Bioefficacy of Atalantia Monophylla (L.) Correa. Against Earias Vittella Fab.

Abstract

Hexane, chloroform and ethyl acetate extracts of the leaves of Atalantia monophylla (L.) Correa. were evaluated for their antifeedant and larvicidal activities along with their effect on pupation and adult emergence against bhendi fruit borer, Earias vittella Fab. at 5, 2.5 and 1.25% concentrations. Commercial botanical insecticide, Vijay Neem was used as positive control. Hexane extract at 5% concentration showed significant antifeedant and larvicidal activity of 70.89 and 85.33% respectively. A reduction of 16.66% in adult emergence was recorded in hexane extract followed by 25% reduction in ethyl acetate extract at 5% concentration. The results revealed that hexane extract showed significant antifeedant, and larvicidal activity and good reduction in adult emergence. This extract could be further investigated to isolate the active principles.

Evaluation of fractions and 5,7-dihydroxy-4',6-dimethoxy-flavone fromClerodendrum phlomidis Linn. F. against Helicoverpa armigera Hub.

“…This agreed with the earlier observation of Muthu et al (2010) who reported very low adult emergence was observed in hexane and ethyl acetate extracts of Atalantia monophylla against E. vittella; Baskar et al (2009) observed complete prevention of adult emergence of H. armigera at higher concentration. Further, the fractions from the chloroform extract of Caesalpinia bonduc reduced the emergence of S. litura .…”

Bio Efficacy of Atalantia monophylla (L) Correa (Rutaceae) against Spodoptera litura Fabricius (Lepidoptera: Noctuidae)

“…maximum larvicidal activity against S. litura. The present findings coincide with the findings of Muthu et al [15] who noticed that hexane extract of A. monophylla showed 85.33% larvicidal activity at 5.0% concentration against E. vittella. Extracts from Sonchus oleraceus (Asteraceae), Raphanus sativus L. and Brassica nigra L. (Brassicaceae) exhibited larvicidal activity against S. littoralis [22].…”

“…Present findings coincide with the findings of Baskar et al [14] who reported that hexane extract kill 100% pupae of H. armigera at 5.0% concentration. Muthu et al [15] reported that hexane extract of A. monophylla reduced the adult emergence of E. vittella in a dose dependent manner. Leaves of Ayapana triplinervis (Vahl) R. M. King & H. Rob (Syn.…”

“…Roots are used for antispasmodic [13]. Many insecticidal properties like antifeedant, larvicidal, growth inhibitory, reduced the adult emergence against H. armigera and E. vittella [14,15] were reported.…”

Antifeedant activity of a novel 6-(4,7-hydroxy-heptyl) quinone® from the leaves of the milkweed Pergularia daemia on the cotton bollworm Helicoverpa armigera (Hub.) and the tobacco armyworm Spodoptera litura (Fab.)

“…They observed that ethyl acetate extract showed 100% mortality against Anopheles subpictus and Culex tritaeniorhynchus at 1000 ppm concentration and 76% and 71% mortality against Haemaphysalis bispinosa and Paramphistomum cervi, respectively, at 2500 ppm concentrations. Earlier, Muthu et al (2010) reported that ethyl extract of Atalantia monophylla exhibited 78.67% antifeedant activity against Earias vittella.…”
