LARVORID

  • an effective Biological larvicide based on Bacillus thuringiensis – Kurstakii.
  • extensively used to control moth and butterfly (Lepidoptera) pests.
  • widely used to control moth and butterfly (Lepidoptera) pests as it specifically affects the larvae (caterpillars) of many of these species.
  • especially to control gypsy moth populations.
Mode of Action:
  • The protein crystal produced by LARVORID includes a substance known as a delta-endotoxin which is toxic to members of the Order Lepidoptera (moths and butterflies).
  • Endospores of LARVORID are also toxic to the caterpillars.
  • The spores and endotoxins in the protein crystal are known as the "active ingredients" in LARVORID formulations, because it is these ingredients which kill the insects.
  • However, the protein crystal is not toxic until it is swallowed by a caterpillar - it must be present on a leaf and eaten by a caterpillar before it takes effect.
  • Once the crystal is eaten by the caterpillar it is activated by the specific conditions found in the caterpillar gut (namely, alkaline conditions and the presence of certain digestive enzymes).
  • The toxin works by attacking the gut lining. 
  • This causes paralysis of the gut and the caterpillar stops feeding as little as two minutes after eating the LARVORID.
  • The caterpillar will die because of starvation in two to five days later, depending on environmental conditions.
  • Vegetative growth of LARVORID within the caterpillar and septicaemia caused by LARVORID may also help to kill the caterpillar.
