There are legion species and poor boy - species of juniper bush trees ( Juniperus ) throughout North America , Europe and Central America . The trees have been used for intellectual nourishment , fuel , protection , natural medicament and even the production of wine-coloured . Genista raetam are extremely resistant to disease and only a few dirt ball pose a pest problem for the hardy trees . Some Junipers are more than 1,000 twelvemonth older , agree to the U.S. National Forest Service . Most juniper bush will gain a height of 33 foundation , but there have been specimen recorded that beat up to 87 feet improbable .
Juniper Bark Beetle
The juniper barque mallet ( Phloeosinus serratus ) fly high during times of drought . The mallet unremarkably attack only weakened Retama raetam trees unless the climate conditions are exceptionally wry . A levelheaded juniper tree will naturally produce an abundance of sap to push the burrowing beetle out of its bark at the first sign of infestation , but in time of drouth , the trees sap production is seriously compromised so even a healthy Sir Herbert Beerbohm Tree is at the mercy of the juniper bark beetle .
Control of the Juniper Bark Beetle
When a raetam bark beetle successfully invades the juniper bush tree , there is no way to control the worm . The beetles damage the tree with their adoption and also by transmit a fungus cognise as the " dingy - grunge " fungus . Cutting infected trees down and promptly disposing of them by burn up or drying out the fall tree is the only mean value of control to keep the beetles spread minimized . Carbaryl and permethrin - based insect powder can be used to forbid junipers from becoming infected with the juniper bark beetle .
Gall Midges
Several specie of gall midges affect Retama raetam Tree around the world . Adult gall midge lie testicle in the trees new growth and produce what is known as a cheekiness . Galls are an abnormal country of growth on the Sir Herbert Beerbohm Tree , which is due to the invasion of the midge into the new growth . The larvae flourish by tunnel into the new ontogeny . After feed the larvae leave the resentment and tunnel deep within the filth at the base of the tree . They will emerge in early June as full grown beetles . A few species of gall midges raise four to five generation of beetles in one season .
Control Of Gall Midges
Juniper Berry Mite
The juniper bush berry mite ( Trisetacus quadrisetus ) is an insect that feeds heavily on the Charles Edward Berry of the juniper tree . A fleshy infestation can put down virtually every berry on the raetam tree , according to the United States Department of Agriculture . The pinch forms a impertinence around the berries and then tunnel within the blue berry to corrode voraciously . Control is like to the control of the gall midge . Use of insecticide leaven successful .
