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

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

All Current Publications

Mantids refer to an entire predatory group of insects in the order Mantodea. The term “mantis” or “praying mantis” actually refers to a particular genus of mantids. Therefore, only some mantids belong to the genus Mantis. There are about 2,000 species of mantids worldwide and at least 20 species in the U.S. Two mantid species dominate Utah gardens: European mantid and Chinese mantid.

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.

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.

All Current Publications

Pear psylla (Cacopsylla pyricola), a western Europe native, is a very small sap-feeding insect and is considered the most serious insect pest of pear in the United States. Serious infestations can stunt, defoliate, and even kill trees. Psylla feeding produces copious amounts of sticky honeydew that can cause fruit russetting.

Cereal leaf beetle, Oulema melanopus, is a leaf beetle in the family Chrysomelidae. These beetles are native to Europe and have been considered pests of small grains since 1737. In 1962, cereal leaf beetle was first detected in the United States in a Michigan grain field. Since the 1960s, this insect has spread throughout much of the United States and Canada; now at least 30 states have confirmed cereal leaf beetle populations.

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.

Sod Webworms, Erin W. Hodgson, Alan H. Roe

All Current Publications

The term “sod webworm” refers to an insect complex of more than twenty different grass-infesting species. Adult sod webworms are pyralid moths, but are more commonly referred to as “snout moths” because their mouthparts are projected forward (Fig. 1). Sod webworms are distributed through the U.S., and at least seven different species occur in Utah (Table 1).

Armyworm And Cutworms In Turf, Erin W. Hodgson

All Current Publications

Armyworms and cutworms can be found all over the United States, with at least three species found in Utah. These insects belong to a large group of night-flying moths in the family Noctuidae. Although not new pests to turfgrass, armyworms and cutworms are often ignored, and plant health decline is confused with drought stress, fungal disease, or other insects.
