Abstract

The potential of using plant and plant-derived products as deterrent against pest of crops in the field and during postharvest period, is gaining increasing attention, due to rapid development of resistance to the synthetic insecticides and couple with the fact that natural insecticides constitute a rich source of bioactive compounds that are safe and biodegradable into non-Toxic products. The aim of the present study was to evaluate the insecticidal effects of chloroform extract of Pandanus amaryllifolius L. leaves against diamondback moth, Plutella xylostella under laboratory conditions. The medicinal plants were collected around Kampong Sungai Siput, Lubok China, Malacca, Malaysia. The leaf disc immersion method was used to assess the insecticidal effects of Pandanus amaryllifolius L. leaves extract on the larvae as well as duration of the larval phase following feeding of the second instar larvae of diamondback on the treated leaf discs for 24?h at various concentrations (0.5, 1, 2, 4 and 8?mg/ml). Larval mortality was evaluated every 24 hours for a period of three days. Highest larval percent was observed at 72hrs post exposure with 86.67 % mortality at 8mg/ml concentration LC50 and LC90 value was calculated against different concentrations. It was recorded that lowest LC50 and LC90 values were observed after 72?h of exposure followed by 48?h at 2.84?mg/ml and 17.59?mg/ml respectively and 3.36?mg/ml and 28.59?mg/ml respectively at 48?h of exposure time. Both larvae mortality and duration of exposure were found to be directly related to the concentration of Pandan amaryllifolius L. leaves extract and inversely related to fecundity. The present study indicates that phytochemicals derived from Pandanus amaryllifolius L. leaf extracts are effective DBM control agent and the plant extracts may be useful for further IPM program.
