An experiment conducted during the year 2010-2011 at experimental cum research farm, School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema Campus, on the influence of sowing dates against pest complex of tomato to observe its effectiveness in escaping the attack of different pest commonly found damaging tomato plants and its fruits. It was observed that late planting of tomato on 19th December har-boured the least aphid population and early planting of tomato on 19th November harboured the least serpentine leaf miner under Nagaland condition. The total mean aphid population on all the dates after planting had exhibited that crops planted on 19th November planting harboured the maximum (3.41 per plant) aphid population while 19th December planting recorded with the least (2.59 per plant) aphid population. The total mean infestation of serpentine leaf miner on all the dates after planting had exhibited that the crops planted on 19th December planting harboured maximum (6.68 mined leaves/plant) infestation while 19th November planting recorded with least (4.90 per plant) mined leaves.
