Mango is an important, exportable fruit crop of Pakistan. Pakistan is occupying 6th position on the basis of mango production in almost 90 mango producing countries of the world. The mango hopper Idioscopusclypealis is a most destructive insect pest of mangoes in Pakistan. This pest may cause the economic loss to the mangoes due to due to its abundance and high population in dense traditionally managed mango orchards. Keeping in view the importance of the pest, a study was designed with an objective to determine comparative efficacy of four different insecticidal spray modules for effective control of mango hopper on cultivar SufaidChaunsa in the research orchards of Mango Research Institute, Multan during 2019-2021. Another objective was to determine the population dynamics of mango hopper and the effect of weather factors on the population of mango hopper. The infestation of the pest was examined by observing nymphs and adults in a single panicle/inflorescence (10-inch long) from each cardinal directions of the selected trees visually counted during the flowering season on weekly basis.  In module 1, Thiamethoxam (Actara 25 WG) was sprayed after the fruit harvest. In module 2, the insecticide Thiamethoxam (Actara 25WG) was sprayed after the fruit harvest, followed by second spray of Clothianidin (Trunk 20SC) only on tree trunks in the month of December. In module 3, first spray of thiamethoxam was done after fruit harvest, second spray of Clothianidin (Trunk 20SC) only on tree trunks in the month of December and a subsequent third spray of Spinetoram (Delegate 25 WG) was done on mango trees before flowering season in the month of January. The population of mango hopper was significantly lowest in module 3 and higher population of hopper was recorded in control.  Population dynamics studies revealed that mango hopper population reached at its peak in 2nd week of April during 2020 and 3rd week of March in 2021. The population of mango hopper was maximum during mango flowering period, while in the later months the population of mango hopper declined. The effect of weather factors on population abundance of mango hopper revealed that significantly positive correlation and regression was observed with relative humidity and wind while negative correlation was observed with increased temperature and rainfall.

Mango, scientifically known as Mangifera indica L., is highly popular in Pakistan and around the globe and is known for its abundant provitamins and other phytochemical elements. Being a climacteric fruit, mangoes ripen quickly after being harvested. Commercial growers typically harvest mangoes when they reach their horticultural maturity to maintain the fruit's quality. Temperature is a crucial environmental factor affecting mangoes' quality, as these tropical fruits do not respond well to storage at low temperatures. Therefore, this study aimed to examine the impact of different storage conditions on the physiological and biochemical qualities of the shelf life of cv. Sufaid Chaunsa mangoes. During the study, the mangoes were stored in cold storage facilities at 8°C, 12°C, and 16°C. The storage containers consisted of plastic baskets covered with paper, and the mangoes were assessed for weight loss, texture properties, chilling injury, titratable acidity, sensory characteristics, total soluble salts, and external appearance every 7 days throughout the storage period till 28 days. The results indicated that storing mangoes at 12°C extended their shelf life by up to 21 days, shows better results. Utilizing the storing conditions set at 12°C effectively reduced suitable water loss, maintained chemical changes and other sensory characteristics. Additionally, storing the mangoes at 12°C was sufficient to prolong their storage life until 21 days. It was observed that the quality of mangoes deteriorated after being stored for 21 days at 16°C.
