Background

This information was provided by state coordinators and was collected from surveys of county agents,

Extension specialists, private consultants and research entomologists.

All data are averaged over a total reporting unit, state, etc. For example, if a unit report represents 100

acres and an eight percent loss on 25 of these acres, then in the table summary this shows up as a total

2% loss. This type of averaging is used for all data reported including yields and costs of control.

Highlights

From the high of over 2% in 1991, aphid damage decreased to an estimated 0.29% in 1992. The traditional big three rebounded with boll/budworms at 2.21%, boll weevils at 2.12% and Lygus at 0.89%.

Even though estimated overall losses were small, several secondary pests infested significant acreage.

These includeboth beet and fall armyworms infesting over two million acres each, banded wing whiteflies and Western flower thrips about two million almost 800,000 acres and European corn borer infesting over 400,000 acres. Total losses were up from 5.63%in 1991 to 6.90% in 1992. Cost of control increased from $33.39 in 1991 to $46.81 in 1992.
