The Occurrence and Control Situation and Standardized Management of Lithocolletis ringoniella in Apple Orchards in the Loess Plateau of China
摘要
Abstract
Investigation on the occurrence degree,control measures of Lithocolletis ringoniella and production level of fruit industry was made in three counties in the Loess Plateau region,and standardized management measures were proposed.The results showed that the occurrence degree of Lithocolletis ringoniella in this area was serious,both the rates of damaged orchard and plant were 100％ in August,the average rate of damaged leaf was 39.7％,and the number of spots per hundred leaves was 95.2.Regular and high-frequent chemical control was given excessive emphases in the process of pest control,and the rate of fruit growers who took control measures according to the occurrence of orchard pests was only 9.1％.In addition,there were many other problems contributing to the outbreak of this insect pest,such as serious aging of apple trees,high planting density and large number of orchards cultivated in clear tillage.The main reasons of the occurrence of this insect pest in local district were the weak effect of the orchard ecosystem in controlling pests,which was caused by the weakness of the apple tree and the weak control effect of the natural enemy towards pests,and the improper pest control measures.Then,the standardized management measures were proposed,including three parts,namely enhancing tree vigor,enhancing the control effect of natural enemies and standardizing control methods,and five measures,namely thinning,flower and fruit thinning,interplanting grass,soil improvement,standardized prevention and control measures.Under the combined action of these measures,the continuous control of Lithocolletis ringoniella could be achieved,and this model can be extended to other pest management practices.关键词
