The United States Bureau of Entomology have successfully controlled 

 serious outbreaks of destructive Bark-beetles in several of the western states. 

 They have proved that the destructive Bark-beetles can be controlled, when 

 taken in time, and often at little expense; and have perfected methods of control. 

 Their publications, chiefly those by Dr. A. D. Hopkins, will be of great assistance 

 to us in the control of the same or allied species in British Columbia, and have 

 helped to settle doubtful points in connection with the life-history of several of 

 our species. 



GENERAL REVIEW OF FOREST INSECT CONDITIONS. 



THE LOWER COAST AND ISLAND. The Lower Coast, from Seymour Narrows 

 south, and the lower two-thirds of the Island, were included in the survey. 

 There were many destructive forest insects in this region; but no extensive 

 outbreaks of Bark-beetles, comparable to that in the bull pine of the Interior. 



The Sitka spruce is attacked and killed by a destructive Bark-beetle and 

 the western white pine is attacked and killed by the Mountain Pine Bark- 

 beetle. Any valuable stands of spruce and pine in this region should be watched 

 for outbreaks by these beetles, and the necessary control measures applied in 

 time to prevent serious injury. 



The Douglas fir, throughout this region, appears on the whole to be in fine 

 condition. A moderate number of ringshaken trees occur locally on the ridges, 

 and more or less injury by ground rot and shelf-fungi (conchs) was noticed. 

 The fungi collected have been referred to the Dominion Botanist. 



The Douglas Fir Beetle was found killing green timber in small amount 

 at Cowitchan Lake, and near Campbell River. 



Beetles of the genera (Hylesinus) and Eccoptogaster were found in several 

 places killing balsam fir, and hemlock. 



The Sitka Spruce Gall Aphis is causing serious injury, in places, to isolated 

 trees, and to isolated clumps and small areas of spruce. There is a very serious 

 infestation in Stanley park, Vancouver, and in the environs of the city. 



The Vancouver Island Oak Looper, a small caterpillar, has caused serious 

 injury to oaks on Vancouver island. 



The Western Hemlock Looper, an allied species, has apparently killed 

 numbers of hemlocks in Stanley park, and has very seriously injured many 

 others. 



Caterpillars were found in places destroying large numbers of cones of the 

 Douglas fir. 



The Larger Wood-borers and Ambrosia-beetles cause considerable injury 

 to fire-killed timber and injured trees, and to logs left in the woods over summer. 



THE INTERIOR: The southern portion of the interior, from the Railway 

 Belt south to the boundary, harbours a large number of destructive forest 

 insects. Bark-beetles of several species are specially injurious. They have 

 killed large quantities of bull pine, western white pine, and lodgepole pine, 

 and lesser amounts of spruce, Douglas fir and larch. In several places the 

 outbreaks by these beetles are so serious that vigorous control measures will 

 be required to prevent extensive loss. The injuries to Engelmann's spruce and 

 western larch will be discussed in later publications. 



Twig-boring Bark-beetles and twig-girdling caterpillars are particularly 

 common on the bull pine. Usually such injury is of little importance; but in 

 places, numbers of trees were being killed in this way this summer. An inter- 

 esting outbreak occurs between Okanagan Landing and Fairview. 



The Pissodes Beetles, spruce and pine weevils, are abundant locally, 

 destroying the terminal shoots of young growth. No very serious outbreaks 

 were located last summer.
