LABORATORY ASSESSMENT OF THE REPELLENT PROPERTIES OF ETHANOLIC EXTRACTS OF FOUR PLANTS AGAINST Raphidopalpa foveicollis Lucas (COLEOPTERA: CHRYSOMELIDAE) (Pages : 1 - 5)
PANKAJ TANDON and ANITA SIROHIEthanolic extracts of four plants were assessed in a laboratory for repellent properties against the most damaging pest of cucurbits crop Raphidopalpa foveicollis Lucas (Coleoptera: Chrysomelidae). The aim is to further explore the use of natural pesticides in management programmes to control red pumpkin beetle. The investigation was done in the research laboratory of Department of Zoology, D.A?V Degree College, Kanpur, India during June to September 2008. Laboratory reared adults were exposed to 5% and 10% concentrations of the extracts of Azadirachta indica, Annona squamosa, Convolvulus microphyllus and Melia azedarach respectively in laboratory bioassays. Repellency assays were conducted using the area preference method on filter papers. Result showed that plant Azadirachta indica elicited repellency of class IV (60.1?80%), Anona squamosa and Melia azedarach elicited class III (40.1?60%) and Convolvulus microphyllus elicited repellency of class II (20.1?40%). All of these plant extracts were found significantly effective in repelling red pumpkin beetles. Results indicated attractive potentials for field trails. Download
