Control de mosca blanca (Bemisia tabaci) en el cultivo de sandía (Citrullus lanatus)

This investigation was carried out to determine the damage of the whitefly (Bemisia tabaci) caused in the production of Citrullus lanatus (watermelon), it showed that this insect is a species of plague with great influence in 17 provinces of Ecuador, causing losses of 25 % to 50% at harvest, it was confirmed that there were 23 hosts, 11 of which were the main host. Susceptibility in the following crops: peppers, tomatoes, melons, watermelons, cucumbers, soybeans and beans. The species of "whitefly" registered at the national level are: Aleurotrixus floccosus in the four regions; Bemisia tabaci and B. argentifolii in the Coast and the Galapagos Islands, and Trialeurodes vaporariorum in the Sierra. In the Babahoyo area, watermelon production has been increasing, the production of which is a source of employment for many people, as a goal the historical analysis of the impact of Whitefly Incidence in watermelon crops is presented below, evaluation of the theoretical basis of whitefly damage in watermelon production, the real situation of the problem is diagnosed in the study, the different types of control that occur in the crop are made known, a little about the watermelon plant the shape of the fruit, the plant, its harvest, the recommendations of the case study are disclosed. Farmers who eradicate whitefly use 34 types of chemicals, sold in the form of insecticides, which have a wide range of effects and are extremely toxic. Another way to eliminate "whiteflies" is to use hymenopteran insects as parasites of insects for biological control, such as: Amitus fuscipennis, Amitus sp., Encarsia nigricephala, Encarsia sp., and Eretmocerus sp.
