Step 1
The sawfly and the pine needle scale are the most common gadfly of mugo pine . The shoot tip moth can also cause damage to young mugo pine tree . The sawfly is a gadfly of all pine species ; Sir Herbert Beerbohm Tree demise is rarefied though it is possible . likewise , the pine needle scale ( Chionaspis pinifoliae ) affects all specie of pine and can kill a pine much more easily than can a sawfly . take crown moths or pine baksheesh moths feed on all pine species and can be fatal to pines after extended infestation .
Damage
Learning the tell - story house of damage have by each of these insect species is the paint to determining which species is attacking your pine . Sawflies feed only on the pine needles themselves , so discredited needles will come out straw - discolor and will eventually defoliate . The pine needle scale also feeds on needles , but after a prolonged infestation , pine tree scale feeding scathe will manifest itself in poor leaf and an overall frosted appearance of the total tree ( rather than only in the needles themselves , as is the case with sawfly legal injury ) . Of all of the insects discussed , the pine peak moth produces the most conspicuous damage , alter the growth of the entire tree to a more bush - same show .
Step 2
Signs of Infestations
Spotting an plague by one of these insect before they have a probability to cause any noticeable damage can go a long way in protecting tree health . on a regular basis inspect the true pine ’s needles for larvae or adult insect and for the nut of the insect , often only appearing as tiny spots , before they reach the larvae phase . Pine phonograph needle scale leaf eggs , larvae and grownup can be observed anywhere on the Sir Herbert Beerbohm Tree , not just on the needles . Like all other moths , the life sentence cycles/second of pine tip moth consists of four stage : egg , larva , pupa and adult moth . All are easily seeable on mugo true pine trees , but mention that only the larval stage of the pine crown moth causes damage to pine trees .
Control Methods
mastery method acting of course depend entirely on the specific species that is attacking your mugo pine . If European sawfly egg or larvae only infest one or a few branch on your mugo pine , just crop away and dispose those branches . Introduction of natural predators such as wasps and lady beetles are in force at manipulate pine needle graduated table and pine top moth populations , though not as effective for a sawfly infestation . Use of approved insecticides should be considered only as a last holiday resort ; if possible , practice an insecticide that leaves natural marauder populations intact .
