Research on sampling methods for insect diversity monitoring
In order to compare the differences in insect communities collected by Malaise trap and pitfall trap method,this study was conducted in Cangshan Tea Garden in Dali,Yunnan Province,from November 11th to 18th,2023.Insects were collected by Malaise trap and pitfall trap with a collection period of 2 hours per cycle,and collected for 6 days.A total of 2,990 insects belonging to 10 orders and 48 families were collected by the two methods,among which 887 insects belonging to 10 orders and 40 families were collected by Malaise traps,and 2,103 insects belonging to 8 orders and 24 families were collected by pitfall traps.There were significant differences in the insect communities collected by the two methods,with the most significant differences observed in the families Acrididae,Drosophilidae,and Formicidae collected by pitfall traps,and the families Cicadellidae and Coccinellidae collected by Malaise traps.There was a significant difference between 12 and 20 o'clock.The dominant families were also different,with Malaise traps collecting dominant families such as Culicidae(38.78%)and Cicadellidae(10.82%),which are insects capable of flight,while pitfall traps collected dominant families such as Formicidae(87.40%)and other crawling insects.Considering the differences in insect communities collected due to the different principles of collection methods,insect diversity monitoring should be conducted by using various methods such as Malaise traps and pitfall traps.
