摘要
应用四臂嗅觉仪室内测定5种引诱物对红棕象甲成虫的嗅觉反应。结果表明,5种试验材料对试虫有一定引诱作用,其中聚集信息素、活雌虫和甘蔗诱集效果最明显。田问诱集试验结果表明,聚集信息素、活雌虫和甘蔗对红棕象甲成虫有好的大田诱集作用,菠萝和假槟榔田间诱集效果不明显。种群动态监测结果表明,红棕象甲在海南文昌地区,1 a有4次发生高峰期。
The olfactory response of red palm weevil to five attractants was tested with four-armed olfactometer. The results suggested that all the five attractants showed attractive efficacy to some extent, among which the aggregation pheromone, the female weevils and sugarcane showed strong attractive effect. The field test showed that the aggregation pheromone, female weevils and sugarcane had good attractive effect. Pineapple and Archontophoenix alexanrae had no effect in the field. The result of the population monitoring of red palm weevil showed that the red palm weevil occurred in four peaks a year in the area of Wenchang, Hainan Province.
