Cassia Renigera

Petroleum (Pet.) ether, CHCl3 and CH3OH extracts of Cassia renigera Benth. were tested against Callosobruchus chinensis L. for dose-mortality and repellency; and against Sitophilus oryzae L. and Tribolium castaneum (Hbst.) for repellent activity test. The Pet. ether extract of leaf was found active against C. chinensis adults through dose mortality assay and the LD50 values established were 9.270, 4.932, 2.032, 1.721, 1.671, 1.543, 1.513, 1.503 and 1.478 mg cm-2 for 0.5, 6, 12, 18, 24, 30, 36, 42 and 48 h of exposure respectively. However, the leaf extracts of CHCl3 and CH3OH; as well as the Pet. ether, CHCl3 and CH3OH extracts of the stem-bark did not give mortality to the test organism. The CHCl3 extract of leaf showed repellent activity against Tribolium castaneum at 0.1% level of significance (P < 0.001), and the Pet. ether extracts of the leaf and the CH3OH extracts of the stem-bark offered repellency at 1% level of significance (P < 0.01) between dose levels. Only the CHCl3 extracts of the stem-bark gave repellency at 5% level of significance (P < 0.05), while the CH3OH extracts of leaf and Pet. ether extract of stem-bark did not show any significant repellency at all.

Repellent activity of different solvent extracts of Zingiber cassumunar rhizome and leaf against Tribolium castaneum and T. confusum were conducted. The results indicated that both the insect species were repelled by Z. cassumunar rhizome and leaf extracts. Among these, acetone extracts of rhizome showed highest repellency to T. castaneum than those of other extract tested. Petroleum ether extracts of Z. cassumunar leaf acted as repulsive to T. castaneum whereas other extracts exhibited weak to moderate effects to the beetles. All the extracts of leaf produced weak to moderate effects to T. confusum however, methanol extract of leaf showed little effect to the bettles.

Laboratory experiments were carried out to investigate the efficacy of sugarcane bagasse-based lignin against four stored grain insect pests viz., Tribolium castaneum, Tribolium confusum, Sitophilus oryzae and Callosobruchus maculatus. Mortality was assessed after 24, 48 and 72 h of treatment and LD50 values were calculated at the respective time intervals. It was observed that T. castaneum is more susceptible to the lignin than the other test insects. Repellent activity of the product was conducted for T. castaneum and T. confusum. All the concentrations of the product were found to be repellent to both the insect species. Strong repellent activity was observed at concentrations of 471.57 and 628.76 µg.cm-2 to T. confusum showing the repellency of class V activity.

Summary The purpose of this study is to assess the repellent activity of lemongrass (Cymbopogon citratus) essential oil (EO), grown in Serbia under greenhouse conditions, against four prevalent stored product pests: Plodia interpunctella (larvae), Sitophilus oryzae, Acanthoscelides obtectus and Tribolium castaneum (adults). The lemongrass EO repellency was tested using filter paper in Petri dishes and a Y-tube olfactometer. According to the repellency index (RI), the lemongrass EO repellency was divided into 5 classes. Prior to biotesting, the chemical characterization of lemongrass EO was performed and the following main compounds were detected: myrcene (31.0%), geranial (30.0%), and neral (23.6%). The C. citratus EO considered was found to exhibit the Class III repellent activity against P. interpunctella larvae only at the highest concentration (namely 0.5%). This is the very first report on the C. citratus EO repellent activity against this pest. The lemongrass EO examined showed strong repellency (Class IV) against S. oryzae (0.2% and 0.5% of EO), A. obtectus (0.1% and 0.2%), and T. castaneum (0.05-0.1%). Moreover, higher lemongrass EO concentrations (0.5%) were found to exhibit extreme repellency (Class V) against A. obtectus and T. castaneum. The results obtained were confirmed in the bioassays performed, indicating the great potential of lemongrass EO as a bio-repellent when applied in higher concentrations to all the insects considered, regardless of the exposure period.

Context: Repellency test can play an important role in special environmental conditions. Objectives: The main objective of this study was to make a standard protocol to control the pest by screening the test materials using adult beetles by repellency test to see whether or not the extracts contain any potential to repel the stored grain pest. Materials and Methods: The experiment was conducted in choice chamber, which was divided by half filter paper discs (Whatman No. 40, diameter 9 cm). One half of the filter paper was loaded with untreated (control) and the other half was loaded with the extract of A. augusta. All the CHCl3 extracts were separately applied onto each of the half-discs and allowed to dry out in the air for 10 mins. Each treated half-disc was then attached lengthwise, edge-to-edge, to a control half-disc with adhesive tape and placed in petri dishes. The orientation of the same was changed in the replicates to avoid the effects of any external directional stimulus affecting the distribution of the test insects Tribolium castaneum (Herbst). Ten adult insects were released in the middle of each of the filter-paper circles and each test was replicated five times. Results: All the test extracts of seed, leaves, root wood, stem bark and stem wood of A. augusta collected in chloroform showed repellent activity against adult beetles of T. castaneum at dose levels of 314.540, 157.270, 78.635, 39.318, 19.659 and, 9.831 ?g/cm2 on filter paper. According to the intensity of repellency the results could be arranged in the order: stem bark >seed> root wood > leaf > stem wood and in all the cases significant differences were obtained. Conclusion: The present results revealed that A. augusta extracts can be used as a reduced risk repellent compound in the grain and cereal stores to manage the population of T. castaneum. The results also seen to be encouraging when there is a greater need for environment-friendly pesticides then ever before. DOI: http://dx.doi.org/10.3329/jbs.v20i0.17655 J. bio-sci. 20: 49-55, 2012
