Techniques

Types of Treatment: Biological

The greatest success in biological control has undoubtedly been the use of bacterial larvicides. Two of these products are routinely used at the MCS:

Bacillus thuringiensis var. israelensis
applied against larvae from the genus Ochlerotatus .

Bacillus sphaericus
used to control Culex pipiens.

The toxicity of these insecticides is governed by the proteins accumulated by the bacteria. This makes them highly target-specific and means that their toxic effects on other organisms are very low. More than 95% of MCS treatments are performed using these two products.
