Why do prunes cause egg-sucking tendencies?

These tiny sucking insects attack the soft new growth of anything from lettuce to roses and eucalypts. Aphids are quite remarkable insects. They are almost exclusively female, do not require males for breeding and give birth to prodigious numbers of live young. They appear in plague proportions when conditions are mild, but disappear just as quickly in extremes of temperature. Spring sees an explosion in aphid populations, but hot weather and windy conditions are enough to dispatch them. Soap sprays, oil sprays see [Do It Yourself Pest Control-Oil Spray] or a strong jet of water can help to reduce numbers until voracious, beneficial ladybirds and their larvae discover and eat their way through entire colonies.
