Leafhoppers (Nepholett.ix spp.), whitebacked planthoppers, [Sogatella furcifera (Horvath)]. brown planthoppers [Nilaparvata lugens (Stål)], ripple bugs (Micrvuelia atrolineala Bergoth), a predatory myrid (Cyrtorhinus lividipennis Reuter) and spiders were sampled from flooded rice using a vacuum sampling device (FARMCOP) and a cone sampler (C02NE). The vacuum sampler was a modified automobile vacuum cleaner powered by batteries and the cone sampler required carbon dioxide gas and aluminum cones. The FARMCOP sampler yielded significantly higher mean numbers of most arthropods except spiders. However, the coefficients of variation for the two techniques were approximately equal and the C02NE sampler was less expensive, required fewer materials to construct, was easier to use, and allowed faster sampling.
