abstract
The experiments were conducted on the damage percent and biology of mango leaf miner Acrocercops syngramma (Meyrick) to assess the plant losses and their remaining active period on different mango varieties viz., Chuanca, Fajiri, Sindhri, Siroli and Langra during 2015. The data showed that significantly (P<0.05) highest damage percent of pest was recorded on Chuansa, whereas the lowest on Langra varieties respectively. The leaf miner, single female laid 49-59 on Chuanca, 42-59 on Fajiri, 44-56 on Siroli, 38-52 on langra and 39-51 eggs on Sindhri mango plants with an average 54.8±4.03, 49.2±6.49, 49.6±4.93, 46.0±5.34 and 44.2±4.82 eggs respectively. Whereas the eggs fertility of A. syngramma on Chuanca, Fajiri, Sindhri, Siroli and Langra, 92.065%, 76.378%, 90.541%, 72.016% and 84.341%, and the pest completes its biology were distinct from 19.7-30.43, 19.66-30.96, 21.0-27.63, 20.96-30.93 and 19.43-33.9 days respectively under laboratory conditions.
