据马来西亚1976年国际农业、油棕会议文集报道,沙捞越有2000多公顷的油棕遭刺蛾为害。当地研究机构对刺蛾幼虫进行了病毒接种研究,发现幼虫在接种后第四天死亡率达77.3%。虫龄五天以上的幼虫容易感病。用鼓风弥雾机喷洒接种体,8天内刺蛾幼虫死亡率高达85.7—98.6%,而未喷洒的对照区仅0.8%。降雨量与死亡率呈正相关。就喷射接种体的扩散面来看,用鼓风弥雾机比用背负式喷雾器效果好。用这种方法防治虫害的费用,只等于化学防治法的40%。
According to the proceedings of the International Conference on Agriculture and Oil Palm in Malaysia in 1976, more than 2,000 hectares of oil palm salamander in Sarawak were harmed. The local research institute conducted a virus inoculation study on the larvae of the thorn moth and found that the mortality of the larvae on the fourth day after inoculation reached 77.3%. Larvae more than five days old susceptible to disease. Inoculation of the inoculum with a blower fogger lasted up to 85.7-98.6% in 8 days compared with only 0.8% in the un-sprayed control. There is a positive correlation between rainfall and mortality. In view of the diffusion surface of the spray inoculum, it is better to use the blower fogger than the knapsack sprayer. The cost of pest control in this way is only equal to 40% of the chemical control law.
