What is a cotton worm? What is the most important information about it?
The cotton moth, African cotton leafworm, or Spodoptera littoralis is a moth belonging to the Noctuidae family. The cotton leafworm belongs to the order Lepidoptera. Its body length ranges from 14 to 18 mm, and its wings range from 27 to 38 mm.
Symptoms of infection:
Based on the information I mentioned about the cotton leafworm, several symptoms that indicate worm infection can be identified, which are as follows:
- Plant leaves are colored yellow or brown.
- Holes and damage spots in the leaves as a result of caterpillars feeding on them.
- Leaves fall in large quantities.
- Stunting and damage of flowers and fruits due to infection by caterpillars.
- Dark spots appear on plant leaves.
- Deformation of leaves and fruits.
- Slow growth and weakness of plants.
- An increase in the number of larvae on infected plants.
- Fruits open before ripening as a result of holes caused by larvae.
- Accumulation of larval remains and feces on plant leaves.
These symptoms indicate the presence of a cotton leafworm infestation and require taking measures to combat it and protect crops
Cotton leafworm food
The cotton leafworm is a leaf-eating insect that feeds on a variety of plants, including cotton plants, tomatoes, corn, and other vegetables. They feed on plant leaves and cause serious damage by eating the leaves and green parts of the plant.
The life cycle of the cotton worm
Based on the information you have provided; you can be reminded of the steps of the cotton leafworm life cycle as follows:
- The fertilized female lays eggs: The female lays eggs on leaves or plants.
- Egg hatching: Egg hatching occurs within two to three days in the summer and can take up to 10-20 days in the winter.
- Larval metamorphosis: The larvae transform from the egg into a small worm called a larva.
- Moults: The larva undergoes six larval stages or molts until it turns into a pupa.
- Pruning: The pupa pupates inside the soil.
- Formation of a butterfly: The pupa goes on to transform into a complete butterfly or insect, and begins a new life cycle.
These are the steps in the life cycle of the cotton leafworm, which includes several stages from laying eggs until the formation of a new moth.
Cotton leaf worm shape
- It is a dwarf insect with a dark gray or light brown color, and is characterized by a body covered with soft bristles.
- On the front wing there are longitudinal and transverse oblique lines colored pale yellow. The male’s color is generally lighter than the female’s.
- The cotton leafworm has a small, pointed head, six legs, and three pairs of legs located in the thorax. Visible traces of patterns may appear on the body.
- The cottontail can have light blue spots near the outer edge of the front wing and other similar, smaller spots near the base of the same wing.
- The female’s antennae rings are longer than the male’s and are less hairy.
- The female is larger than the male.
What are the ways to eliminate cotton leafworm?
There are several methods that can be used to effectively combat cotton leafworm, including:
- Use of insecticides: Approved insecticides can be used to combat cotton leafworm. You must follow the correct instructions for use and follow the recommended doses.
- Integrated agriculture: Integrated agriculture is considered one of the environmental and effective ways to combat insect pests, including the cotton leafworm. This approach includes the use of innovative techniques such as cultivation of resistant varieties and cultivation of pest-provoking plants.
- Biological control: Biological agents such as parasites and natural enemies can be used to control cotton leafworm naturally without chemical intervention.
- Preventive measures: Preventive measures can be followed, such as cleaning fields regularly and getting rid of infected plants immediately to prevent the spread of pests.
- Control of the planting environment: The planting environment can be improved by better promoting ventilation, humidity and nutrition to increase the vigor of cotton plants against cotton leafworm attacks.
Remember that it is important to consult agricultural experts before taking any control action to ensure that appropriate and safe methods are used.
The most important materials used in combating cotton worms are
- Emamectin benzoate (Proclem).
- Methomyl 90% (Lanet).
- Lambdasalihythrin (Lampada 5%).
- Chloropyrifos 48% (Bestban).
