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.
The life history of many aphids is complex and unusual. Enormous populations of aphids can be built up in a short period of time. Although considerable variation occurs between species, a typical life history is described as follows.Aphids generally overwinter as fertilized eggs.hey feed on both coniferous and deciduous plants. Effective control of aphids has been a problem to homeowners and landscape managers for years. Some of the more common aphids include the green peach aphid, melon aphid, tuliptree aphid, giant bark aphid, white pine aphid, and rose aphid.
