Posts about ant-aphid mutualism written by sleather An ant dairy maid coming to milk her aphids – their siphunculi and anuses are just visible if you look. These relationships are mainly mutualistic. An example of this type of relationship is between aphids and several ant species. The aphids provide honeydew to. Aphids and ants on plants are as interdependent as peanut butter and jelly. of ants, who actually “milk” the aphids for it by stroking their abdomen. The relationship between aphids and ants is symbiotic in that both receive.

Over time the resin hardens and becomes a substance known as copal. This can then find its way into the soil; the tree falls over or the copal becomes detached and falls to the round. Once in the soil, the copal has the chance, over several million years, to harden further still and eventually become resin. Any insect trapped in resin is perfectly preserved, ready for the intrepid palaeoentomologist to discover and name or entrepreneur to sell to curio collectors.

A very fine specimen with a very long stylet; presumably this fed on the trunk of trees. Photo from Ross Not all aphids in amber are as easy to identify as the two specimens above.

The example below is why I have such a great admiration for palaeoaphidologists. I am told that this is an aphid. I have written earlier about the close relationships that many aphids have with ants and it seems from the number of times ants and aphids have been found in close proximity in amber inclusions, that this association has been in existence for at least 73 million years especially with Germaraphis dryoides Heie, ; Perkovsky, Ant and aphid in amber.

Aphid in amber with nematode parasite Poinar, What can we learn from these amber inclusions? First, by comparing them with modern aphids, we can make inferences about their life styles.

As Ole Heie pointed out, aphids with clawed tarsi feet and long mouth parts are almost certainly not only to be tree dwellers, but ones that fed through the bark on the stems or trunks.

Aphids that live on the underside of leaves need neither of these adaptations.

The overwintering eggs that hatch in the spring result in females, called fundatrices stem mothers. Reproduction typically does not involve males parthenogenesis and results in live birth viviparity.

The Symbiotic Relationship Between Ants And Aphids

The young emerge from the mother soon after hatching. As the eggs begin to develop immediately after ovulation, an adult female can house developing female nymphs which already have parthenogenetically developing embryos inside them. This telescoping of generations enables aphids to increase in number with great rapidity.

The offspring resemble their parent in every way except size. Thus, a female's diet can affect the body size and birth rate of more than two generations daughters and granddaughters. For example, some species of cabbage aphids like Brevicoryne brassicae can produce up to 41 generations of females in a season.

Thus, one female hatched in spring can theoretically produce billions of descendants, were they all to survive. In autumn, aphids reproduce sexually and lay eggs.

Environmental factors such as change in photoperiod and temperatureor perhaps a lower food quantity or quality, causes females to parthenogenetically produce sexual females and males. The eggs survive the winter and hatch into winged alate or wingless females the following spring. This occurs in, for example, the life cycle of the rose aphid Macrosiphum rosaewhich may be considered typical of the family. However, in warm environments, such as in the tropics or in a greenhouseaphids may go on reproducing asexually for many years.

They pierce the vascular systems of plants to feed on their juices, extracting protein but excreting sugar, which their bodies don't need. This residue is called honeydew and many other insects, including ants, lap it up. To Ants, Aphids Are Livestock When an aphid-hunting ant comes upon a herd of his quarry, he returns to the nest, leaving a trail of "recruitment" pheromones for worker ants to follow to the source.

From then on, the aphids are effectively enslaved by the ants. First, they're drugged with a tranquilizing chemical excreted from the ants' feet, slowing down their speed of movement by about a third.

To make doubly sure the aphids don't get any ideas about taking off, ants may also bite off their wings or secrete chemicals that impair wing development. To "milk" the aphids, ants massage their abdomens with their antennae, stimulating the release of honeydew. And, if the ants want more dietary protein, they eat the aphids. Aphid Husbandry Ants control the reproductive capacities of aphids to boost numbers of the most useful while phasing out the least productive, mainly by eating them.
