Here are some of the common results of an aphid infestation: When aphids devour the liquids from the plants, they also become carriers of any viruses the host plant may have. When the aphid moves to a different plant to begin a new colony, these viruses can be transmitted from one plant to another by the aphid. Aphid feeding led to significant increase in RNA accumulation for 126 different genes. Different patterns of deregulation were observed, including transitory or stable induction 3 or 7 days after infestation. The genes affected belonged to various functional categories and were induced systemically in the phloem after infestation.Mix 3 teaspoons of dish soap with 1 quart of water.
