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.
Getting rid of aphids can be quite the challenge. If you find just a few on your plants knock them off with a stream of water from the hose. Be careful not to damage the plant with a heavy stream of water. You can also spray the aphids with a mixture of warm soapy water in a spray bottle.
