“…The literature available mostly analyse the effects of shaded agroforestry practices [9,[43][44][45] and unshaded agroforestry practices [46,47] on the environment separately. To our knowledge, innovation-induced agroforestry, including its waste management studies, are seldom researched in developing countries.…”

Drawing on the awareness of consequence literature, this paper unpacks how the awareness of the consequences of full-sun cocoa production can encourage farmers to adopt shaded cocoa agroforestry that preserves the land and favours better cocoa farm waste management. Using Ghana as a case study, the paper provides distinctive insights on how shaded cocoa agroforestry systems provide sustainable yields in the medium- to long-term, relative to unshaded systems. We also find that cocoa farmers’ awareness of consequences about the effects of undertaking unshaded cocoa production could make individual farmers exhibit pro-environmental behaviour, leading to the adoption of cocoa agroforestry systems that help preserve soil fertility and improve waste management. We recommend that the utilization of awareness of consequence protocols, coupled with the efficient diffusion of information on the benefits of agroforestry in terms of waste management and environmental improvements to the cocoa farmers, could increase the adoption of shaded cocoa production regimes in Ghana.

“…The mirid bugs, in particular, consist of 40 species under Family Miridae that cause damage to cacao. Only a few, however, cause significant economic loss that can range between 30 to 40% (Entwhistle, 1972;Mahob et al, 2020). The mirid bug Helopeltis bakeri Poppius (Hemiptera: Miridae) is considered a major insect pest of cacao in the Philippines particularly in Luzon.…”

β-caryophyllene as an attractant for the cacao mirid bug, Helopeltis bakeri Poppius (Hemiptera: Miridae), and chemodiversity of its host plant volatiles

et al. 2023

The cacao mirid bug, Helopeltis bakeri, is a major insect pest of cacao in the Philippines. It feeds on pods causing puncture wounds that become necrotic lesions and may lead eventually to pod abortion. There is currently no semiochemical-based system developed for the monitoring and control of H. bakeri. Here, we report a kairomone identified from host plants of H. bakeri as a potential attractant. Volatile components were extracted using solid-phase microextraction (100-µm polydimethylsiloxane) and analyzed by gas chromatography - mass spectrometry. Chemodiversity analysis considering compound richness, evenness, and disparity showed similar phytochemical diversity among the six host plants, suggesting that chemodiversity is a factor in the host selection behavior of H. bakeri. Comparison of volatiles revealed that β-caryophyllene was present in all host plants. Using a wind tunnel, an impregnated lure containing 90 µg β-caryophyllene showed the highest attraction to adult H. bakeri. The results show the potential of β-caryophyllene as attractant that can be used in the development of kairomone-based trapping systems for H. bakeri as part of a holistic integrated pest management system for cacao.
