Direct and indirect effects of planting density, nitrogenous fertilizer and host plant resistance on rice herbivores and their natural enemies
Horgan, Finbarr G.; Crisol-Martínez, Eduardo; Stuart, Alexander M.; Villegas, James M.; Peñalver-Cruz, Ainara; Mundaca-Ortega, Enrique; Pérez, Marivic O.; Bernal, Carmencita C.; Almazan, Maria Liberty P.; Fame Ramal, Angelee (2022)In rice ecosystems, seeding densities can be adjusted to compensate for lower nitrogen levels that reduce GHG emissions, or to increase farm profitability. However, density-induced changes to plant anatomy could affect ...

Diversified rice farms with vegetable plots and flower strips are associated with fewer pesticide applications in the Philippines
Horgan, Finbarr G.; Mundaca-Ortega, Enrique; Hadi, Buyung A. R.; Crisol-Martínez, Eduardo (2023)Ecological engineering is defined as the design of sustainable ecosystems for the benefit of both human society and the environment. In Southeast Asia, researchers have applied ecological engineering by diversifying farms ...

Dung removal increases under higher dung beetle functional diversity regardless of grazing intensification
Ari Noriega, Jorge; Hortal, Joaquín; deCastro-Arrazola, Indradatta; Alves-Martins, Fernanda; Ortega, Jean C. G.; Bini, Luis Mauricio; Andrew, Nigel R.; Arellano, Lucrecia; Beynon, Sarah; Davis, Adrian L. V.; Favila, Mario E.; Floate, Kevin D.; Horgan, Finbarr G.; Menéndez, Rosa; Milotic, Tanja; Nervo, Beatrice; Palestrini, Claudia; Rolando, Antonio; Scholtz, Clarke H.; Senyüz, Yakup; Wassmer, Thomas; Ádam, Réka; Araújo, Cristina de O.; Barragan-Ramírez, José Luis; Santos, Ana M. C. (2023)Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, ...

Effects of intraspecific competition and larval size on bioconversion of apple pomace inoculated with black soldier fly
Horgan, Finbarr G.; Launders, Michael; Mundaca-Ortega, Enrique; Crisol-Martínez, Eduardo (2022)Waste from apple juice and cider industries (pomace) compares poorly against spent grains and other relatively high-nutrient wastes as a substrate for bioconversion by the black soldier fly (BSF: Hermetia illucens). However, ...

Elevated temperatures diminish the effects of a highly resistant rice variety on the brown planthopper
Horgan, Finbarr G.; Arida, Arriza; Ardestani, Goli; Almazan, Maria Liberty P. (2021)This study compares the effects of temperature (constant at 15, 20, 25, 30 and 35 °C) on adult longevity, oviposition, and nymph development of the brown planthopper, Nilaparvata lugens, on susceptible and resistant rice ...

Escaping the lock-in to pesticide use: do vietnamese farmers respond to flower strips as a restoration practice or pest management action?
Horgan, Finbarr G.; Vu, Quynh; Mundaca-Ortega, Enrique; Dabholkar, Shweta; Davis, Mark; Settele, Josef; Crisol-Martínez, Eduardo (2023)Ecological engineering using linear flower strips is proposed as an alternative to insecticide-based rice pest management. However, its success depends on farmers’ appreciations of related interventions as part of an ...

Pollination supply models from a local to global scale
Giménez-García, Angel; Allen-Perkins, Alfonso; Bartomeus, Ignasi; Balbi, Stefano; Knapp, Jessica L.; Hevia, Violeta; Woodcock, Ben Alex; Smagghe, Guy; Miñarro, Marcos; Eeraerts, Maxime; Colville, Jonathan F.; Hipólito, Juliana; Cavigliasso, Pablo; Nates-Parra, Guiomar; Herrera, José M.; Cusser, Sarah; Simmons, Benno I.; Wolters, Volkmar; Jha, Shalene; Freitas, Breno M.; Horgan, Finbarr G.; Artz, Derek R.; Sidhu, C. Sheena; Otieno, Mark; Boreux, Virginie; Biddinger, David J.; Klein, Alexandra-Maria; Joshi, Neelendra K.; Stewart, Rebecca I. A.; Albrecht, Matthias; Nicholson, Charlie C.; O'Reilly, Alison D.; Crowder, David William; Burns, Katherine L. W.; Nabaes Jodar, Diego Nicolás; Garibaldi, Lucas Alejandro; Sutter, Louis; Dupont, Yoko L.; Dalsgaard, Bo; da Encarnação Coutinho, Jeferson Gabriel; Lázaro, Amparo; Andersson, Georg K. S.; Raine, Nigel E.; Krishnan, Smitha; Dainese, Matteo; van der Werf, Wopke; Smith, Henrik G.; Magrach, Ainhoa (2023)Mechanistic models simulate the habitat preferences and foraging behaviour of pollinators, while data-driven models associate georeferenced variables with real observations. Here, we test these two approaches to predict ...

Potential impact of future climates on rice production in Ecuador determined using kobayashi’s ‘very simple model’
Portalanza, Diego; Horgan, Finbarr G.; Pohlmann, Valeria; Vianna Cuadra, Santiago; Torres-Ulloa, Malena; Alava, Eduardo; Ferraz, Simone; Durigon, Angelica (2022)Rice (Oryza sativa L.) is the main staple food of more than 50% of the world’s population. However, global production may need to increase by more than 70% before 2050 to meet global food requirements despite increasing ...

Prospects for integrating augmentative and conservation biological control of leaffolders and stemborers in rice
Babendreier, Dirk; Tang, Rui; Horgan, Finbarr G. (2022)Possibilities to combine augmentative biological control using Trichogramma spp. egg parasitoids and conservation biological control through habitat manipulation, for the management of rice leaffolder and rice stemborer ...

Slowing virulence adaptation in Asian rice planthoppers through migration-based deployment of resistance genes
Horgan, Finbarr G. (2023)Advances in molecular biology have accelerated rice breeding for resistance to Asian planthoppers. However, experience shows that planthoppers quickly adapt to resistance in tropical overwintering areas. With only limited ...

Spent coffee grounds applied as a top-dressing or incorporated into the soil can improve plant growth while reducing slug herbivory
Horgan, Finbarr G.; Floyd, Dylan; Mundaca-Ortega, Enrique; Crisol-Martínez, Eduardo (2022)Between 8 and 15 million tons of spent coffee grounds (SCG) are produced as global waste each year. To reduce waste to landfill, SCG are proposed as a carbon and nutrient source for degraded soils. SCG contain caffeine and ...
