Advance on the affect factors of entomopathogenic nematode in control of Cydia pomonella L.
The codling moth,Cydia pomonella L.,is a kind of important pest in the world.It has been recorded in nine provinces(or autonomous regions/municipalities)of China and it seriously threatens the apple or pear production industry in China.Currently,chemical control is the major measure in the con-trol of the codling moth,however,heavy use of chemical pesticides has caused excessive pesticide residues,and influenced the fruit quality and human health.Thus,it will be of great significance to develop new biological control productions.Entomopathogenic nematodes(EPN)have the ability to actively hunt for the insect host,and have the potential application for biological control overwintering larvae of the codling moth.In order to provide a reference for the efficient use EPN to control the codling moth in the field,we review the efficient strains of EPN in control of the codling moth,and the factors(tempera-ture,humidity and ultraviolet light)which affect the control efficiency.
