To every thing there is a season. Eventually a beetle killing wasp or such will be along to balance it out.

One can't credibly speak of balances when they do not know the ratio of beetles to trees that would define a balance, nor do they have the means to estimate this ratio. They must rely on what science says about balance. Though by most anyone's estimation, enough trees killed to cover the size of the state of Washington can likely be defined as an unbalance. Science once knew just how many bark beetles per square area had to die to prevent an epidemic. Through sloth, Homo sapiens became a piss-poor steward of the earth, as bark-beetle clouds can now been detected on radar. Global warming increases bark beetle numbers. There are now too many bark beetles, and no one seems to be able to stop them. There was a time when they could have been stopped by humans. Alarmist? Nuts. Denial and ostrich imitations are more like it. Homo sapiens now lives most of its life in screenal space.

One cannot speak of balances when they think humans are the balancers when they are just another species headed for extinction like all the others, not because of global warming, but because to everything there is a season.

I bought some piece of furniture from China about 3 years back.. Carton was stuffed with larvae and eggs of who knows what.. Need to require everything get fumigated in customs...

Yes, the emerald ash borer's origins are suspicious, because it was originally described at Peking, China in 1886 or so. But the same genus of beetle, Agrilus., was brought into Sturgeon Bay, Wisconsin in a load of lumber from the Mediterranean in 1927. Nowhere in msm reports of the emerald ash borer was there mention of this fact.

When bark beetle videos show maps where the red colored parts means that 100% of the trees have been killed, it's hard to speak of balance.

While on the trail to discover the specific original article we seek for bark beetle control (British Columbia), we excerpt here from the historical literature as a review:

Whitney HS, et al, In Defense of the Concept of Direct Control of Mountain Pine Beetle Populations in Lodgepole Pine: Some Modern Approaches, Symposium Proceedings, Pullman, Washington, April 25-27, 1978
'....Modern approaches to the use of explosives, the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin, improvements in standing single tree burning, a mechanical debarker and microwave power are described.
....

Recently we began investigating new alternatives and approaches for use in direct control of the mountain pine beetle in the interior of British Columbia. We are convinced that prevention of population build-up of this beetle in susceptible high-value stands is a useful strategy and that tactics can be developed to achieve it. There is no proof that it does not work. Moreover, there is new evidence from two unreplicated 16 Ha (64-acre) plots of infested lodgepole pine that a combination of a pheromone with an insecticide and an aborticide can be used sequentially to reduce the spread of an infestation by as much as sixfold (Dyer 1978)


Bark Removal and Disruption by Firing 50-Grain Per Foot Detonating Cord on Lodgepole
(Describes wrapping the cord around the trunk with 20-cm spacings)
Some possibilities are being explored on the rationale that beetle broods produced above 8-10 m (26 to 33 ft) in standing lodgepole pine trees are not sufficient to sustain a growing population, and that ways and means can be devised for applying detonating cord up to this height without climbing the trees. In addition to meeting the general criteria for direct control, the versatility of this unique source of energy is attractive. There is a fire hazard in firing ordinary detonating cord but this can be reduced by using cord with no-flash properties. The main disadvantage in using explosives is the hazard in connection with accidental firing.

Use of Beauveria bassiana (Balsamo)as a Bioinsecticide
....In experiments in lab and greenhouse, more than 90 % of field-collected mountain pine beetles topically inoculated with B. bassiana spores became infected in 6 to 7 days. This essentially confirms Moore's (1973) findings in in vitro pathogenicity tests with the southern pine beetle (Dendroctonus frontalis Zimmerman) inoculated with B. bassiana. In greenhouse tests, new generation adult mountain pine beetles, caged with fresh pine bolts dusted with B. bassiana spores, picked up the spores and became diseased and died within a few days after penetrating the bolts. After 12 days there was 82 % mortality in the treatment groups and 30 % in controls.

Single Stand Tree Burning
....a minimum of 3 minutes raised the under-bark temperatures above 46 C (114.8 F) and resulted in death of all stages of the brood. In general, this treatment satisfied the guideline cited by Keen (1952) of maintaining fire until the edges of the bark flakes turned to white ash....Treated trees that had been only partially attacked or trees that had pitched out previous attacks survived the scorching but were invariably heavily attacked during subsequent flights, this corroborating the attractiveness of fire-scorched trees, either as a result of stress or a result of immediate effects such as those cited by Rust (1933).
....
Additional Alternatives for Direct Control
The self-climbing mechanical tree-pruning device known as the "tree monkey" could be modified to remove or possibly mangle bark, as well as cut off branches, as it travels up and down a tree stem. Such a machine, although fairly complex, perhaps heavy and useless on forked or very crooked trees, would do a thorough job in a matter of a few minutes on trees it could climb. There would be no need for men to climb or fell trees and no environmentally undesirable side effects.

Recent advances in application of microwave power and in portable electric generators suggest the possibility of micro-wave treating bark beetle broods in situ. An 8- 10-m hand-held antenna that could be moved in and among branches, where necessary, would suffice to apply microwave power directly to the infested bole. Unfortunately, this method is impractical in remote areas because of electrical power limitations However, experiments should be done to find out what effect lesser doses of microwave energy might have on growth, development or function of bark beetles in brood habitat, especially immature stages. In any case, microwave heating could be considered for direct control of brood logs from salvage logging operations arriving at mill sites.'

Oy.....just when you think you've seen everything from the climate obsessed, they come up with a new level of st00pid.....

"Climate change is increasing the bark beetle population... "

That's what keeps me coming back to this forum.....the mental cases putting it in a batting tee for you.

And the people scratch their heads as to why there is no interest in climate change action?!

Again....if these people had some real responsibilities in life, they wouldnt have time to worry about st00pid shit like bark beetles!
