... Drawbacks of public opposition to novel or emerging technologies may include market failures such as the limited uptake of an innovation, as well as discontinued public investments and lack of political and regulatory endorsement. Similar drawbacks can be found in the controversial case of public opposition to genetically-modified organisms (GMOs) in the agricultural sector (Blancke et al., 2015), anti-nuclear energy movements in major EU countries (Jahn and Korolczuk, 2012;Gong et al., 2022), as well as vaccine opposition during the COVID-19 pandemic (Bonnevie et al., 2021;Escario et al., 2022). ...
... From 2011 to 2020, global surface temperature rose by 1.09℃ compared to the Industrial Revolution, with about 1.07℃ of the warming caused by human activities. Along with the increasing severity of frequent extreme weather and global warming, climate governance and global cooperation on CO 2 emission mitigation has emerged as an urgent concern (Gong et al., 2022;Wei et al., 2021a). The Paris Agreement was signed by nearly 200 countries and regions in December 2015. ...
... The Paris Agreement was signed by nearly 200 countries and regions in December 2015. It determined the middle-and short-term emission reduction objectives for all countries in the form of intended nationally determined contributions and encouraged all countries, particularly developing ones, to dedicate coordinated commitments in tackling climate change and achieve the goal of balancing development with CO2 emission mitigation (Liu & Wen, 2018;Meng et al., 2022;Wei et al., 2021b). Therefore, it is imperative to measure the relations (i.e., the degree of coupling coordination) between socio-economy and carbon emission systems. ...
... The underlying conjecture of our analysis was that, for countries that implemented the ETS before they crossed the turning point, the ETS would reduce the positive coefficient between the GDP per capita and the carbon emissions per capita. However, for countries that implemented the ETS after crossing the turning point, a more negative relationship would occur between the GDP per capita and carbon emissions per capita 43,48,49,[51][52][53] . ...
... Freitas et al. [56] observed a similar decrease in THC only 48 h after inoculating conidia of B. bassiana CG 206 into the tick, Rhipicephalus microplus. Wang et al. [57] exposed Spodoptera litura larvae to Metarhizium rileyi conidia by injection or immersion. They observed that the reduction in hemocyte concentration was slower in larvae immersed (~ 20 h) than injected (~ 2 h). ...

... In the first dozen years of this century, robust genetic manipulation technologies including Agrobacterium tumefaciens-mediated fungal transformation and gene deletion based on homologous recombination had been developed for the Metarhizium fungi (Fang et al., 2006;Wang and St Leger, 2006;Xu et al., 2014;Su et al., 2018), and the genomes of Metarhizium species, M. robertsii, and M. acridum, were sequenced (Gao et al., 2011;Hu et al., 2014). This has been significantly speeding up the research on molecular mechanisms underlying insect infection and development by the Metarhizium fungi. ...
... Plusieurs organismes mondiales et travaux de recherches ont utilisé les services de webmapping pour publier leurs recherches et augmenter la conscience sur l'exigence d'une politique mondiale adéquate pour assurer la durabilité de nos ressources exemple Le Web GIS joue un rôle important dans l'élimination des barrières où le coût limite l'utilisation des données spatiales publiques et l'accès aux outils SIG (Golhani et al. 2015). Cet outil peut servir dans l'atténuation, la gestion, le suivi de la production agricole, l'évaluation de la vulnérabilité et des risques, la lutte contre les ravageurs, la surveillance de l'agriculture de précision, la climatologie, la gestion des ressources en eau et du sol et le rétablissement après une catastrophe (Bao et al.,2011 ;Zouaghui et al, 2015 ;Juhász et al., 2016 ;Yao et al,2017 ;Pan et al.,2017 ;Perovic et al.,2016). ...
