What are army worms?
Army worms are a type of caterpillar that are known for their destructive feeding habits. They earned their name because they often move in large groups, like a marching army, and can quickly consume entire fields of crops. These pests are not picky eaters and can feed on a wide variety of plants, including corn, cotton, rice, and wheat.
The adult army worm is a dull gray or brown moth that lays its eggs on leaves or stems of plants. Once the eggs hatch, the young caterpillars begin to feed on the plant, growing larger and more destructive as they mature. The life cycle of an army worm typically lasts about a month, during which time they can cause significant damage to crops.
Life cycle of army worms
Armyworms are a type of caterpillar that belong to the order Lepidoptera. They are the larvae of specific moth species, notably the common armyworm moth and the fall armyworm moth. These pests are known for their voracious appetites that can quickly destroy entire fields of crops. Understanding the life cycle of armyworms is essential for effective control and prevention strategies.
- Egg Stage: Adult moths lay their eggs in masses, usually on vegetation, where they will remain for 2-3 weeks before hatching. Each batch can contain up to 500 eggs.
- Larval Stage: Newly hatched armyworms feed voraciously on vegetation, growing quickly and going through several molts as they mature. The larvae stage usually lasts 2-3 weeks.
- Pupation: When the worms reach maturity, they burrow into the soil and molt into pupae. They remain in the pupal stage for 1-2 weeks.
- Adult Stage: After pupation, armyworms emerge as adult moths. The lifespan of the adult moth varies depending on the species but can last anywhere from a few days to a few weeks.
Armyworms thrive in warm and humid weather, with optimal temperatures between 70-80°F. They can complete a full life cycle in as little as 30 days. The most significant damage from armyworm infestations is done during the larval stage, where they can consume entire fields of crops in a matter of days. Early detection and immediate treatment are crucial to prevent significant yield losses.
| Stage | Duration |
|---|---|
| Egg | 2-3 weeks |
| Larvae | 2-3 weeks |
| Pupal | 1-2 weeks |
| Adult | Varies depending on species |
Effective management of armyworm infestations relies on early detection and action. Familiarizing yourself with the life cycle of armyworms can help you identify vulnerable stages and implement appropriate control measures.
Habitat of Army Worms
Army worms are a type of caterpillar that are found in various habitats around the world. They are known to inhabit grasslands, forests, and crop fields. These worms can survive in a wide range of temperatures, from tropical to cold regions. Army worms are known for their ability to thrive in areas where grass is abundant, often resulting in outbreaks of infestations.
- Army worms are commonly found in the southern United States, Mexico, and parts of South America.
- They are also prevalent in Africa and Asia, where they cause significant damage to crops.
- These pests are adaptable and can thrive in different types of ecosystems, from prairies to forests.
Army worms are known to feed on various types of grass, including wheat, corn, sorghum, and rice. They have a preference for young, lush plants and can cause significant damage to crops if not controlled. In addition to their destructive feeding habits, army worms are also known to migrate in large numbers, consuming everything in their path. These migrations can result in severe crop loss and damage to the environment.
| Habitat | Temperature Range | Preferred Food Source |
|---|---|---|
| Grasslands | Temperate to Tropical | Grass species, including wheat and corn |

Natural Enemies of Army Worms
In nature, there is always a balance. As army worms wreak havoc on crops and vegetation, their natural enemies are not far behind. These enemies play a crucial role in controlling the population of army worms and maintaining a healthy ecosystem. Here are some of the natural enemies of army worms:
- Parasitic Wasps – These tiny wasps lay their eggs inside the army worm larvae. The eggs hatch, and the wasp larvae feed on the army worm from inside, eventually killing it.
- Predatory Beetles – There are several species of beetles that eat army worm eggs, larvae, and pupae. These beetles are important natural predators of army worms.
- Birds – Many species of birds feed on army worms and other pests. Birds such as crows, grackles, and starlings have been known to peck at army worm pupae in the soil, reducing their population.
While these natural enemies may not completely eradicate army worms, they can certainly make a dent in their population. Farmers and gardeners can encourage the presence of these natural enemies by planting diverse crops and avoiding the use of harmful pesticides.
It is important to note that these natural enemies are harmless to humans and animals. In fact, they can be incredibly beneficial to our environment. By promoting a healthy ecosystem, we can reduce our reliance on harmful chemicals and pesticides and create a more sustainable future.
Below is a table summarizing some of the natural enemies of army worms:
| Natural Enemy | What They Eat |
|---|---|

Prevention and Control Measures for Army Worms
As an expert blogger, I am here to provide practical prevention and control measures for army worms. It is crucial to take these measures because army worms can cause significant damage to crops and pastures, resulting in considerable economic loss.
- Crop rotation: Crop rotation is an effective way of preventing army worm infestation. It involves planting different crops in a specific order to break the pest’s cycle and interrupt its life cycle. The army worms’ eggs and larvae that remain in the soil cannot reproduce without their preferred crop, thus minimizing future army worm populations.
- Early detection: Early detection of army worm infestations can be achieved through routine monitoring of crops and pastures. Once an infestation is detected, contact a professional pest control service immediately.
- Natural predators: Introducing natural predators such as birds, lizards, and wasps help control army worm populations. Birds such as sparrows and quails feed on the army worms’ larvae and eggs. In contrast, certain wasp species parasitize the army worm eggs, significantly reducing the population. Lizards also feed on army worms.
Integrated Pest Management
Integrated Pest Management (IPM) is an essential prevention and control measure that harmonizes biological, cultural, and chemical pest management practices. This practice focuses on applying pesticides as a last resort and only when absolutely necessary.
IPM incorporates the principles of crop rotation, early detection & monitoring, and biological control. Additionally, farmers and pest control services are equipped with information to monitor the pest’s development to determine the best time to take preventive action.
Chemical Control
Chemical control should be a last resort because it destroys not only army worms but also beneficial organisms and essential soil microorganisms. However, some situations may necessitate its use when the infestation is widespread and threatens livelihoods.
Before using chemical control measures, it’s crucial to identify the army worm species and use the appropriate pesticide. We recommend consulting a professional pest control service for guidance on the most effective and safe pesticides for use.
| Pesticide | Action |
|---|---|
| Chlorpyrifos | It’s a commonly used pesticide for army worm control. It acts on the pest’s nervous system, causing them to die within hours of application. |
| Pyrethroids | Pyrethroids cause paralysis and death in army worms. They are relatively less harmful to non-target organisms than other insecticides. |
| Organophosphates | Organophosphates cause a breakdown in the army worm’s nervous system, leading to paralysis and death. They have long-lasting effectiveness, but are relatively more toxic to non-target organisms than other insecticides. |
Application of chemical control measures should be done by a professional pest control service to avoid misusing chemicals and exacerbating other environmental problems.
In summary, the prevention and control measures for army worms include crop rotation, early detection, biological control, Integrated Pest Management, and Chemical Control. Adopting these measures will help prevent army worm infestation and reduce financial losses. In case of an infestation, contact a professional pest control service for advice and assistance.
