Abstract:
In order to handle the aphid, Macrosiphoniella sanborni, in Chrysanthemum a field experiment was carried out. The yield was also affected by the low aphid population, which was seen in the crops transplanted during the first week of February (1.40 to 25.78 per 15 cm twig), followed by the third week of January (5.18 to 52.45) and the third week of October (5.84 to 48.48). The incidence of aphid remained between 29 and 36 per 15 cm twig throughout the remainder of the transplanting periods (from the first week of November to the first week of January). Temperature, relative humidity, vapour pressure, and vapour pressure deficit all had a major influence on the pest's variation when taking into account its prevalence and the significance of meteorological elements throughout various transplanting times.
