“…Egg and larval sampling techniques are rarely used to estimate rootworm populations and to make management decisions in commercial Þeld corn because of the intensive amount of time and labor involved in collecting and processing soil samples (Bergman et al 1981, Ruesink 1986, Tollefson 1990). Adult sampling techniques have been successfully used to estimate corn rootworm population density levels and to develop economic thresholds (Roselle 1977, Stamm et al 1985, Tollefson 1990) for larval or adult control situations. Currently, the visual or whole-plant beetle count sampling method is most commonly used by agriculture professionals to make rootworm management decisions.…”

“…In experiment 1 (1995) and experiment 2 (1996) the maximum larval injury resulted only in feeding scars and minor root pruning on most plants without signiÞcant yield loss. The mean root damage rating across hybrids was 2.9 Ϯ 0.1, which is near the minimum root injury index (2.50 Ð2.75) that has been reported to cause economic yield loss in yellow dent hybrids (e.g., Turpin et al 1972, Stamm et al 1985, Gray and Steffey 1998. In experiment 2 (1995: mean root rating 3.4 Ϯ 0.2) and experiment 1 (1996: mean root rating 3.9 Ϯ 0.1), root injury resulted in the equivalent of one node of roots pruned to near the base of the root on some plants and was associated with a 12.2 and 9.7% yield reduction, respectively, across hybrids.…”

“…A relationship between root injury and yield loss was established by Turpin et al (1972) and has been modiÞed in subsequent studies (Stamm et al 1985, Mayo 1986, Sutter et al 1990, Davis 1994, Gray and Steffey 1998. Root damage scales based on levels of larval injury (i.e., Mayo 1986) at the end of the larval period have been used as economic injury indices.…”

“…management strategies clear. Subsequently, an understanding of the relationship between adult populations in one year and larval damage the following year allowed producers to assign a risk level to larval injury and use responsive, rather then preventative, tactics (Pruess et al, 1974;Stamm et al, 1985). Either crop rotation or application of an insecticide was recommended if adult populations of more than one per plant were detected the previous year.…”

Commercial, genetically-modified (GM) maize was first planted in the United States (USA, 1996) and Canada (1997) but now is grown in 13 countries on a total of over 35 million hectares (>24% of area worldwide). The first GM maize plants produced a Cry protein derived from the soil bacteriumBacillus thuringiensis (Bt), which made them resistant to European corn borer and other lepidopteran maize pests. New GM maize hybrids not only have resistance to lepidopteran pests but some have resistance to coleopteran pests and tolerance to specific herbicides. Growers are attracted to the Btmaize hybrids for their convenience and because of yield protection, reduced need for chemical insecticides, and improved grain quality. Yet, most growers worldwide still rely on traditional integrated pest management (IPM) methods to control maize pests. They must weigh the appeal of buying insect protection "in the bag" against questions regarding economics, environmental safety, and insect resistance management (IRM). Traditional management of maize insects and the opportunities and challenges presented by GM maize are considered as they relate to current and future insect-resistant products. Four countries, two that currently have commercialize Bt maize (USA and Spain) and two that do not (China and Kenya), are highlighted. As with other insect management tactics (e.g., insecticide use or tillage), GM maize should not be considered inherently compatible or incompatible with IPM. Rather, the effect of GM insect-resistance on maize IPM likely depends on how the technology is developed and used.
