斜纹夜蛾是一种杂食性的害虫,是福建沿海旱作地区为害花生、甘薯等作物的主要害虫之一。曾于一九五○年在晋江、南安一带猖獗发生为害。常年在局部地区发生为害,以往对此虫发生期的测报技术,主要靠测虫灯来观测,由于测虫灯的设置费用大且多受能源的限制,难以开展多点观测及时准确地指导大面积防治。为解决此问题,作者从一九七八年着手研究利用斜纹夜蛾的性引诱在测报上的应用技术。现把三年来的研究结果整理初报于下:
Spodoptera litura is a omnivorous pest and is one of the major pests in perennial crops such as peanut and sweet potato in Fujian coastal dry farming areas. In 1950, it was rampant in Jinjiang and Nanan areas. Perennial pests occurred in some areas. In the past, the measurement and reporting technologies for the occurrence of pests were mainly observed by means of insect pest lamps. Due to the large installation cost of pest-killing lamps and their limited energy resources, it is difficult to carry out multi-point observations to guide large and timely Prevention and treatment of area In order to solve this problem, the author started from 1978 to study the application of the technique of using the lure of Spodoptera litura on the reportage. The results of the three years are now finishing the first report on the next:
