Beneficial Insects: True Bugs, Erin W. Hodgson, Ron Patterson

All Current Publications

True bugs have piercing-sucking mouthparts and belong to the order Hemiptera and suborder Heteroptera. There are more than 38,000 species of true bugs, and are most closely related to aphids, cicadas, and leaf hoppers. Although some true bugs are considered pests, about one-third are predaceous. True bugs have forewings, or hemelytra, that cross over the back at rest, but sometimes the wings are reduced.

Beneficial Insects: Beetles, Erin W. Hodgson, Ron Patterson Nov 2007

Beneficial Insects: Beetles, Erin W. Hodgson, Ron Patterson

All Current Publications

There are many beneficial beetles in Utah besides lady beetles or ladybugs. Beetles can significantly reduce common insect and weed problems and in some cases eliminate the need for chemical control. Examples of beneficial beetles include: ground beetles, rove beetles, tiger beetles and tortoise beetles. Many of these beetles are native to Utah, while others have been purposely introduced to help control damage from exotic insect and weed pests.

Corn Silage Performance, 2006; Cache County, Utah, T. C. Griggs, C. E. Israelsen

All Current Publications

This report summarizes on-farm performance of irrigated silage corn hybrids at Benson (Cache County) in 2006. The site is at 4439 ft elevation and has a long-term average of 2800 corn growing degree days (50/86° F) per year. Hybrids were seeded with a six-row planter on May 10 at approximately 35,000 seeds/ac into Kidman fine sandy loam. Plots were six rows wide at 30-in row spacing by 1070 ft long in three randomized complete blocks.

Cranberry Girdler, Erin W. Hodgson, Alan H. Roe

All Current Publications

Cranberry girdler, Chrysoteuchia topiaria, can be found throughout the U.S., but is particularly damaging to turfgrass seed production areas in the Pacific Northwest. This insect was first detected in northern and northeastern Utah during the early 1980’s. Larvae prefer cool-season grasses, such as Kentucky bluegrass, bentgrass and fine-leaf fescues. In addition to causing significant damage to turfgrass, it is recorded as a pest of other grasses, cranberry, Douglas fir, and true firs.
