“…Consumption rates for Octotoma scabripennis were higher than O. Championi when given CO 2 -grown foliage under lower temperature (Johns et al, 2003). Research done by Chen et al (2005) revealed that fecundity of Aphis gossypii was increased through successive generation with increasing of CO 2 concentration.…”

Abstract. Tenebrio molitor has never been used as a model species for studying global warming effects. The objectives of this study were to measure the larval development and genetics of T. molitor under a free air CO 2 enrichment (FACE) system, open roof ventilation greenhouse system (ORVS) and a rearing room system (RR). The correlation coefficient analysis showed that the head width: body length was the best character to measure the development (0.465, 0.940 and 0.893) in all systems. Our results show that there were no significant changes in the larvae samples under RR condition, however, slight and moderate changes were observed under FACE and ORVS. Neighbour-joining analysis using cytochrome c oxidase subunit I sequence revealed the genetic data parallel with the results of the correlation coefficient. The FACE F1 progeny showed the slowest development (0.080±0.018 mm) during 0-14 days of larval development, while the most rapid before pupation occurred in the ORVS F1 (0.1205±0.0028 mm). No significant differences were noted between the systems for 0-14 days and before pupation, except for RR F1 vs ORVS F1 and ORVS F1 vs FACE F1 (p = 0.000, p = 0.002). These data can be used to clarify the changes in T. molitor due to global warming effects, as CO 2 could be one of the factors affecting the larval development.

“…Early onset of infestation by H. armigera in cotton and pulses in Northern India is one such example [8,21]. Lower foliar nitrogen due to elevated CO 2 causes an increase in food consumption by the herbivores up to 40 percent, and unusually severe drought appears to cause herbivore populations to explode [43,44]. Further, the lower N content reduces the overall protein content of the plant [43][44][45][46].…”

Climate change is a major concern for agriculture globally. Dynamic climatic parameters including increased temperature and carbon dioxide have greatly affected crop production. As a consequence of climatic uncertainties, new insect pests have emerged, the crop cultivation practices have changed, and drought and floods have created havoc around the globe. Besides, plant and insecticidal resistance against insects and diseases has got compromised, the diversity and abundance of arthropods has changed, geographical ranges of insect pests have extended far beyond their existing limits and new biotypes have evolved. All these have led to the reduced efficacy of crop protection technologies, huge crop losses, thereby, food insecurity. Although concerted efforts have been made and simulation models have been developed to mitigate the climate change effects on plants, still, most simulation models fail to account for losses due to pests, weeds and diseases. In addition, the monitoring data of insect pests are not available in most of the developing countries and the software models developed for prediction analysis are not effective against insect-pests. This review highlights the possible impacts of climate change on phytophagous insects, chemical ecology, and plant pest interactions leading to food insecurity and the strategies thereof.

“…The direct "fertilizing" effects of enriched atmospheric CO 2 on plant growth, physiology and community structure have been well documented (Curtis and Wang 1998;Luo et al 1999). In general, elevated CO 2 increases biomass (Chen et al 2005b), reduces foliar nitrogen Wu et al 2006) and increases C:N ratio for most plants, especially C 3 crops (Johns and Hughus 2002 concentration (N m ) and specific leaf area (SLA) were decreased through a retrospective synthesis across 62 species under elevated CO 2 . Paul et al (2002) found that elevated CO 2 significantly increased aboveground biomass, but had no effect on shoot density.…”

A field study was carried out to quantify plant growth and the foliar chemistry of transgenic Bacillus thuringiensis (Bt) cotton (cv. GK-12) exposed to ambient CO 2 and elevated (double-ambient) CO 2 for different lengths of time (1, 2 and 3 months) in 2004 and 2005. The results indicated that CO 2 levels significantly affected plant height, leaf area per plant and leaf chemistry of transgenic Bt cotton. Significantly, higher plant height and leaf area per plant were observed after cotton plants that were grown in elevated CO 2 were compared with plants grown in ambient CO 2 for 1, 2 and 3 months in the investigation. Simultaneously, significant interaction between CO 2 level × investigating year was observed in leaf area per plant. Moreover, foliar total amino acids were increased by 14%, 13%, 11% and 12%, 14%, 10% in transgenic Bt cotton after exposed to elevated CO 2 for 1, 2 or 3 months compared with ambient CO 2 in 2004 and 2005, respectively. Condensed tannin occurrence increased by 17%, 11%, 9% in 2004 and 12%, 11%, 9% in 2005 in transgenic Bt cotton after being exposed to elevated CO 2 for 1, 2 or 3 months compared with ambient CO 2 for the same time. However, Bt toxin decreased by 3.0%, 2.9%, 3.1% and 2.4%, 2.5%, 2.9% in transgenic Bt cotton after exposed to elevated CO 2 for 1, 2 or 3 months compared with ambient CO 2 for same time in 2004 and 2005, respectively. Furthermore, there was prominent interaction on the foliar total amino acids between the CO 2 level and the time of cotton plant being exposed to elevated CO 2 . It is presumed that elevated CO 2 can alter the plant growth and hence ultimately the phenotype allocation to foliar chemistical components of transgenic Bt cotton, which may in turn, affect the plant-herbivore interactions.Key words: elevated CO 2 ; growth; leaf chemistry; open-top chamber; transgenic Bt cotton.Wu G, Chen FJ, Ge F, Sun YC (2007).

Available online at www.blackwell-synergy.com/links/toc/jipb, www.jipb.netThe current atmospheric carbon dioxide (CO 2 ) level is expected to increase from about 350 to 650 part per million by These changes in atmospheric CO 2 are likely to have a direct influence on plant growth and foliar chemistry.
