“…Therefore, it is clear that certain pests are more likely to afflict particular crop types. Our findings are consistent with other studies where farmers have reported rodents to be very problematic pests for rice production (Tuan et al, 2003;Brown et al, 2008;Stuart et al, 2011), insects for vegetable crops (Obopile et al, 2008;Abang et al, 2014;Nyangau et al, 2020), and fungal infections for fruit crops (Ann et al, 1999;Amata et al, 2009;Lahlali et al, 2021).…”

Pests cause devastating losses on agricultural industries worldwide. Common pest management practices include using chemical products. The efficacy of these toxins remains inconclusive, however, and their application can have adverse effects on non-target wildlife from both direct and indirect exposure. In parts of Taiwan, threatened species may be at considerable risk since they inhabit areas with agricultural activity. Therefore, in this exploratory study, we surveyed farmers using a structured questionnaire in Miaoli County, northwestern Taiwan, in agricultural areas that overlap with the distribution of the locally endangered leopard cat (Prionailurus bengalensis), whose diet comprises a high proportion of rodents. Based on the completed questionnaires of 126 farmers, the majority stated they use at least two different types of chemical pest control products. Furthermore, pest-related factors, such as perceived worst pest, total pest problem, and number of pests, were all important determinants for pest control behavior. Farmers whose crops were afflicted by rodents were more likely to use rodenticides in addition to other types of pesticides. These agricultural areas, which include vegetable cropland, pose a risk of poisoning to non-target wildlife, like the leopard cat, through various exposure pathways including consumption of contaminated prey and dermal contact. Farmers also expressed support to use less chemical-based pest products, but not to stop using them entirely. Therefore, there may be opportunities to implement ecologically based control practices to mitigate risks to wildlife and promote increased environmental health.

“…Registrations for some biopesticide AIs in countries in Asia have moved more quickly. The lower number of new registrations could be due to registration costs, regulatory hurdles or inaction from manufacturers due to their perception of the size of the pesticide market (Constantine et al, 2020;Nyangau et al, 2020).…”

“…According to Carson [17], the method is not appropriate since it requires a large sample size and is not statistically efficient. Studies have illustrated the effectiveness of the double-bounded model since it incorporates more information about the respondents' willingness to pay (WTP), and therefore providing efficient estimates [11,18,19]. The model offers a second bid, either higher or lower depending on the respondent's first response, unlike the single-bounded model [17].…”

“…ICIPE 20 is an entomopathogenic fungus: Metarhizium anisopliae Sorokin (1883) isolated from soil in Migori county in Kenya, in 1989. The isolate has been demonstrated to cause between 82-92% mortality in T. absoluta larvae and adult moths and is highly compatible with the pheromone lures currently being used for monitoring and mass trapping moths [11]. The isolate if commercialized as a biopesticide will form an integral component of T. absoluta Integrated Pest Management (IPM) as it can be sprayed on the ground, and on the crop to kill both larvae and adult moths of the pest.…”

Agro-Dealers’ Knowledge, Perception, and Willingness to Stock a Fungal-Based Biopesticide (ICIPE 20) for Management of Tuta absoluta in Kenya

In sub-Saharan Africa (SSA), tomato is an economically important crop that contributes not only to employment and income, but also food security. Like the rest of the SSA countries, tomato production in Kenya is constrained mainly by pests and diseases, key among them being the tomato leaf miner (Tuta absoluta), which can cause 80–100% losses if not properly managed. To suppress this pest, the International Centre of Insect Physiology and Ecology (ICIPE) and partners are introducing a fungal-based biopesticide (ICIPE 20) in an Integrated Pest Management (IPM) approach as a sustainable alternative to the sole use of synthetic pesticides. This study was carried out before the introduction of the biopesticide to assess its commercial feasibility among agro-dealers, using Kirinyaga County in Kenya where tomato production is predominant, as the study area. Specifically, the study assessed the knowledge, perception, and willingness to stock biopesticide using a market survey involving 141 agro-dealers. Successful commercialization of a new product is assumed to be the cumulative result of traders’ and buyers’ knowledge and perceptions about the product. The results show that a higher proportion of agro-dealers were willing to pay for ICIPE 20 at a higher price than Coragen®, the most popular insecticide for management of T. absoluta. The regression analysis revealed that individual characteristics such as age, education, access to social networks and credit facilities, and information are correlated to the agro-dealer’s knowledge, perception, and willingness to stock the biopesticide. Training agro-dealers may promote greater uptake of the biopesticides through enhancing their knowledge and perception towards the effectiveness of the product.
