“…These markers are appropriate for incorporation into linkage mapping studies. Laboratory colonies of O. nubilalis that exhibit moderate resistance to Cry1Ab toxin in artificial diet (Bolin et al, 1999;Huang et al, 1999;Chaufaux et al, 2001), and diagnostic bioassays can discriminate phenotypes (Marcon et al, 2000). OnTBR1 and OnTBR2 PCR-RFLP markers show Mendelian inheritance (Table 1), which is required for genetic mapping procedures (Pemberton et al, 1995).…”

“…High selection pressure and adaptation to transgenic toxins by O. nubilalis larvae raises concerns regarding sustainability of Bt technology. Commercial hybrid maize expressing Cry1Ab toxins were grown on 29% of 2003 United States corn acres (22.9 million acres; USDA-NASS, 2003 (Bolin et al, 1999;Huang et al, 1999;Chaufaux et al, 2001).…”

“…Resistant strains have been selected from populations collected in Iowa, Kansas, (Huang et al 1997(Huang et al , 1999a, and southeastern Minnesota (Bolin et al 1999). The high-dose refuge strategy currently recommended for U.S. corn production (Ostlie et al 1997, International Life Sciences Institute 1998 requires that the increased Þtness conferred by Bt resistance alleles is recessive, i.e., heterozygous individuals either do not survive at doses of toxin produced by Bt corn or survive but with a Þtness close to zero (Bourguet et al 2000).…”

“…Survival and Þtness of heterozygotes depends not only on the dominance of B. thuringiensis resistance but also on the resistance level conferred by resistance alleles (Bourguet et al 2000). Therefore, it is important to determine whether the relatively low resistance ratio reported by Huang et al (1997Huang et al ( , 1999a and Bolin et al (1999) is a general feature in O. nubilalis populations or whether higher B. thuringiensis resistance can be obtained in laboratory-selected populations.…”

“…Extensive planting of Bt crops and season-long exposure to toxins has caused concern that Bt resistance may develop in target pests (Tabashnik et al 2008). This concern is supported by the development of Bt-resistant strains in laboratory settings (Tabashnik et al 1990, Bolin et al 1999, Huang et al 1999, Pereira et al 2008, Tabashnik et al 2008, Gassmann et al 2009, Crespo et al 2009, and the discovery of Bt-resistant populations surviving in the Þeld (van Rensburg 2007, Tabashnik et al 2008, Storer et al 2010, Dhurua and Gujar 2011, Gassmann et al 2011, Zhang et al 2011. Many insect resistance management (IRM) strategies have been considered, but the high-dose refuge (HDR) strategy has been adopted by regulatory, academic, and industry scientists as the standard for IRM (Gould 1998, Tabashnik et al 2004.…”

On-Plant Selection and Genetic Analysis of European Corn Borer (Lepidoptera: Crambidae) Behavioral Traits: Plant Abandonment Versus Plant Establishment

Although some studies have investigated how insect behavior could influence resistance evolution to transgenic plants, none have determined if behavioral traits respond to selection pressure and how they may be inherited. We investigated plant establishment and abandonment traits for the European corn borer, Ostrinia nubilalisi (Hübner) (Lepidoptera: Crambidae), by conducting a laboratory selection experiment and quantifying patterns of gene expression. Egg masses with emerging larvae were placed on maize plants and silking individuals were collected every 15 min during a 4-h period to generate a plant abandonment (PA) colony. Plants were dissected 24-72 h later, and larvae were collected for a plant establishment colony. Selection of the PA colony showed an increased propensity to abandon the host plant by the third generation. The propensity for larvae to establish on the plants, however, did not show a significant response until the sixth generation. Quantitative real-time-polymerase chain reaction (qRT-PCR) was used to determine expression profiles for behavior associated genes (foraging and Onslmo). Egg samples from the two selected colonies and nonselected laboratory colony were collected at 0, 24, 48, 72, and 96 h after egg deposition, and first instars were sampled after exposure to maize tissue. Compared with the plant establishment and nonselected laboratory colonies at the 0-h time period, foraging and Onslmoshowed higher expression in the PA colony. This is the first study that has specifically selected for these traits over several generations and analyzed behavior-associated genes to elucidate genetic changes.

ABSTRACT Although some studies have investigated how insect behavior could inßuence resistance evolution to transgenic plants, none have determined if behavioral traits respond to selection pressure and how they may be inherited. We investigated plant establishment and abandonment traits for the European corn borer, Ostrinia nubilalisi (Hü bner) (Lepidoptera: Crambidae), by conducting a laboratory selection experiment and quantifying patterns of gene expression. Egg masses with emerging larvae were placed on maize plants and silking individuals were collected every 15 min during a 4-h period to generate a plant abandonment (PA) colony. Plants were dissected 24 Ð72 h later, and larvae were collected for a plant establishment colony.
