Abstract:
The experiment was carried out on Monitoring of the Drosicha mangiferae in different varieties of mango through various colored sticky trap in Tando Jam at Horticulture Garden, Sindh Agriculture University, Tando Jam from November 2018 to March 2019. The orchard comprises four mango varieties such as Chausa, Langra, Sindhri and Sonaro, total five mango trees were selected randomly, one from center and four from different sides (North, South, West, and East) and Three different colors of the sticky traps i.e. Blue, green and yellow were installed. The experiment on the monitoring and influence of color traps on the attractiveness of the population of Drosicha mangiferae in different varieties of mango revealed that black ants, the damselfly, the Brumus beetle, the zigzag beetle, the spiders, the mite, the mango mealy bug and the mango hoppers were attracted the colored traps. Maximum 150 males of Drosicha mangiferae were caught on yellow sticky traps compared with green 50 and blue 15. The appearance of adults on traps was recorded during April and May 2019. However, maximum catches were recorded in April month. The total catches of all three traps indicated that the traps installed on Sindhri variety had maximum catches 110 adult male Drosicha mangiferaein 41, 33 and 28 on Sonaro, Chaunsa and Langra mango varieties, respectively. The adult females of mango mealy bug collected from the branches of mango plant having sticky traps installed showed significant difference in oviposition that only 70% of the females laid eggs, which were collected from the branches that had sticky blue traps. Among them, 10% of females laid > 100 eggs, while the remaining 60% laid <100 eggs. Similarly, 70% of the females laid their eggs that were collected from the sticky green trap branches. Only 30% of the females laid> 100ggs. 40% of the females laid their eggs, which were collected from the branches that had sticky yellow traps. 30% of them laid <100 eggs. It was concluded that females that laid less than 100 or no eggs were considered unmated females; however, less than 100 eggs could be due to the reproduction of parthenogenesis. Since the sticky traps, especially the yellow color, effectively captured the male Drosicha mangiferae that reduced the possibility of mating with the females, consequently, most of the females descended from the tree without mating. Therefore, it reduced egg production in Drosicha mangiferae. While, overall the total 414 insect pests (arthropods) including Drosicha mangiferae on yellow sticky trap followed by 119 and 115 green and blue sticky traps were trapped on Sindhri, Sonaro, Chaunsa and Langra mango variety trees, respectively.
