The experiment conducted during (2016/ 2017 and 2017/ 2018) at Fac. of Agric. Farm, Assiut Univ. on tomato hybrids to survey arthropods, determine reduction of Tuta absoluta by Proclaim^® 5%  (S₀= 0.3 mm) and nano-formulations (S₁= 17.43± 8.20nm and S₂= 9.75± 3.86nm) by (120 gm/ Fadden) after 5^th, 7^th, and 10^th days of post-treatment under some weather factors (WF): [Daily Maximum Temperature (DMax.T), Daily Minimum Temperature (DMin.T), and Daily relative humidity (DRH%)]. Survey presented nine insect species under nine genera, three mites, three predators and one parasitoid. The highest grand means for mines and immature stages in 18^th of Jan., 2017 and 14^th of March, 2018, and lowest in 3^rd of Nov., 2016 and 4^th of Dec., 2017. Meteorological data in 1^st season were significant with mines and no significant with larvae on hybrids. In 2^nd season, mines regulated by DMax.T (0.447) and DRH% (-0.621) for Vera, and DRH% (-0.540) for 010 with no significance between weather factors and larvae on hybrids. S₂ in the 1^st season highly reduced larvae after 10^th days (103 ± 18.40 and 69.14 ± 14.21; for Vera and 010), and the lowest by S₀ for Vera (10.40 ± 2.22) after 7^th days; and 22.40 ± 1.78 for 010 in 5^th days. In 2^nd season, highest reduction by S₂ (78.64 ± 1.27 and 105.00 ± 6.34 for Vera and 010 in 10^th days; and lowest by S₂ in Vera after 7^th days (17.00 ± 0.61); and S₁ for 010 after 5^th days (29.64 ± 0.81).
