    Caselton Lowe, C. 2008. An examination of insect communities and their response to changes in vegetation structure with emphasis on Coleoptera and Hymenoptera in a sagebrush steppe habitat in south-central Idaho. Master

    Abstract:  A community of insects and it’s response to grazing were examined in asagebrush steppe habitat of south-central Idaho.  The study had fourobjectives: 1. to describe the diversity of insect orders, andHymenoptera (bees, ants, and wasps) and Coleoptera (beetles) families,2. to compare three inexpensive, simple trap types, 3. to determine ifgrazing, as practiced by Lava Lake Land and Livestock, had anyimmediate affect on vegetation and insect communities, and 4. toexamine how grazing-induced changes in vegetation structure affectinsect communities.  The study area consisted of six pastures, eachreceiving one of three treatments: no grazing, a light grazingtreatment, and a heavier grazing treatment.  Insect communities weresampled at 24 sampling stations, eight stations within each treatment. Vegetation cover and biomass were estimated at each of the 24 samplingstations.  A total of 41,533 insects representing 13 orders werecaptured.  Of these, 7,250 of the insects were Coleoptera from 28families and 18,716 of the insects Hymenoptera from 36 families.  Datademonstrated that the three trap types employed were useful andcomplementary for sampling insects in a sagebrush steppe habitat. Pasture-wide vegetation measurements estimated average sheep biomassutilization to be 4% and 11% for the light and heavier grazingtreatments, respectively.  No significant differences among treatmentswere found for the vegetation or insect analyses.  Evidence did notdemonstrate that changes in vegetation structure either from seasonalprogression or grazing had any major impact on the insect community.
