    There are different systems of feeding cattle in animal husbandry, which may have different advantages and cattle in the US have a fodder that is composed of at least some forage (grass, legumes, or silage).In fact, most beef cattle are raised on pasture from birth in the spring until autumn (7 to 9 months). For pastured animals, grass is usually the forage .   Black grass bug, a native rangeland insect, is responsible for this crop injury. Black grass bugs have caused considerable damage to certain western range .

      The western conifer-seed bug (Leptoglossus occidentalis), a plant-eating insect, has been documented to have bitten a human, though researchers consider the bite to have been a chance occurrence and not the result of the insect targeting the human.(Photo credit: Joseph Berger, ). Many of these insects feed on grain crops as well as other native and introduced grasses.

The host range of black grass bugs is quite broad. They feed primarily on grasses, but will feed on some broadleaf plants in the absence of grasses. There are definite host preferences, with wheatgrasses being among the most preferred species.

BOISE, Idaho — Bromus species – such as cheatgrass – are exotic annual grasses that have become the dominant annual grasses in the western hemisphere. Adults feed by chewing holes in grass stems, but cause no significant damage to the turf. Adult females insert eggs into the feeding holes they create (Fig.

Larvae bore inside the stems until they deplete the resources within (Fig. By mid-June, larger larvae begin feeding on plant crownsMissing: western ranges. west, and is the Wyoming state grass.

Chinch bugs are sap-sucking insects that feed by sucking on grass blades. While feeding, chinch bugs secrete an anticoagulant that causes grass to stop absorbing water.

Insects are not a common cause of residential lawn damage in California, but certain species may occasionally damage or kill turfgrass. Insect feeding can cause grass to turn yellow or brown or die, especially if the grass is already stressed.

line drawings. Most phytophagous insects are host restricted (Bernays and Graham ), and careful fieldwork on grass-feeding species previously regarded as polyphagous often reveals a narrower host range (e.g., Nickel ).

Grass feeders can be generalists, developing on species of several subfamilies, or specialists on a particular subfamily (Whitcomb et.
