...that so much attention has been given to the brown-tailed moth, the elm-tree panther (or whatever it is,) and other pests in the Yard, why not rid it of that human pest called the insurance drummer? He stands around, enters Sever, and our very class-rooms in his impudence, he pounces on instructors and students, dreaded by all, a babbling symbol of the imminence of death. Can we not even in the privacy of our work-rooms eschew the cringing advances of this infernal nuisance? Is it not within the authority of our excellent "Yard Cops" to expel...
...preserve those trees which are still alive. A number of them were trimmed during the summer and the deadwood is now being removed from the remaining trees. The dead trees and decayed wood was found to afford breeding places for such pests as the bark beetle and the leopard moth and so the utmost care has been exercised in removing as much of this as possible...
...poor condition of the elm trees in and about the Yard has made radical changes necessary. The trees have been attacked by the leopard moth, which bores into the wood, making any attempt at their extermination practically impossible. Moreover, work on the subway and the sewerage system in Harvard square has been injurious to the trees, as much moisture is drained off, thus making them more susceptible to the attack of the moths...
Insecticides fail to reach either the leopard moth or bark-borer. And such a spraying as the trees got when attacked by the elm-leaf beetle may have something to do with the apparent absence of insect enemies of the two above-named species. For the spraying of the trees could have easily killed their parasites, which might have been lurking about on the trees at the time the spray- ing was done. And one thing that favors this theory is,--the leopard moth is worst in that part of the Yard which was the most carefully sprayed...
...work of determining the life histories of these insects is being carried on as speedily as conditions will permit. Plans are also being made to put out trap trees and electric light traps in the spring. Further it is hoped that parasites of the leopard moth can be procured from Europe. And it has already been tried and so far has resulted in failure, because the larvae are very hard to find during the winter...
