    The females lay their eggs deep in the soil, 2 to 6 inches below the groundline. Oviposition begins about a week after mating and may continue over several weeks during spring and summer. The larvae, or white grubs, hatch in 2 to 3 weeks and begin feeding on organic matter in the soil. Soon, however, they feed on the tender roots of nearby. In general, White Grubs have creamy-white to gray-colored bodies, brown heads and six distinct legs. You can usually find them curled up in a C-shaped position in your lawn's soil. The easiest way to identify the different types of White Grubs is to examine the raster patterns on these lawn pests.

    Control of White Grub Infestations in Lawns. An understanding of the cycle of the White Grub is important before beginning your control measures. Without a plan or control program the numbers of white grubs in lawns will increase as will their damage to lawns, turf grass, golf courses and other grasses in areas such as pastures or graze lands. Ohio White Grub Raster Patterns—Correct identification of white grub species is important in determining management strategies and timing of controls. The raster pattern is the arrangement of bristles and hairs on the underside of the tip of the abdomen. A 10x hand lens is needed to see this pattern on most mature white grubs. A microscope may be necessary to view smaller grubs or the.

    Grubs (soil-inhabiting) White grubs may be the most damaging turf insect pests in the United States. According to the U.S. Department of Agriculture, Japanese beetle grubs alone cause an estimated $ million in damage each year— $78 million for control costs and an additional $ million for replacement of damaged turf. Larvae of the genus Phyllophaga are commonly known as white grubs due to their body color (Ritcher, ), whereas adults are referred to as May or June beetles due to their flight period. Several species of Phyllophaga are identified as major agri- cultural pests, and in the northeastern United States and Canada P. anxia has been recognized as.

White Grubs and Their Allies: A Study of North American Scarabaeoid Larvae Ritcher, Paul O. Published by Oregon State University Press, Corvallis ().

Adults of white grubs and related forms have lam- ellate antennae and are sluggish beetles ranging from one -eighth inch to six inches in length. Many are an inconspicuous brown or black color ; but some White grubs and their allies book bright green, blue, or yellow, with metallic lustre.

Many species are nocturnal. Additional Physical Format: Online version: Ritcher, Paul O. White grubs and their allies. Corvallis, Oregon State University Press [] (OCoLC) The whitish, soil-dwelling larvae of scarab beetle species are called white grubs.

Traditionally, white grubs were considered to be members of the genus Phyllophaga, but increasingly the larvae of other members of the family Scarabaeidae such as Anomala, Aphodius, Ataenius, Cyclocephala, Exomala, Polyphylla, Popilla, Rhizotrogus, and other are included in this general term because they have a very.

White Grubs. White grubs is a general name for the larval stage of beetles in the family Scarabaeidae, order Coleoptera, that feed on the roots of turf.

All species of scarab beetles have larvae that are C-shaped and vary in size depending on the species and larval age (instar).

You need grubs about 8 to 10 grubs per square foot before you would really achieve damage. To prevent grubs, use residual lifespan of insecticides that we apply to the turf.

Even though we know that most white grub populations arrive in July or August, some of these insecticides have residual activities of 3 to 4 months, and so we can apply them earlier to prevent those grub infestations.

White Grub’s Habitat. White grubs are common in places where it is sunny. They dwell on the soil, which is why they commonly affect turfgrass.

They feed on the roots of their host plant, which is where the damage starts. Identifying White Grub’s Damage Plants Affected. Among others, turfgrass is perhaps the most common host for white grubs.

White Grubs (Lawn Grubs) are the larval stage of scarab beetles, and they develop under your turf, feeding on the roots of the grass. This feeding causes damage to your lawn, making white grubs a troublesome lawn pest. Learning how to identify white grubs will help you to control white grubs. White Grubs and Their Allies.

Oregon State University Press, Corvallis, OR. Phyllophaga and Related Species (Coleoptera: Scarabaeidae) Collected in Black-light Traps in Alabama Pastures. Grubs are milky white with a brownish head. They typically curl into a "C" shape when disturbed.

Depending on species they may have a 1-year or a 3-year life cycle. Annual white grubs (larvae of masked chafer beetles or Japanese beetles) begin their life cycle in mid- to late summer, grow quickly, and do most of their feeding in late summer. The larvae of many scarab beetle species are often collectively referred to as white grubs – Phyllophaga, several species (spp.); Coleoptera: Scarabaeidae – and can be found in soil, decaying wood and manure.

In Minnesota, larvae of the genus Phyllophaga (Harris, Figure 1) are the scarabs most often associated with damage to corn root systems. These are the true white grubs. The adults. White Grubs, Phyllophaga spp.

by Bruce Wenning White grubs are insect pests of home lawns, athletic fields, parks, gardens and anywhere their preferred hosts grow. They live in soil, are C-shaped, have six legs, chewing mouthparts, and feed on turfgrass roots and the roots of other plants.

Lawns that are attacked by these pests show poor vigor, thin turf. Abstract. Chiral capillary gas chromatographic–electroantennographic detection (GC-EAD) analysis indicates that L-valine and L-isoleucine methyl esters are the major sex pheromone components released by females of the cranberry white grub, Phyllophaga anxia (LeConte).

The GC retention times and GC-mass spectrometry of the two natural compounds were identical to those of authentic by: White grub problems in were most prevalent in east-central, central, southwestern, and northwestern Illinois, but growers elsewhere had their fair share of grubs. Before the pace of corn planting becomes frenzied, now is a good time to review what we know and what we hope to learn about white grubs in Soft, white bodied forms, like the white grub and rootworm, live in protected places while leaf feeders and scavengers tend to have harder, more protected bodies.

White grubs (a) often occur in soil, decaying organic matter, rotting logs, etc. Wireworms (b) have hard, cylindrical, bodies.
