Wang Chenzhu's team at the Institute of Zoology, Chinese Academy of Sciences, systematically elaborated the olfactory sensing mechanism of oriental armyworms on sex pheromones and sweet and sour liquor, which provided an important basis for field monitoring and control of oriental armyworms...
Oriental armyworm, also known as marching insect and shaving insect, is one of the major crop diseases and insects in China, mainly harming wheat, rice, corn, millet, sorghum, millet and other cereal crops. Because of its seasonal migration habits, farmers call it a "god worm" that "comes and goes without a trace, and haunts the ghost".
Using the olfactory response characteristics of insects, accurate monitoring of pest population dynamics is the premise of effective control of oriental armyworms. Sex pheromones have a strong attraction effect on the male moth of oriental armyworm, and sweet and sour liquor also has a good luring effect on oriental armyworm, which can be used as a lure agent to effectively monitor the population occurrence and number of oriental armyworm in the field.
These results show that the oriental armyworm that occurs in North China and the oriental armyworm that occurs in Japan may not be a species; the core containing a single Z11-16:Ald can be used for field monitoring and control of oriental armyworm, which can greatly save costs but does not affect the effect of insect attraction, at the same time, it should also be noted that it cannot be combined with sexual attractants containing Z9-14:Ald, and should also be used separately with sexual attractants with cotton bollworm.
The above research has been funded by the National Natural Science Foundation of China and the Chinese Academy of Sciences.
