Show THE LEADER, Alfalfa Weevil Control By George F. Knowlton, Extension Entomologist Utah State Agricultural College The alfalfa weevil is a serious pest in Utah practically every year. Damage was somewhat less serious in 1952 than most seasons, due to the very rapid growth of the crop which occurred after the high spring water receded and permitted the crop to grow. However, in 1951 the alfalfa weevil caused great damage in most areas where early spring control had been neglected. The new alfalfa weevil con-t- trol program, developed by US Utah Agricultural Experiment DA entomologist F. V. Lieber-ma- n Station, and entomologists and his associates at the working in Montana and other states, has proven that this pest can be controlled economically by destroying the overwintered adult weevils. Control, however, must be accomplished BEFORE the female weevils lay many eggs. Otherwise the eggs will hatch and become worms to feed on alfalfa foliage during June and early July. A new insecticide called will enter the alfalfa weevil control picture in Utah and much of the northwest, this season.

Control chemicals were adequate in supply for all Utah needs in 1952. They should again be adequate to most all 1953 weevil control needs. Possibly a little information on the seasonal history of the alfalfa weevil will help us to understand the control problems: Adult weevils emerge from cocoons in the fields from May to August. Most of the emerged weevils survive on through the next winter. Some females deposit a few eggs in the fall. Many more eggs are laid during the following spring. At first eggs are laid only in small fragments of dead alfalfa and grass stems. However, after the spring alfalfa growth becomes 6 inches tall, more and more eggs are laid in growing alfalfa stems. Each female weevil deposits from 200 to 800 eggs. Only small numbers of larvae hatch before May 1. Larvae become damagjngly abundant during late May to early June. Each larva molts three times before cocoon spinning its among leaves on or near the surface of the ground. Pupation occurs in this cocoon. When meeting with farmer groups to discuss alfalfa weevil control, I have often been askech "Why spray when first growth is only one to two inches high? Why can't we spray later, say at 4 to 6 inches growth?" Our answer is that only a few eggs are laid in fall, and more deposited as the females reach sexual maturity and lay eggs in spring. We lose much of the benefit of the early spring treatment when we allow an extra interval of time to pass. This permits thousands of addi tional eggs per acre to be laid ny tne weevils. There is little point in killing the weevils AFTER they lay their eggs. The early spring treatment does not destroy the eggs, nor the worms, after they are hatched out. It is aimed to kill the adults. We must do this BE FORE eggs are laid. You might can this "preventive insect control". Could anything be better than to PREVENT worm damage to first crop, avoid any growth delay between first crop being cut and the new growth appearing on second crop? This keeps the quality of alfalfa "tops" and that counts as much as tonnage in a. hay crop. Every year farmers ask "Is it as good if we apply a dust instead of a spray?" We say "No." Research by our Legume Seed Laboratory entomologists has regularly indicated a bet ter control irom a given amount of insecticide when it was applies as a SPRAY, rather than a dust. Thf samp 3nn1ia HfJU.ll J some extent with DDT and applications made later on the alfalfa seed crop. In those cases we must step up the dosage to two full of DDT or texaphone as apounds DUST for best lygus bug control, when research has shown that one and one-hapounds of either chemical, applied as a SPRAY, gives equally good and lasting control.
