栗实象鼻虫(Curculio davidi Faust)是危害板栗最严重的害虫。我们在河南板栗产区调查,每年约有20—40%的栗实被害,严重地区可达90%以上。被害栗实失去食用价值或发芽能力,并易引起发霉腐烂,不便贮运。为了探讨栗实象鼻虫的生物学特性、发生规律及其防治方法,我们于1961至1963年进行了一系列的调查研究,现将研究结果报导如下。 Curculio davidi Faust is the most serious insect pest that affects chestnuts. We survey the chestnut producing areas in Henan Province, about 20-40% of the chestnut trees are harmed each year, up to 90% in severe areas. Victims of real loss of food value or sprouting capacity, and can easily cause moldy rot, inconvenience storage and transportation. In order to investigate the biological characteristics, occurrence regularity and control methods of Curimucae, we conducted a series of investigation from 1961 to 1963, and the results are reported as follows.
