Relación entre intensidad de daño de Prodiplosis longifila gagné (diptera: cecidomyiidae) y aspectos fisiológicos del cultivo de tomate

The objective of the research was to evaluate the relationship between P. longifila's injury intensity and physiological aspects of tomato cultivation. The experiment was developed during the dry season of 2018, at the ESPAM MFL polytechnic campus located in Calceta, Manabí, Ecuador. The treatments evaluated were: tomato with handling (T1) and unhandled (T2). Each treatment consisted of 10 plots or experimental units of 30 square meters each, where the data record was carried out in the central plants. The main variables recorded were the relative growth rate (TCR), crop growth rate (TCC), net assimilation rate (TAN), chlorophyll content based on SPAD units, total number of healthy, damaged shoots and plant larvaeˉ¹. The results showed significantly higher amounts (p<0.05) of damaged shoots and number of plant larvae 1 in untreated treatment in relation to pest management treatment. Likewise, fewer healthy outbreaks are evident in the untreated treatment of the insect. Similarly, the unmanaged treatment of P. longifila presents lower TCR, TCC, TAN and chlorophilic content based on SPAD units, in contrast to the treatment with bold management, demonstrating the negative effect of the pest on the physiological aspects cultivation. It is concluded that pest management is key to enhancing the physiological behavior of tomato cultivation.
