THE CITRUS LEAF MINER HAS FOUR LIFE STAGES

 

 

WHITEFLIES IN TEMP AZ

Hello this is Warner with Warner’s tree surgery and today I’m going to be talking about the Asian citrus leaf miner.

The Asian citrus leaf minor arrived in Florida approximately 14 years ago from Australia it originated in Vietnam and was first noticed in Mesa Arizona about 10 years ago.

When I first arrived in Arizona it had no natural predators. This is significant because most insects that feed on citrus trees have other insects to keep them in check.

I have learned from personal observation that it takes approximately five years for a citrus tree to become depleted of the stored energy in it's system. A citrus tree will store sugars oils and enzymes in the roots the trunk and its branches. The leaves produce energy to the process of photosynthesis in the form of sugars which are passed to the mitochondria which produces ATP.

The ATP is used by the DNA of the leaves to produce enzymes oils and starches that are used by the tree.

When a citrus tree begins to blossom it uses all of the energy that is produced by the leaves and draws on the stored energy.

It is only when the fruit is completely ripe which is usually in December that the tree restocks the energy that was used in the production of the fruit.

Normally this works well, but if a tree has its energy production reduced by either long periods of inadequate fertilization, or over pruning, or some other process that interferes with photosynthesis the reserves become depleted. When this happens all kinds of things start to go wrong.

The naturally occurring insecticides in the skin of the fruit vanishes. The oil on the surface of the leaves which protects it from insect damage also is depleted.

In the case of the Asian citrus leaf minor because it has no natural predators speak of the reserves are gradually depleted in citrus trees. And when that happens not only are the leaves more vulnerable to other insects but the roots of the trees become susceptible to soil born fungus.

I made the video on this page with the program that allowed me to create an animated script I don’t remember the name of the program but apparently I made it around 2013. I made a few other videos with the same program and I’m going to include them on this page this particular video has received over 3000 views on one of my YouTube channels.

There are currently four insects that seriously damage citrus trees two of them are only a problem in orchards because the virus and bacteria that they carry only lives for a short time in the insects. The other two are the Asian citrus leaf minor and the ash fly. The Asian citrus leaf minor was here first and while it is not as dangerous as the ash fly is been slowly depleting the energy reserves of almost every citrus tree in Maricopa County.

I have included on this page videos that explain the problem with the leaf minor and the ash fly along with the other animated videos that I produced. After watching these videos if you’ve decided that you’ve got a problem with you citrus trees give us a call and I can come out look at your trees.
