The bioefficacy of the aggregation pheromone in mass trapping of rhinoceros beetles (Oryctes rhinoceros L.) in Malaysia. - (:unkn) unknown (My University)
In a field experiment in an oil palm plantation in Malaysia in 1994-96, 0.5-5 traps/ha of aggregation pheromone (ethyl 4-methyloctanoate) were used for trapping Oryctes rhinoceros. The total number of beetles trapped was highest with 5 traps/ha, while the number of beetles caught per trap was highest with 0.5 trap/ha. Mass trapping was effective in reducing damage at low pest population levels. However, at high pest populations, while the traps were effective in trapping large number of beetles, palms were still damaged.
