Bollworms in Dual Gene Bt Cotton: Control and Expectations

Bollworms in Dual Gene Bt Cotton: Control and Expectations Updated

👤Angus Catchot, Extension Entomologist 🕔07:29, 15.Aug 2014

Over the last 7 days we have had numerous reports of high bollworm numbers in some BollGard II, TwinLink, and WideStrike fields in the Mississippi Delta. We have seen fields in the past that reach treatable levels but some reports are much higher than we have seen in recent years. At this time there does not appear to be any specific varieties that are adversely affected more than others. It appears to be a function of high pressure in isolated areas at this time.

After 4 weeks of high bollworm moth catches averaging more than 75 moths/trap/week, this week has dropped down to an average catch of 35 moths/trap. This should mean that once current worm populations are controlled, a substantial reinfestation is not likely. However, tobacco

White Sugarcane Aphid Update – 8/1/2014 Updated

👤Jeff Gore, Research and Extension Entomologist 🕔09:48, 1.Aug 2014

White sugarcane aphid infestations are increasing across the state and more applications are going out to manage this pest. Over the last week to 10 days we have heard about numerous fields that have received a second application. Remember, that the Section 18 label for Transform states that no more than 2 applications can be made in a field.

Managing Cotton Aphids in 2014 Updated

👤Jeff Gore, Research and Extension Entomologist 🕔16:11, 25.Jul 2014

We had a few calls over the last week about poor control of cotton aphid with Transform. In all of those cases, the field was actually sprayed for plant bugs with a 1.5 oz rate of Transform. That rate should be very effective on cotton aphid based on previous experience. As a result, we collected aphids from three different fields this week to test their susceptibility to Transform.

Rice Stink Bugs in Mississippi Rice Updated

👤Jeff Gore, Research and Extension Entomologist 🕔20:58, 24.Jul 2014

As more and more of the rice crop starts to head, it is time to start thinking about rice stink bug. We have been sweeping some grass around the Delta for the last few weeks, and the one general comment I will make is that populations have been fairly low in most areas. We have seen fairly high numbers in a couple places, but it was small patches of heading grass in isolated locations.

Treating White Sugarcane Aphid: Decision Aid

Treating White Sugarcane Aphid: Decision Aid Updated

👤Angus Catchot, Extension Entomologist 🕔14:26, 15.Jul 2014

White sugarcane aphids (WSCA) have been blowing up quickly to treatable levels in several counties in Mississippi. Over the last few days here have been several field requiring treatments likely with more coming. Because this is a new pests for Mississippi, we have been following the lead of our colleagues in Texas and Louisiana who dealt with this in 2013. Below are some criteria that we put together based on what we know to date that will help in making a decision to treat WSCA.

Populations of the white sugarcane aphid are expanding and increasing across the state. We have confirmed the presence of white sugarcane aphid in grain sorghum in 7 counties in Mississippi (Fig 1) and there are likely more. The counties where white sugarcane aphids have been found include Bolivar, Washington, Humphreys, Quitman, Panola, Tunica and Oktibbeha.

By now most folks have heard of Kudzu bugs. In fact, we have now confirmed them in 52 counties in Mississippi. Kudzu bugs, Megacopta cribraria, was first found in Georgia in 2009. Since that time it has spread rapidly across the southeast kudzu bug map 7_8and is now moving west in to Mid-southern states. It was first found in Mississippi in 2012 and now covers most of the state.

White Sugarcane Aphid: A Potentially Devastating Pest of Grain Sorghum Updated

👤Angus Catchot, Extension Entomologist 🕔10:25, 26.Jun 2014

In 2013 a new aphid pest called the White Sugarcane Aphid, Melanaphis sacchari, was detected in grain sorghum in 38 counties in Texas, Louisiana, Oklahoma, and one county in Mississippi. This species has apparently been around for years but the hosts switch to grain sorghum appears to be new. This pest can be devastating to grain sorghum if populations reach high densities. In fact, some fields have seen 100% yield loss. Another major factor is this aphid is difficult to control with currently labeled products.

Importance of Monitoring Square Retention in Young Cotton Updated

👤Angus Catchot, Extension Entomologist 🕔14:23, 19.Jun 2014

Square retention is a critical component of early season plant bug management. I would strongly encourage you to take square retention counts along with your sweep net counts prior to bloom. Not only does this help in the decision making process of treating plant bugs, but it also helps you to get a better idea of how the products you are applying are working. Numbers alone can be deceiving when adults are steady moving into the field. When large numbers of adults are migrating into a field it is not uncommon to have as many or more plant bugs 4-5 days after a spray than you did before you sprayed and it still would not equate to a control failure.
