Abstract

The cedar leaf moth (CLM), Acleris undulana Walsingham, has recently become an important pest in the cedar forests in southwestern Turkey. Control has focussed on the use of synthetic chemical pesticides, with little research having been conducted on alternative control methods. In this study, four botanical pesticides (two commercial neem products, Neemazal-T/S-A (R) and Greeneem(A (R)) oil, and two hot water plant extracts, Origanum onites L. and Pimpinella anisum L.) were evaluated for their effects against young (first-second) and older (third-fifth) instar larvae of CLM under laboratory and field conditions. The results of larval dip bioassay in the laboratory showed that all the botanical pesticides tested had significant larvicidal activity against both young and older instars of CLM compared to the water-treated control. Of the botanical pesticides tested, Neemazal was the most larvicidal botanical, causing mortalities ranging from 84 to 100%, the least effective was the P. anisum extract, but at high concentrations this extract still caused significant mortality. Results from field trials also revealed that the botanical pesticides had larvicidal activity against CLM. Neemazal was the most larvicidal botanical, followed by Greeneem oil then by O. onites and finally by P. anisum. Our overall results suggest that all the botanical pesticides tested are promising as larvicides against CLM, and may provide an alternative control method that is more compatible with Integrated Pest Management programs than the use of synthetic chemical pesticides.
