Abstract

BackgroundTribolium castaneum (Herbst) is a harmful pest of stored grain and flour-based products in tropical and subtropical region. In the present study, rhizome of Drynaria quercifolia (J. Smith) was evaluated for pesticidal and pest repellency activities against T. castaneum, using surface film method and filter paper disc method, respectively. In addition, activity of the isolated compound 3,4-dihydroxybenzoic acid was evaluated against the pest.ResultsChloroform soluble fraction of ethanol extract of rhizome of D. quercifolia showed significant pesticidal activity at doses 0.88 to 1.77 mg/cm2 and significant pest repellency activity at doses 0.94 to 0.23 mg/cm2. No pesticidal and pest repellency activity was found for petroleum ether, ethyl acetate and methanol soluble fractions of ethanol extract as well as for 3,4-dihydroxybenzoic acid.ConclusionConsidering our findings it can be concluded that chloroform soluble fraction of rhizome of D. quercifolia is useful in controlling T. castaneum of stored grain and flour-based products.Electronic supplementary materialThe online version of this article (doi:10.1186/0717-6287-47-51) contains supplementary material, which is available to authorized users.

Summary

Introduction

Tribolium castaneum (Herbst) is a harmful pest of stored grain and flour-based products in tropical and subtropical region. Smith) was evaluated for pesticidal and pest repellency activities against T. castaneum, using surface film method and filter paper disc method, respectively. Activity of the isolated compound 3,4-dihydroxybenzoic acid was evaluated against the pest. Pests/insects often cause extensive damage to stored grain products, which is a serious problem throughout the world [1]. In many areas of the world, locally available materials are used to protect stored products against damage caused by pest infestation. Pesticides of plant origin, because of their high degree of tolerance by the mammals, are desired for application against pests of fodders, fruits, vegetables and stored grains [2,3]. The using of plant extracts in pest control has been practiced for at least two millennia, when botanical
