Aplication of an attractive pheromone of bees in watermelon (Citrullus lanatus), in Rosales Chihuahua

Abstract

The present exploratory and descriptive research was carried out in an agricultural land in Rosales, Chihuahua, in the culture of watermelon. An attractant pheromone, due to its smell, from bees was used for the pollination process of the crop. The plant is monoecious; for this condition, entomophilic pollination is important to fertilize the flower. 1.5 kg was applied. of the Nasanov pheromone to one hectare of cultivation and in another part of the farm the control hectare was located. Fourteen hives strategically located in the treated hectare were used. The application date was May 4, 2020, at the beginning of flowering. The first cut was on May 29, 2020 where a difference of 0.63 kg was observed. more weight in treated watermelons; the second cut there was also an increase of 5.33 kg, in the third cut 1,334 kg was manifested in the treated ones and in the fourth cut the difference per unit was 0.53 kg. in those treated. The plants treated with pheromone showed pollination processes in time, so the fruits had a greater weight, as reflected in the four cuts, especially in the second. Student's t tests were performed using the R Studio package, which had a significance lower than 0.05, so it is concluded that the average increase in the weight of treated watermelon was higher than the control. The economic and financial evaluation was feasible, according to the indicators: NPV=37272.33, IRR=42% and Cost benefit ratio= 1.31.
