Abstract

Brinjal (Solanum melongena L.), also known as eggplant, is an economically and nutritionally significant vegetable crop cultivated worldwide, particularly in tropical and subtropical regions is vulnerable to a range of insect pests at various stages of growth. These pests can lead to direct damage through feeding and indirect damage by transmitting diseases. The whitefly (Bemisia tabaci) is a major pest of brinjal, affecting its growth and yield through direct feeding and as a vector for various plant viruses. Mostly farmer of Sindh depending upon highly hazards insecticides on vegetables. Therefore, research was conducted at the field of Plant Protection Research Institute Tandojam during 2024-25 to determine the influence different coloured sticky traps to attraction of whitefly and the role of abiotic factor such as temperature with range (23 to 38 °C) however the relative humidity % range was observed (56 to 84%) and also checked the wind speed range (7 to 13).  Five coloured sticky traps i.e., yellow; blue, green, red, and transparent were used in the study. Observations were taken from sticky traps in weekly basis. The experiment was arranged in RCBD design with three replications. The result showed that the highest whitefly attraction (24.33±2.18 whitefly per trap) was recorded on yellow coloured sticky traps followed by blue coloured sticky (14±1.15 whitefly per trap), while lowest (9±0.57 whitefly per trap) attraction of whitefly was found on transparent coloured sticky traps, followed by red coloured sticky (10.33±0.33 whitefly per trap) and green (12±0.57 whitefly per trap) respectively. Over all means were show the significant the yellow sticky trap was highest attraction of whitefly (19.64±1.20) and the lowest attraction of whitefly in transparent (7.16±0.35) followed by blue, green,  and red (14±1.15, 12±0.57, and 10.33±0.33). It has been observed that population of whitefly found strong, positive and highly significant relation among the respective coloured sticky traps with abiotic factors. Therefore, it is suggested that yellow sticky traps should be considered for better monitoring and integrated management of whitefly.
