Show bird beetles were bought and shipped into Utah last season to help control pea aphid, growers and canners cooperating in this purchase. One of the worst enegies of the plant aphid is a green, slug-like magget about half and inch long, often marked with whitish stripes.i It is confusing to observe these maggots in company with defin- itely injurious aphids, but Dr. : Knowlton explains that they are feeding on the other Insects. The adult of these worms is the small, yellow, b'ack-banded bee like syrphus fly, he says. Ground beetles, lace-wing flies, and tachna flies also reduce the number of injurious insects which feed upon garden plants. i Farm Garden Protected by Some Insects ! All insects are not pests, according accord-ing to Dr. George F. Knowlton, associate entomologist at the U.S. A.C. It is a wise gardner who realizes and capitalizes on this fact, Dr. Knowlton explains. That familiar 'little orange beetle beet-le with the small black spots more commonly described as the 'jLady Bug or Lady Bird is one of the types of insects which are beneficial to the farm! garden. Lady beetles not only eat the plant iice and aphids which attack a number of the common garden plants, but they also eat the eggs pf many injurious insects. ' Modern entomologists, Dr. Knowlton Knowl-ton points out, find that both adult and larva of the lady beetle are one of the best aphid exterminators exter-minators because a single bettle requires from 5 to 80 pant lice or aphids a day for food. The pre- ' Jience of this insect should therefore there-fore bs encouraged, and it should be recognized that he is a protection pro-tection rather thsn an evil, h3 says. Ten million convergent lady- |
