ABSTRACT

Background: Tribolium 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.

Results: Chloroform soluble fraction of ethanol extract of rhizome of D. quercifolia showed significant pesticidal activity at doses 0.88 to 1.77 mg/cm(2) and significant pest repellency activity at doses 0.94 to 0.23 mg/cm(2). 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.

Conclusion: Considering 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.

Repellency records of chloroform fraction per hour interval up to 5 hours. As dose of chloroform fraction of ethanol extract of rhizome of the plant increased, the repellency property (percent repulsion) of the fraction against the pest also increased. With increasing duration of exposure the repellency property varied (mostly increased), however, within 4 h of exposure duration the repellency property became constant.

Fig2: Repellency records of chloroform fraction per hour interval up to 5 hours. As dose of chloroform fraction of ethanol extract of rhizome of the plant increased, the repellency property (percent repulsion) of the fraction against the pest also increased. With increasing duration of exposure the repellency property varied (mostly increased), however, within 4 h of exposure duration the repellency property became constant.

Mentions: In pest repellency study, chloroform fraction showed good repellency property at all tested doses (0.94 to 0.23 mg/cm2) (Table 3, Figure 2). Observations of first hours not significantly differ from the observations of subsequent hours (second, third, fourth and fifth hours). Like pesticidal activity, pest repellency activity also increased with doses. Petroleum ether, ethyl acetate and methanol soluble fractions as well as 3,4-dihydroxybenzoic acid were also subjected to pest repellency test, but no activity was found.Table 3
