RUIZ DIAZ, Ángel Alberto et al. Chemical treatment of corn seed for control of trips (Frankliniella occidentalis) Pergande (Thysanoptera:Thripidae). Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.3, pp.565-576. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i3.1215.

The objective of the present investigation was to evaluate the chemical control of trips Frankliniella occidentalis Pergande (Thysanoptera:Thripidae) with the application of four seed products (thiodicarb, acephato, bifenthrin + imidacloprid and thiametoxan + lambda cyalotrina) with two doses; one according to the dosage of the commercial house and the other 50% smaller, in the variety Roque 1. A randomized block design with four repetitions, 10 treatments and two controls, a hybrid (Ares®-Unisem) was used and a white one. The sampling of the density of trips was carried out by means of a manual aspirator and blue traps, the samplings were made from the emergence of the plants and during eight weeks, carrying out two samplings per week. The results show that the treatment with thiamethoxane + lambda cyalotrine presented the lowest density of trips with a value of 1.53 trips per plant, while the absolute control was the one with the highest value with 2.14.
