Evaluation of alternatives to synthetic pesticides under small-scale farmer-managed grain storage conditions

The Fall Armyworm and Larger Grain Borer Pest Invasions in Africa: Drivers, Impacts and Implications for Food Systems

“…The use of entomopathogenic fungi, such as Beauveria bassiana , has been reported to be effective in controlling P. truncatus infestation in stored maize, though it would require periodic re-treatment after every 4 weeks to maximise grain protection during prolonged storage [ 246 ]. Combinations of enhanced diatomaceous earths (DEs) and natural products such as spinosad or low dose pyrethroids have also been proven effective both in the laboratory and in small scale grain storage systems [ 247 , 248 ] but are not available on the market. Host plant resistance though the selection and use of resistant varieties can be integrated with other control methods, such as synthetic pesticides, to improve P. truncatus management [ 51 ].…”

“…Na consulta, foi utilizado o operador boleano "AND" para adição de ocorrências com os termos em inglês e dispostos em "aspas", toxicity AND "Sitophilus zeamais"; repellency AND "Sitophilus zeamais"; "Sitophilus zeamais" AND "essential oil(s)"; "Sitophilus zeamais" AND "Citrus TOFEL et al, 2016;TOFEL et al, 2017) e dentre os métodos alternativos mais utilizados estão a utilização de terra de diatomáceas (JAIROCE et al, 2016;MACHEKANO et al, 2017;BOHINC et al, 2018;WILLE et al, 2019;MACHEKANO et al, 2019;ZHANDA et al, 2020;NWAUBANI et al, 2020), os inseticidas deltametrina e espinosade (MACHEKANO et al, 2017;KAVALLIERATOS et al, 2017;VÉLEZ et al, 2017;VELEZ et al, 2019;MACHEKANO et al, 2019), além do composto organossulfurado isotiocianato de alila, principal componente do óleo de mostarda (FREITAS et al, 2016;ZHANG et al, 2016;ZHANG et al, 2017).…”

Review: Presence, distribution and current pesticides used in Spanish agricultural practices

“…With this in mind, there is a growing interest in the development of new formulas for the chemical pesticides used in order to make them more effective and in such a way that their dose can be reduced as to lessen their environmental impact while achieving the same beneficial effect. Thus, Machekano et al (2019) demonstrated an enhanced effect of low doses of certain pesticides such as Deltamethrin or Spinosad, when combined with diatomaceous earths (DEs). The combination of pesticides with key natural enemies (NE) as well as controlling the vectors of certain virus transmissions to provide a second line of defense under IPM has been evaluated (Dáder et al, 2020;Ruiz Garcia and Janssen, 2020), Moreover, investigating synergistic effects of certain viruses with insecticides for IPM is of interest (Dáder et al, 2020), and comparing conventional vs. ecological practices such as those carried out by Carpio et al (2019) against the olive fly in Andalusia which was comprised of treatments using 40 % Dimethoate plus hydrolyzed protein (conventional olive grove) or 0.024 % Spinosad.…”
