Trapping effect of the combination of sticky card traps and food attractants on Frankliniella occidentalis in vineyards
As one of exotic pests,Frankliniella occidentalis poses a certain threat to agriculture production and ecological security in China with a wide range of hosts and is currently an important pest of grapes.In order to achieve dynamic monitoring and effective prevention and control of F.occidentalis in vineyards,reduce pesti-cide use,ensure the quality and safety of agricultural products,and promote sustainable green development of agriculture,it is particularly important to explore the physical attraction and control technology for F.occiden-talis.The trapping effects of sticky card traps of different colors(white,yellow,blue)alone,attractant(with trap),and the combination of sticky card traps and attractant on F.occidentalis in vineyards were explored from 2022 to 2023 under rain shelter cultivation with F.occidentalis as control object,and the population dy-namics of F.occidentalis were analyzed at the same time.The results showed that the population dynamic trends of F.occidentalis in grapevines with the use of sticky card traps or food attractants alone,as well as the combination of these two methods,were consistent,and the peak occurrence period of F.occidentalis was basi-cally the same from late May to mid-June.The combination of blue boards and food attractants had the best trapping effect on F.occidentalis in vineyards,with significant differences compared to other treatments at the total trapping quantity(in 150 days)of 4,048 and 3,874 heads,and a daily average of 26.99 and 25.83 heads,in 2022 and 2023,respectively.The trapped number of F.occidentalis by yellow board+attractant(with trap),attractant alone,and blue board alone was the second.There was no significant difference between these four treatments,but with significant differences compared to other treatments.The trapped number of F.occi-dentalis by white board alone and yellow board alone were the least,with no significant difference between these two treatments,but significant differences compared to other treatments.In order to realize the monito-ring of population dynamics and efficient green control of F.occidentalis in vineyards,also taking into account of environmental protection,the combination of blue board and attractant can be used before the appearance of F.occidentalis.
