Response of Caryedon serratus (Oliver) (Bruchidae: Coleoptera) towards Various Botanicals and Hosts

Abstract

Studies on repellence effect of few botanicals on Caryedon serratus (Olivier) in stored groundnut were carried out at Department of Entomology, College of Agriculture, Junagadh Agricultural University, Junagadh during the year 2013-2014. The results revealed that out of seven treatments viz. chilli powder, garlic powder, dhatura powder, custard apple leaf powder, ginger powder, black pepper powder and mint leaf powder @ 5 g/ 50 seeds the treatment of black pepper powder (90.35, 88.95, 87.09, 86.75 and 85.46 per cent  repellence at 15 min, 30 min, 1 h, 2 h and 24 h, respectively) was greater and at par with treatment custard apple leaf powder and garlic powder@ 5 g per 50 g seeds of groundnut compared to datura leaf powder and mint leaf powder. Groundnut seed treated with Tamarindus indica (Ambali), Arachis hypogaea (Groundnut), Acacia nilotica (Babul) and Cassia fistula (Garmalo) were found to be preferred for oviposition by Caryedon serratus as compared to Prosopis juliflora (Gandobaval).
