Abstract

The present research project was carried out at the INIAP experimental farm in the canton of Píllaro located in the province of Tungurahua, the objective of the present investigation was to evaluate the different alternatives for the control of Bactericera Cockerelli Sulc in the cultivation of Solanum tree tomato. Betaceum Cav. together with two different plant materials with possible resistance to the incidence of the insect, for the fulfillment of the purpose of this investigation, a divided plot design was developed where three plants were selected from which three leaves located in the upper part were taken, middle and lower part of the plant, the count of eggs, nymphs and adults was carried out in order to carry out the monitoring, the count was carried out visually with the help of a magnifying glass, the data was recorded in an Excel spreadsheet, After monitoring the insect, the different control alternatives were applied depending on the date, the treatments were alternative B1 (chemical control) applied every 10 days, alternative B2 (agricultural oil) applied every 5 days, alternative B3 (kaolin) was applied every 10 days and B4 (control) without application. The results were analyzed in the Infostat statistical program, the Tukey test was applied at 5% and the following results were obtained: the alternative B2 (agricultural oil) and B3 (kaolin), are effective for the population decrease of the insect, obtaining the following means: 13.25 and 10.29 in eggs, 5.14 and 5.18 in nymphs and 0.84 and 0.60 in adults of Bactericera cockerelli, respectively; Based on these results, it is considered that the two alternatives were effective; However, he considers that the best control alternative is B2 with agricultural oil since the plant obtains a population reduction and a good development, contrary to what happens with alternative B3 where kaolin reduces the good development of the plant, which which may be due to different factors that should be studied in a better way so that the use of this product is used in the crop
