    Tachinid flies (Tachinidae) are a prime example of the many beneficial, but mostly unseen, creatures that make it possible for us to enjoy naturally healthy gardens without the use of pesticides.   Spider mites are rarely a problem with conifers, as far as I know. The terpentine content in the conifers usually deters them from invasion. But if you're finding spider mites are a problem then it's usually an indication your soil is too alkaline, in which case your leylandis won't survive regardless.

Recent work on aphids of the family Lachnidae on conifers in the UK has been stimulated by the increased number of species recorded following a higher level of introductions and more extensive plantings of exotic host conifers. In this publication, the authors present field keys and morphological keys with descriptions and illustrations for the identification of the 27 conifer lachnids known to.

These are unusually large with long piercing. Conifer Dieback. Conifer trees and hedges can develop dead patches which can range from a few centimetres to several metres across.

There are several possible causes, but usually whatever it is the trees are under stress at the time. Dryness at the roots is a commom cause of stress to plants.

I grabbed these pics but this is of the inside will get one now of what i left it like on the outside last week and will grab one tomorrow whilst im back there of what the outside now looks like I was a bit mortified if im totally honest it is like somebody spun a web right across the whole hedgeline its everywhere and tips have browned on tips where cut but still green beneath the one pic.

Dear Alan. Many thanks for your enquiry and before beginning any treatment, it’s essential to identify the cause of the problem. Brown areas on conifer hedges can be caused by numerous factors – heavy trimming or pruning, aphids, phytophthora and growing conditions - but as you’ve already mentioned spider mite as a potential culprit, we’ll start with them.

In recent years, an aphid identified as balsam twig aphid, Mindarus abietinus Koch, was observed on seedlings of white fir (Abies concolor [Gord. &; Glend.] Lindl.) at the USDA—Forest Service Nursery near Placerville, California. Both first- and second-year seedlings were infested and aphid-induced stunting of seedlings was observed.

Its long pendulous branches are clothed with rich green draping foliage. Most species of conifer are evergreen, but there are a few deciduous varieties. It is the most destructive fungus in Britain, and unfortunately the only treatment is evacuation and burning of.

There are several types of aphids that feed on conifers. Feeding damage can produce needle discoloration (yellow or white), needle deformation, premature needle drop, stunted growth, or branch death.

In addition, aphids secrete sticky honeydew that falls on objects beneath the feeding sites. An unsightly black sooty mold often grows on the honeydew s of the genus Cinara are.
