collected, we found that we have not one, but four species of bill bugs that were collected from a single field. We are doing more work to tease out the species complex that occurs in south Louisiana. If you find any bill bugs in rice please get them to your local county agent and ask them to deliver to me. You can simply throw then in a ziploc bag and kill in the freezer. Please write the farmer name (or some other way to note the field location) and date on the bag. If you can record gps coordinates and e-mail to me that would be a real help. 

Update on the LSU AgCenter rice water weevil demonstration test:

We planted our final field location in Avoyelles Parish on April 27, 2011. We have a stand of rice and will take data on the stand on May 23, 2011. The majority of our other demonstration locations are at or near permanent flood. We will be running around pulling core samples from all the locations in the middle of June. To learn more about rice water weevil biology and our sampling methods you can watch this video

Field meeting season will kick off soon.

Please mark the following dates on your calendar:

June 1, 2011: Rice field tour in Welsh, LA. I will post an agenda soon. I’ll be in hand to discuss rice insect management and field observations.

June 15, 2011: LSU AgCenter South Farm Tour in Crowley, LA. We will have a meeting at our rice water weevil demo test site on the Simon Farm, which will include a sponsored lunch (Special thanks to our sponsors: John Bordlee – Valent; Toby McCown – Dupont, and Josh Zaunbrecher – Syngenta). 

June 30, 2011: LSU AgCenter Rice Research Station Field Day in Crowley, LA.
