Soldier Beetles, Not Blister Beetles

Image
A Lubbock County grower came to my office this morning with a bottle that held 20 or so beetles he collected from the edge of a field. His concern was that they were blister beetles, and I was pleased to be able to say that they were soldier beetles. However, given the high numbers he described in the field, soldier beetles must be very abundant this year. Photo credits: Ed Bynum and Pat Porter There is some resemblance, but these beetles are different enough to be separated on sight. One problem though is that he showed me a web page that incorrectly identified soldier beetles as blister beetles; the internet strikes again. Texas growers can always send us a photo of an insect if they want an identification. Soldier beetles, insect Family Cantharidae, are predacious on other insects as both adults and larvae. Blister beetle larvae, insect Family Meloidae, are predacious on grasshopper eggs and the larvae of wild bees. When disturbed, blister beetles exude hemolymph (the insect versio...

Headworms Up; New Invasive Aphid Found in Panhandle

Image
Headworms and Late Corn Fall Armyworm Corn earworm and fall armyworm adult trap captures are up significantly in the last week and this means headed sorghum should be scouted for headworms. It also means that late planted non-Bt corn should be scouted for fall armyworm. Corn earworm is not an economic problem in corn, but fall armyworm can do a lot of damage to ears if it infests them prior to hard dough stage. Prevathon and Belt are good choices for control of fall armyworm in corn and they will not flare spider mites (which are also being found readily in corn and sorghum). As headworm insecticides they will not flare sugarcane aphids in sorghum.  New Invasive Aphid Pest Sipha maydis, which we are choosing to call the hedgehog aphid after Colorado State University's lead, was found in Lipscomb and Hockley counties on sorghum on the same day last week. Given the distance between discoveries it is likely that the aphid is widely distributed on the High Plains and we ...

What's Up With All the Earworms in Bt Corn?

This is a jointly issued article from Extension Entomologists Drs. Pat Porter (Lubbock) and Ed Bynum (Amarillo). There are large numbers of corn earworm larvae in Bt corn ears in the Texas Panhandle, and some people are spraying in an attempt to control them.  The first question we are getting is what to spray, but the better question would be whether to spray.  Corn earworm is usually an ear tip feeder, and on its own is seldom an economic pest of corn. However, this year we are seeing earworms doing more than just tip damage, and feeding lower in the ear. The reason(s) for this change in behavior are unknown.  We have not forgotten last year though, when there was good evidence that just a little ear tip damage resulted in higher fumonisin levels. This could happen again this year, especially if the weather in August and September turns off wet and relatively cool. However, based on what we saw last year, the little bit of tip damage needed to promote fumonisin has alre...
