Proceedings of the Integrated Management of Crops Pests in Taiwan
Insect pest is one of important limitative factor to rice production in Taiwan. This paper reviews the change of rice insect pest status and basing on the ecological characteristics and economic threshold of pests to develop 1PM systems in Taiwan during past 30 years. Basically, it was observed that the infestation of rice insect pest could be successfully suppressed either by reducing the initial population with cultural practices and / or enhancing the biological and physical resistance of the pests to reduce their growth rate after they invaded paddy fields. In the years of 1960 to 1980, the brown planthopper (BPH), Nilaparvata lugens was a most destructive insect pest, the BPH resistant varieties combination with judicious application of selective or shorter effective insecticides at the booting stage of rice was suggested for controlling the rice insect pests after heading stage. Lately, the damage caused by BPH reduced greatly due to lower immigration, while the infestation caused by the rice leaffolder, Cnaphalocrocis medinalis and white backed planthopper, Sogatella fucifera increased remarkably. These two species as well as some other species of insect pests, such as whorl maggot, Hydrellia philippina and rice water weevil, Lissorhoptrus oryzophilus infested severely on rice in early stage of rice sporadically. In this case, the nursery tray treatment was recommended for control of the initial insect pests, and the need of latter application at the booting state of rice was determined by the treated area of the nurserytray treatment and the supporting levels of water and fertilizer management by farmers. It was obviously that an primary developed 1PM system in rice was gradually accepted by farmers and implemented in their paddy fields. Further improvement of 1PM system in rice is needed urgently. However, the developed system should be simple, effective and practicable to farmers, and that only can be achieved through a close cooperation with the rice breeder culturist, pathologist and the technological extension rpecialists in consideration from ecological social economics, and cultural practical aspects. In other words, the developed 1PM system should be tailored to fit Taiwanese conditions and it should be easily to be fused into local rice cultivated system.
