I knew my phone was too quiet last week…

Today I’ve have four calls about insect problems in rice. Yesterday I ran the battery down on my phone between phone calls, e-mails and tweeting field observations. Which reminds me, if you are using twitter, you are welcome to follow me @NatHummel for field updates.

These dry conditions are exacerbating problems in drilled rice, which in many cases is dry, dry, dry. We need some rain. The wind is not helping the situation. One consultant, who has decades of experience in rice, called today to tell me he would appreciate more training in identification of uncommon insect problems – namely aphids, thrips and chinch bugs. As we shift away from water-seeded to drill-seeded rice these insects have the potential to become more common pest problems. It looks like that might be happening this year.

This blog posting will focus on many of those “secondary pests” which we happened to observe in Evangeline Parish yesterday. Before I get to that, just a quick update on what is becoming the chinch bug situation.

In Jeff-Davis Parish I have now heard of four additional locations which suffered from infestations of chinch bugs. This brings the count to about 8 to 10 sites with chinch bugs infestations. Some had been treated with Dermacor X-100, but remember Dermacor will not control chinch bugs. CruiserMaxx and NipsitInside should provide control (refer to previous postings about difference in seed treatments for more details). It has been noted that drilled hybrid rice, planted at low seeding rates, needs to be carefully scouted for chinch bugs. This is true primarily because in a field with a low seeding rate, the number of plants per acre is substantially lower than in field planted at a conventional seeding rate. When an insect (such as chinch bugs) infests a field with few plants to begin with, they can cause substantially more injury more quickly than in a field with a thicker stand.

Chinch bugs can be difficult to scout because they have a habit of hiding in cracks during the heat of the day and also because they often feed at the soil line near the base of the plant. This injury caused by feeding on the heart of the rice plant is what causes the rice to throw a red or orange leaf and eventually die from injury. To treat an infestation it is best to apply a flood or flush water across the field and then follow with a pyrethroid insecticide – this strategy drives the insects up onto the plant allowing them to be exposed to the insecticide.

You can click on the pictures to make them larger.

In Evangeline Parish we found a few chinch bugs feeding on the plants.

 We also found a mating pair of chinch bugs on the soil surface between the rows.  Just to illustrate how difficult these can be to scout, can you find the chinch bugs in this picture?

 As I was taking pictures, they shifted position – here is a close-up.

Chinch bug mating pair.

After mating, chinch bugs will deposit eggs, from which first instar nymphs will hatch. We did see some first-instar chinch bugs near the base of the plant.  The first instars look very different from older stages – are very small and bright orange in color.  Here is a composite picture from my files for your reference – these pictures were taken in Jeff-Davis Parish a couple of years back.


Yesterday, Anna and I took stand data at the Evangeline Parish Demo test site.  Here is the field map. (I’m in the process of building LSU AgCenter websites for each of the test sites, but suddenly time at my desk is precious and rare). The field is located between Ville Platte and Vidrine at these GPS coordinates: 30°41’42.66″N, 92°24’23.80″W. The plots are flagged with colored flagging according to treatment.

The variety XL745 was planted at a 25 pound/acre seeding rate on March 21, 2011.  First emergence was noted on April 5, 2011. Yesterday, we visited the site two weeks after emergence to take observations on the stand. At this location we are comparing the three seed treatments (CruiserMaxx, Dermacor X-100 and NipsitInside) to an untreated check.

In general, there does not appear to be a significant difference between treatments, but the untreated cuts do not look quite as vigorous.  We will wait to summarize all the stand count data from all sites before making definitive statements about any effect of seed treatments on the stand vigor. Following is a series of field shots comparing the treated strips.

As we walked across the field site we noticed many fire ants and also parasitoid wasps, which led us to believe there must have been some insects in the field that these predators/parasitoids were consuming.  Sure enough, after some searching we started to find aphids, thrips and chinch bugs.  None are present at levels that are causing noticeable injury in the plots, but we will certainly keep an eye on the populations.


Fire ants foraging in the Evangeline Parish test site field.

In this situation, the fire ants are helping us by eating some of the insects that are attacking the rice – including aphids, thrips, and possibly chinch bugs. Of course, they also took a couple of bites out of me  as I was attempting to take picture in the windy conditions at the field.

Thrip adult on a rice plant leaf blade - we commonly found them on the blade or in the leaf sheath area. It appeared that feeding injury was causing discoloration on the sheath, but this was not confirmed.


We found a few aphids on some of the plants. It is likely that populations would be higher if they were not being attacked by ladybugs.

Ladybugs were also present in the field eating the aphids.

 The herbicides had not gone out yet, they will probably go out today, and so we took a few moments to enjoy a sweet gift of nature – wild blackberries on the edge of the field.

Anna picking blackberries during lunch break – ah the sweet rewards of field work…

Tomorrow we will make some site visits in Jeff-Davis where possible colaspis injury has been reported. In the afternoon, we will head to St. Landry Parish to take stand counts at our demonstration site.

It’s almost that time of year again.  Today Anna and I met with County Agent Keith Fontenot and Evangeline Parish farmer Kenneth LaHaye to discuss plans for the 2011 rice water weevil demonstration test.  Kent Guillory is the consultant who will assist with monitoring this test location.

Mr. Kenneth LaHaye, County Agent Keith Fontenot, and me discussing plans for the demo test in Evangeline Parish.

This will be the third year that we have worked with Kenneth (and his dog Harley) on a demo test site. We appreciate his continuing support of our on-farm demonstration program. The last two years we worked with Kenneth near Chicot Lake.  This year, our test site is located near Vidrine on La-10. We will provide directions to the field after planting.

Kenneth's dog Harley - she makes for great company in farm work.

In the 2011 rww demonstration test we will restrict our insecticides to the three different seed treatments that are now available on the market.  These will be compared to an untreated check.  The table below compares these products:

Kenneth will be planting RiceTec variety XL745 at a 25 pound per acre seeding rate.  The seed treatments will be arranged in two blocks, with one rep in each block.  Each rep will include two 20 ft drill passes.  We intend to plant sometime between March 12 and 15, if the weather cooperates.  Kenneth has already prepared the land for planting.   A herbicide burndown of 32 oz/acre generic roundup and 2 oz/acre Valor was applied in November, 2010.  When looking at the field we noticed some areas where his burndown did not provide control.

The weedy strips in the field are the result of tapping the boom and turning off an outside nozzle.

Kenneth asked us to post this picture to illustrate how effective a burndown put out in November can be. The missed passes in the field are the perfect example of what he could have been fighting as he prepared to plant, had he decided to wait until spring to apply his burndown.  Last season Kenneth grew soybeans in this field.  Rice will be drilled into the stale seedbed at around 25 pounds per acre.  This soybean-rice rotation can sometimes be conducive to injury from the colaspis beetle.  We’ll be sure to monitor for injury from this pest when we take stand counts two weeks after emergence.

We’ve been busy collecting rice water weevil cores samples all over Louisiana for the last couple of weeks.  By the end of next week, we will have sampled most of our sites.  The northern locations will be sampled later in the season.  We are still gathering, entering, and analyzing data, but I wanted to give you a little preview.

Rice water weevil field crew - Tiffany, Lukas, Anna, Nick and I. We've been having fun out in the field this summer.

In general, the populations are higher in Evangeline Parish than Acadia Parish.  At one of our sites, the counts were up above ten on average.  At another location we had 51 larvae in one core sample – this was hybrid rice in an untreated check.  With the size of hybrid plants, we can usually fit one plant in a core.   The other samples in the untreated check  at that site were mostly above ten, and a few near 20, so this is a pretty high population.  Previous research has indicated that a single larva per core can cause .5 to 1.5% yield loss.  Anything above 5 larvae per core is above our economic threshold for treatment.

Lukas and Nick washing the mud off the rice plant roots. Mud is filtered through a seive which leaves behind bits of roots, rice water weevil larvae and pupae.

Plant in a seive - first we count the number of plants per core sample, then we float the sample in a salt solution.

This is what it looks like when the larvae are floated in a salt solution. Each yellow circle surrounds a rice water weevil larvae. The root tips (red arrow) are similar in appearance, but lack the ridged segmentation of larvae. The larvae are counted and sized as small, medium, large to assess the relative stage of development.

Once the data are entered, I’ll start posting some summary tables for the different sites.  We will have a total of 13 to 15 sites this season, so we will have a lot of data to discuss at summer and winter meetings.

We take our core samples 4 weeks after flood.  They are taken at this time, because many years of research indicate this will be a peak in the larval population.  Last week, I noticed that a lot of the larvae are large in size and we’ve also found pupae in samples.  It looks like weevil populations in early planted rice will be pupating and emerging as adults over the next two weeks.  If you have late planted rice that will be going to a flood soon, I would encourage you to monitor closely for adult weevils, and be sure you don’t miss optimal insecticide timing.  Weevils that emerge from early-planted rice will either enter bayous or neighboring late-planted rice fields.

Today we met with Mr. BD Fontenot to gather cores from a test site in Evangeline Parish.  BD identified the test plots for us and then headed out to scout fields.  Before he left, he received a call reporting that rice, which was happy and healthy last week, had suddenly started to die on one edge of the field.  BD scouted the field and called to report excessive chinch bug populations and injury.  This is an 85 acre field of CL151 planted on April 17, 2010 that is just starting to tiller.  The damage is pretty severe, but quick action will probably save the rest of the field.

Chinch bugs marching across the field from the edge.

Fallow field, dying weeds on levee and infested field. Most likely the chinch bugs moved from the dying grasses into the growing rice.

Dehydrated and dying plants were occassionally found near healthy plants that were starting to dehydrate. This was commonly found on the advancing edge of the infestation.

The brown specks on the plants are chinch bug nymphs and adults. We saw upwards of 30 chinch bugs per plants.

Chinch bugs clustered onto a rice plant - they prefer the shady side. The sun was nearly due overhead when we scouted, but it was still fairly cool out so they were up on the plants.

We also found nymphs near the soil line. This tendency to feed at the base of the plant and on growing points is what causes rice to stunt and die as a result of chinch bug injury.

Adult chinch bugs have a black and white hour glass pattern on their wings. We found a few adults, but the majority were third to fourth instar nymphs.

BD plans to apply Karate with the second application of Newpath and then bring on permanent flood as soon as possible.  Water was already moving into one of the cuts.

Applying a flood or flush to the field should help this problem, but in this case the population is large enough to warrant a pyrethroid application.

Field crew members Tiffany, Nick and Lukas sweeping for chinch bugs.

If you suspect you have a chinch bug problem, it is best to sweep using a net early in the morning to scout the field.  Later in the day, when it is warm, the chinch bugs will move into the soil cracks and can be extremely difficult to find.  Symptoms of chinch bug damage using include a red to orange leaf, in this field most of the plants that were injured were already starting to die.  I didn’t notice the same typical red/orange leaf that you will see in older rice.

Hopefully Karate in application with a permanent flood will prevent further damage.  Today I also had reports of more fields with thrips damage in St. Landry Parish and more rice water weevil injury.  The insects don’t seem to mind this warm, dry weather.
