Armyworm characteristics

The fall armyworm moth has dark gray, mottled forewings with light and dark splotches, and a noticeable white spot near the extreme end of each. Newly hatched larvae are green in color and move in a looping motion. Fall armyworm larvae are smooth-skinned and vary in color from light tan or green to nearly black True Armyworm (Pseudaletia unipuncta Haworth) Insect Fact Sheet integrated pest management Description Life Cycle Injury University of Illinois Armyworm larvae M. Mo nt go m e r y, U I E x te n s i o n Native to North America, the true armyworm can be found east of the Rocky Mountains, reaching northward into southern Canada The armyworm is a moderately sized moth with a wingspan of approximately 1½ inches. On specimens in good shape, the forewing is tan to reddish-brown with a small white mark in the center. The species name unipuncta is based on this single white point

The adult beet armyworm, Spodoptera exigua, is a grayish brown moth with a pale circular spot near the middle of the forewing. The wingspan is an inch or slightly more. The hind wings are whitish with dark edges. First and second stage caterpillars are pale green with dark heads The fall armyworm is a strong flier, and disperses long distances annually during the summer months. It is recorded from virtually all states east of the Rocky Mountains; however, as a regular and serious pest, its range tends to be mostly the southeastern states Key Characteristics of Fall Armyworm Brown/gray larva with distinct tubercles along body Three thin white stripes down the back and a distinct white inverted Y on head Young larvae may be difficult to distinguish from corn earworm (CEW The Fall Armyworm, its caterpillar, is a notorious pest. It eats a variety of grasses and crop plants, which means it ruins turf and food production. Peanut, rice, soybean, sugarcane, alfalfa, cotton, and corn are some of the victims of the Fall Armyworm's feasting Fall armyworm is a multicolored, striped caterpillar. They often have a prominent, light-colored inverted Y on a dark-colored head, but the head of this species is often lighter in color when it occurs on soybean, in pastures, or on weedy grasses. Armyworms may feed on leaves, stems, and pods

The term armyworm can refer to several species, often describing the large-scale invasive behavior of the species' larval stage. It is regarded as a pest and can damage and destroy a wide variety of crops, which causes large economic damage The map below showcases (in blue) the states and territories of North America where the Fall Armyworm Moth may be found (but is not limited to). This sort of data can be useful in seeing concentrations of a particular species over the continent as well as revealing possible migratory patterns over a species' given lifespan

On site identification as fall armyworm was based on morphological characteristics and, in the case of adults, attraction to a pheromone blend designed for fall armyworm. Genetic characterization of the COI barcode region (COIA, Fig 2) identified one specimen as Mythimna (Leucania) loreyi (Duponchel), which was not further characterized Therefore, a genome-wide analysis of the genetic characteristics of invasive fall armyworm is becoming imperative. Although several versions of the fall armyworm genome have now been published (Gouin et al., 2017; Kakumani, Malhotra, Mukherjee, & Bhatnagar,. The armyworm, Pseudaletia unipuncta, and fall armyworm, Spodoptera frugiperda, are generally considered minor pests, but they have the potential for explosive outbreaks in turfgrass. Descriptions and Life Histories. Armyworms are 1 1/2 to 2 inches long at maturity and vary in color from gray to yellowish green tinged with pink. They have a. One of the characteristics that make this species so successful is how fast it fly, being able to fly over 100 kilometers a night with the right wind ( Parker, 2019).

The fall armyworm, Spodoptera frugiperda (J. E. Smith 1797) (Lepidoptera: Noctuidae), is the most important corn pest in South America. Larvae feed mostly on leaves, but also ears when population densities are high. This pest has been historically controlled with insecticide applications, but many cases of resistance have limited their efficacy dues, and was named armyworm cecropin-1 (AC-1). The amino acid sequence of AC-1 was highly similar to cecropins from other insects (Fig. 2).
