Carpocasae nematode treatment to control Colorado potato beetle larvae

Colorado potato beetles (Leptinotarsa decemlineata) are insect pests that pose a threat to potato crops worldwide.
Colorado potato beetles are recognizable by their orange bodies and distinctive black stripes.

Steinernema Carpocapsae (SC) nematodes are microscopic worms that are used as a biocontrol treatment against Colorado potato beetles.

When applied to the soil or to potato leaves infested with Colorado potato beetle larvae, the nematodes actively search for their prey. Once in contact with a Colorado potato beetle larva, the nematodes penetrate through the natural orifices of the insect. Once inside, the nematodes release specific symbiotic bacteria which multiply rapidly and cause the death of the larva.

The bacteria released by the nematodes produce toxins and enzymes that degrade the tissues of the Colorado potato beetle larva, leading to its death. The nematodes then feed on the bacteria and decaying tissue, reproduce and seek out new prey.
The action of nematodes against Colorado potato beetle larvae is considered an effective and environmentally friendly method of biological control, as it specifically targets the pest without harming other beneficial organisms or humans.

How to use nematodes to control Colorado potato beetles

1. Identify the problem
Damaged leaves: Colorado potato beetles are best known for their voracious appetite for potato leaves. Both adults and larvae chew the leaves, creating holes and scars. They can devour leaves completely, leaving only the veins, in a behavior known as "skeletonization".
Yield reduction: Leaf damage by Colorado potato beetles can cause a significant reduction in crop yield. Potato plants need their leaves for photosynthesis, which fuels the growth of tubers (potatoes). If a large number of leaves are destroyed, the growth of the plant is hampered, which leads to a decrease in the size and number of tubers produced.
It is possible to act on the larvae by applying the nematodes to the foliage.
It is also recommended to treat the soil after harvesting potatoes. The Colorado potato beetle larvae fall off the leaves and move through the soil at this time. This is the perfect time to fight them with nematodes. This helps prevent a new infestation of beetles the following season.

2. Preparation of nematode solution
Bring nematodes to room temperature 30 minutes before use. To mix the nematodes well, it is recommended to dilute the entire sachet in a small container of clean water at room temperature by pre-diluting the nematodes before mixing them. Stir this mixture well and allow the contents to dilute for 5 minutes. If there are any lumps left, that's okay, but it could clog the nozzles. Then, pour this preparation into your watering can or sprayer and add the rest of the water (between 15°C and 25°C). Mix again.

3. Application by spraying or watering the nematodes on the palm
Before applying the nematode solution to the plants, moisten the plants and the soil. This will allow the nematodes to move more easily to their prey. Since nematodes do not have legs, they use moisture in combination with foliage particles to move around. Spray while continuing to agitate the mixture to prevent the nematodes from ending up all at the bottom of the sprayer or watering can.

4. Continue humidification
Nematodes need a moist environment to move to their prey. To maintain their effectiveness, continue to water your crop regularly.

5. Monitor results
Steinernema Carpocapsae nematodes are fast enough to control Colorado potato beetles. You should notice a decrease in the larval population after a few days. However, be careful, as the nematodes process the larvae, so you might still see adults. If the larvae persist, it is necessary to repeat the treatment.
It is important to follow application instructions for best results when treating Colorado potato beetles with Steinernema Carpocapsae nematodes.
