FAUNISTIC AND QUANTITATIVE ANALYSIS OF SPECIES OF THE GENUS PARAGUS Vesna Krsteska University”St.Kliment Ohridski”-Bitola, Scientific tobacco institute-Prilep Kicevska bb, 7500 Prilep. Republic of Macedonia. e-mail: vkrsteska@yahoo.com
ABSTRACT Larvae of the aphidophagous species of hoverflies play a significant role in regulation of the number of aphids on tobacco leaf. During the three-year investigations, we determined the following species of the genus Paragus: P. quadrifasciatus, P. tibialis and P. testaceus.The abundance of predatory species of the genus Paragus primarily depends on the abundance of leaf aphids, but since they are xerophytic and thermophilic organisms, climate factors play animportant role in their development.
Key words: aphids, aphidophagous hoverflies, P. quadrifasciatus, P. tibialis, P. testaceus |
