IPM strategy for rodent control in storage facilities

Abstract

Abstract:The fundamental idea of IPM is to put nature's own regulatory mechanisms to maximum use in order to prevent damage, which is in the best interest of manufacturers, society at large and the environment. However, Haines (2000) assessed stored products IPM still insufficiently developed at the end of the 20th century. Support to IPM development in stored agricultural products is the use of natural compounds to control rodent pests. One of such compounds is cellulose, whose mode of action differs from the modes of other rodenticide active ingredients. As resistance to I and II generation anticoagulant rodenticides has been reported worldwide, we have introduced for the first time anywhere in the world a rodenticide based on Se (0.1% sodium selenite) with a mode of action based on the replacement of SH groups of functional enzymes with S-S groups. We also tested products based on vitamin D3 with a known mechanism of action.The new Se-based products achieved good efficacy against rat (91.10 % and 87.50 %) and mouse (97.60% and 98.40%), and cellulose-based product against mouse (91.66%), compared to products based on vitamin D3 in rat (90.00% and 90.30%) and mouse control (98.60% and 98.2%), bromadiolone in rat (93.80% and 90.7%) and mouse control (92.86% and 91.9%) and brodifacoum in mouse control (97.06%).The products based on Se, vitamine D3 and cellulose have good toxicological and ecological properties and the fact that there have been no known cases of resistance make them recommendable for use against rodents in storage facilities.

Sodium selenite as a new rodenticide

“…Applying standard EPPO (2004a) methodology, trials were conducted to test the efficacy of several formulations of commercial products with 0.1% sodium selenite and 0.005% bromadiolone in the field against field rodents (Vukša et al, 2009;Jokić et al, 2010;Jokić et al, 2012). Common voles and striped field mice were found predominating, depending on locality, plant crop and its growth stage, and evaluation that was conducted either by trapping or by visual observation of characteristic signs.…”

“…Over a period of eight years, different formulations of commercial products containing 0.1 % sodium selenite and 0.005% bromadiolone have been experimentally tested in mills, mixing and storage facilities (Vukša et al, 2007;Đedović et al, 2011;Jokić et al, 2011a;Đedović et al, 2012) in order to determine their efficacy in controlling commensal rodents.…”

“…Hitherto research has mostly focused on determining the properties of the most frequent organic and inorganic forms of selenium occurring in nature or its synthetic and formulated products. Our own experiments have been conducted to test baits with 0.1% sodium selenite content in the field (Vukša et al, 2009;Jokić et al, 2010;Jokić et al, 2012), in warehouses (Vukša et al, 2007;Đedović et al, 2011;Jokić et al, 2011a;Đedović et al, 2012) and in the laboratory (Vukša et al, 2006;Jokić et al, 2011b;Jacević et al, 2011). The focus of our present research was on the advantages and deficiencies of sodium selenite as a rodenticide based on its ecotoxicological parameters and other properties of baits containing 0.1% sodium selenite.…”
