In all three species, their typical caterpillar-shaped larvae should not be confused with the legless leatherjacket which is also a common underground larva. (Credit: C. DiFonzo). The emails began with a message from Oceana County, followed closely by a message from nearby Wexford County (Fig. But by afternoon they shrink in size.” (P. Durst, Oscoda County MSUE, personal communication, November 14, 2007). Without the email outbreak, many facets of the insect outbreak would not have been captured in such detail as it unfolded. The cutworm species normally have two life cycles per year, but in hot summers this may increase to three. 1A). Cook Arthropod Collection records), and moths are now captured regularly around lights between June and October. The damage resembles that caused by slugs. Small grains in defoliated areas were replaced by weeds.

Caterpillars moved en masse from agricultural fields into home lawns (Fig. The first N. pronuba moths found in North America were collected in Nova Scotia in 1979 (Neil 1981). (Credit: J. O'Donnell). Adults are easily recognized by a showy orange hind wing bordered by a black bar (Fig. N. pronuba caterpillars infest a home lawn in October 2007 (A). Neil The term ‘cutworm’ refers to the habit that these worms have of chewing right through the stem of a plant. 1A). 2). In Europe, it is a minor pest of ornamental plantings and gardens (Wright and Neil 1983, Neil and Specht 1987). The farmer said within a day of moving into this field, they reversed course and headed to his white plastic Ag-Bags of stored silage (Fig. Larvae usually fed in the evening.

In Michigan, Michigan State University Diagnostic Services, a laboratory that provides insect identifications for the general public, has received specimens from concerned homeowners every fall since the early 2000s. (Credit: J. Lindquist). Another extension educator in the Upper Peninsula of northern Michigan walked a 1-yr-old seeding and said “The stand doesn't seem so bad. Cutworms are moth larvae that hide under litter or soil during the day, coming out in the dark to feed on plants. Noctua fimbriata is of a similar size to N. pronuba but the black border on the hindwings is very broad (almost one-half width of the wing). While defoliation did not kill alfalfa plants, a short-term reduction in first-cutting yield in 2008 and a long-term negative effect of defoliation and weed competition on stand longevity were suspected, but not confirmed. The adult moth, 2 cm across, with brown fore-wings and yellow or orange hind wings, emerges from the shiny soil-borne chestnut brown pupa from June to July, and lays about 1000 eggs on the stems of a wide variety of weeds. By late October, commercial winter wheat fields, as well as rye and oat cover crops, were completely defoliated in Alpena, Cheboygan, Lake, Mason, Oceana, and Osceola counties (Fig. The authors developed a two-page diagnostic bulletin for N. pronuba, and MSU extension offices provided this handout to veterinarians in northern counties to make them aware of the potential problem. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds … As extension educators made farm visits, they observed that fields with low, wet margins were at greater risk; larvae moved out of these low areas into fields to feed. Map of Michigan showing the locations of Noctua pronuba observations and complaints between fall 2007 and spring 2008. Noctua pronuba, or the Yellow Underwing, is named after the brightly coloured hindwings. Pyrethroids such a permethrin were very effective, although growers also reported using chlorpyrifos and carbaryl. I can say this, Noctua pronuba definitely prefers alfalfa to grass. This observation differed from earlier reports that larvae preferred grasses (Wright 1987). However, not all noctuids are cutworms, and in fact, there are a couple other moth species which have similar behaviors. The initial recommendation, before we fully understood the level of cold tolerance of N. pronuba caterpillars, was to suggest no action on the part of farmers, letting a hard freeze take care of the problem. In alfalfa fields, caterpillars climbed up plants to feed first on leaves, then on small stems, resulting in heavily defoliated crowns (Fig. The outbreak, as well as aspects of N. pronuba biology, is documented in this article using original emails and pictures sent by first responders between fall 2007 and spring 2008.

III, T 32 - Stz. Species, Insect - moth, Terrestrial . The yellow hindwings have a narrow black band without the dark crescent or … This is a rye field adjacent to an alfalfa field (Fig. The caterpillars are named cutworms, because they damage plants by chewing through the stems, cutting them at the base. As stated by Wagner (2005) “if someone brings you a cutworm in the dead of winter—this is it.” In early January 2008, a television news crew from Cadillac, MI, filmed caterpillars crawling on the snow surface when the air temperature was −3°C (26°F). That concern was well-founded. Despite this activity in the fall, N. pronuba is not considered a serious pest in Europe and was not reported to cause economic damage in Canada or the U.S. This is the first confirmation of damage by this cutworm to commercial field crops in North America. N. pronuba caterpillars are usually noticed as they crawl around buildings and on lawns well after other insects have died or overwintered. Thousands of new, high-quality pictures added every day.

In the morning they are as big and fat as a man's little finger. The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. This was the first confirmation, to our knowledge, of damage by N. pronuba to commercial field crops in North America. III, T 9 Culot, Noc. Author: Jan Zima. The larvae are able to crawl from plant to plant, but most spread is by the actively flying adults. As a result of these contacts, there were additional reports of dogs and cats becoming ill after eating caterpillars. Native to western Europe, the insect was first detected in North America during 1979, Therefore, it was not a candidate for a damaging insect outbreak. Crowns survived and fields generally recovered, although slowly. Noctua comes (38-48 mm wingspan) has a large discal spot on each hindwing and lacks the double black spot on each forewing. “I got a rye call this morning as well. This observation matched our assumption that both late and early instars entered the winter, with the last-instars pupating in early spring and the younger (green) larvae continuing to feed on weeds and winter grains into late spring. Noctua pronuba es una mariposa nocturna. Specht Pyrethroids and carbaryl registered for turf were used in November to reduce defoliation of lawns and as barrier treatments around homes. . Noctua pronuba (L.) (Lepidoptera: Noctuidae), the large yellow underwing, is one of the most common Noctuid moths in Europe and the type species for the family Noctuidae. However, extension staff, farmers, and homeowners observed that birds and squirrels feasted on caterpillars in large numbers with no apparent side effects. (Credit: E. Elsner).

Présentation de Noctua pronuba (Hibou (Le)) : noms scientifiques et vernaculaires, statut de protection (listes rouges, réglementations), statut biologique en France Métropolitaine, données historiques et … Adults are strong fliers, thus this non-native species spread rapidly across Canada into neighboring provinces (Morris 1985, 1987), then to the west coast of Canada (Copley and Cannings 2005), and southwest into the United States as far as Texas (Wagner 2005). Because defoliation potentially reduced above-ground biomass protecting alfalfa crowns from winter kill, the recommendation shifted to spraying heavy infestations of caterpillars. Caterpillars are active in the fall, with a portion of the population entering winter as last-instars (pupating in early spring) and the remainder entering as earlier instars (continuing to feed in spring) (Wright 1987). Well, low and behold a very nice ex-pupa … The field was sown last fall and the headed rye was mowed down in August of this year to reseed it.
