Abstract:
Stalk rots, caused by a complex of fungal species, are among the most widespread and destructive diseases of maize. Larvae of the European corn borer (ECB) (Ostrinia nubilalis) promote stalk rot development by creating entry points for fungi, serving as vectors of pathogens, and causing physiological stress that may predispose plants to stalk decay. Field experiments were conducted in 1998, 1999, and 2000 to determine whether the use of transgenic Bt hybrids expressing insecticidal proteins would influence stalk rot symptoms (pith disintegration, pith discoloration, and lodging). Five hybrids representing different Bt types (or “Bt events”) (176, BT11, MON810, DBT418, and CBH351) were paired with their near-isogenic, non-Bt counterparts and subjected to treatments of manual and natural infestation with ECB larvae. Manual infestation resulted in significantly more ECB tunneling than natural infestation in 1998 and 1999 and significantly more lodging in 1998. There were significant linear correlations between ECB injury and stalk rot symptoms in non-Bt hybrids in 1998 and 1999, but not in 2000. A standard foliar insecticide treatment for ECB did not significantly affect stalk rot symptoms. In 1998, Bt hybrids had significantly less ECB tunneling, stalk discoloration, pith disintegration, and lodging compared with non-Bt hybrids, but these effects depended upon the Bt event and the infestation treatment. Similar but less pronounced effects of Bt events were observed in 1999. The 2000 results were more variable; the amount of pith disintegration was significantly lower but discoloration was significantly higher in the BT11 hybrid compared with its non-Bt counterpart, and the amount of lodging was significantly higher in the event 176 hybrid compared with its non-Bt counterpart. The ratio of stalk strength to grain weight did not consistently differ between Bt and non-Bt hybrids. These results indicate that, although specific Bt events in some years may cause reductions in stalk rot, the overall effect of Bt transformation on stalk rot occurrence is highly variable.

Abstract:
AbstractA simulation model was developed to predict the timing of European corn borer, Ostrinia nubilalis (Hbn.), larval mortality following exposure to Beauveria bassiana (Bals.) Vuillemin conidia. Model response was compared with laboratory and field data collected specifically for model validation. In laboratory validation experiments, four conidial doses of a B. bassiana isolate collected from the People’s Republic of China were applied to European corn borer larvae which were then incubated at fluctuating temperatures. Simulation results compared favorably with fungal development and mycosis under laboratory conditions. Field validation experiments showed that applications of B. bassiana to European corn borer neonates in whorl-stage corn resulted in mortality levels over 60% when conidia and European corn borers were placed on the plants on the same day. When B. bassiana conidia were placed on plants prior to European corn borers, mortality decreased linearly with time. Model predictions of the timing of European corn borer mortality were found to be accurate when B. bassiana conidia were placed on corn plants at the same time or prior to European corn borers. When European corn borers were placed on plants prior to conidia, the model underestimated the time to European corn borer death. Lack of model fit in this situation is thought to be due to delayed host and pathogen interactions on the corn plant rather than poor prediction of the physiological development of the disease.

Abstract:
The impact of European corn borer (Ostrinia nubilalis) [Lepidoptera: Pyralidae] infestation and stalk rot infection caused by Gibberella zeae on yield of eight grain maize (Zea mays) inbreds, two commercial and six experimental hybrids was evaluated from 1975 to 1980. Three criteria were used: leaf feeding, total plant damage at harvest and tunnel length/plant height ratio. For most criteria, the cultivars were significantly different and the artificial European corn borer infestation had an effect almost every year. Although G. zeae can have a signifiant effect on plant damage at harvest and yield of grain maize, no consistent link was found between stalk rot and European corn borer.

Abstract:
Two types of pregelatinized corn flour were used to produce granules containing Bacillus thuringiensis Berliner subsp. kurstaki and various additives for control of the European corn borer, Ostrinia nubilalis (Hübner), in the whorl of corn plants. Laboratory-reared larvae were applied to corn whorls in the greenhouse and field, and a high natural infestation occurred at one field site (Champaign). In the greenhouse and at all three field sites, five of these formulations were just as effective as Dipel 10G, a commercially available B. thuringiensis product, for control of European corn borer larvae. In all greenhouse studies and at one of the three field sites (Champaign), the dose of B. thuringiensis could be reduced by as much as 75% when a phagostimulant was added to flour granules without significant loss of corn borer control. The phagostimulant dose response was not observed at the other two field sites in which larval infestations were relatively low. Flour type had no significant effect on European corn borer control under greenhouse and field conditions. Greenhouse evaluations provided results significantly similar to results from two of the field sites indicating the usefulness of the technique. The data presented highlight the versatility and potential for using novel formulation techniques for enhancing the efficacy of B. thuringiensis.

Abstract:
Ground-applied treatments of two commercial Bacillus thuringiensis subsp. kurstaki formulations (MVP and Dipel ES) and tank-mixes with a pyrethroid (Ambush 2E) were evaluated for control of European corn borer, Ostrinia nubilalis (Hübner), larvae in sweet corn. Treatments were applied at average intervals of 3.4, 5, 7, and 10 days to determine field persistence. Manual infestations of first-instar O. nubilalis were used to augment natural populations. During both years, there were no significant interactions between application interval and treatment for all dependent variables tested, including late instars per ear, percent marketability, yield, and predator density. Regardless of application interval, MVP provided greater larval control than Dipel ES. However, the decline in efficacy of the encapsulated MVP formulation occurred at the same rate as that of the non-encapsulated Dipel ES formulation over the 3.4 to 10-d intervals. Tank-mixes of B. thuringiensis + low-rate permethrin provided no additional control compared with low-rate permethrin alone. Given the infestation levels present in this test, neither B. thuringiensis formulation provided control sufficient to maintain current processor standards of 5–10% infested ears at harvest.

Abstract:
Experiments were conducted using tritiated European corn borer, Ostrinia nubilalis (Hübner), pheromone, (Z)-[11,12-3H2]-11-tetradecen-1-ol acetate, a tritiated fluorinated analog of the European corn borer pheromone, 2-fluoro-(Z)-[11,12-3H2]-11-tetradecen-1-ol acetate, and methyl-4-bromocrotonate (MBC) to determine if pheromone catabolism proceeds on the moth's antennae via the β-oxidation pathway of fatty acid degradation. When antennae were treated with tritiated natural pheromone plus MBC (a precursor of the known β-oxidation inhibitor, 4-bromocrotonic acid), catabolism of the pheromone was significantly inhibited. When the 2-fluoro pheromone analog was applied alone to antennae, it was hydrolyzed to the corresponding alcohol but was not degraded. MBC had no effect on catabolism of the 2-fluoro analog, and 2-fluoro substitution inhibited entrance of the compound into β-oxidation. These results demonstrate that β-oxidation is the primary oxidative pathway by which pheromone is degraded on the antennae of European corn borer moths.

Abstract:
The effect of European corn borer, Ostrinia nubilalis (Hübner), injury during the spring on yield and yield components of winter wheat, Triticum aestivum L. em Thell, was studied. Spike and grain characteristics of infested and uninfested culms were compared in three fields of ‘Florida 302’ winter wheat in eastern Georgia. Feeding on inner stem tissue by larvae killed the grain spike producing a “white head” symptom in wheat. Most larvae (95.2%) tunnelled in the peduncle which caused an average of 3.4% of spikes to be barren. Larval injury did not reduce spike length but did reduce grain weight per spike by 44.6% and grain weight per kernel by 41.9%. Kernel number per spike was reduced by 11.7% mostly because of a 9.9% reduction in kernel number per spikelet. Spikelet number per spike was reduced by 1.8%. Tunnelling by O. nubilalis larvae also reduced grain test weight and quality. These results indicated that a culm infestation of 10% or more would be necessary before control measures would be justified in winter wheat.

Abstract:
Males and females of Ostrinia nubilalis (Hübner) from Alberta were held at constant and variable temperatures within a 17–32 °C range to determine the effect of temperature on longevity, daily oviposition, egg viability, total fecundity, reproductive period, and oviposition rate. The lower developmental thresholds and thermal summations for each stage were calculated from linear regressions. Moths from the South Saskatchewan River valley laid significantly more eggs over a longer period than those from the surrounding plains. The upper threshold for oviposition was higher (27 °C) for valley than for plains borers (25 °C). Optimum temperatures for egg viability were also higher for valley (25–27 °C) than for plains borers (22 °C). Fluctuating temperatures increased survival of both sexes compared with equivalent constant temperatures. Differences in male and female longevity likely arose in response to selection for different reproductive strategies in each sex. Long-lived individuals achieved high fecundity by reproducing at a low rate over many age-classes, while short-lived individuals reproduced at a high rate over few age-classes, with less total fecundity. Fecundity and reproductive period in the corn borer are plastic phenotypes that can change rapidly under differing environments.

Abstract:
We examined the effect of varying thresholds for treatment of first generation European corn borer, Ostrinia nubilalis (Hübner), infestations in early-season fresh market sweet corn in eastern New York over a 3-year period. Seven treatment thresholds were compared: (1) 15% infested plants at whorl stage, 5% infested plants at tassel and silk stage, (2) 15% at whorl stage, 15% at tassel and silk stage, (3) 30% at whorl stage, 5% at tassel and silk stage, (4) 30% at whorl stage, 15% at tassel and silk, (5) 5% at tassel and silk stage, (6) 15% at tassel and silk stage, and (7) control (untreated). When thresholds were reached, permethrin was applied using an air-blast sprayer. Results indicated little difference in percentage marketable ears whether plants were treated or not at whorl stage, and the tassel stage threshold could be raised to 15% infested plants with no significant effect on percentage marketable ears. We found no difference in marketable yield among plots treated from one side or both sides with an air-blast sprayer.

Abstract:
Methanol extracts of tall fescue plants (Festuca arundinacea Schreb.) infected with an endophytic fungus (Acremonium coenophialum Morgan-Jones and Gams) contain loline alkaloids which deter feeding and are toxic to insects. This study was conducted to determine the effect of several naturally-occurring and semi-synthetic loline alkaloid derivatives on insects. The influence of these compounds on the feeding behavior and weight of fall armyworm larvae, Spodoptera frugiperda Smith, and European corn borer larvae, Ostrinia nubilalis Hübner, was evaluated using two-choice, diet-incorporated feeding behavior modification bioassays. Toxicity of these compounds to greenbugs, Schizaphis graminum Rondani, was evaluated and compared with the toxicity of the insecticide nicotine sulfate. Fall armyworm larvae were more susceptible, in terms of feeding behavior modification and reduced weight gain, to specific loline derivatives than European corn borer larvae. N-acetyl loline appeared to show toxic effects, in terms of reduced larval weight in the absence of feeding behavior modification, toward both fall armyworm and European corn borer larvae. Several of the naturally-occurring loline alkaloids, namely N-formyl loline, N-acetyl loline and N-methyl loline, had LC50 values against apterous greenbug adults similar to nicotine sulfate.

Abstract:
The efficiency of border rows to prevent the adventitious presence of GM maize in non-GM maize plots was evaluated as well as the effect of the MON 810 maize of the yield and self-protection against the European corn borer. The GM maize MON 810 event was drilled at 3 locations over the Slovakia and the grain samples were collected from the neighbouring conventional maize fields. The data obtained by Real-Time PCR indicate that coexistence between GM and conventional maize is feasible and the isolation distance of 200 m (respectively 100 border rows of conventional maize) separates GM maize from the conventional one more than sufficiently. The effective isolation distance is 3–4 times greater than the actually needed. The MON 810 revealed also the highest yield and the best self-protection against European corn borer in both growing seasons with different climatic conditions.

Abstract:
The pink stem borer (PSB) (Sesamia nonagrioides Lefebvre) and the European corn borer (ECB) (Ostrinia nubilalis Hübner) are the major insect pests of corn (Zea mays L.) in Mediterranean countries, although larvae of other insects can also cause damage. The objective of this research was to evaluate the effect of sweet corn hybrids, planting time, and environment on damage by various insects. Data were recorded on the number of larvae of each of the aforementioned pests and damage produced in the ear 20 days after pollination and in the ear and stem when plants were dry. PSB was the most abundant pest, followed by ECB. Other insects, such as Mythimna unipuncta (Haworth) and Helicoverpa armigera (Hübner) were rarely found in sweet corn plants. ECB was constant over time, PSB had larger seasonal variation, and M. unipuncta and H. armigera were highly variable over time. There were significant differences among planting dates and growing cycles for damage traits in each environment. Interactions among hybrids, planting dates, and environments were significant. Dry ears were damaged more than fresh ears and stems had more larvae than ears. The economic value of the crop was seriously affected because most fresh ears had some damage, and seed production would be severely affected by PSB.

Two insecticides: Karate Zeon 050 CS, containing lambda-cyhalothrin, and Proteus 110 OD, containing thiacloprid with deltamethrin, were tested. Maize was sprayed in the second ten days of July, during the abundant occurrence of O. nubilalis larvae, which coincided with the population peak of thrips on plants. The tested active substances showed high effectiveness against thrips, but a better effect, reflected in a decrease in thrips abundance, was found for the mixture of thiacloprid with deltamethrin. The tested insecticides significantly reduced the population of thrips for up to 14 days after treatment.

AbstractThe herbivore-resistant synthetic maize BS9 (C4) was grown in three environments, namely, greenhouse with reduced UV light, greenhouse with supplemental UV light, and outside, and leaves at the three-, five-, seven-, nine-, and 10-leaf stages of development were fed to the European corn borer, Ostrinia nubilalis (Hübner). Larvae preferred younger leaves, and leaves grown under reduced UV light, in spite of the high levels of the defence compound 2,4-dihydroxy-7-methoxy-2H-1,4 benzoxazin-3 (4H)-one (DIMBOA). The low level of feeding on leaves from plants grown outside was associated with increased toughness and increased photochemically derived phenolic dimers that cross-link hemicellulose. Tender young maize plants have a low level of cell wall phenolics and depend on a toxin (DIMBOA) for defence. In older plants, DIMBOA levels are low, leaves are tough, and resistance is largely structure-based.

Abstract:
Transgenic Bt maize is a potentially important tool against insect pest in the EU and other countries. Bt maize (e.g. MON 810, Bt 11) which carries the Bt gene is highly resistant to larval feeding of European corn borer, stalk borer, and Southwestern corn borer, depending on Bt toxin (δ toxin) production. Effective measures used to fight pests may often have positive side-effects in that they may also contribute to reducing mycotoxin concentrations. A systematic review has been used for the purposes of evaluating the studies on the reduction of aflatoxins in Bt maize. According to five studies, Bt maize has significantly lower concentrations of aflatoxins than non-Bt maize hybrids, only one study has shown no significant effect of Bt maize. Other studies have shown mixed results (four studies). The results of these studies were influenced by the year of sampling or by using maize breeding lines selected for resistance to aflatoxin accumulation.

Abstract:
AbstractA degree-day model was developed for Alberta populations of Ostrinia nubilalis Hübner. Starting with overwintered fifth-instar larvae, the model calculates the temporal distribution of first- and second-instar larvae which are the stages most vulnerable to chemical suppression. Predictions from three alternative models were compared against field data from southern Alberta. Use of a standard 10°C growth threshold to calculate physiological time scales allowed predictions as accurate as those obtained using either a pooled threshold (11.4°C) calculated specifically from Alberta populations, or a model using two thresholds (12.3°C for fifth-instar larvae to adult and 10.2°C for eggs to second-instar larvae) that incorporated significant differences in growth characteristics observed among life stages. We conclude that standard thresholds are sufficient for degree-day models for northern populations of O. nubilalis. The standard model (t0 = 10°C) predicts that moth emergence will peak at ca. 145 degree-days after median pupation, and that numbers of eggs, and first- and second-instar larvae should peak at 200, 310, and 450 degree-days, respectively. Model predictions can be used to time sampling effort in support of management decisions.

Abstract:
The European corn borer (Ostrinia nubilalis) is one of the most important insect pests of maize, and has a significant impact on the production of this crop. In this work, we examined the effects of different insecticides on the antioxidative defense system of O. nubilalis larvae. The experimental setup consisted of a completely randomized block design with 4 replicates. Four experimental groups were formed as follows: control (C), indoxacarb (250 mL ha-1), chlorantraniliprole (100 mL ha-1) and the chlorantraniliprole+lambda cyhalothrin (200 mL ha-1) group. Larvae from maize stems were collected 20 days after insecticide application and the whole larvae were homogenized. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR) and glutathione S-transferase (GST), and the total amount of free SH groups were assessed. Comparison of the experimental groups showed that indoxacarb significantly affected the activities of GST, GPx and the total amount of free SH groups, while chlorantraniliprole significantly affected the activities of SOD, CAT, GST and the total amount of free SH groups, while chlorantraniliprole+lambda cyhalothrin significantly affected the activities of CAT, GST and the total amount of free SH groups. The results show that exposure to insecticides considerably affects the antioxidative defense components of the European corn borer larvae, especially chlorantraniliprole (T2).

Abstract:
AbstractThe sex pheromone components of European corn borer, Ostrinia nubilalis (Hbn.), from southern Alberta were identified in washes and extracts of abdomen tips from calling female moths. This is a Z strain population as (Z)-11- and (E)-11-tetradecenyl acetates were isolated in a ratio 100:2.4, and a corresponding synthetic blend in a ratio of 100:3 attracted males in the field. Dodecyl alcohol, tetradecyl alcohol and acetate, and (Z)-11-tetradecenol were also identified, but none of these components nor other "pheromone-like" mono-unsaturated C10 to C16 acetates had any effect on increasing the trap catches of male moths under field conditions. However, the addition of (Z)-9-dodecenyl acetate or (Z)-9-tetradecenyl acetate to the synthetic pheromone blend significantly reduced the capture of male moths, even though these compounds were not detectable in the female extracts. Pheromone blends used for monitoring the Z strain of the European corn borer must be essentially free, ca.< 0.1%, of these acetates. A commercially available, sticky-surface, delta-type trap was the most satisfactory of several tested for capturing moths under prairie conditions.

Abstract:
We compared three control strategies against European corn borer (Ostrinia nubilalis Hubner) in maize with respect to carabid beetles, beneficial epigeal arthropods. The impact of the focal treatment (insect resistant Bt maize MON 810) was compared with conventionally farmed and Trichogramma-treated plots at two sites (Prague-Ruzyně and Ivanovice na Han&eacute;) in the Czech Republic, replicated in three cropping seasons (2002&ndash;2004). The sampled assemblages were species-poor. The species were unevenly distributed in terms of their catch size &ndash; the communities were dominated by 7 (Ruzyně) or 3 (Ivanovice) species. No differences were found in species richness or species composition between treatments, seasons or sites, suggesting no effect of planting transgenic insect resistant Bt maize MON 810 on the assemblages of carabid beetles in the study fields. &nbsp;
