Abstract

The tomato (Solanum lycopersicum L., Solanaceae) is a crop has suffered from insect attacks and environmental factors. The objective of this work was to evaluate the correlations of climatic factors and two key pests at the development of cultivars. The study was conducted in Alagoas, Northeastern Brazil, monitored from September 2016 to August 2017. The experimental randomized with five treatments and twelve replicates. Collection of adult insects was performed with Delta® traps with Tuta absoluta pheromone and Bemisia tabaci Genn. through manual harvesting. Data were analyzed by Pearson correlation and climatic factors. Data were subjected to analysis of variance, and the means were compared by the Tukey test at the 5%. probability. In numbers of flower buds, the cultivars Santa Cruz and Rio Grande gave the highest values, 9.65 and 13.6, respectively. In numbers of fruits, the cultivar Cereja gave higher yields, with a mean value of 6.91. For fruit diameter, the cultivars Santa Clara, Caline IPA 6 and Santa Cruz produced fruits whose diameter was 2.93 cm, 2.95 cm and 3.22 cm, respectively. In of fruit weight, the cultivars Caline IPA 6 and Santa Cruz gave averages of 29.14 g and 38.9 g, respectively, both superior to those of the other cultivars studied. The correlations precipitation, radiation, temperature and wind were climatic factors contributing to the development of tomato varieties in protected crops and caused damage to the physiology of the plant, and acted as environmental indicators for the planning of integrated pest management.
