甘蔗是福建省沿海农区的主要经济作物之一.常年种植面积为60多万亩;近年来,我省甘蔗种植面积有所发展,1984年已扩种到80多万亩.蛴螬是当地蔗园普遍发生、为害严重的地下害虫,尤以丘陵旱地的蔗园受害损失最大.蛴螬食害蔗苗和分蘖茎的根、根带及基部,致使幼蔗生长衰弱或枯死;蛴螬常把蔗茎地下部的葫芦头啃成洞穴,致使蔗株的长势弱、倒伏或枯死.蔗园的蛴螬种类很多,各地发生为害的优势种类也不尽相同,亟需查明.为此笔者对闽南各县的蔗园进行抽样挖查,以期查明闽南蔗园发生为害的蛴螬的优势种类及其密度,进而提出切合实际的防治措施.
Sugarcane is one of the major cash crops in the coastal agricultural areas of Fujian Province, with a perennial planting area of more than 600,000 mu. In recent years, sugarcane acreage has been developed in our province and expanded to more than 800,000 mu in 1984. The mound is a local sugarcane Common occurrence of the park, serious damage to underground pests, especially in the hilly drylands of sugar cane damage to the largest loss .Fuss plantlets and tiller tillers stems root, root zone and the base, resulting in weak growth or death of sugarcane; 蛴 螬 often cane stems underground Department of gourd head bite into a cave, resulting in the growth of cane strains weak, lodging or dead.Carcophagi many types of calamity, the occurrence of damage around the different types of advantages, it is urgent need to identify.To this end, the counties in southern Fujian Sugarcane garden sampling and digging, in order to identify the occurrence of southern Fujian cane harm the dominant species and density, and then put forward practical control measures.
