Chlorethoxyfos (O,O-diethyl-O-(1,2,2,2-tetrachloroethyl)phosphorothioate) is an organophosphate acetylcholinesterase inhibitor used as an insecticide. It is registered for the control of corn rootworms, wireworms, cutworms, seed corn maggot, white grubs and symphylans on corn. The insecticide is sold under the trade name Fortress by E.I. du ...
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.
59122 is an insect resistant maize expressing the Cry34Ab1 and Cry35Ab1 proteins for corn rootworm insect pest protection and the PAT protein for glufosinate ammonium tolerance as a breeding tool or weed control option.
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.
It includes two subspecies, Diabrotica virgifera virgifera (the western corn rootworm) and Diabrotica virgifera zeae (the Mexican corn rootworm). [2]
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]

During 2009 and 2010, some Iowa fields showed severe injury to corn producing Bt toxin Cry3Bb1 by western corn rootworm. During 2011, mCry3A corn also displayed insect damage, including cross-resistance between these toxins. Resistance persisted and spread in Iowa. Bt corn that targets western corn rootworm does not produce a high dose of Bt ...
