Population Dynamics of Tomato Fruit Borer Helicoverpa armigera

In order to gain a better understanding of the seasonal development and dynamics of tomato fruit borer (Helicoverpa armigera) on tomato in the Zaid season 2022, an experimental study was carried out in the state of Punjab. The population distribution of fruit borer pest is influenced during the growth season of the crop by abiotic conditions, and these factors can have either a favourable or negative effect. As a result of the fact that tomatoes can be cultivated during a variety of seasons, one can see vivid population dynamics in case of fruit borer during the Standard Meteorological Weeks (SMW). In the current experiment, the first occurance of a fruit borer was noticed during the 11^th standard meterological week (the second week of March), and the population reached its highest peak during the 18^th and 19^th SMW (the first week of May). According to the findings of the correlation studies, maximum and minimum temperature have a significant positive relationship in either enhancing or lowering the population of fruit borers.
