ReayJones, Extension Entomologist Grain yield reductions and losses in grain quality due to insect pests are a constant problem in the Southeast. Control options include cultural practices to prevent or avoid injury, transgenic Bt corn, at‐planting insecticides (including seed treatments), and foliar insecticides. Insect pressure varies greatly from field to field. Decisions concerning pest management options should therefore be made in careful consideration of the history of insect problems in each field where corn is to be planted. Major insect pests of corn in South Carolina. Insect Description of feeding habit Methods of control Wireworms Feed on planted kernels resulting in poor germination and stunted seedlings Insecticide, tillage, control of winter weeds Cutworms Girdling of stalk at soil surface Avoid planting corn on sod or weedy land, selected Bt hybrids, insecticides Sugarcane beetles Burrow into stalk above base of roots Plant early and do not plant corn after sod Billbugs Chew into stalk and cause bud leaves to wilt and die Crop rotation, weed removal in and around corn field, insecticides Corn earworms Feed on leaves in whorl and on ear tissue near ear tip Insecticides, selected Bt hybrids, plant early Fall armyworms May feed on all above ground parts of corn plant Bt hybrid, insecticides, plant and harvest early, control grassy weeds Lesser cornstalk borers Tunnel into corn seedling Crop rotation and early planting, selected Bt hybrids, insecticides Several types of Bt corn are available, each characterized by an ‘event’ (i.e. a successful insertion of the genetic package into a plant) and cry proteins. In a nutshell, there are Bt traits for above‐ground pests and Bt traits for rootworms. Please refer to table below for efficacy of available products. Bt traits for aboveground pests. - Herculex I (event TC1507, protein Cry1F). - Optimum Intrasect (events TC1507 and MON810, proteins Cry1F and Cry1Ab). - Optimum Leptra (events TC1507, MON810, and MIR162, proteins Cry1F, Cry1Ab and Vip3Aa20). - YieldGard CB (event MON810, protein Cry1Ab). - Genuity VT Double Pro (event MON89034, proteins Cry1A.105 and Cry2Ab2). - Agrisure Artesian 3010A (event Bt11, protein Cry1Ab). - Agrisure GT/CB/LL (event Bt11, protein Cry1Ab). - Agrisure Viptera 3110 (events MIR162 and Bt11, proteins Vip3Aa20 and Cry1Ab). - Agrisure Viptera 3220 (events MIR162, TC1507, proteins Vip3Aa20, Cry1Ab and Cry1F) - PowerCore (events MON89034 and TC1507, proteins Cry1A.105, Cry2Ab2, and Cry1F) - All products provide excellent control of stalk borers (European corn borer, southern cornstalk borer). The activity in seedling and whorl stage is greater in Herculex I, which provides good early season control of cutworms, lesser corn stalk borer, and fall armyworm. YieldGard CB and Agrisure CB/LL have fair activity for corn earworm infestations in corn ears, whereas control with Herculex I is poor. The more recent Genuity VT Double Pro is the first Bt corn to have
