“…E. ochrogaster was not collected in the pheromone or bait traps cited above, but it may not respond to those attractants. Large numbers have been observed in the Yakima Valley in the past (Klostermeyer 1952, Tamaki et al 1975). Because we did not Þnd any E. ochrogaster larvae on the ground or on vines, it seems that populations were either extremely low or absent during the time of sampling.…”

The major grape (Vitis spp.)-growing areas of Washington were surveyed during 2003–2007 to determine the cutworm species present as larvae in vineyards during spring when grape buds and young shoots were vulnerable to cutworm (Lepidoptera: Noctuidae) damage. We sampled vineyard floors during daytime, vines at night because cutworms are active at night, and vines during the day. In total, 1,003 larvae were collected and 650 were reared to adults and identified. Twenty-five species were found: 22 on the ground, eight on vines at night, and two on vines during the day. Almost 75% of the cutworms on vines at night were Abagrotis orbis (Grote) and 19% were Agrotis vetusta Walker. The spotted cutworm, Xestia c-nigrum (L.), and the redbacked cutworm, Euxoa ochrogaster (Guenée), were reported previously to be the major cutworm pests of grapes in Washington, but only four X. c-nigrum and no E. ochrogaster were collected. Abagrotis orbis larvae were collected on grapes at night from mid-March to late April. Adults emerged in the laboratory in mid-May, and they were present during the summer. Agrotis vetusta larvae were collected on grapes from 1 to 30 April. This species had a long prepupal period during the summer, followed by a pupal stadium of ≈3 wk. Mean adult emergence was in early August. Both species were univoltine, with mating and egg laying during the fall followed by overwintering as small larvae.

“…This larva lives among root systems and in foliage at ground level. The importance of this cutworm in the summer diet may be of economic significance since crop and conifer seedling depredations have been attributed to cutworms of this genus (Whelan 1935;Fowells 1940;Klostermeyer 1952). Scarabaeid and carabid beetles, coleopterous larvae, grasshoppers ( H ippiscus sp.…”

Effects of Range Treatment With 2,4-D on Food Habits of Rodents

The food habits of rodents inhabiting shrub grass and perennial forb ranges in western Colorado were investigated to determine the kinds and proportions of foods eaten, the effects of range treatment with 2,4—D on food habits, and the degree of competition for food among rodents inhabiting these ranges. Treated and control areas at each site were trapped periodically and estimates were made of plant coverage. A part of the stomach contents of each rodent was mounted on a slide and was examined with microscopes. The volume in percent of each food item was estimated and recorded. Deer mice exhibited a seasonal variation in diet. Their winter food was primarily seeds whereas arthropods made up a large part of the diet during the summer months. Cutworms comprised almost one—half of the food ingested during June. Male and female deer mice showed no difference in diet, but the diet of deer mice varied with age group. fugi were found in the stomachs of rodents, particularly during the fall months. Deer mice occasionally ingested parts of small mammals. Grass seeds comprised a larger proportion and forb and shrub seeds a smaller proportion of the diet of deer mice inhabiting areas treated with 2,4—D than that for untreated areas. The availability of these food items appeared to be responsible for these observed differences in diet. Least chipmunks ate a variety of arthropods, seeds, and leaves, and, like the deer mouse, exhibited seasonal variation in diet. Although there was no significant difference in diets on treated and control areas, the influence of the availability of certain seeds was evident. Range treatment with 2,4—D had no effect on the diet of montane voles. Leaves and stems of forbs and shrubs comprised a large part of the summer diet on both treated and control areas on Grand Mesa. Differences in diet with sex and age were observed. The greater abundance of montane voles on treated areas appears to be due to an increase in grass cover and not to an increase in available food. No competition for food was observed among deer mice, least chipmunks, and montane voles at the population levels sampled in this study.

“…Poisoned bran bait, rvhich until 1951 was the material most frequently used fof control, was not entirely dependable, nor were surface applications of chlorinated h}'drocarbons (5,7,8) effective under all conditions. Some of the variation was no doubt due to the generzrlly known fact that surface treatments are most effective on moist soil during warm evenings (1,8).…”

Emulsions of dieldrin, aldrin, isodrin, toxaphene and chlordane applied to the soil surface and incorporated to a depth of about 4 inches proved highly effective in controlling the red-back cutworm, Euxoa ochrogaster (Guen.) when tested in asparagus fields in the interior of British Columbia in the summer of 1953 and 1954. In 1953 aldrin emulsion mixed with the soil was much more effective than when it was left on the soil surface, Bran bait containing paris green, although giving fairly satisfactory control, was less effective and slower in action than the emulsions. In 1952, dieldrin, aldrin, and isodrin dusts, applied to the soil surface, were superior to and faster in action than bran baits containing aldrin or endrin; all of the 1952 treatments were apparently slower in action in dry soil than in relatively moist soil. A survey of asparagus fields treated by growers in 1953 but not in 1954 indicated that aldrin emulsion, mixed with the soil at about 4 lb. of toxicant per acre, protects asparagus for at least two years.
