RAPAX®

 
Insecticides based on Bacillus thuringiensis kurstaki
(Strain EG 2348; a.i. coc. 7.5%) - Suspension concentrate.
 
   

RAPAX

RAPAX® is one of the first biological insecticides based on a Bt serovar kurstaki strain that has been created through transconjugation.
The Bt strain EG 2348 contains several genes producing insecticidal Cry toxins, which are effective against loopers resistant to chemical insecticides. RAPAX® thus provides more efficient control than many conventional chemical treatments and other Bts. In Europe, its major targets are: European Grape Berry Moth (Lobesia botrana), Grape Berry Moth (Eupocilia ambiguella), Orchard Leafrollers (Argyrotaenia pulchellana, Archips spp., Pandemis spp.), Olive Moth (Prays oleae), CitrusMoth (Prays citri), European Corn Borer (Ostrinia nubilalis).

Bt products

Bacillus thuringiensis (Bt) is a naturally occurring, soil-dwelling, Gram-positive bacterium. During sporulation it produces a translucent crystal protein, the active ingredient of the formulated products.The crystal protein is a protoxin with insecticidal activity, which is activated in the alkaline midgut of certain insects.
Bt thus acts as a gut poison. Once the target pest has ingested the crystal protein, it stops feeding immediately, and dies within two days.

History

The ability of Bt to control pest insect larvae was discovered more than 90 years ago. However, it was first commercially used only in the 1940's. Bacillus thuringiensis serovar kurstaki (HD-1) was discovered in the late 1960's. This serovar is considerably more effective against caterpillars and easier to produce than the early Bts, and therefore most marketed Bt-products contain HD-1.

The novel Bt strain EG 2348, the active ingredient of Biogard's Btformulations, was created using advanced techniques of molecular biology through a process called transconjugation.

These Bt strain produces different Cry toxins (Cry 1Aa, 1Ac, and 2A toxin), which are responsible of the insecticidal activity and the enhanced efficacy against specific target insects of the Bt strain.
