Abstract

Insect pollinators play an important role in the pollination process of mango (Mangifera indica L.) plants, which directly affects the process of productivity and fruit quality. This study aims to determine the relationship between insect pollinator activity and climatic factors including temperature, humidity, rainfall, and light intensity. This research was conducted in mango plantation of Gadung 21 variety in Oro-Oro Ombo Village, Pasuruan Regency, during the flowering phase of the plant. Insect sampling was conducted using yellow trap and sweep net, while climate data was obtained through NASA POWER. Data were analyzed using Pearson correlation test and linear regression to determine the significant relationship between climatic parameters and insect numbers. Observations showed five main types of pollinator insects: yellow flies (Eristalis tenax), green flies (Lucilia spp.), honey bees (Apis mellifera), klanceng bees (Trigona spp.), and butterflies (Appias lybithea). Results showed that temperature (28-30oC) and humidity (70-85%) were significantly positively correlated to pollinator activity (r > 0.67), while rainfall showed a significant negative correlation (r < -0.5). Light intensity also plays a role in increasing pollination activity especially during morning to afternoon hours. It can be concluded that the dynamics of insect pollinator presence is significantly influenced by microclimatic conditions, so the management of mango cultivation needs to consider these factors to increase the efficiency of natural pollination.
