“…In general, those and other studies showed kaolin as an effective substance in reducing the population of several groups of pests, such as Hemiptera (Daniel et al, 2005;Alavo and Abagli, 2011;Martinou et al, 2014), Lepidoptera (Showler, 2003;Sackett et al, 2007), Diptera (Mazor and Erez, 2004;Pascual et al, 2010) and Coleoptera (Silva and Ramalho, 2012).
