Abstract

Tomato (Lycopersicon esculentum Mill.) is been attacked by a lot of harmful insects. One of the most important are the cotton bollworm (Helicoverpa armigera Hubner), the western flower thrips (Frankliniella occidentalis Pergande), the onion thrips (Thrips tabaci Lindeman), the greenhouse whitefly (Trialeurodes vaporariorum Westwood), the leaf
aphids (Aphis sp.), the two-spotted spider mite (Tetranychus urticae Koch.) and the tomato russet mite (Aculops lycopersici Tryon).
In the past few years, T. absoluta Meyrick (Lepidoptera:
Gelechiidae) is considered as one of the greatest pests of tomato in Republic of Macedonia. Its larvae are the most harmful stage causing major damages, manifested through the presence of irregular mines on tomato leaves. Damage can reach up to 100%. The severe attack on the tomato fruits, reduces the commercial value from 50 to 100% (EPPO,
2005).
During the two years research (2015-2016) the presence of this economically significant pest on tomato in a protected area in two systems of cultivation, conventional and integral system, is determined. Pheromones traps, as a secure method for monitoring and detecting the
presence of T. absoluta, were used for collecting insects. The presence of T. absoluta was proved by morphological analysis of the male genitalia. The main objective of our research was to determine the
correlation between the population dynamics of T. absoluta and climate factors in two production systems – integral and conventional, over two season spring/autumn, at tomatoes in a protected area. The correlation is displayed through statistical analysis of the results, by applying a
software package for statistical processing of the results, SPSS 19.
