“…Farmers' knowledge of diseases are well documented for cash crops, such as cotton (Ochou et al, 1998), rice (Norton and Rajotte, 1999;Price, 2001;Rubia et al, 1996) and food crops such as millet (Tanzubil and Yakubu, 1997;Youm and Owusu, 1998), beans (Trutmann et al, 1996), cowpea (Bottenberg, 1995), and vegetables (Chitere and Omolo, 1993;Norton and Rajotte, 1999;Obopile et al, 2008). However, similar documentation for sweet potatoes is scant and not up-to-date (Bashaasha et al, 1995;Gibson et al, 2000;Kapinga et al, 1995).…”

“…Virus diseases alone can lead to sweet potato yield reductions in the range between 56% and 98% (Mukasa et al, 2003). Thus understanding farmers' knowledge related to perceptions of crop diseases, practices of pests, and their management is essential for the development of management strategies, supported by government and non-governmental organizations, which cater to farmers' needs and have a high probability of being adopted by the intended users (Chitere and Omolo, 1993;Rubia et al, 1996;Tanzubil and Yakubu, 1997). Oswald et al (2009) assert that in Africa, weevils and viruses are crucial biological factors that hinder both sweet potato quality and yield.…”

“…Average taxon-specific saliency was 28.0±19.4% (n=15 studies), ranging from an average of 5.8% in Philippine rice producers that enumerated pests belonging to 4 arthropod orders (Litsinger et al 2009), to 78.8% in Indonesian rice farmers that listed pests belonging to 2 arthropod orders (Rubia et al 1996). (1) perceived importance of a given insect order, in terms of it containing key herbivores including pests targets; (2) up to 5 insect families that are perceived as key herbivores; (3) percent farmers that free-list herbivores belonging to a given family; (4) percent farmers that perceive particular herbivores as pests, deliberately targeting them in management interventions.…”

“…Approximately 70% farmers (n=17 studies; 1088 informants) attributed high levels of importance to insect pests, signaling that pest attack regularly leads to e.g. production losses of 6 t/ha (Rubia et al 1996), yield losses up to 90% (Munyuli et al 2017) and related economic impacts of over $400/ha (Heong and Escalada 1999). Yet, only 47.5±25.0% farmers possessed moderate to good knowledge of the biology and morphology of key pests (n=4 studies), and 38.3±18.0% of these had moderate to good knowledge of their ecology and feeding habits (n=5 studies).…”

Nearly 2.5 billion smallholders cultivate the world’s arable land, strategically positioned to tackle multiple Anthropocene challenges. When consciously adopting ecologically-based pest management practices, they can improve resource use efficiency, slow biodiversity loss, curtail environmental pollution and safeguard human health. Yet, the effective implementation of knowledge-intensive management practices requires underlying ecological concepts to be well-understood. Here, drawing upon published social science research spanning 1910–2016, we illuminate deficiencies in the world’s farmers’ ecological literacy and in their valuation of insect-mediated ecosystem services. Though tribal people and indigenous folk possess sophisticated knowledge of insects that occur within farm settings, contemporary farmers on average know a mere 1.9–2.3 pestiferous herbivores and 0.5–0.9 pest-killing organisms (out of a respective 8 and 3 taxa) in a particular crop or cropping system. Ecosystem services such as biological pest control are annually worth hundreds of dollars ha−1 but remain unknown to nearly 70% of farmers globally. Also, agricultural systems with deficient ecological literacy tend to foster a greater dependency upon chemically-synthesized pesticides. If this ‘cognitive handicap’ can be remediated, farmers could become agro-biodiversity stewards and champions in redressing multiple aspects of global environmental change.

Participatory plant breeding approach for host plant resistance to bean fly in common bean under semi-arid Kenya conditions

et al. 2009

Common bean (Phaseolus vulgaris L.) is the most important legume crop in Kenya. It is cultivated across a wide range of agro-ecologies which include high potential and marginal areas. Eastern Kenya alone, largely semi-arid, accounts for 35% of the country's total bean production. Bean farmers mainly small-scale have limited access to quality seed, chemical pesticides and fertilizer. Therefore, bean yield under on-farm conditions still remains below 500 kg ha -1 while the potential is about 1,200 kg ha -1 under semi-arid conditions. To asses the farmers' views on bean varieties and a key insect pest and associated constraints contributing to yield loss, research was undertaken. The research included survey to quantify the yield loss and Participatory Rural Appraisal to determine the level of adoption and criteria for variety choice in semi-arid eastern Kenya (SAEK). The results show that farmers consider drought and insect pest problems as main causes for low yields. The adoption rate for improved varieties is high but self sufficiency in beans stands at 23% in the dry transitional (DT) agro-ecology and at 18% in the dry mid-altitude (DM) agro-ecology, respectively. This could be attributed to low adaptability since most of the improved varieties grown were selected for high potential areas but now found in marginal areas. Drought, earliness, yield stability, and insect pest resistance are the main reasons for choice of varieties by farmers. Bean fly (Ophiomyia sp.) was identified as one of the key crop pests of beans limiting yield. Besides, African bollworm (Helicoverpa armigera) and bean aphid (Aphis fabae) were ranked higher. Due to limitations of the conventional breeding approach, a participatory plant breeding approach is suggested so as to provide an opportunity to develop insect pest resistant varieties adapted to the SAEK region.
