ash whitefly Siphoninus phillyreae


The ash whitefly, Siphoninus phillyreae , is a pest of numerous ornamental and fruit crops, including citrus. It causes severe damage to pear and apple in Europe. Most ash whiteflies in California were found on pomegranate, ash tree, pear, apple, loquat and citrus. Heavy infestations cause leaf wilt, early leaf drop and smaller fruit
In the United States, ash whitefly was first collected in Los Angeles County, California in 1988, and then spread to other counties. It was later discovered in Arizona, Nevada and New Mexico. It appeared in Raleigh, North Carolina in 1993. It is also reported from Arizona, Georgia, Nevada, New Mexico, South Carolina and Texas. A successful biological control program using a parasitic wasp reduced infestations to undetectable levels (western states) or possibly eliminated the infestion (North Carolina). In 2010, it was discovered in central (Lake Buena Vista) and northwestern (Panama City) Florida (Stocks and Hodges 2010)


The adult appears much like a typical whitefly with a light dusting of white wax. Depending on temperature, females live from 30 to 60 days, while males live an average of nine days. This rapid development time, without the presence of the parasitiod, initially produced numerous generations per year in California, whereas only two to three generations were reported in Egypt. Plus, the ability of all life stages to overwinter on non-deciduous hosts allows a rapid build-up in population at the start of the season (Stocks and Hodges 2010). Winged females lays eggs on the underside of the leaves. When the nymphs emerge, they rarely move far and feed on the plant sap until pupation (Gillespie 2000).


Pupa: On first observation, the pupal case appears similar to the white armor of a male snow scale. Closer observation with a hand lens reveals a whitefly pupal case with two longitudinal tufts of white wax. The vasiform orifice is surrounded by dark brown derma (inner, thicker layer of the cuticle), with the anal area appearing as a dark brown spot. Lateral areas of the pupal case are light beige. Depending on the age, lesser or greater amounts of white wax will be present. The dorsal surface has 40 to 50 long glassy tubercles similar to the cornicles found on aphids. These tubercular structures produce a droplet of glassy wax and this gives the pupal case an unusual appearance. The longitudinal white tufts of wax obscure some glassy tubercles The pupal case size is 0.8 to 1.0 mm long by 0.55 to 0.7 mm wide and is tan or beige in color

Insect pests can and do injure the Palo Verde and other desert trees. These pests can damage leaves, twigs, branches, trunks and roots. The most dangerous is the root borer
The Palo Verde Borers are root borers and are rarely seen above ground. Adults are 4" to 6" long with antennae nearly as long as their bodies. Adults are active July through October. Immature larvae feed on roots of Mexican Palo Verde and other non-native trees. Larvae spend up to three years underground feeding on roots. Over a 7 to 10 year period Palo Verde Borers will gradually kill a tree. Most adult borer females lay eggs from spring through summer.
Another class of Insect that usually attacks stressed or damaged desert trees like the Palo Verde are Flatheaded Borers
Flatheaded Borers most commonly invade sunburned or otherwise damaged areas along the trunks and branches of trees.
Olive-gray adults lay eggs under the bark of damaged areas. The larvae are cream colored and legless and mature to 1 1/2" long.
The maturing larvae feed on dead wood and make small tunnels filled with what appears to be sawdust. This damage occurs beneath the bark and can go unnoticed for long periods.
Another borer that attacks the Polo Verde is the Round headed Borers. This is what the larvae of the Round headed Borers look like.
Another type of insects is the insects that attack the foliage of desert trees. These include: Acacia whitefly, aphids, and psyllids
Acacia White Fly actually appears dark gray or black because of a large dark spot on the body. These insects reproduce rapidly and cause significant leaf loss.
Aphids are a common and wide spread plant pest that can attack desert species. Aphids are restricted to the succulent new growth on the tips of twigs of desert trees. Aphids reproduce rapidly and can quickly kill small twigs and deposit honey dew (a clear, sticky material excreted by aphids that blackens leaves and twigs).
This is a psyllid, Psyllids feed by scraping at the undersides of leaves giving the leaves a blotchy, yellowing appearance.
Psyllids suck plant juices and produce honeydew, sometimes in crystallized form, on which blackish sooty mold grows. Abundant psyllid infestation can cause defoliate and reduce plant growth.

The tree you're looking at is called a Western Myall. The Western Myall is a drought tolerant Australian shrub to small tree with downward growing drooping silvery-grey 1 to 5 inch long phyllodes. It is a slow growing, long lived, handsome tree- adapted to hot, arid regions. Showy yellow, ball flowers appear in clusters during the springtime.
Like most native trees this tree needs little if any fertilization. However, sometimes they have problems with insects. To check your trees, look for holes in the bark or damage to the leaves. All acacias need regular proper trimming to maintain their beauty, and lessen the possibility of limbs breaking.
This is particularly true in the monsoon season - when the winds are both strong and wet. We can help you with any of these concerns just give us a call at 480 969 8808.

How much water do trees need in the summer?
The single most important thing you can do to keep your trees healthy is to make sure they get enough water. 'How much water is enough?' seems like an easy question to answer, however, assessing how much water your tree really needs is not an easy answer to come by.
Trees very in their water requirements. Some trees, like Olives or Mesquites, are drought resistant; while others need more water to stay healthy. Also, the amount of water a tree needs to stay healthy is dependant on its location, size and general health.
To complicate matters more, we are currently in a drought in one of the hottest places on the planet, so the tree will need more water, more often than it would in a time of normal rain.
Fortunately, there are easy ways to determine if your trees are getting enough water.
Tree leaves expel water as part of their normal function. Feel the leaves in the mornings. If you slide a leaf between your fingers and feel slight moisture, the tree is probably getting enough water.
Take a good look at your tree, especially the top and the outer leaves.
Those parts are at the edge of the plant's water transport system, and will dry out first if something is wrong. Do they appear dry or dead, or do they appear green and healthy? If they don't appear healthy, then in most cases it's advisable to increase your watering.
check the ground
After the tree has been watered, check the ground by pressing a long screwdriver into the watered soil around the tree. Is the ground moist under the canopy, at least 12 inches down? If not, you're not watering long enough for that cycle.
Use common sense. Ask yourself, 'how much water from rainfall did this type of tree get in its' natural place of origin?' You can be sure it will need more here, unless it is a local native tree.
If your tree is a local native tree, you can get a good starting point for water requirements at The Arid Zone Website.
Keep steps 1 through 4 in mind, and adjust the watering up when
necessary, especially in the summer.

Pruning in Mesa AZ (480) 969-8808 Warners How Much To Water

 

 


When attempting to keep trees healthy in an urban setting it is helpful to first look at a more ideal environment like the forest.

In the forest, trees live in a supportive community of life.

The members of that community interact in ways we are just beginning to understand.

Insects and microscopic animals eat and digest the living soil again and again, creating humus - which in turn helps the soil retain moisture, and encourages the formation of more nutrient rich soil.

Mycorrhizal Fungi live in and around the roots, serving as a secondary root system, extending far out into the soil

This friendly fungus extracts mineral elements and water from soil for their host plant, and in return they live off a small amount of the roots sugar.

One of the many beneficial things that Mycorrhizal Fungi do is release antibiotics into the tree's root system.

This built-in shot of penicillin helps the tree to combat bacteria.

Humus, rich in plant nutrients binds to the Mycorrhizal Fungi, which in turn passes the nutrients off to the tree's roots.

The forest also offers protection from the sun

Just like our skin, bark develops differently in the sun then it does in the shade.

Shade bark can burn, and die if exposed to the sun. I see this often here in Ash and Citrus trees.

The forest provides trees with protection from disease

The large, the small, the microscopic -- the plants, the birds, and the insect -- they all usually maintain a balance.

This balance prevents any one type of life, from gaining the upper hand

For instance, tree roots reach out and graft with other roots, forming large living networks.

This scientific fact has been incorporated into recent movies like avatar, but in the forest it's real.

These root networks allow trees to warn each other of insect threats

This allows neighboring trees to prepare, by manufacturing chemicals in there bark, for the coming threat.

In an urban environment trees have none of these advantages.

And there are additional challenges that trees face, here in the Valley of the Sun

Chief among those dangers are incorrect information about watering - repeated over an over - until it becomes institutionalized

For instance, the fact that commercial citrus groves, are flooded twice a month in the summer, with massive amounts of water - water that reaches from one trunk to another, and leaves the ground muddy for days - some how this gets translated into a twenty minute shot of water from a itty bitty little rubber hose, once every two weeks

That's just nuts, but still the tree usually manages to live, somehow.

Just as harmful are tree trimming practices commonly used here daily. Again usually the trees survive the abuse, but just barely.

I could go on, but let me wrap this up by touching on four common problems I encounter, on a weekly bases.

First, there are periodic outbreaks of harmful insects, like the wooly aphid infestation of ash trees, and the problems citrus trees now face from spider mites

Second, almost all Queen Palms are infected with an airborne fungus that causes their fronds to wither. Left untreated, many Queen Palms with this disease will eventually die.

Third, the Aleppo Pines are sometimes infected with a mite that causes the needles to die back, and other pine spices are infected with various mites and aphids.

Forth, Citrus trees often have a fungus that causes the bark to split and ooze sap - eventually leading to branch dieback and sometimes early tree death

We can help with all of these conditions and many more.
