abstract
The experiment was conducted to assess the efficacy of insecticides in the laboratory of NIA, Tandojam, during 2017 on mango fruit. Four insecticides (Laser, Trichlorfon, Lambda, and Malathion) were tested and also compared with each other as well as control. On pupal emergence, the impact of insecticides showed results that highest mean population was observed at different doses of Lambda were 34.25, 25.75, 12.25, 11 and 7.25 then of Malathion were 32.75, 23.25, 23.5, 18.75 and 15.75 and of Laser were 21.00, 20.00, 6.00, 6.5 and 3.75. In contrast, the lowest mean population was observed of Truchloron were 14.25, 15, 13.75, 10.5, and 8.25, respectively. On adult emergence, the highest mean population was found of Lambda were 30, 16.75, 7.75, 7 and 5.25, then Malathion was 15.25, 11, 10.5, 8 and 5, and Laser were 9.75, 10.25, 10.25, 9.5 and 5.75 Whereas lowest of Trichlorfon as 8.75, 8.75, 7.5, 6.5 and 4.5 respectively. While the impact on male and female survivorship ratio recorded on Trichlorfon, the male was 4.75, 5.5, 4.0, 3.5, and 2.25 and female was 3.75, 3.5, 3.25, 3.75, and 3. On Laser, the male was 3.75, 7.0, 5.25, 4.0 and 2.5, and female was 4.5, 5.75, 5, 3.75 and 2.5 but on Malathion, the male was 5.0, 6.0, 3.75, 4.5 and 3.5 and female was 4.5, 5.5, 4.5, 3.75 and 3.25. Where also on Lambda, the male was 6.5, 7, 5.25, 5.25, and 4.75 and female was 5.25, 6, 5.25, 4 and 4.25 respectively.
