Diabrotica undecimpunctata, the spotted cucumber beetle or southern corn rootworm, is a species of cucumber beetle that is native to North America. The species can be a major agricultural pest insect in North America. Spotted cucumber beetles cause damage to crops in the larval and adult stages of their life cycle.
In the US, it is the most commonly used organophosphate insecticide. [6] A malathion mixture with corn syrup was used in the 1980s in Australia and California to combat the Mediterranean fruit fly. [7] In Canada and the US starting in the early 2000s, malathion was sprayed in many cities to combat west Nile virus. [8]
Specific delta-endotoxins that have been inserted with genetic engineering include Cry3Bb1 found in MON 863 and Cry1Ab found in MON 810, both of which are maize/corn cultivars. Cry3Bb1 is particularly useful because it kills Coleopteran insects such as the corn rootworm, an activity not seen in other Cry proteins. [1]
As a way to reduce rootworm densities, it is more effective than insecticides. [2] Corn rootworm larvae must feed on corn roots to develop and mature properly. If they hatch in a field without corn, they starve because they cannot move more than 10 to 20 inches (510 mm) in search of food. [9] However, two rootworm biotypes survive rotation.
Carbofuran is a carbamate insecticide, banned in the US, the EU and Canada but still widely used in South America, Australia and Asia. [6] It is a systemic insecticide, which means that the plant absorbs it through the roots, and from there the plant distributes it throughout its organs where insecticidal concentrations are attained.
