Book excerpt: Excerpt from Montana Insect Pests for 1931 and 1932: The Twenty-Fourth Report of the State of Entomologist of Montana More widespread infestations of the pale western cutworm were experienced in grain in 1932 than in any season since 1921. Ex tensive crop damage resulted in most of the northern part of Valley County, in the Judith Basin, in western Fergus County, and in western Gallatin County. Light, scattering infestations were recorded from many other sections. A few thousand acres of grain, together with a small acreage of corn, cultivated mustard, and flax, were completely destroyed by the cutw'orms, and reports show that acres of crop were noticeably damaged. (see figure Favorable moisture conditions early in the season enabled grain to get such a start that light or moderate infestations of the cut worm did not completely take the crops in most instances.

Book excerpt: Excerpt from Montana Insects Pests, 1947 and 1948: Thirty-Second Report of the State Entomologist The entomological outlook for Montana presents a number of ramifications which have not been previously stressed. Our insect problems have increased in the last decade and the possibility of further. Serious situations arising is almost certain. During the last few years, we have had infestations of a number of insects new to the state. Likewise, some native insects that have not previously been pests have caused considerable damage to agricultural crops. It had been predicted by earlier workers that two of these new insects, the alfalfa weevil and the differential grasshopper, could not become established in Montana because of our ecological conditions. At the present time both of these insects have become serious pests. The differential grasshopper was first found in Dawson County in 1932. Since that time it has spread over much of the eastern and southern parts of Montana and is now found in economically important numbers as far west as Yellow stone and Big Horn counties. The alfalfa weevil was first 'observed in 1938 and has been a serious pest to alfalfa in Southeastern Montana since 1945. It has spread every year and at the present time it is as far north and east as Terry and as far west as Reed Point. This pest has become so serious in some sections that it has threatened the alfalfa seed and feed growing industries. It was assumed by many of the early workers that climatic factors were primarily responsible for limiting the distribution of many of these pests. It is apparent from the above examples that the ability of an insect to adapt itself cannot be overlooked in predicting the limits of its geographic distribution. The wheat stem sawfly, which is a native insect of Montana, did not become important economically until 1941. Since that time this insect has become one of our most serious pests of spring and winter wheat, at present confining itself largely to the northern part of the state.

Book excerpt: Excerpt from Montana Insect Pests for 1935 and 1936: The Twenty-Sixth Report of the State Entomologist of Montana Mormon crickets have been on the increase in Montana since 1931. In that year but a few hundred acres in southern Montana were infested. Today the overwintering eggs are in the soil to such an extent that over one million acres will be badly infested next spring and not long after hatching occurs the march of the cricket armies will begin. Sixteen counties are vitally concerned with this problem and two or three others to a less serious extent. In addition, acres on the Tongue River and Crow Indian Reservation will be infested in 1937 unless a vigorous campaign of suppression is started early in the season.
