Habitat manipulation for insect pest management in irrigated lowland rice ecosystem

Abstract

A field study to determine the effect of planting flowering weeds and vegetable on bunds on the populations of key insect pests and natural enemies, incidence of insect damages and important rice diseases was conducted during 2014 dry and wet seasons at the Future Rice Farm, PhilRice CES. The bunds of the habitat manipulated plots were planted with flowering weeds and vegetables while a common practice plot (without flowering plants planted on the bunds) was also monitored for comparison. Samplings of the pest population predators and parasitoids was done during the vegetative, reproductive and maturity stages of the rice crop using blow voc suction machine, sweep net and by visual counting. Results showed that arthropod population was generally higher in the habitat-manipulated plot than in the common practice plot, indicating the importance of the flowering plants to the arthropods as either refuge or source of food.
