Chilli is a valuable vegetable crop, and its spiciness is due to an alkaloid called capsaicin, which also has notable medicinal benefits. The chilli crop is severely affected by the yellow mite (Polyphagotarsonemus latus), which can lead to significant yield losses. To better understand its behavior, a study on the population dynamics of this pest was conducted during 2023 and 2024 at SKNAU, Jobner. The infestation of yellow mites commenced in the last week of August (35th SMW) in 2023 and 2024 and remained throughout the crop season during both the years. Initially, the mean population was 0.88 and 1.48 mites per three leaves during 2023 and 2024, respectively, which gradually increased and touched its peak with mean population of 21.32 mites per three leaves in second week of October (41th week) during 2023 while, 22.40 mites per three leaves in same duration in 2024. After reaching the peak, the population of mite started to decline during both the years. Occurrence of chilli mite is positively correlated with maximum temperature (r = 0.697 and r = 0.822) during 2023 and 2024, respectively

Yellow mite were found to be major insect pests of chilli and their presence was moderate to high during the experimental period. The peak population of chilli mite was recorded in the second week of October during Kharif, 2023 and 2024. Simple correlation studies revealed that there was significant effect of maximum temperature on incidence of chilli mite. Hence the population is in dynamics during the entire period and the appropriate IPM practices can be followed during the peak incidence of pest
