Too bad Canine Heritage is going out of the DNA testing business. I've had 4 mixed breed dogs tested by them, two of them also by Wisdom. Didn't send any pictures to either. Canine Heritage was quite accurate on all 4, whereas Wisdom faltered on both less than at least 50%.
The lettuce root aphid is a soil dweller that attacks lettuce roots in spring and summer, causing lettuce plants to wilt and occasionally die. In fall, this species often moves to poplar trees, where it overwinters in the egg stage and produces leaf galls in spring.
Many species are green but other commonly occurring species may be white and wooly or black. Aphids are among the most destructive insect pests on cultivated plants in temperate regions. The damage they do to plants has made them enemies of farmers and gardeners the world over. From a zoological standpoint they are a highly successful group of organisms.
