DIVERSITY OF THRIPS FAUNA (INSECTA: THYSANOPTERA) IN PLUM ORCHARD FROM MORĂREŞTI-ARGES
Journal Title: Current Trends in Natural Sciences - Year 2012, Vol 1, Issue 2
Abstract
The present study, conducted in the plums orchard of Morăreşti-Argeş at two plum varieties, has revealed a poor biodiversity. All of 10 species of thrips are polyphagous and belong to different trophic links: 8 species of phytophagous and 2 species, Aeolothrips intermedius and Haplothrips kurdjumovi are zoophagous. The structural parameters values indicate Haplothrips minutus as plum characteristic species, with the highest values of relative abundance and frequency in samples. However, this species has insignificant damaging in plum orchards. The low values of the structural indicators of the other species express their attachment to their characteristic trophic substratum, i.e. the herbaceous layer, so they only accidentally get on the plum branches, through anemochory. The Shannon-Weaver diversity index and equitability have low values, a situation which is typical of agro-ecosystems.
