Study On Key Techniques For Controlling Fruit-borer In Apple Orchard In Shihezi Reclamation Area

In this study,we use sex attractants,mating disruption techniques,fruit bagging and insect trapping belt techniques to study the dynamics of species and population dynamics of fruit borer in single-plant apple orchards in Shihezi reclamation area,compare the monitoring effects of different types of sex attractants,integrate and recommend apple orchards Key technology for the control of fruit borer.The research content is as follows: 1 The apple orchard hangs obligate fruit borer sex attractants to monitor the types of the fruit borer in apple orchardsFrom April to October 2019,regular field surveys of apple orchards fruit borer in apple orchards were conducted.The dominant population of apple orchards fruit borer in apple orchards in Shihezi reclamation area was Grapholita molesta Busck,which accounted for 76.22% of the total number of moths,followed by Cydia pomonella L.of fruit borer(23.78%).In apple orchards in Shihezi reclamation area,Grapholita molesta Busck occurs four times a year,and Cydia pomonella L.occur five times a year.Both types of fruit borer overlap in the apple orchard.2 Hanging the mating disruption silks in the apple orchard to study the control effect of the mating disruption technology on the apple orchardIn the apple orchard,the single-mating disruption technology and the mating disruption technology and its combined chemical control are used to evaluate the control effect through the insect fruit rate and the mating disruption rate;The mating disruption technology used in successive years(2018-2019)has better control effect(the mating disruption rate of Grapholita molesta Busck in 2019 increased by 36.67% compared with that in 2018),The combination of mating disruption technology and pesticides in controlling apple orchard fruit borer in apple orchards(the mating disruption rate of Grapholita molesta Busck is 99.41%)was higher than that of the use of the single-mating disruption technology(the mating disruption rate of Grapholita molesta Busck is 43.33%).Studies have shown that in production practice,the mating disruption technology should be used year after year,combined with chemical control,the control effect is more significant;Selecting different companies' mating disruption silks,The control effect of mating disruption silks produced by Zhongjie Sifang Biotechnology Co.,Ltd.is higher than that of the use of mating disruption silks from the Institute of Zoology of the Chinese Academy of Sciences against fruit borer in apple orchards.The mating disruption rate of Grapholita molesta Busck increased by 19.07% year-on-year,and that of Cydia pomonella L.of apples increased by 69.26%.This shows that the selection of Zhongjie Sifang's mating disruption silk has better control effect.3 In the apple orchard,by hanging different sex attractants,fruit bagging and tying insect trapping belt,study the control effects of other control techniques on apple orchard fruit borerIn the apple orchard,sex attractants were used to control the fruit borer.The trapping effects of different color sex attractants were compared.Different color traps were set to monitor the occurrence of the apple orchard fruit borer.Studies have shown that the number of green traps(average daily trapping number is 42.09)is higher than that of white traps(average daily trapping number is 17.89),indicating that green traps have a better effect on trapping fruit borer in apple orchards.The sex attractants lure from different manufacturers were set in apple orchards to monitor the occurrence of fruit borer in apple orchards.Studies have shown that the number of sex attractants trapped in the Institute of Zoology of the Chinese Academy of Sciences(the average number of traps per day is 11.77)is higher than that of Beijing Zhongjie Sifang Biotechnology Co.,Ltd.The number of traps(the average number of traps per day is 10.20)shows that the trap of the Institute of Zoology of the Chinese Academy of Sciences has a better effect on trapping fruit borer in apple orchards.However,the trapping efficiency of Beijing Zhongjie Sifang Biotechnology Co.,Ltd.sex attractants to lure Cydia pomonella L.is relatively higher(the number of trapping Cydia pomonella L.of Beijing Zhongjie Sifang Biotechnology Co.,Ltd.sex attractant lure is higher than that the Institute of Zoology of the Chinese Academy of Sciences).Studies have shown that when sexual attractants are used to control fruit borer in apple orchards,the sex attractants lure of the the Institute of Zoology of the Chinese Academy of Sciences combined with green traps are more effective in trapping fruit borer in orchards and have better monitoring effects.Choose the best bagging time in order to achieve the best control effect.Studies have shown that apple bagging has a better control effect on orchard fruit borer(control effect up to 93.33%),and the earlier the bagging time,the better.Use the insect trapping belt(corrugated paper)to artificially make the overwintering place in the orchard fruit borer,investigate the number of larvae,and study the control effect of the insect trapping belt on the orchard fruit borer.The investigation shows that the orchards of orchards overwinter mainly at the base of fruit tree trunks.Overwintering larvae can be effectively trapped by artificially making corrugated paper overwintering sites,and have good control effects(the maximum number of corrugated paper trapping fruit borer is 5).
