Summer Crop Insects: Bean Leaf Beetle Foliage Damage

What to watch for . . . Almost every field season has its particular insect problems and surprising‘ gotcha’ moments (we’re looking at you, fall armyworm.)  But there is a seasonality to our common insect pests in agriculture, and this article outlines a few of the things to look out for in the remaining months of summer. 


  • Soybean defoliators of various types (caterpillars, Japanese beetles, etc.) often make their first appearances in July. Thresholds for defoliation in soybean have recently been revised to take into account modern crop values and input costs. Soybeans can tolerate a surprising amount of defoliation and still compensate for a good yield, so don’t pull the trigger too soon. When deciding when to spray, make your decision based on the average condition across the whole field. Many soybean defoliators are concentrated on the edge and spraying the whole field will not provide an economic return.
  • Potato leafhoppers are a potential threat to alfalfa from July through September.
  • July is Western bean cutworm month in corn, but this pest varies widely from year to year. The flight usually begins in mid-June, but peak flight usually occurs in Mid-July.
  • Stink bugs in soybean make their first appearances as pods begin to form.  From R3 onward, keep an eye on them.  This is another edge pest, and swelling populations can benefit from an edge application when needed.


  • Keep watching those potato leafhoppers in alfalfa.
  • Defoliators and stink bugs in soybean tend to ramp up in August so keep these on your radar screen.
  • Spider mites can strike many different crops during periods of sustained hot a dry weather, which can happen at any time of year but happens most commonly in August.  There are several newer miticides on the market which are very effective when used timely.
  • Remember soybean aphids?  They are still a pest, but not as significant as before. If your field is infested, now is the time when they can cause damage.


  • If you have late-planted soybeans that are still green in September when other beans are maturing, they will be a magnet for both stink bugs and bean leaf beetles. Bean leaf beetles feeding on foliage are seldom a problem earlier in the season. But pod feeding on late-season beans holds more damage potential, through direct damage to the seed and also through the introduction of disease.
  • When planting winter wheat, be mindful of the fly-free date for your county. Planting after this date can help minimize damage from Hessian fly and also feeding by aphids which can transmit disease, especially barley yellow dwarf virus.

How Your Revenue Policy Works

As market prices decline, there is a growing need to understand how your crop insurance revenue policy works.

Revenue policies guarantee a certain level of revenue rather than just production. It protects from a decline in crop prices or yield.  Your crop coverage guarantee is based on the futures market and your yield history. Both are used to compute your revenue coverage and guarantee. The monthly average of the crop futures price for the month of February determines the spring crop price. A harvest price is determined in November using the new crop futures price during the month of October. The final revenue guarantee is computed by multiplying the higher of (projected price or harvest price x yield x your coverage level.) If your actual revenue falls below the revenue guarantee, you’ll receive a crop insurance indemnity equal to the difference. 

Please keep good production records. Given current price levels, it’s important to submit your production information to us as soon as you are done harvesting so we can determine if you qualify for an indemnity payment.
