Rice arthropod population as influenced by integrating two duck batches in rice-duck farming

Abstract

Conventional rice-duck farming has been considered not only as a means to increase the income of the rice farmers but also as a tool in managing the rice insect pests particularly those found at the rice stems which are mostly rice planthoppers. However, the high planthopper population reported were those observed at the later growth stage of the crop, hence, the benefits derived from this system in terms of pest management is up to reproductive stage of the crop only. The effect of stocking high duck density (500-1000 heads/ha) and releasing two batches of ducks (from vegetable to reproductive stage and from reproductive to maturity stage of rice) on the arthropod population and in controlling pests of rice was assessed during 2014 dry and wet seasons at the experimental field of PhilRice Central Experiment Station. Observations of the pest population and damages were made during the different growth stage of the rice crop using sweepnet and visual count methods of sampling. Results showed that the release of two batches of ducks with high stocking density had a positive effect resulting in a tolerable level of pest population that contributed to a higher level.
