Bacillus thuringiensis kurstaki (Btk)

Bacillus thuringiensis kurstaki (Btk) is a strain of Bt specifically used for controlling caterpillars in agricultural and garden settings. This strain produces crystal proteins (Cry proteins) that are toxic to caterpillars. When ingested by caterpillars, these proteins paralyze the insect’s digestive system, causing them to stop feeding and eventually die from starvation.

Target Pests:

    Caterpillars of moths and butterflies, such as:

  • Cabbage loopers
  • Gypsy moth larvae
  • Tomato hornworms
  • European corn borers
  • Diamondback moths

How Btk Works:

  • Ingestion: Caterpillars consume Btk spores that are naturally found on plant surfaces. These spores can be ingested when caterpillars feed on plants.
  • Activation: Once the Btk spores enter the caterpillar’s alkaline gut, they undergo a transformation. Btk spores release Cry proteins, which are toxic proteins produced by the bacterium.
  • Toxin Binding: The Cry proteins bind specifically to receptors present on the gut cell membranes of the caterpillar. This binding process leads to the formation of pores or channels in the cell membranes.
  • Gut Paralysis: The formation of these pores disrupts the integrity of the caterpillar’s gut cells. As a result, the gut cells start to lyse or break down. This leads to paralysis of the digestive system, as the gut is no longer able to function properly.
  • Death: Due to the paralysis of the digestive system, the caterpillar’s ability to feed is severely compromised. Within hours of ingesting Btk and experiencing gut paralysis, the caterpillar stops feeding. This ultimately leads to starvation. In addition, the breakdown of gut cells can also release bacterial toxins into the caterpillar’s body, causing septicemia. The combination of starvation and septicemia generally leads to the death of caterpillars within a few days.

Advantages of BTK:

  1. Targeted Action:BTK specifically targets caterpillar pests. It is highly selective in its toxicity towards insects in the order Lepidoptera, including caterpillars, while posing little to no harm to beneficial insects, pollinators, mammals, birds, or aquatic life. This specificity allows for targeted pest control while minimizing adverse effects on non-target organisms.
  2. Environmental Safety: BTK has a long history of safe use in pest management. It is considered safe for humans, as well as mammals, birds, and aquatic life. It quickly breaks down in the environment and does not persist, reducing the risk of accumulation or long-term ecological impact.
  3. Resistance Management: BTK is an effective tool for managing and preventing resistance in pest populations. By integrating Btk with other pest control measures, such as crop rotation, cultural practices, and the use of different insecticides with distinct modes of action, the development of resistance can be slowed or prevented. This is crucial for maintaining the long-term efficacy of pest control strategies.

Application Guidelines for BTK:

  1. Application:Spray thoroughly, ensuring all plant surfaces are covered.
  2. Timing:Apply when larvae are less than 5 mm long or when eggs begin to hatch. Btk is most effective on young larvae.
  3. Temperature Considerations: Apply in the late afternoon in hot climates to maximize effectiveness during cooler hours.
  4. Water pH: Do not mix Btk concentrate with alkaline water (pH 8 or higher). Acidify water by adding white vinegar if necessary.

Recommended crops for BTK:

  1. Vegetables, fruits, ornamentals, and field crops.

    Recommended application :

  1. Foliar sprays, pre-planting applications to seed, post-pruning treatments, incorporation in the soil during seeding or transplant, watering by irrigation, or applied as a root drench or dip.
