Effects of Color Attributes on Trap Capture Rates of Chrysobothris femorata (Coleoptera: Buprestidae) and Related Species

Chrysobothris spp. (Coleoptera: Buprestidae) and other closely related buprestids are common pests of fruit, shade, and nut trees in the United States. Many Chrysobothris spp., including Chrysobothris femorata, are polyphagous herbivores. Their wide host range leads to the destruction of numerous tree species in nurseries and orchards. Although problems caused by Chrysobothris are well known, there are no reliable monitoring methods to estimate local populations before substantial damage occurs. Other buprestid populations have been effectively estimated using colored sticky traps to capture beetles. However, the attraction of Chrysobothris to specific color attributes has not been directly assessed. A multi-color trapping system was utilized to determine color attraction of Chrysobothris spp. Specific color attributes (lightness [L*], red to green [a*], blue to yellow [b*], chroma [C*], hue [h*], and peak reflectance [PR]) were then evaluated to determine beetle responses. In initial experiments with mostly primary colors, Chrysobothris were most attracted to traps with red coloration. Thus, additional experiments were performed using a range of trap colors with red reflectance values. Among these red reflectance colors, it was determined that the violet range of the electromagnetic spectrum had greater attractance to Chrysobothris. Additionally, Chrysobothris attraction correlated with hue and b*, suggesting a preference for traps with hues between red to blue. However, males and females of some Chrysobothris species showed differentiated responses. These findings provide information on visual stimulants that can be used in Chrysobothris trapping and management. Furthermore, this information can be used in conjunction with ecological theory to understand host-location methods of Chrysobothris

Stealth-spectacles: the discursive waves of the nuclear Asian seascape

When compared to the bombast of nuclear tests, nuclear submarines come with the relatively quiet fantasy of victory-to-come against neighbouring nuclear adversaries. Such political expressions are making their mark in Indian popular culture that hitherto had little commentary to offer on submarines. Outlets such as film and digital media on submarines rest on an aporia that resonates across the pleats and folds of secrecy and publicity: there is a felt need to keep covert underwater vessels under wraps, yet also an irrepressible desire to glorify the technological achievement and political posturings enabled by thesecond strike capability of a nuclear armed and powered submarine. Highlighting the tensile allure of both stealth and spectacle, the article considers the ways submarines make a mark in Indian audio-visual and digital media alongside the affective resonance of submarines more widely. By understanding their hegemonic dynamics, we can begin to raise questions about the ongoing nuclearisation of the Asian region and neighbouring arterial seas described here as the Asian seascape

Outer space technopolitics and postcolonial modernity in Kazakhstan

This is the final version. Available on open access from Routledge via the DOI in this recordThis article examines the role of outer space technopolitics in post-Soviet Kazakhstan. It explores how outer space, the technological artefact of global relevance, works as a postcolonial fetish of modernity that is called upon to produce what it represents, i.e. the reality of a technologically advanced Kazakh nation. The article shows that in its project of becoming a spacefaring nation the country reiterates major incentives that have motivated nuclear and space programme development in the postcolonial context of the Global South. The article explores how collaboration with Russia allows Kazakhstan to claim its share in the Soviet space legacy rather than to distance itself from it. It then traces the rise of a new internationalism in the Kazakhstani space programme outside the post-Soviet context. The article contributes to the debate on postcolonial techonopolitics and shows how outer space has been used to enhance the conventional domain of postcolonial national ideologies – nativism and tradition – with technology and science. Finally, the article depicts how the growing resistance to the space programme among Kazakh civil society groups reveals a close association of the environmental agenda with an “eco-nationalism” permeated by a profoundly anti-imperial and, ultimately, antiauthoritarian political discourse
