Abstract:

In order to clarify the relationship between the occurrence of macrosiphum avenae and meteorological factors, this study conducted a systematic survey of aphid populations in wheat fields in Jin'an District, Lu'an City from November 2020 to May 2023. Through correlation analysis, it is concluded that: the peak occurrence period of macrosiphum avenae in the field is during the wheat seedling stage, heading and flowering stage, and grain filling stage; the key factors affecting the occurrence of macrosiphum avenae are mainly positively correlated with daily average temperature X1 (P<0.01), average maximum temperature X2 (P<0.01), daily average minimum temperature X3 (P<0.01), and daily average minimum soil temperature X8 (P<0.01); the meteorological factors of daily average wind speed X6 and daily average rainfall X7 have a negative correlation with the occurrence of wheat aphids, but the infulence of radiation and ralative humidity are not significant. The results provide scientific parameters and theoretical basis for the decision-making of Sitobion avenae control in this region.
