Repellent Effect of The Pandanus (Pandanus amaryllifolius R oxb.) and Neem (Azadirachta indica) Against Rice Weevil Sitophilus oryzae L (Coleoptera, Curculionidae)

Sigit Prastowo , Slamet Fauzi

The aim of this study was to determine the effect of Pandanus (Pandanus amaryllifolius Roxb.) and Neem (Azadirachta indica) leaves powder on the repellency, mortality, and weight loss of grains due to Sitophilus oryzae. The methodes of this study used a completely randomized design with 7 treatments and 4 replications. The results of this study showed the best treatment in terms of causing repellency was the treatment of 10 grams of pandanus with a percentage of 87.5%, while the best treatment in terms of causing pest mortality and was also able to reduce the risk of rice weight loss due to Sitophilus oryzae was treatment 10 gram of neem with a mortality percentage of 76.25% and weight loss of rice 3.14%. This research showed that neem leaf compounds are better in terms of causing mortality, while Pandanus compounds are better in terms of causing mortality of Sitophilus oryzae. The repellency effect is due to the volatile compounds produced by insecticides so that insects stay away from bioinsecticide sources. The mortality of insects due to volatile compounds that evaporate can interfere with the physiological function of insects through the entry of spiracles so that they interfere with breathing and cause death. The results of this research still need to be continued by other researchers by separating pure compounds from pandanus and neem leaves and formulating them in gas form (nanopesticides) so that it will become new products in the form of biodegradable fumigants.
